Fixed Drive Letter for USB Drive
I have a little USB memory card that I use to take files between home and work. I want to write a batch file to pull files from the card and load them onto the computer. The problem is, if I boot the computer without the card in place, it gets assigned the L: drive but if I boot it with the card in place, it gets assigned the I: drive. I know how to force a hard disk or zip drive to have a fixed drive letter (my zip drive is Z but it does not work for a USB card. Any suggestions on how to force the USB card to have a fixed drive letter? I would really like to use something not in the regular sequence like S:

Re: Fixed Drive Letter for USB Drive
"An USB pen drive is drive and media in one. Therefore the drive letter comes and goes with it. In contrast a card reader stays attached and only the card is plugged and unplugged, so the drive letters stay.
Because it's drive and media in one, each time you plug a pen drive for the first time the Windows plug'n play starts up a assigns the first availlable drive letter. When the USB has no USB serial then this happens again if it's atteched to a differenct USB port."
To get rid of the 'first free letter assignment' I wrote the USB Drive Letter Manager which works under Windows 2000 and XP."
So it would seem that getting a card reader and leaving it attached is one solution. Or you could try the utility USBDLM this person wrote.
"USBDLM is a Windows service that gives control over Window's drive letter assingment for USB drives. Running as service makes it independent of the logged on user's previleges, so there is no need to give the users the previlege to change drive letters.
It automatically solves conficts between USB drives and network or subst drives of the currently logged on user.
Furthermore you can define new default letters for USB drives and much more."
