SATA Drives go from 400GB to 128GB upon Restarting Backup Worstation
Posted on 2009-02-13
I have a Athena Power BP-SAC2131B HD Backplane (3 Bay) installed into a XP Pro SP2 Workstation that I use to capture our servers backup Acronis images nightly. Recently, after restarting one of my WD400YR SATA drives became unreadable. When I attempted to access the drive, it asked me if I wanted to format the drive. Using Disk Management, the drive now shows that it's 128GB and is unformatted. There is another 500GB WD SATA drive also in the Athena Backplane that did retain it's integrity after restarting where the other didn't. Since I don't have endless amounts of hard drives lying around, I'm going to safely eject all drives withing the Athena Power Backplace before restarting going forward.
Can anyone tell me how this problem can be avoided, or why it's happening all of a sudden?
Also, is there any way to turn the WD400YR back into a 400GB drive?
