I've suffered a very similar problem and posted to the list earlier, I
did, dd_resuce -l dd.log /dev/hdd5 ./hdd5 and winded up w/ this:
dd_rescue: (info): ipos:         0.0k, opos:         0.0k,
xferd:         0.0k
                   errs:      0, errxfer:         0.0k,
succxfer:         0.0k
             +curr.rate:        0kB/s, avg.rate:        0kB/s,
avg.load:  0.0%

it never changed, the file created hdd5 was 65536 bytes large.  The log
file was empty.  Am I doing something wrong?  Any info would be
appreciated.  Thanks in advance.
