In addition to Reco's advice, some HDDs have special programming in 
their firmware, which basically prevents the drive from falling into 
recovery loop until system is rebooted once they encounter a bad block.
It is called SCT Error Recovery Control [1] and could be checked using 
"smartctl -l scterc /dev/sdX".
HDD manufacturers often name their products with this feature as "Pro", 
"NAS edition", "RAID edition", etc, but it is always necessary to check 
full specifications for the product in official datasheet.
