PC Can't "Find" by CD Drive 1

[Skl]

I have lost my D drive on my computer - how can I get this back?

 

[edfair]

IF it is working correctly it will be found automatically by windows95 and up. If it is broken then it disappears.
Suspect that it might be broken. But post some system info and we'll see what can be found.

Any advice I give is my best judgement based on my interpretation of the facts you supply.

Help increase my knowledge by providing some feedback, good or bad, on any advice I have given.

If it has disappeared from Windows, try the "Add New Hardware" and see if it shows up. If not, there are quite a few reasons it won't.
The Busmaster drivers could have become corrupted, in which case you may also lose use of your hard drive.
The CD-ROM itself has quit working electrically, unusual, but it happens. Check cables and such.
Your configuration may have changed and the hard drives are running in DOS compatibility mode.
Take a look in autoexec.bat and see if there's any reference to mscdex.exe and look in config.sys at the same time. If they're there, remove any "REM - by windows setup" stuff, save and restart. This isn't too likely, but possible. Cheers,
Jim

I had a situation were the cd rom had disapeared in windows I new the cd rom drive was okay because I used start up disk and booted into the cd rom you could also boot your windows cd rom from your bios. If you find that you can read the cd rom's this way I found the below fix on microsofts knowledge base helped me just print it of and follow the instructions.

The knowledge base article is Q190303

I hope this is some help to you.

Determining If the Real-Mode CD-ROM Drivers Work
Before you configure your computer to use the real-mode CD-ROM drivers from the Startup disk, verify that the drivers work with your CD-ROM drive. To do so, follow these steps:

Restart your computer using the Windows 98 Startup disk. On the Startup menu, choose Start Computer With CD-ROM Support.


Insert a CD-ROM into the CD-ROM drive.


Type dir <drive>:, and then press ENTER, where <drive> is the drive letter for the CD-ROM drive. Note that the CD-ROM drive letter may be one letter higher than you expect.


If you can retrieve a directory of the CD-ROM, the real-mode drivers work with your CD-ROM drive. If you cannot retrieve a directory, you must use the drivers included with your CD-ROM drive.

Using the Startup Disk Real-Mode CD-ROM Drivers
To configure your computer to use the real-mode drivers from the Startup disk, follow these steps:

If you have not already done so, restart your computer using the Windows 98 Startup disk.


Create a new folder on your hard disk and then copy files to the new folder. To do so, type the following lines, pressing ENTER after each line:

c:
mkdir rmcd
cd rmcd
a:
copy aspi2dos.sys c:
copy aspi4dos.sys c:
copy aspi8dos.sys c:
copy aspi8u2.sys c:
copy aspicd.sys c:
copy btdosm.sys c:
copy btcdrom.sys c:
copy flashpt.sys c:
copy himem.sys c:
copy oakcdrom.sys c:
copy c:\windows\command\mscdex.exe c:\rmcd
c:
dir

There should be 11 files in the new folder.


Make backup copies of your Autoexec.bat and Config.sys files (if they exist). To do so, type the following lines at the command prompt, pressing ENTER after each command:

c:
cd \
copy autoexec.bat autoexec.sav
copy config.sys config.sav


Type edit autoexec.bat, and then press ENTER.


Add the following line to the Autoexec.bat file:
lh c:\rmcd\mscdex.exe /d:mscd001




On the File menu, click Save, and then click Exit on the File menu.


Type edit config.sys, and then press ENTER.


Add the following line to the Config.sys file:
device=c:\rmcd\himem.sys /testmemff

NOTE: If the Himem.sys line already exists, do not add the line above.

Add the following lines to the Config.sys file:
device=c:\rmcd\oakcdrom.sys /D:mscd001
device=c:\rmcd\btdosm.sys
device=c:\rmcd\flashpt.sys
device=c:\rmcd\btcdrom.sys /D:mscd001
device=c:\rmcd\aspi2dos.sys
device=c:\rmcd\aspi8dos.sys
device=c:\rmcd\aspi4dos.sys
device=c:\rmcd\aspi8u2.sys
device=c:\rmcd\aspicd.sys /D:mscd001
device=c:\rmcd\flashpt.sys
files=10
buffers=10
dos=high,umb
stacks=9,256
lastdrive=z




On the File menu, click Save, and then click Exit on the File menu.


Remove the Startup disk and then restart your computer normally.


Known Issues
The following list contains known issues with the real-mode CD-ROM drivers on the Windows 98 Startup disk:

CD-ROM drives connected to sound cards may not work properly.


Early proprietary CD-ROM drives (for example, Mitsumi, Panasonic, Sony) may not work with the drivers on the Startup disk. Some older IDE controllers also may not work.


The SCSI drivers on the Startup disk support most Adaptec, BusLogic, and Mylex adapters. Other SCSI CD-ROM drives may not work with the drivers on the Startup disk.


If your SCSI controller is configured for a non-default input/output (I/O) range, the drivers may not detect your SCSI card. Consult your SCSI driver documentation for the default I/O ranges for your card.

For additional information on troubleshooting SCSI devices, please see the following article in the Microsoft Knowledge Base:


Q133285 SCSI Setup &amp; Basic SCSI Troubleshooting in Windows
Drivers are not included for any PC Card (PCMCIA) CD-ROM drives.

One thing you might want to check is under your Device Manager make sure the CD rom doesn't have it's own drivers and went into the &quot;Other Devices&quot; section. I had a cdrom once that I removed and on reboot it went into the other devices.

Best of luck!

According to me this may be the problem with the power supply.Remove your pc cover and change supply cable with the rest.Most of the motherboards will auto detection capability.after changing the cable you start the computer and go to setup.From there you go to auto detect ide.In most cases it will detect.Save to cmos and exit from there.When restarting you go tocommand prompt by pressing F8 key.From there you take the choice &quot;command prompt only&quot;.At the command prompt you type &quot;edit autoexec.bat&quot;.When there will be one line containing &quot;mscdex.exe&quot; .You erase the words or line which are comig before this line. Save the file and exit. I think it will solve your problem. Is this problem persists i have to check your computer to say more

Hi,

I have an old 486 with all ISA slots. I have reformated and booted up with the Windows 98 Emergency Boot Up Disk. This is so I can istall the operatingg system. When the disk has finished loading I get the following message.

Device driver not found: 'MSC001'
No valid CDROM device drivers selected.

Could you please point me in the right direction.

Just look for Mitsumi CDROM drivers on the internet and download the drivers and try that. They have worked with every CD I have used yet. If you do not like my post feel free to point out your opinion or my errors.
