    Question Windows 7, Change USB flash drive letter not working

    When I plug in my Kingston USB flash drive, and I go through the process of changing it's drive letter, I get the error message "The parameter is incorrect".

    The letter is not in use.

    My Windows XP doesn't have a problem with this.

    Is it the flash drive the problem?

    Can anyone tell me why I would be getting this error?

    Thanks.

    The USB device is generally assigned a drive letter when plugged in, and loose that designation when unplugged. Usually the assigned drive letter is the next available letter.

    I know that, but I have other USB drives and flash drives that I have changed the drive letters on.

    I don't know why I am getting that particular error message from Windows 7.

    Thanks.

    Actually, the USB drive letter tends to stay until the device driver is uninstalled. My scheduled Acronis backups wouldn't work if I didn't get the same drive letter every time I plug and unplug my backup external USB drive. Perhaps you are trying to assign a drive letter that is in use by a previously plugged in USB drive? Does it work if you use a different drive letter?

    That's a good idea. I think I'll try it.

    I am always trying to change it to a drive letter that I use on my other computers. My other computers at work and at home always see it as drive Z:, but on my Windows 7 machine, it won't change to drive Z:. I'll try to change it to something else to see if that works.

    Thanks.
