I am having problems reading drives when I go into "my computer". I have a CDRW,a DVD, and 6 different card readers.Initially it will show the drive letters fro the CD and DVD as E &F which are right but I am starting to get situations where I check it out and they are gone and instead the memory cards have taken those letter designations. The CD & DVD icons no longer appear and instead their letters have moved to I & J locations. if I rebbot they are back to normal...what is causing this?

Hi, In this case,check your cable connecting both drives.I will suspect that either your drive is having problem or the cable.Are they plug n play devices?

It sounds like one of the optical [CD] drives is developing problems. Try disconnecting one of them for a few days and several restarts to determine which one. HTH M2 If at first you don't succeed, you're about average.

the 6 cards = newer computer so i would have to ask are you using these when they switch drive letters? Wondering what you did wrong happens only when its too late

When you attach removable devices your Optical drives will automatically be pushed out to make room. The easy solution is to set your CD drives to letters that won't be effected by the greatest number of devices you may attach. If you change them to letters S and T then this will allow you to attach up to 15 devices (assuming you only have one hard drive/partion being the letter C:) without it ever effecting your optical drives letter assignments. To change the letters Right click My Computer, select Manage. Click on Disk Management under the Storage section. Then right click on your first CD ROM drive and select Change Drive letter and paths. Then do the same for the second. Hope this resolves your problem completely, Bryan

Thanks to everyone for the help. i think the situation is resolved with the last resonse with the drives being pushed out to make room as it happens when I attach my camera to the USB port Ray

Hi Ray, Glad Bryan's tip worked for you. I always out the first CD on R: That way even if I have a flock of cam cards etc, the CDs are 'out of the road'. M2 If at first you don't succeed, you're about average.
