CD Rom not recognized by OS
Hi,
I have just reinstalled the OS on my older pentium. The CD-Rom worked to install the OS, but now that I am in the OS (Windows ME) it can see the CD Rom drive, but cannot read any CD. Sometimes it recognizes data CDs to see the name (IE it shows the Windows ME name when that disc is in). Most of the time it doesn't recognize the CD or thinks it is an audio CD. Eject the CD works 100% of the time, even from w/in Windows Explorer. I have changed the CD Rom, to one that I recently tested on another machine, same thing. Any ideas? Thank in advance, |

From your report, I'm not sure whether you mean that it's the CD-ROM
(player) which isn't being recognised by the OS or rather, - as I suspect - the CD (media) itself - your Subject title implies the player, which is a slight (but important) difference. If you mean the CD's (media), your CD-ROM drive *may* be beginning to fail (They do!!) However, you need to try to eliminate WinMe as a possible cause of this problem by checking that the CD-ROM works in Real Mode DOS. To confirm that you can 'read' CD's in Real Mode DOS :- Boot, using your WinMe Startup (floppy) Disk in the A: drive. Select option 2. Start computer with CD-ROM support. Let the screen information scroll until you eventually see a line which should report a drive letter for the CD-ROM - but note that it may not necessarily the same letter as you would expect to see in Windows. For example, you may see the CD-ROM, becoming the E:, so the screen should show: Drive E:= Driver MSCD001 UNIT 0 Your CD-ROM Is Drive E When the boot disk finally settles down, you will be presented with an A:\ prompt. Now put a (data) CD into the CD-ROM and at the A:\ prompt, type "E:" (no quotes and note the colon after the letter E) Then Press Return. Now, at the E:\ prompt, type "DIR /P" (no quotes and note the space) Then press Return. You should see a listing of the CD contents. Try this with several CD's Come back with your results.

Mart,
I suspect that ME is the problem, I tried reading a couple of CDs in Real DOS mode, and they read fine (was able to browse the directory trees, change dirs etc.) I then tried the same CDs in Windows, and the system thought that they were Audio CDs and tried to autoboot Media player.

OK, Dave - then ASS-U-ME-ing that you don't have any 'oddball' CD-ROM
software/utilities, my next suggestion is to have a look in Device Manager at the CD-ROM and IDE controllers to see if there are any conflicts or error reports. The drivers may even be damaged/corrupted. It *may* have just been due to a 'bad' installation of WinMe - I hope g If so, it might also be necessary to delete/remove any/all of the above in Device Manager (again, in Safe Mode) - N.B. Although you *should* be able to see the CD-ROM in Dev.Man. in Safe Mode, you won't be able to see (or use) it in Windows Explorer of course - the drivers are only loaded in Normal Mode. Then re-boot and let WinMe re-detect and load the drivers. Mart "David McKinnon" wrote in message news:1qyae.46123$yV3.25479@clgrps12...

Hi,
Check the CDROM driver, if possible update/upgrade it. If CD-ROM works in another computer but not on yours, you'll need to check: * BIOS settings: choose Auto works * Check if CD-ROM is configured as Master/Slave or Cable Select. There is a jumper to do this. * Check for faulty cable. * If is a modern CD-ROM, be sure DMA is enabled (driver properties). Good luck, Daniel Interdesigner Software Development http://www.interdesigner.com http://www.comparatorfast.com http://www.networkclipboard.com http://www.shutdowntools.com ICQ # 61133529 "David McKinnon" wrote in message news:xaiae.55869$VF5.51603@edtnps89...

For your information:
Would you please check for the cable, if the problem still exist, there might be some problems with the port on you mainboard. Max.Bao |
