The tool is designed specifically to detect faults that other tools don't detect so the fact that both the manufacturer's tool (usually they just run SMART test), smartmontools (just a SMART test again) and badblocks (really simple test able to detect only the most obvious corruption) find no problems with the drive.

If you could attach the '--log' file and '--outfile' from '--quick' run in single user mode (or `--exclusive` run) I should be able to say if this isn't a false positive (not out of realm of possibility).

The other tool that may detect the same errors as hdck does is MHDD.
