This could affect anyone with an ARM computer running *nix and a low-power USB hard drive. Here's what my drive looked like when I realized I needed to check it. It's been spun up for about half a year:
$ MY_DRIVE_OPTS="-d sat /dev/sda"
$ sudo smartctl -a $MY_DRIVE_OPTS | grep Load_Cycle_Count
193 Load_Cycle_Count 0x0032 109 109 000 Old_age Always - 273664
For those not familiar with smartctl, some explanation may be needed.
