Secondary Partition not accessible

Hey Community!

Going to keep it short:
- Installed a couple of Windows Updates
- Restarted PC
- Windows Updates were being configured
- PC restarted on it's own
- While finished restarting, more configuration were done
- Logged in

And then I couldn't see the partition D anymore, so I went to the Disk Manager and manually assigned a drive letter with success. But when I tried to access the partition I got the following error message: "You need to format the disk in drive D: before you can use it."

When clicking no I get the following: "D:\ is not accessible. The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted".

Is there anyway to solve this problem as I don't want to delete the partition or go for data recovery.

Thanks in advance and greetings!

  1. Is "D" a secondary physical HDD or is "D" a partition on the same HDD as "C"?

    Was one of the updates SP1? Also, what were you using "D" for (apps, storage, etc)?

    Please clarify.
  2. I shall clarify ;)

    D is a logical one, so same HDD as C.
    None of the updates included SP1.
    D was used for storage and also for My Documents (that new Library thingy in Windows 7)
  3. Run the Repair Environment (see link) and see if Windows will repair itself:

    Report back with results. If this fails, we'll get more aggressive. Good luck!
