Windows 7 hard drive unallocated after update

Last response: in Storage

I have a secondary SATA HDD that suddenly became unallocated space after installing the most recent Windows 7 update. Before the update, this space was partitioned, formatted and allocated.

After the updates were applied and the system restarted I received a notification that windows found a new SATA device and installed the drivers. The drive no longer appears in My Computer. When I go into Disk Management there's no option to create a new simple volume or allocate the space (I've done this before...). I tried rolling back to the previous update, but that didn't help. Any ideas?

Would you mind telling us what update you installed?

I wish I had paid more attention. I've been letting Windows download and install them automatically.

You can go to the website, and view your download history.

Try using the restore points to roll back before the updates. See if that brings back your drive. If it does, manually install those updates 1 at a time. If the updates caused it, then you'll know which one it was. Though, none of them look like they should've affected your drive.

I tried rolling back to other restore points. That didn't work. I"m at a loss...

I checked the cables and reseated the HDD. After the second try it started working. Thanks for your help.
