Hi Michael
The difference on an active and an inactive partition on a hard drive is only a few bits on the platter.
All hdd's are expected to make such an error, on very rare occasions. I think the common number is about 1 time in 10^15 read attempts, so it might just have been a freak accident.
But I suggest that you run a full diagnostic with surface scan on that particular drive, as it might also be a bad disk.
If you happen to find any other errors in the scan, I suggest you get a replacement from the dealer, before you loose any important data. :)
Thanks for the suggestions jakob
I've run full diagnostics on the HDD. No errors.
If it had happened just the once I would agree with you but as it kept happening I believe it was intentional. I have backed up all the data and am reinstalling the SOE.
Thanks for the advice
