Four SAMSUNG SpinPoint T166 series, HD501LJ and more than 4 years in a 8-core server, here are the raw error rates:

Fail?

Update: Running “dd if=/dev/zero, …” on the fourth actually bumped the reallocated sector count even further:

5 Reallocated_Sector_Ct 0×0033 098 098 010 21
196 Reallocated_Event_Count 0×0032 098 098 000 21

Selectively overwriting defect sectors?

dd if=/dev/zero of=/dev/sdX bs=512 count=1 seek=Y

Where X is the storage device, and Y the LBA sector address, …

Update 2: Some manual sector write, to reallocate loops later:

# 1 Extended offline Completed: read failure 30% 34103 663074301
# 2 Extended offline Completed: read failure 30% 34101 663073326
# 3 Extended offline Completed: read failure 30% 34084 664843895
# 4 Extended offline Completed: read failure 30% 34080 561288851
# 6 Short offline Completed: read failure 90% 34007 409641893
# 7 Extended offline Completed: read failure 90% 32227 791207080
# 8 Short offline Completed: read failure 90% 32227 791207080

I should just throw away this piece of s**t, right?
