since messing about with all this dual booting stuff i've realised that the bios order of the drives and what it considers the boot order doesn't necessarily match what software/boot loaders and operating systems consider to be the drive order - that's where the accidental deletions occur (but probably not if you can give labels to things).
Yeah, PCs are extremely
crap in this regard - if you have mixed SATA and PATA drives (or RAID, to make things even worse), things can get extremely messy. The retarded standard partition table layout doesn't help either. Mess, mess, mess.
Did you by any chance have any of your drives set up as "dynamic disks" in windows, instead of using the old-style partition format?
Can't really think of a good reason why your disk would be nuked, though... sounds weird. Btw, never do "in place" recovery if you can avoid it, the best solution is always to restore files to another partition. The best recovery software I've found so far has been GetDataBack
. It's slow, but it's been able to recovery pretty well.
Thanks DOYC you had MirrorFolder running, I hope it means you didn't lose any data after all.
