I've been building, maintaining, using computers for a long time and have never seen this. Gigabyte MB with on-board BIOS based RAID, set up as RAID 0. Running Windows 7 Professional 32-bit.
Sometime over the the last few months one drive failed. I had not had time to fix it, so just left the system running on the other drive (still with RAID turned on).
This computer is in an office I don't use too often, last time was a couple of weeks ago. The computer is left on all the time.
I go there yesterday and the computer had reverted back to a state from Feb 18th -- four months ago! Every single file, every update is gone from Feb 18th to June 26th. It is literally like the computer time-traveled back to Feb 18th.
My theory is that at some point over the last two weeks the failed drive came back and the RAID re-mirrored from that drive. The drive appears to still be dead so maybe it was intermittent. Or maybe I'm totally wrong about this and it's something else.
Has anyone ever heard of or seen anything like this? I'm the only user of this computer, and other than me taking manual disk-image backups (which thankfully I have!) -- there are not automated tasks running that would do anything remotely like this.
