i have several USB thumb drives by same maker. trying to find a way to when i plug in drive each has a different drive letter.

    Question

  • If I plug in ONLY one of any of the usb 2.0 or 3.0 thumb drives WORKS good. IF I PLUG IN A SECOND DRIVE, BOTH DRIVES TRY TO BE THE "SAME DRIVE LETTER" !!!

    drives are "Lexar" brand because they are the ONLY drives I have found that the connector is exposed to dust and other crud.

    closest I came to a fix (in Microsoft answer site) was to change the "registry" 

    THE change seemed to be based on when drive pluged in, look at drive letter,

    then in registry change the driver from say "F" (that popped up 'automatically') to say "P"  THEN seems anytime that driver was running and being used by one usb thumb drive computer would think that drive was drive "P".

    Great if ALL my drives use different drivers.

    A problem for 5 drives, if the 5 all use the same driver.

    Used in this case for a win7 Ultimate 64 bit, Office 2013 64 bit

  • Hi PuzzleByWord,

    I can not believe it, and have not experienced it like BOTH DRIVES TRY TO BE THE "SAME DRIVE LETTER.

    Let me ask... How many "drive letters" are left in your compute/Windows Explorer?
    As you know drive letters are between A to Z, i.e. maximum 26 drives.

    If you would connect more than 26 drives, your computer(OS) must be confused 

     #  I suppose that a drive letter of a removable device(especially USB flash memory) depends on a USB port connected with the device, and that Windows remember the relation between a device and an USB port.

  • Ashidacchi,

    Based on your response maybe you have a answer to this.

    even if I limit number of drives to under 4 external drives, and use different ports on computer and a 3.0 usb hub in one port I have same problem.

    Need to have each drive plugged in assigned a fixed drive letter.  NOT based on what order drive is plugged in to laptop.

    Have lots of code that uses "Path" as in G:\folder\subfolder\filename  in UserForms     AND need to move files referenced that way to usb drive(s).

    That won't work with the USB drive IF the drive letter depends on order plugged in to be assigned a available letter. at least as far I can find samples or figure out.

    any workable ideas will be greatly appreciated.

    p.s. sorry sometimes I do not know the correct term to use. I do the best I can to use the right terms in the right context. I am learning as fast as I can.

  • You can change the drive letter for one or the other in Disk Management snap-in. I'd ask them more over here.
