for what matters, sometimes I managed to recover the disk by just dd'ing a zero block to the broken sectors using dd oseek=<nn> where nn is the sector number where read fails.
If you have a power failure during writing, you can actually screw up the low level format of the disk.
It sounds like the disk you dd'ed only had the high level format screwed up.
Julian got struck by lightning; perhaps he will now stick to disks with built-in lightning rods (e.g. not succeptible to this failure), e.g. SCSI.
