Anyone ever had their cd-rom drive just disappear from windows? I have a machine that is running Win98, everything is running just fine but Windows does not recognize that there is a Cd-Rom drive. Yet, I can jump into a DOS window and look at the CD just fine.
Other than formatting and starting all over ... I am at a loss.
Any help would be appreciated.
Thanks!

Check your hard disk contollers in windows device manager and see if you have any problems there.

Device manager sees everything just fine, ... yet Windows, itself does not.
Wierd Science.
Have you checked under performance to see if your running in 16bit compatipility mode ?

Yes, and no it is not. Like I said, its running as close to normal as it can. Except for this one thing.
------------------
Run an anti-virus program on it.. I've had this happen several time and that's what caused it.
------------------
If all else fails.. boot it.

Agree...
Also look at similar topic: http://www.windrivers.com/cgi-bin/fo...ML/001757.html
when this has happend to me i first run the add hard ware wizard( sometimes it works) or i take the rem out of the autoexec.bat file for the cdrom, boot it up once then rem the cdrom line back out and reboot and it stays there.
Tried all those great suggestions, nada. CD-Rom is now master, HD is slave. Still no CD shown, although the device is there. Nothing in the autoexec.bat or anything else... whacky I tell ya.
Have you somehow gone into the driver properties and clicked the "Hidden" attribute or the "Do not show this drive in Windows" check box that you can click on harddrives? you may check it out..
As it seems to me from Your last post , You used CDROM and HDD both on same IDE channel.
Right?
So, try to use CDROM and HDD on separated IDE
channels (HDD -1, CDROM-2).
Ok, try this...it's worked for me plenty of times.
Go to your Config.sys file and open it as a text file in order to add the following line:
LASTDRIVE=Z
Thats it. You can add this line in anywhere and it will work. This allows Win9x to see all the drives you have installed. Hey, sometimes the old way still is the best way! Good luck.
Agree with NightVa - sometimes it's helps me too.
During installation Win9x always REMmed this.
But it's usefull thing in case if You using multyconfig with DOS networking,DOS CDROM etc.
There are two hard drives in the system, a ZIP internal, and the cd-rom. All of which have worked fine up until recently when the Cd-Rom disappeared. Whacky.
So I cannot just run the HDD-1, Cd-Rom-2. And the lastdrive statement is in ...
I am ready for a format. =)
Have you got windows cabs files on your hard disk? Try re-installing windows without re-formatting
Installing Windows over Windows? ... wouldn't that cause a problem somewhere? Especially with an established registery, etc.?
Best way to reinstall Windows over Windows without damaging or losing settings in the registry yet getting the cleanest possible install as well is to rename the win.com file in the Windows directory, reboot to a DOS prompt and run the setup.exe on your install CD or better yet, copy the WIN9x directory from the CD to the HD and run the setup from there. One important note: when it asks for the install directory it will default to C:\windows.000. Simply choose other directory then remove the '.000' from the path and you're off, just like a clean install without losing all your settings.
i my not be the most experienced tech here, but before i would reinstall windows i would boot to win98 floppy with cd rom support and see if it finds the cdrom. have you considered the cdrom has gone bas.
just install tweakui and go to the drives tab? anyway, uncheck the "hidden" drives there, too many people like to hide drive letters and it makes for this kind of problem when drive letters change.
I agree with Techs I would try a different cdrom first to rule out that it is a bad cdrom.
It is not a bad cd-rom.
All scenario's have panned out empty. Its a ghost in the machine.
Weird.
Thanks though.
The one thing I don't see is a mention of the CD driver being loaded in config.sys. A '.sys' file for the CD in config.sys will usually keep the CD from appearing in device manager yet still enable the drive to work in a DOS window.
You might want to update your bios and controller drivers. Seems that the driver that windex is trying to load for the cdrom is not compatible. what brand is the cdrom anyway.
------------------
hey its me again!
The CD-ROM works perfectly well, in a DOS mode/window. The device is listed as A-OK in device manager.
Current drivers are present and accounted for. The drive is a base mitsumi 24x.
I don't want to sound like a tech. show freak, but I have done all the things that field experience and schooling has given me - and all of your great suggestions.
This thing is just gone.
------------------
after being a tech for two years i have found out that sometimes the answer is "I don't know".
Hi,
I know you said you messed with the autoexec.bat file in c:\ directory...not c:\windows. Verify that you have the following: "MSCDEX /D:MSCD001 /L:M"
--where /D: is the device driver and /L: is the letter of the CD-ROM drive. It is usually set to "D" but HP's Pavilions usually set them to "M."
Also, do as NightVa said...make sure that config.sys has "LASTDRIVE=Z".
Save changes and reboot...go to Control Panel and the CD-ROM should reappear.
Hope I'm not rehashing old info...I know that I had the same problem tho.
Good Luck!

Ok... I've had a similar problem once... something to do with a bad plug and play chip in the cd-rom itself (I'm guessing) have you tried a new cd-rom? It may just be that simple... but if not.. here's another suggestion.
Boot into Safe Mode (by pressing F8 when it say's Starting Windows 9x) and goto the device manager and remove all instances of duplicated items.. i.e. if there are more than one cd-rom listed in there delete both of them.. and you may want to delete the cd-rom out of there regardless this has cured many problems I've had with other hardware.
is there anything you've changed prior to running into this problem? even something small.
well I hope this helps.. seems you've got a lot of really good suggestions already... but I honestly feel that the drive has just had it...
best of luck

1. Make sure the cab files are on your hdd
2. Boot to Safe Mode (very important)
3. Go into Device Manager
4. Remove all cdroms
5. Remove all the IDE controller stuff that Windows will allow you to remove
6. Reboot normal and let Win find what is there
Try the above first but if all else fails delete the "Enum" key from hkey_local_machine before you resort to wiping the drive and reinstalling...

Guys- He has said that it works if he drops to dos. My conclusion from this is the CD WORKS....Also that config.sys / autoexec are good.... that would mean that something on the 32-bit side is hosing this thing. The only time i have had problems like this are either when the novell client is over mapping drives via login scripts, or if the users local and or network stored profiles are hosed....ie just deltree c:\windows\profiles\%USERNAME%....and the one stored on the network end to.....but since i think this system is yours at home, i doubt either of these fixes will apply to you....so my fix in that case would be
format c: /q
haha Have Fun...
