CD-ROM not working anymore

On my Windows95 computer I've been using my CD-ROM for about a year now with no problems. Recently I started to not beeing able to access my CD-ROM drive. Every time I go into the Windows Explorer to try to view the CD-ROM drive I get the "Error accessing drive - Retry or Cancel".

I took the drive out of my computer and installed it on a different one and was working fine; Win95 detected and installed the drivers just fine.

I put the drive back on my computer and re-installed it. The same problem.

If I use F8 and boot to DOS and than I load the MSCDEX manualy (by typing it at the C: prompt) I can access the CD-ROM drive fine but ... if I continue to type WIN to load Windows95 than I have the same problem.

Any ideas on how to solve this?

P.S. There is no new software that was installed as far as I know.

First thing to try is:
- enter Device Manager
- remove CD-ROM
- reboot and let Win95 redetect it

If no go, try this:
- backup files from folder \Windows SYSTEM.DAT and USER.DAT
- put them into some directory for safety, they are your registry
- run Regedit from \Windows
- find line "ideatapi.mpd"
- make sure that found line accompany CD-ROM location (which IDE)
- replace this line to "esdi_506.pdr"

Thank you.
Can you provide more explanations on the last steps? I would like to understand what and why I'm doing it before I do it.

Last steps replaces serving controller which involves so-called
"bus mastering" to Standard IDE/ESDI controller. This is usually
helpful for PIO-only devices non-properly recognized by BIOS.
Bus Mastering means utilization of DMA (Direct Memory Addressing)
controller for direct information transfer between media and RAM
without using CPU. PIO-only devices (90% of all CD-ROMs) not
supported with busmastering.

Sorry, if it sounds techie for you. I'll explain all point if
needed.

If you have your CDROM boot disk: Make sure fdisk is on the disk and Boot with it and type in "fdisk /mbr". If you don't have the CD disk: use your WIN95 start disk and add "fdisk" to it. In my version of win95, it's in windows\command folder

Worked for me.
