I have a very strange problem. I just purchased a new Western Digital My Passport 2 TB USB drive. I have formatted the drive in Fat32 (Required for my device).
- When I connect the drive the Disk Management application sees the drive but no Driver letter is assigned.
- Disk Management reports the drive as a Healthy Active Primary partition.
- I right click on the drive and assign a drive letter which works as expected. I can now access the drive via file explorer and read and write files.
- If I disconnect the drive, the drive letter remains visible in explorer and changes to "Local Disk"
- If I reconnect the drive once again a drive letter is not assigned (original drive letter remains listed as "Local Disk" and is inaccessible).
- I can reassign another drive letter as I did in step 3 above and the issue repeats over and over. Of course each time I have less and less drive letters available to me since the assigned letters never release.
- In order to reclaim the drive letters I have to reboot (after disabling fast startup in power options, so hardware is re-initialized during reboot). Once reboot is complete all the "Local Disks" created during this process are removed and the drive letters are once again available for assignment.
- This process repeats over and over
- I have another 4TB Western Digital My Passport Ultra drive (formatted in Fat32), that does NOT exhibit this behavior. It works normally
- The problematic drive works fine when connecting to my Mac.
- All other USB drives and sticks I own do NOT exhibit this behavior.
- I confirmed in Diskpart that Automatic mounting of new volumes is enable
- I contacted Western Digital and after working with them for a while their assessment was since the drive works when a drive letter is manually assigned and works fine in a Mac the drive is fine, they suspect this is an issue with Windows 10.
- As a test I also reformatted the drive using NTFS and the issue still happens
Any assistance is appreciated
