I suggest you try this:
hdparm --read-sector 1953519935 /dev/sdb
If that succeeds, then the sector is good at the drive. But *If* it fails, then you could check the syslog to ensure that it didn't fail for some weird reason, and then *fix* it:
hdparm --write-sector 1953519935 /dev/sdb
This is very different from how 'dd' does writes.
Cheers
