I used smartctl (part of /usr/ports/sysutils/smartmontools) to run a
diagnostic on the disk, and while it does acknowledge an error, it
seems to think the drive is okay. However, given that all of my files
are still missing, I'm still a bit skeptical.
Error 1 occurred at disk power-on lifetime: 2920 hours (121 days + 16 hours)
When the command that caused the error occurred, the device was
active or idle.
After command completion occurred, registers were:
ER ST SC SN CL CH DH
-- -- -- -- -- -- --
84 51 0f b0 bc 5d 4f Error: ICRC, ABRT 15 sectors at LBA =
0x0f5dbcb0 = 257801392
Commands leading to the command that caused the error were:
CR FR SC SN CL CH DH DC Powered_Up_Time Command/Feature_Name
