Maintenance Mode Fixdisk can't unmount mnt/hd2

Once the fix-disk run is complete, you can force the sector to be "repaired" (ie, relocated and probably zeroed) at the maintenance mode command line:
umount -l /dev/sda2
hdparm --write-sector 1269938081 --yes-i-know-what-i-am-doing /dev/sda
This is equivalent to the command that fix-disk would have used if you'd hit Y, especially if you actually include the disk device name.

I've hit the same problem, having noticed my HDR3 running unauthorised deletes:


(sorry about the screenshot, webshell copy doesn't seem to play well with Linux Mint)

Yes, I am running the "latest" firmware (the beta), no I don't have any other drives plugged in (made redundant by virtual-disk2).

Reading through the thread I find "have you turned it off and on again" has cleared this in one post... and relax.
