Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Another datapoint. I have a hard disk whose filesystems are *not* mounted
at start-up, but after a corruption issue, the disk's state causes a lock-up
requiring a hardware reset and a second start-up (not helpful if this was a
remote machine).
On the second (successful) start-up I saw these messages:
$ dmesg|grep sdc
[ 4.934246] sd 2:0:1:0: [sdc] 66055248 512-byte logical blocks: (33.8 GB/31.4 GiB)

This means: your hard drive has an HPA
<https://en.wikipedia.org/wiki/Host_Protected_Area> configured, but you
actually use that area under Linux. Linux automatically enables access
to the HPA when it detects this. This was implemented in 2.6.34 and
backported to squeeze; you just didn't notice the messages before.
Ben.
