IBM Thinkpad 600X - Device Mgr will not recognize CD-Rom

By jtlo38 ·
I am running WinXP-SP3. My CD-Rom suddenly stopped working. Device Mgr says I have a Floppy Drive installed and I cannot get it to recognize (list) the CD-Rom that 'IS' in the bay. I do not have a Floppy Drive.
I have reset BIOS and no help. Has anyone encountered this problem and, if so, how do I correct it??

Thanks & HELP !!

CD Software

by shasca In reply to IBM Thinkpad 600X - Devic ...

I have had the Creation Software cause this issue, and I have also had corrupt OS cause this issue and read/write errors.

This is if in fact the drive has not failed mechanically. Have you done anything to verify the drive works. Like putting in another case?

Is it being detected in the BIOS

by Jacky Howe In reply to IBM Thinkpad 600X - Devic ...

Have you removed and reinserted the CD-ROM drive. You may have to remove a security screw to be able to remove the UltraslimBay device.

After reinserting the UltraslimBay device check the BIOS to see if it is detected. If it is not being detected it has more than likely failed and will have to be replaced.

If it is detected in the BIOS but not showing in Device Manager try this for clearing the Upper/Lower Filters. Save a Backup of the keys before proceeding.

Click on Start, Run and type in 'regedt32' and press Enter
Expand the "HKEY_LOCAL_MACHINE" key by clicking the "+" next to it.
Expand the "SYSTEM" Key
Expand the "CurrentControlSet" Key
Expand the "Control" Key
Expand the "Class" Key
Look for a key containing the following string of letter and numbers:{4D36E965-E325-11CE-BFC1-08002BE10318}
High light this key by left clicking on it
On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these Keys delete them by right clicking on them and choosing "delete" exit the registry.
Restart your PC.

If the drive is not present in the Disk Management window or if you are not able to access it, then the drive may have failed. In this window you should see all of your connected physical drives, their format, if they are healthy, and the drive letter.
