C drive

Hans L · 14 Apr 2023

Hello!

In trying to set a drive letter for a HD in a dock, I managed instead to screw up my C drive (Win 10, x64, 22H2).

I am looking in MiniTools Partition Wizard and Disk 1 looks like this:

• R

FAT32) 100MB (Used ...)
• C:System(NTFS) 446.2 GB (Used 21 %)
• *: (NTFS) 892 MB (Used ...)

I know that "R:" is not what it used to be. "R:" was what I tried to assign do the HD in the dock. What should it be and how do I get it back?

The other two, I am not sure. Maybe they are okay!?

Grateful for some tips.

Can you post a screen shot from disk manager showing all details so we have more info

Press the Windows key +X and choose Disk Management. Make a screenshot including the bottom pane and attach it in your next post.
You cannot assign the drive letter C: it will be assigned if that Disk has Windows on it and you Boot the computer using that drive. Then it will automatically be C: If Disk 1 is a Windows drive, it looks like it is for a UEFI Bios
The first partition should be Hidden meaning, it has no drive letter in Windows EFI FAT32 which includes the boot files. The 2nd Partition Is the main part of the drive and should include Windows. The last partition should also be Hidden and be a Recovery Partition.

You cut off the Bottom Pane with the Disk #'s, ie ( Disk 0, Disk 1 etc that is more important then the Upper Pane

You assigned R: drive letter to the EFI system partition on your system disk. In order to restore the system disk back to normal simply remove the R: drive letter from the EFI system partition. Right click on it, select Change Drive Letters and Paths, make sure the R: drive letter is highlighted and click Remove.

If you want to do it command prompt, open a command prompt (with administrator privileges) and the commands will be:

Code:

diskpart
select vol r
remove
exit
exit

I do not think disk management allows you to select an EFI drive to remove a drive letter. If you want a gui solution, you need minitool partition wizard or similar ..

The diskpart commmand works fine of course.

Only disk 0 is relevant here, I believe.

I used the Command Prompt route, and it worked fine, of course. Thank you!!!

Thanks for saving me trying and trying and tryring with Disk Management. While I have MiniTools, I did it via Command Prompt, and is now a happy camper.
