This is a Ubuntu issue, really, Ubuntu has implemented new stuff , device-kit (ata)
among others. This has resulted in Smart error messages in user space, where it
has caused many (users) to wonder wtf.
It is still the same info, Smart enabled drives, you probably didn't test with
smartctl very often, at least I didn't.
AFAIKT, if ' Reallocated_Sector_C, & ' Offline_Uncorrectable' equal zero the drive
firmware is still doing its job of remapping bad blocks.
Lots of info on google, dating way back, on smartmon tools.
