Windows 7: Hard Disk Partition Letter Missing in Windows 7 - Fix

64-bit Windows 10 Pro

Hello Ben, and welcome to Seven Forums.

From looking at your screenshots, the 931.51 GB HDD (Disk 1) doesn't have anything on it since it still has all of it's available space free.

Thank you for your attention to my problem. I too saw it showed noting on the disk, but I assure you that it is almost half full.

And even so it should let me add a drive letter should it not?

There appears to be some sort of issue with the file system on Disk 1 since it's not showing as either NTFS or FAT32.

You might see if you may be able to use the free Partition Wizard to either try and recovery Disk 1 or assign a drive letter to Disk 1.

If that fails, then you could use the link below to create a live Ubuntu disc to try and recover any files you wanted from Disk 1.

Afterwards, and there's nothing else you want on the drive, it looks like you may need to run the clean command on Disk 1 to completely wipe it clean, then format it give it a drive letter.

Hello Lionofct, and welcome to Seven Forums.

The Healthy (recovery partition) is your OEM factory recovery partition that allows you to be able to reinstall Windows 7 back to factory conditions. You would not want to add a drive letter or do anything else to this partition. Doing so, coud risk you no longer being able to use it to reinstall Windows 7 with.

Hope this helps,

i was using dell backup and a drive letter was not showing up in windows explorer so i changed the drive letter in disk management to something else, and it showed up in windows, and then changed it back to the origianl letter. so everything would work the way it was before, and it worked.
