There are some reports over at OCZ's forums of people losing data with their newer Sandforce-based drives (Vertex 2, Agility 2, etc). Basically what happens is the drive appears to be working fine but following a power cycle, you find that the drive has reverted back to an older copy of the stored data. Some of the more extreme cases have involved people reinstalling an OS on the drive only to find that, following a reboot, the old OS is back and the new one is gone. (Someone speculated that the drive might be shadowing its sector allocation map in onboard RAM but not always saving it to flash so when the drive resets, the old allocation map shows up).
Have any ATers seen this behavior?
