But, that's not even the main issue (although I suspect the excessive load cycles contribute to the drive problems with WD Green Models).  Sector Read errors inside of a year of use is the issue I've had with them, even though SMART data showed the firmware hadn't reallocated any bad sectors to spares (leaving them in a "pending reallocation" state instead.

IMO, that's horrible behavior, since users may not realize their disk drive is what's causing their issues until they lose important data.

SMART Data from another one (I've got some sitting on a shelf that I don't trust for use anymore) and slapped another one into a docking station to look at SMART data from it.

No sectors were reallocated to spares (same behavior I've seen with the other WD drives that I've had issues with).  I noticed the problems with this one when a backup failed with sector read errors (so I ended up using ddrescue to try and work around the bad sectors to get a good disk image backup of it (and they were "hard" read errors, too).

This one did make it to a bit over a year (close to 16 months from what I can see of power on hours).    But, that's still absurd, especially since the drive firmware didn't even try to remap sectors it must have known had issues, as it has 30 sectors pending reallocation from what the current SMART data shows.

Load Cycle count (over 400,000) had also exceeded the drive's rated specifications of 300,000 (unlike the last one I posted SMART data from, which was still within specs), which may have contributed to problems.
