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
