dd_rescue No additional sense

Hi all,

I'm trying to recover data off a dying hard disk (2.5" Hitachi 320GB
HDD). I was able to get the first two partitions without errors. The
third (system partition) started off OK but after doing about 44GB, I
get the following in logs:

This doesn't stop (waited for about 7hours) and the HDD activity light
(in external case connected via Firewire) is constantly red. This
doesn't seems to be something like an error reading data and hence it
doesn't continue reading from the device. Does anyone know what is
happening here?

Thanks,
KS
