Two CD drives knocked out after power surge 1

[Amos43]

Hi guys, I appreciate your help.

My device manager shows that both my CD drives have error 41, which says that although Windows loaded the software drivers for the CD drives, it cannot locate the hardware itself.

This followed two power surges that restarted my computer. The strange thing is that both drives show the same error, and that nothing else is wrong. Before I assume that both are fried, could you guys hypothesize what else could be wrong?

I tried to reset BIOS settings (BIOS detects the drives), to disable/enable and reinstall the drives, and replaced the data cable. The drives are not dead - the LEDs flash as usual and both open and close normally. It's just that Windows cannot find them.

Details:
* Sony CD-RW CRX230-ED
* Combo IDE6216CO CD-RW/DVD
Both use the same IDE and power cables

* Windows XP SP2, latest updates and drivers

See if this helps:
Start Registry Editor (Regedt32.exe).
Locate the UpperFilters value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
On the Edit menu, click Delete, and then click OK.
Locate the LowerFilters value under the same key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
On the Edit menu, click Delete, and then click OK, and quit Registry Editor.

If no luck and both CD-ROM drives are connected to the same IDE cable, then shut down the system, and disconnect one of the drives. If the connected drive is now seen by Windows, then the disconnected one is bad.
If the connected drive is not seen, then disconnect it and reconnect the other one. If the connected drive is seen, then the disconnected one is bad.

If neither drive is seen by doing the above, then see if they work on another system. If not, then they're probably bad.

I had a similar problem that solved itself after I unplugged the machine for 1/2 hour. It wouldn't see either disk drive after the power shortages. I was surprised that it worked after unplugging it, though. I had only done warm boots after the outages.

That's one of many reasons that a UPS is a very good idea.

The problem was that 5 minutes after the shortage, I turned it back on, only to experience a second shortage. What are the odd? I agree that a UPS wouldn't be a bad idea, but I'd need a few of them, as cpu's are spread around the place.

Thanks for the tips guys. Yes I have a UPS, I was actually surprised it failed two times in a row - usually it's just fine.

Dammit Ski, you're a genius. Both my drives work right now. Thanks, I really appreciate it.

You're welcome. Glad to hear that you fixed things.
Like they say "Some days you eat the bear, and some days the bear eats you." Hope that bear tasted good.
