    No drive-letter assign to USB - how to fix?


    Greetings.
    A while ago one of my USB HDDs did not get a drive-letter when I connected it. I have to go to controlpanel, disk-management to assign a letter manually.
    Now it has spread to all of my USB-drives and also to my lonely eSATA HDD.

    How do I fix this, so drives again automatic will be assigned to a free drive-letter? (example to h:\)

    Run diskpart from an elevated command prompt, type automount and enter.

    No, that was not enough. It wrote Automatic mounting of new devices disabled. Tried again, and same result. Then I tried HELP AUTOMOUNT, and found the solution. I have to write "automount enabled".
    This worked. Thank you for pointing me in the right direction :)

    Yep, I missed it by a whisker in a hurry to go to bed.

    Typing automount will show you the status. In your case it was disabled and the status was shown.

    Once the status is known typiing automount enable enables it.

    Thanks for your feedback. You did a good job catching on the suggestion.

    A new problem occured. Now the hidden drive (100MB) as Windows 7 uses for UEFI-boot, is getting a drive-letter .

    How do I hide this drive from the drive-letters, but keep the automount for attached USB-HDDs and USB-sticks?

    As windows was new-installed, I'm pretty sure, that this small "boot"drive did NOT have a drive-letter, I want that to be true again, if possible. But I don't know how

    Go into disk management and remove the letter.

    Yes, but after next reboot, it got a letter again. I want drive-letter to stay away from this special drive.
