Old cdrom stopped running at high speed
dblotii Jan-03-02 09:56 PM
My toshiba 12x cdrom has stopped auto loading software cd's but will still autoplay music. It also will transfer data at the slowest speeds. It is actually slower than the floppy! I have checked everything, bios, drivers, etc. The only unusual thing I have found is that in config.sys the following line:
devicehigh=C:\CDROM\CDROMDRV.SYS /d:mscd001
Shouldn't it be device, not devicehigh?

Try remarking it out if you have Windows 98 or higher installed (put a rem plus a space in front of the line). Likewise remark-out any line in the autoexec.bat file with mscdex.exe in them. You can always revert back that way. Newer versions of Windows usually do not need the real mode (DOS) drivers. In fact, unless you have some really old stuff in your computer (hardware and software, e.g., old games) these versions of Windows do not need the config.sys and autoexec.bat files and you may be able to
C:\>ren config.sys to config.dux and save some boot-up time. Be sure DMA is enabled, if the drive will support it (http://duxcw.com/digest/Howto/cdrom/cdrom2.html and http://duxcw.com/faq/win/2kdma.htm), a 12X drive may or may not. The drive could have dirty laser and most of them cannot be successfully cleaned with kits available at Radioshck, etc. (these kits can actually damage drives). Look for pronounced scratches on the CDs. CD-ROM dries are very good at error correcting small defects on CDs, but gouges can slow them to a crawl as they repeated try to read damaged parts of a files. See http://duxcw.com/digest/Howto/troubleshoot/cdrom/autoplay.html.

Another one of “Larry’s rules” learned the hard way: CDs like floppies belong in only one of three places: in your hand, in the drive, of in a protective envelope or plastic case (much preferred for truly valuable ones). And, as long as I’ve started still another lecture, additionally, for floppies, away from anything magnetic (magnetic tools are banned in my shop). Larry

I did buy a new drive, but before i install it I would like to know if the problem is software or hardware!
This is on an old 200 mmx machine with Windows 95b. I plan on installing Win 98 as soon as I understand what my cdrom problem is.

I don't believe that the "how to troubleshoot autoplay applies here since autoply works perfectly with an audio cd, but not with software.

Well now, the auto play for music is a lot diff then software autoplay.inf. With the music nothing is gonna be placed on the hard drive + music plays best at 4X anyway. Can you imagine trying to load office 2k with a four speed, nah.
How much space is on the C drive? When you ask to install from the cdrom it looks for space + a buffer area for extraction of certain batch files. So how is that c:\windows\temp folder? Full of tmps? What? How many mb you say? getum gone.

I've got more than 7 gigs of space left on the hard drive.

Guess I should read my own articles before referencing them… I thought it covered both. Not all software CDs have an autorun.inf file and will autostart; most do. Start, Settings Control Panel, System, Device Manager, double-click the CD-ROM, Settings, check Auto Insert Notification, OK, Close, Yes to restart your computer when prompted. Larry

Auto insert notification is already selected. I have tried many software cd's and none of them will autoload any longer. Is it possibel that this is a software problem and not a cdrom drive problem?
