My RAID 1 system has 2 hot-plug removable disks, so you have 3 disks and rotate all 3 of them through the device periodically.

That is still NOT a reliable or proper backup solution. You system suffers a serious performance bottleneck when you swap drives and it has to rebuild. Also if you suffer a drive failure during rebuild you lose data that happened after you pulled the drive. This system would not be good for daily backups.

I have daily incremental backups for 7 days and maintain 2 months of backups. Something drive swapping does not allow for easily.

Forgot to add, RAID controllers FAIL sometimes they like to corrupt the data before failure too. I would NEVER use RAID in any fashion for backups. I have seen too many dumb sysadmins rely on RAID for backups only to be burned and without a job!

Watch the next time that you are plugging and unplugging your drives because even though 99% of the time you don't have to tell Windows that you want to unplug your drive, if you unplug it at the right moment the drive will become corrupt. I had this happen with my ipod, I unplugged it too quickly and the whole rockbox section became corrupted. Make sure you are safely removing it from windows.

Could have been caused by the "Windows delayed write error".
I think the Master File Table gets corrupted for a variety of reasons and Windows stops recognising your disk.

You should be able to recover all your data by performing a format and using a data recovery program. Good luck
