Guest Cameramonkey Posted October 2, 2008 Posted October 2, 2008 Anyone know why after 16 years and (6 major versions), windows STILL cant tell that a drive has been mapped so that it doesnt re-use a drive letter for things like card readers? Have I been missing something all these years? I am getting tired of having to manually configure a card reader in drive manager to not use F: because a network share is already mapped to that letter. anyone? (or has this been fixed in Vista and I havent run across it yet?) And yes, I know that one fix is to map network drives from the bottom up, but thats not really a fix. Thats just avoiding the problem.

Maybe Microsoft should make the letters below L: unavailable to mapped shares in order to drive this point home and stop the moaning and bitching.

A reversal of this strategy would cause the opposite problem with USB drive letters. Have a look at USBDLM: http://www.uwe-sieber.de/usbdlm_e.html.
Guest Cameramonkey Posted October 2, 2008 Posted October 2, 2008 Re: physical drive letters stepping on mapped drives. Why? Monitor: mapping from the bottom up doesnt fix the problem, it works around it. Its the equivalent to : "doctor, it hurts when i do THIS." "then dont do that.". Pegasus: then how do you explain the behavior of a system that has been up for days/weeks and you plug in a new device? the new device is stepping on a drive that has been in place the entire time and what technically there first. So its not always about processing physical drive letters first.

No it won't! Cameramonkey is right, if you plug in a USB drive, it will be assigned the first letter after the hard and optical drives, even if a network share is mapped there. MS got this screwed up and they've never fixed it in XP.

Remove your J: drive and then shutdown the XP. Reboot the XP with the J: drive connected. It should be detected before the mappings occur and could get I: instead.

Remove your J: drive and then shutdown the XP. Reboot the XP with the J: drive connected. It should be detected before the mappings occur and could get I: instead. ========== Yes, I know it will, because USB drive letter assignments happen before network assignments. This is what I said before. Tim Slattery claimed something quite different (and perhaps the OP too): "If you plug in a USB drive, it will be assigned the first letter after the hard and optical drives, even if a network share is mapped there."

My experience seems to be different than yours. I have a hard drive partitioned into C: and D: and an optical drive that is E:. I also have a number of mapped network drives. I've had to leave F: open, because if I map a network share to F: it becomes unusable when I plug a USB drive in. The USB drive gets the F: letter, and the mapped network share disappears until I unplug the USB drive.

What the SP3 did not fix is this scenario: Letters C: + D: used for local drives, E: for an USB drive. Remove the USB drive, create a network drive at E: and reattach the the USB drive again. XP with SP3 will assign E: anyway, the USB drive is 'hidden'. This is fixed in Vista. Uwe

The USB drive will, in fact, re-appear as soon as the network drive is disconnected (which is, of course, pretty useless). Using the high letters of the alphabet for networked drives will avoid the issue.
