A. This is almost always a hardware related issue. If SCSI, there is probably a problem with termination, SCSI cables, the SCSI ID setting or power. In rare instances, the CD/DVD drive itself may be defective. The CD/DVD SpeedTools software supports virtually every SCSI and ATAPI CD-ROM, CD-Recorder and DVD drive available, so it is very unlikely that your drive is not supported.
To eliminate all possible hardware problems, you must methodically recheck all cables, termination (especially on PowerBooks), the SCSI ID setting, the power cord and make sure the CD/DVD drives power switch is on before you turn on you Macintosh.
To verify if your computer sees the connected CD/DVD drive, we have developed a special utility, affectionately named "Peripheral View" (now included with version 5.0 or later). Download and use the Peripheral View utility to test your peripheral configuration. The Peripheral View utility will identify all correctly connected SCSI/IDE/ATAPI devices attached to your Macintosh.
Note: If the Peripheral View utility can't see the connected CD/DVD drive, then the CD/DVD SpeedTools software or any other CD/DVD driver software will not be able to see it either. This means that you probably have a bad power supply, bad cable / ID / termination configuration or a defective drive.
The only software possibility for the "X" is that another driver has loaded for the CD/DVD drive before SpeedTools got a chance to load for it. To be sure this does not happen, boot your computer without any disc in your CD/DVD devices. Also, double check your Extensions Manager to make sure all other CD/DVD driver software has been disabled.
A. This usually means that the Apple file access extensions are not enabled or loading properly. Check your "Extensions" folder (contained inside your System Folder) and look for the following files: Audio CD Access, Foreign File Access, High Sierra File Access and ISO 9660 File Access (do not use the Extesions Manager to search for these files - it will not see them). These files are required resources for any CD-ROM or DVD driver to operate and if missing, will prevent all connected CD/DVD devices from mounting a disc on the desktop. If these files were not present in your "Extensions" folder, they will most likely be contained in the "Extensions (Disabled)" folder, also contained within the System Folder. To make them active, drag them from the Extensions (Disabled) folder into the Extensions folder and restart your computer. If you are using a System Software earlier then 7.5, these files may not be present in your System Folder at all. In which case, you should reinstall your System Software and make sure to enable the installation of the Apple CD-ROM software.
A. If you are using a SCSI CD/DVD drive, poor or improperly configured termination is usually the problem. To test for this possibility, remove as many other SCSI devices from your computer as possible. Restart your computer, and see if this provides better results. If it does, then termination is probably your problem. If you require assistance with reconfiguring your devices or termination, please contact the manufacturer of the CD/DVD device. Please do not submit this type of question to Intech, we are software specialists not hardware specialists.
Related note: Termination is especially difficult to configure properly on some "Mac Clone" models when installing three or more SCSI devices. Further, this particular problem does not seem to be remedied by installing an additional SCSI bus for some of your devices.
A. To achieve 24, 32, etc. times the data throughput of first generation CD-ROM drives, today's high-performance CD/DVD drives must spin data discs many times faster than they were ever designed to be spun. For example, the first generation CD-ROM drives spun discs between 210 rpm on the outermost tracks and 539 rpm in the innermost tracks, maintaining a constant 150 kilobytes per second. A modern 32x CD-ROM will spin a disc at a whopping 6720 RPM. That's well over 12 times the rate at which CD-ROM discs were originally designed to spin. As a consequence, the higher rpm rate greatly magnifies slight imperfections in the physical disc resulting in excessive vibration and noise-producing wobble. Drive makers do their best to dampen these vibrations, with varying levels of success. When you play an audio disc however, the noise and vibration will go away because audio discs do not need to be accelerated and therefore spin at the normal rate of 210-539 rpm.
A. If your computer is equipped with a secondary video out port (including TV cards), make sure that your primary or default monitor is set up as ID 1 in the monitors control panel. Sometimes secondary video devices like TV cards get setup from the factory as the primary video source, and you can't tell unless you check your control panel. The CD/DVD SpeedTools software checks the capability of the primary video source and then determines what color content to display. To correct the problem, use the "Monitors" or "Monitors and Sound" control panel and change the default monitor. This can be done by dragging the miniature menu bar in the Control Panel from one screen to the other. See your Macintosh's user guide for more information.
This answer consists of two parts: First, why does the OS 9 CD
not mount on my desktop? It appears that Apple has constructed
a slightly different CD format than that used in the past. As
a consequence, we too had to make a small change in our software.
The change has been fully incorporated in our CD-ROM SpeedTools
4.1 (or later) version available as free update from this web
site. Also, the OS 9 CD does carry a rather lengthy mounting time,
so be patient, it will mount.
On to the second part of this question... why can't I startup from the OS 9 CD? Many people who have tried to hold down the "C" report that the OS 9 CD does not automatically boot while others report no problem at all. To be honest, we're not exactly sure why some are effected by this problem and it appears that Apple isn't sure either. Apple has recently published a tech note telling those who experience this problem to first boot from their hard disk, insert, mount and select the OS 9 CD as the startup device in the Startup Disk Control Panel and restart. We have tried this solution and have verified that it does work for those who have the problem.
Also, If you are using a third party CD/DVD drive, you should know that not all CD/DVD drives are capable of booting a Macintosh. If you have tried the above procedure and still have problems booting from the CD, contact your CD/DVD drive manufacturer and ask if your model is capable of booting a Mac. For those who might be asking, no, it is not possible for us to solve this problem with a software driver, this ability has to be present in the drive's firmware.
Conflict Catcher is simply reporting our driver's overall memory
requirement. This message is displayed because of the memory that
our driver reserves for later data caching. Since the data cache
(reserved system heap memory) is not actually used at the time
of startup, Conflict Catcher thinks this memory is being wasted
and reports this as a potential problem, even though there is
no problem. We have discussed this mess.htmlage with Casady & Green
and we both agree that CD/DVD SpeedTools is doing nothing wrong.
The "Guarantee System Heap" feature in Conflict Catcher (which
reports the message) was not developed with the notion that a
driver (or other application) may need extra memory at some point
in the future. In fact, Casady & Green has fully tested our products
and calls the message "harmless".
If you find this Conflict Catcher message bothersome, Casady & Green recommends turning the "Guarantee System Heap" setting off to avoid the message in the future.
A. The Directory Cache feature in the CD/DVD SpeedTools Control Panel has useful trade-offs. Creating a larger directory cache setting can provide better performance while you are using data discs, but will increase the initial mount time for each disc. This is because upon inserting a disc, CD/DVD SpeedTools reads and saves disc directory data in to its cache. Obviously, this process takes extra time and the larger the Directory Cache setting, the more directory information it has to retrieve and thus yields longer disc mounting times. Having the directory cache set larger than 256K will best serve those with discs containing hundreds or thousands of files. If you regularly use discs with less than 100 files, or if you are looking to slightly improve mounting times, you will probably be better served by reducing the Directory Cache to 256K or lower.
Another factor that slows mounting time is discs that contain more than one session. Because of the way that discs are mastered, every added session increases the time it takes to mount. Unfortunately, this is a limitation of CD-ROM technology and is one of the few areas that CD/DVD SpeedTools can not improve your CD-ROM or DVD experience.
A. This is almost always a result of poorly configured termination on your SCSI bus. However, in some instances because of a poor firmware design, some CD devices cannot have media in the drive at time of startup. Doing so in these poorly designed drives, will result in hangs and crashes when booting. So, make sure not to have a CD in the drive when your first startup your computer. Lastly, it is possible that you may have our CD cache set too high in our control panel. Try turning both the Directory cache and Streaming cache OFF, restart and see if that resolves the problem.
The Apple CD/DVD driver only supports CD-DA on ATAPI drives. We
believe the reason for this is two-fold: First, all Apple computers
which shipped with an internal ATAPI CD or DVD drive are capable
of sustaining CD-DA playback (a new way of performing audio playback).
This is not true of Apple and other third party SCSI CD-ROM drives.
In any case, our 5.5 and higher CD/DVD SpeedTools versions will
allow CD-DA playback on almost all ATAPI AND SCSI CD/DVD devices.
However, there are some compatibility issues especially with SCSI
CD/DVD devices which need to be mentioned here.
First, we have noted choppy playback on drives connected to the Adaptec 2906 PCI SCSI host adapter card. This has to do with the way data is transferred through this particular card, and cannot be addressed by our driver (we've tried). On the other hand, the Adaptec 2940/3940 series cards we tested seemed to work well. Unfortunately, we are unable to test every possible SCSI drive on every PowerMac with every SCSI controller ever made, which means your SCSI CD-DA compatibility may vary. As a result, we encourage you to try our drivers before you buy!
Second, some SCSI drives are unable to fast forward and reverse using the Apple CD Audio Player. Is is particularly true of the SCSI Toshiba drives, but it may include other brands as well.
Third, not all drives can read audio fast enough to sustain a continual audio stream. We've tested some 8x SCSI drives which work fine, but we've had some 16x drives fail. For a short explanation of this phenomenon, please read a related CD/DVD Frequently Asked Question.
The bottom line is: For those who have a SCSI CD/DVD device which provides choppy or imperfect audio playback, your only remedy (via software control) is to turn off the "Digital Audio Playback" feature in our CD/DVD SpeedTools Control Panel. This will revert compatibility back to the older non-CDDA (analog) audio playback scheme.
A. Unfortunately, no. Booting is NOT a compatibility that can be given to a CD/DVD drive by using one driver or another. The ability to boot or not to boot comes directly from the firmware onboard the CD/DVD drive itself not from a device driver. If your CD/DVD device does not boot, consider contacting the CD/DVD drive manufacturer and ask them about receiving a possible firmware update that may allow your drive to boot a Macintosh.
A. Unfortunately, not. Like CD/DVD SpeedTools, DirectCD is a device driver. The Macintosh does not allow more than one device driver to control a device at a time. However, most people do not burn CDs as often as they read them. So, the work around for those who wish to use DirectCD for burning and who wish to use SpeedTools for their CD reading tasks will have to create multiple extension sets using the Extensions Manager Control Panel. Then you can toggle back and forth between CD/DVD SpeedTools and DirectCD device drivers depending on your requirement with a simple restart.
CDs which contains both audio and data info on the same disc are
called Enhanced CDs. Because the data portion is put before the
audio portion on these types of discs, it will make a device driver
(such as CD/DVD SpeedTools) think that it is a data only CD. As
a result, CD/DVD SpeedTools will mount only the data portion of
the disc automatically when inserted. However, CD/DVD SpeedTools
also provides an exclusive feature to mount the audio portion
of the disc too - as if it were a common audio only CD. The feature
works by forcing the CD/DVD SpeedToold driver to manually look
past the data portion of the CD for audio information that may
be contained there. If it finds audio information, it will mount
and treat the information like a common audio CD. To invoke the
audio mounting feature, hold down the "Control" key and insert
the Enhanced CD. CD/DVD SpeedTools will then mount it as if it
were a common Audio only disc. To have CD/DVD SpeedTools treat
the disc as a data only CD again, eject the disc and reinsert
it again as normal without holding down the "Control" key.
A. The answer is that CD/DVD SpeedTools doesn't use an Extension file to load its drivers. Many people do not realize that a Control Panel file (like we use) has the exact same properties as an Extension file except that additionally, a Control Panel can allow for user modification/configuration (such as for cache settings). The CD/DVD SpeedTools driver is actually contained in the Control Panel file itself and therfore, does not need an Extension.
First, we'll define the purpose behind the "Search & Load" button
feature and when its a good time to use it. The "Search & Load"
button is for loading drivers only after boot time such as when
you connect a new device after boot or if another program closed
the driver, but did not reopen it like CD-Copy
does. Another good time to you it is when you add a CD/DVD device
in the MediaBay of a PowerBook after boot time. If your CD/DVD
device is connected and powered on at or before boot time, a CD/DVD
SpeedTools driver will be loaded for it automatically (if your
drive is supported) and you shouldn't need to use the "Search
& Load" button.
The "No driver could be loaded" message will appear if you use the "Search & Load" button and all supported CD/DVD devices found on your computer already have a driver loaded for them such as if CD/DVD SpeedTools loads one for them automatically at boot time. Another reason that the message would be presented is that no CD/DVD devices that are compatible with CD/DVD SpeedTools could be found on your computer (this is the least likely of the two reasons because CD/DVD SpeedTools support nearly every ATAPI and SCSI CD/DVD device out there).
A. The -17 and -50 are generic control errors n, and unfortunately are not extremely informative. If you get one of these errors during QuickTime-based audio extraction (like SpeedTools uses) it always means that the CD/DVD drive reported an error during the extraction request. This could be due to a number of factors including, but not limited to: dust, excessive scratches on the disc, or a flaw in the recorded surface of a CD-R disc.
Toast audio extraction is preferred over QuickTime audio extraction by audio professionals for two reasons:
- It's faster than QuickTime extraction.
- It checks for data continuity between audio blocks. If Toast finds an audio extraction continuity problem, it will report those pesky -17 or -50 errors. That's the bad news.
Now the good news: Intech has worked closely with the good folks at Adaptec and we believe that we have come up with the most robust audio extraction routines possible. We still cannot guarantee error-free extraction with Toast or even QuickTime because there are just too many factors beyond software control. However, if you were getting -17 and/or -50 errors before, we encourage you to upgrade to our newest release. Click here to get the latest CD/DVD SpeedTools release. Additionally, we at Intech would like to welcome those of you who are joining us from the dark side of the force (owners of FWB's CD Toolkit product), where these kinds of errors are frequent and inevitable.
A. To create a bootable CD, Toast needs to extract the CD driver resource from the Apple CD/DVD Driver extension. Toast will automatically look for the Apple CD/DVD Driver in your Extensions folder. If it was unable to find it, Toast will post a message telling you this and will also provide an option for you to look for it. All you need to do is to tell the Toast application where to find it for this use. If you used our installer program, the Apple CD/DVD Driver was moved to the "removed drivers" folder inside the installed "CD/DVD SpeedTools Extras" folder.
A. In addition to having a Toast compatible driver for your drive, Toast needs to recognize the drive and model number itself too. This is because there are many CD/DVD devices out there that have unique firmware traits and/or flaws about them. To compensate for possible issues involving these traits and flaws, Toast must provide individual "write" support for each drive from within its own program. The remedy for this problem is to contact Adaptec/Roxio and ask them for support for your particular CD/DVD model.
A. We asked Adaptec about this message and the reason they gave to us was that they do not officially support any third party driver installed for a CD-Recorder. Be assured however, that no problems have ever been seen or reported while running SpeedTools drivers on a CD-R or CD-RW while mastering with Toast. When you see this message, just click "OK" to contine.
CD-Copy(TM) closes our CD/DVD driver when you master a CD. Since
they do not re-open our driver when the program quits, there is
nothing the SpeedTools driver can do since it has already been
removed from memory.
We have talked directly to Astarte about this problem, and even offered to send them some of our source code showing them how to properly re-open our driver.
They refused to take us up on our offer.
Unfortunately, this means your only option is to restart your computer when you are done mastering so SpeedTools can load into memory again and mount your new session. If you don't like rebooting every time you master a CD, Intech strongly recommends you use Toast software from Adaptec.
Intech's official position on this matter is that CD-Copy is just plain doing things the wrong way. Astarte tells us that the reason they close the driver is to keep the driver from polling the drive while the drive is busy mastering a recordable CD. If the driver polls while data is being written to a disc it could cause a buffer underrun and ruin the session. However, back in March of 1999 Apple officially documented a means to tell a driver not to poll a device. Apple did this in their update to the "DV22 - CD-ROM Driver Calls" tech note.
The March 1999 update to TechNote DV-22 formally documented a new control call called "Quiescence." The sole purpose of Quiescense is to prevent a driver from polling a drive while a program is trying to master a recordable CD. (We know because we were one of the companies which adopted it before Apple even knew that several developers had gotten together and created this call.) Now, it seems as though CD-Copy is the only CD mastering software for the Macintosh which DOES NOT incorporate this call.
What a recording software SHOULD do in a situation where it does not want buffer underruns to occur is to issue the Quiescense control call to the CD/DVD driver. If the driver returns an error, THEN AND ONLY THEN should the recording software close the driver to protect against buffer underrun. If the driver does not return an error, then the driver supports Quiescence and will not interrupt the drive while it is mastering.
So why does CD-Copy work with the Apple driver? Frankly, we're not sure why they chose to support them but exclude others. However, if they would just use the Quiescence call like they are supposed to, this would not even be an issue and we could remove this FAQ from this web page today!
Note: starting with the 4.5 version of CD/DVD SpeedTools, most of the time you can reinstall a CD/DVD driver which has been closed by CD-Copy. Unfortunately, since the driver is being loaded after boot time, directory and streaming caches cannot be allocated. This is the absolute best we can do about this situation.
A. A drive's speed rating only applies to data CD's which conform to the Yellow Book standard (i.e. HFS, ISO 9660, High Sierra, etc.) The information on Digital Audio CD's (CD-DA) is based on the Red Book standard which arranges data very differently than Yellow Book data CD's.
Essentially, it is far more difficult to position the optics exactly at a desired location because Audio CD's provide fewer "markers" on the disc for the drive to know where its optics are currently reading from. To compensate for the lack of optical position information, most drive manufacturers dramatically reduce the rotational rate of a disc when performing Digital Audio Extraction (DAE), thus reducing the speed at which CD-DA data is transmitted.
Plextor(TM) drives are a notable exception, however. Plextor drives typically see extraction speeds reach about 50% of the rated speed of the drive!
A. This is usually a problem that involves the quality of the CD-R or CD/RW media and/or the laser strength of your CD/DVD device. Unfortunately, no driver will resolve this. However, there have been a few reports that have indicated that switching to other CD-R or CD/RW media brands have yielded better results when used with some CD/DVD devices for reading purposes.
A. Normally, SpeedTools will mount only the Macintosh session of a Mac/ISO combination CD-ROM. Thus the PC session will not be accessible to a PC emulator. However, SpeedTools provides many powerful on-the-fly mounting options which solves this and many other issues relating to mixed-format CD/DVD discs. Please see the "Mounting Non-Macintosh Discs" section of our user's guide if you have SpeedTools version 4.5 or later or the "User's Guide Addendum" file for versions prior to 4.5 (installed in the "CD-ROM SpeedTools Extras" folder) for detailed information on how to use our on-the-fly mounting technology.
A. The two most likely explanations are:
First, you might be missing the foreign file handlers in your extenstions folder. In particular, make sure your "Foreign File Access" extension is set to load at startup.
Second, your CD-ROM disc might be a Microsoft variation of the ISO-9660 standard. There are two Microsoft variations of the IS0-9660 format: Romeo and Joliet.
Please note that many of our customers have reported success accessing Romeo and Joliet discs while running a PC emulation program on their Mac.
A. If data CD's mount but audio CD's do not, you are missing your "Foreign File Access" and/or your "Audio CD Access" files from your extensions folder. To fix the problem, locate those files and put them back in your extensions folder, or reinstall your MacOS System Software.
A. Many CD-Recording software products install their own device driver like Toast (tm), which installs a file called "Toast CD Reader" in the Extensions folder. CD/DVD SpeedTools will support most known CD-Recorder drives, but you must first remove the driver that was provided with your recording software.
A. No, unfortunately it is just not possible. It does, however, disable many commonly known CD-ROM and DVD drivers. A list of these drivers is contained inside the installer program code. Many CD/DVD driver companies occasionally change the name of their driver extension files and/or include product revision numbers in the file names. This practice may prevent the CD/DVD SpeedTools installer program from seeing a match and recognizing that another driver is set to load at startup. If you suspect that another CD/DVD driver may be loading instead of CD/DVD SpeedTools, double check both the Controls Panels and Extensions folders for other possible CD/DVD drivers and remove them manually.
A. Software that scans for viruses and/or system software conflicts may prevent some startup icons from appearing during the startup process or may only present the application icon itself. These programs don't generally harm or disrupt our CD/DVD driver from loading properly, but if you are having problems with your CD/DVD drive, they may hide what might otherwise be very helpful information.
A. The easiest way that we've found, was to look in your Control Panels and Extensions folders for any file that contains "CD" or "DVD" somewhere in its name. Here's the exceptions: CD/DVD SpeedTools (control panel) and Audio CD Access (extension), these files should remain. Any other file that contains "CD" somewhere in its name is probably a CD driver and should be removed if you want CD/DVD SpeedTools to control all of your CD and DVD devices.
A. If you get this message, obviously CD/DVD SpeedTools did not load for at least one of your CD or DVD devices. Usually, this means another driver has loaded before ours. Please read the < a href="CDFAQ.html#Q21">previous FAQ above to help locate the other driver.
A. Our Cache Monitor program can only track the cache information for drives that CD/DVD SpeedTools controls. A missing drive indicates that CD/DVD SpeedTools is not controlling that device and that another driver probably is. If you want SpeedTools to control this device and track its cache information, you will need to find and remove the other CD-ROM and/or DVD driver from your System Folder. Please read one of our previous FAQs above to help locate the other driver.
A. The Cache Monitor program has been designed to display data CD cache hits exclusively.
