I home built my computer, and it currently contains 3 hard rives. Two of the hard rives are raided, while the third hard rive contains all of my data. The OS is Windows 7 x64.
I had initiated a backup of my computer, and it started acting a little skittish. Before the backup completed, the computer froze and I had to restart. Upon restart, the third hard rive (the one with data, including photos) disappeared.
The hard rive is a Samsung HD103SJ. It shows up in both the bios and the Device Manager. In Disk Management, the drive is labeled as "Not Initialized."
The drive includes all of my data, and I would be devastated if I lost it. What could have caused the problem, and will I be able to restore the drive?
