I added an old HDD as a slave to my PC which runs on VISTA ..
The partitions on this HDD showed up.
I was accessing the partitions to check what it contains. Then my AVG anti-virus found some virus andmoved it to vault.
I then formatted one of the partitions. During the process, i saw one additonal drive without any space information or name. i double clicked it to find out what it is. The system restarted and now i cant the partitions of the slave HDD anymore in My COmputer as well as Device Manager.
It is detected in the BIOS though.

Please help !

How do they look in Disk Management?

Right-click Computer > Manage > Disk Management.
