Just sharing my personal experience (own hardware and that of others),
which is that once you prune out the hard disk failures caused by power
outage, there are not much left. And in (almost) all of the power outage
caused failures you can re-use the hard disk perfectly after a low level
format. And that is not due to bad sector relocation, but simply because
the CRC errors are cleared.

Problems caused by the interruption of a write operation by the disk are
not distinguishable from 'real' hardware failures by the OS. The hard
disk's firmware treats the sector where this interruption occurred as a
bad sector, and reports it like that to the OS. So you also get a lot of
messages in /var/log/messages. This phenomenon occurs on the harddisk
itself, past the operating system, filesystem and ide controller.

However, you should be able to get some raw data out of it using dd (or
ddrescue), as not all sectors are marked as 'bad'. That makes it
slightly less bad as a total hard disk crash.

PS: another tip: The sysadmins at work once told me that their
experience is that harddisks tend to fail when they are shut down. What
they dread the most is having to power down a server, even cleanly.
