That said, I highly recommend copying the disk showing read errors onto another disk, keeping the log of sectors replaced by zeros. Then performing a file by file backup from the degraded array, using the copy instead of the troubled drive.
I believe there is also a way of injecting a hardware error onto a drive. Unless you can take a backup of the backup :-) I wouldn't recommend it at the moment, but there's some ATA command or whatever that tells the drive to flag a sector as bad, and return a read error until it's over-written.
Obviously, doing that on the sectors that weren't rescued, and then doing a scrub, is going to recover your data if it's both possible and done right :-)
