I Have an internal HDD drive with multiple partitions & one keeps loosing it's letter? It keeps disappearing and I have to re-assign it and reboot.
This has been happening for a few versions but I'm getting fed up of it now.
Anyone have any ideas as to how I can stop this?
Thank you.
Windows 10 Version 20H2 (OSBuild 19042.985)
Witch drive and witch partition keeps losing the assigned letter?
PS: Sorry, just seen it is Z:
In a command prompt with admin privileges try:
Note the above commands must be started when Z: drive is present.Code:diskpart select vol z remove automount scrub assign letter=z exit exit
Hi,
I have previously scrubbed the automount points for this drive, but the problem persisted.
I have done it again so I will let you know, soon.

Hi,
Booted up ok 3 times, but it looses the drive letter whilst sat doing nothing, screen saver active.
Any more suggestions?

Hi @Lottiemansion
Try increasing/decreasing the size of the last partition Z: without losing any data. Then check whether you lose your drive letter.
Reason: It is quite possible that the start sector of the partition where the Volume Boot Record resides is weak. If that is what is causing the frequent disappearing , shifting the start sector even by one sector may resolve the problem.
Note: You may do well to do a Surface Test of that HDD.
Hi and thank you for contributing .
I have resized & moved the drive as you can see. Lets hope this helps!
All good on checking disk.

Glad to know that the issue got resolved by shifting the Volume Boot Record at the start sector of the partition ( by resizing the partitions). Nothing to be alarmed at this point but periodically do run a surface test and check. For peace of mind, you may also check the health of the HDD with the Limited Trial/Free version of Hard Disk Sentinel Download Hard Disk Sentinel
