The counts look to be correct.

I mean 05 - Reallocated Sectors Count raw value is correct. So is
Reallocation Event Count, Current Pending Sector Count, Uncorrectable
Sector Count, UltraDMA CRC Error Count. Some other values are
definitely not standard but the important counts are correct.

Here is an example that tells me the drive had 71 reallocated sectors.
