Windows 10: partition letter problem

Windows 10 Pro V 21H1 Build 19043.1165For some reason, File Explorer will not display volumes with letters I and J. I can assign them with Disk Mgt. and browse them from there, or manually put the drive letter in Explorer, but it will not show up in explorer. Diskpart sees it correctly also. If I change the Drive letter to K it shows up fine. C through H is already taken up. In the past, I had an external esata enclosure with two disks in it that I think were assigned I and J. They are no longer connected. Is Windows remembering them some how? If so, how do I un-remember them?Thanks,

:)

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Drive letter on OEM Partition

Microsoft is aware that previously-hidden partitions are improperly being assigned drive letters after installing the April 2018 Update. As a result, they now appear in Disk Management and File Explorer. These partitions are typically recovery partitions
used by the Windows Recovery Environment or by the Original Equipment Manufacturer. It is not recommended that you attempt to delete or reformat these partitions as this may have adverse effects on your ability to recover Windows. Microsoft is currently working
to address the issue in a future Windows Update, and we’ll update this thread when a solution becomes available.

(Update 5/14/18: The solution that will soon be released via Windows Update will only prevent this issue from occurring for devices that install the April 2018 Update after the solution is released. If you've already installed the April 2018 Update and are
experiencing this issue, you'll need to follow the steps below if you want to hide these partitions.)

Although you can safely ignore these partitions, if you prefer do away with the low disk space warnings and hide the partitions so they no longer appear in File Explorer, you can do so by manually removing the partition’s assigned drive letter. To do this:

1. Select the Start button, type cmd and then right-click Command Prompt in the search results and select Run as administrator.

2. In the Administrator: Command Prompt window, type diskpart and press Enter.

3. Type list volume and press Enter.

4. Make note of the volume number for the drive letter you want to remove. For example, if the drive letter you want to remove is Drive “G”, note the volume number for Drive G.

5. Type the following command, and press Enter.

select volume <volume number>

When typing this command, in place of <volume number>, substitute the volume number you made note of in Step 4. In the example above, if the volume number for drive G is 5, you would type: select volume 5

6. Type the following command and press Enter.

remove letter=<drive letter>

When typing this command, in place of <drive letter>, substitute the drive letter you want to remove. In this example, you would type: remove letter=G

7. Close the Command Prompt window.
