I agree that is probably the issue.
You could first try downloading and updating the FIRMWARE for that drive. It may overwrite the corrupted data on the drive.
Also, is it under WARRANTY? If so, attempt to exchange it (most warranties are a year and require printed or electronic proof of purchase. I even contacted NCIX to get my transaction number to solve a Warranty with one company.)
Here is the link to the firmware update. Download and run this program:http://esupport.sony.com/CA/perl/swu-download.pl?mdl=VGNFW275D&upd_id=5326&os_id=28
(says "Vista" but should work on all Windows version)
**Let me know if this helped!
