[SOLVED] Help! A device which does not exist was specified.

[Kampfzentrum]

I'm hoping someone here can help me. I just recently purchased an external drive, so I plug it in and:

E:\ is not accessible.

A device which does not exist was specified, Drive is not accessible

I've searched the Internet and most people start their resolutions by right-clicking on the drive in My PC > Properties, etc. BUT... The drive in both Explorer and Disk Management only pops up for a second before disappearing the creating another message above. If I left the drive alone (on) it would create an unlimited amount of error at about one every 10 seconds. It's as if Windows is assigning the drive the default letter E: but it is also not allowing it. Just to inform anyone, I currently have four drives on my PC:

1. C: drive, my SSD main boot/program drive
2. X: drive, my personal data drive
3. Y: drive, the drive I download to and store random data
4. Z: drive, my archive drive

I do have an optical CD drive that is assigned D:

So what is going on? Thanks for the help for anyone in advanced.

The command to remove a drive letter - which shouldn't be needed, but hey, Win10, there are still some bugs - is mountvol <drive> /D, so for you it would be mountvol S: /D and mountvol T: /D. You can also try mountvol /R, which should remove all drive letter assignments for which there is no currently mounted drive. You can also try using /P in place of /D, but it's intended to be used while the volume is actually present.

You can also use the remove command in diskpart to remove drive letter assignments. You mentioned using mountvol to try re-assigning the drive letters but didn't mention trying to remove them. I'm pretty sure it just calls the same APIs as mountvol, actually.

All of these commands will need to be run as Administrator, naturally.

Just so you know, if you boot off a recovery drive, windows might call that X as its the letter it normally assigns to when its booting off a ram drive
