Losing Just *some* CD/DVD Drive Letter Assignments every boot

    I used the Disk Management tool to assign specific drive letters to each non-hard drive on my system (M for my external firewire MyBook drive, R and S for my two CD/DVD drives, P for a virtual CD/DVD drive, U for the memory card reader in my HP All-In-One, and X for my USB flash drive when it's plugged in).

    But now when I reboot, I *always* lose the drive letter assignment of just *some* of my CD/DVD drives: one actual CD/DVD drive reverts from "R" to "G", and one virtual CD/DVD drive reverts from "P" to "H". G & H are the first drive letters after my internal hard drives/partitions. None of the others seem to be touched! That actual CD/DVD drive is installed as Master on the Secondary IDE port. (The other real drive is Master on the Primary, and its drive letter never changes).

    This started happening only recently (in the last few days). Before then, I did not have this problem.

    Naturally, I ran extensive anti-virus and anti-malware tools against everything on every drive. (That includes Avira Classic Free AV and G Data AV (with both the Kaspersy and the BitDefender engines), A-Squared anti-malware and Spyboy S&D), all with the latest definitions.) But nothing was found. I also run with an absolute minimum of startups; out of the 30 or so that would run if I let them, I only allow about 6 (but that hasn't changed recently).

    There hasn't been any significant changes to my system; only a couple of extremely routine software installs. I tried uninstalling them again, but it made no difference.

    Any ideas about what's going on and how to fix it?

    Surely someone has an idea or suggestion, don't they?

    If these are removable drives and are removed when they are plugged back in they will be assigned new drive letter designations, as far as I know you have to leave them plugged into the exact same posts all of the time and if you want to remove them I would try shutting down the computer and then remove them and when you go to turn the computer back in plug the devices back into the same port that they were in the last time after shut-down.
