regarding earlier post with do not reply request.
There's loads of HDDs advertised as "for CCTV, like a PC disk"
Is there some difference between HDDs for video recording and regular
PC HDDs ?

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.
