Drive letter assignments for SD cards and usb pen drive

Subject: Did u try to assign another letter using the manage option of windows

changing letters in the first SD using the disk manager system.

I am working for an organisation deploying several hundred HP laptops,
These laptops have slots at the front for SD cards. When you pop a card in
at gets a drive letter e.g. E:
If you put a USB memory stick in first then the stick gets drive E: and then
if you put the sd card in the card tries to get drive F:
Unfortunately drive F: has already been assigned as a mapped network drive
via a logon script so the SD card is unuseable.
If you then take both cards out and even restart the laptop and then put the
SD card in again it still wants to be drive F:
the only way to reset it seems to be with disk management mmc. The users
don't have access to this as it is locked down by domain group policies plus
they are not local administrators.
Is there any way of ensuring that the sd card can trawl through and actually
find an available drive letter, not one alread mapped. In this situation
drive Z: is free but it doesn't try to find that.
Another option may be to get it to use letters A: or B: as the laptops have
no floppy drives. Is there a way of doing this?
Thanks in advance.

Use the high letters of the alphabet for mapped drives.
This will keep the low letters free for USB drives -
problem solved.

You could probably use drive letters A: and B: for your USB
devices, using mountvol.exe, but I consider this a messy alternative.

I agree with you about using the high letters for mapped drives,
unfortunately the company uses a lot of mapped drives and these have been
around for a number of years so changing them would be almost impossible as
there will be embedded links in applications and documents.
I may do some more investigation into mountvol.exe

Hi,
yes as mentioned in the original post I can change it with disk management
but the users are prevented from accessing this as they will end up changing
all sorts with dire consequences.
Thanks

This program would assign a drive letter to the USB memory stick. (I
haven't tried it.)

My card reader slots are already assigned drive letters.
If your card reader slots had drive letters, they could be relettered to not
use E so the USB memory stick could use E.

Hi,
I've had a quick look at mountvol.exe but I can't see how you can set drives
for the USB devices. is this something you have tried before?

Thanks

This command mounts my flash disk on drive B:

mountvol b: \\?\Volume{1b478140-6780-11da-a9c8-006067726afd}\
