My DVD ROM and DVD/RW on Secondary IDE have vanished within windows.

My DVD ROM and DVD/RW on Secondary IDE have vanished within windows.

I think this is related to me hooking up an external USB drive.

I have done all the obvious stuff; uninstalled all the other stuff.  Uninstalled the DVD and DVDRW.

The BIOS sees it and I can boot to CD, they're just gone in Win XP pro.

Ideas of a fix other than a reload???????

Thanks in advance!!!!!!!!!

Do they come back when you remove the USB drive? In any event force the USB drive to a drive letter well away from the auto settings. With it plugged in, open Administrative Tools, Computer Management, Disk Management, and set it to Z. Reboot. If the other drives haven't reappeared, do the upper/lower filter fix as follows -

Remove upper and lower filters :
In Regedit,
On the right hand side of the window, click UpperFilters. Click Edit on the menu bar. Click Delete, and then click OK. On the right-hand side of the window, click LowerFilters. Click Edit on the menu bar. Click Delete, and then click OK. Reboot.
