Current pending sector count 242

The current pending sector count is not worse than reallocated sector count. Basically it is the same thing - except that current pending sectors is for disk reads, and reallocated sectors is for disk writes. In both cases, I/O to that sector fails. On a read failure, the drive doesn't bother reallocating, since it doesn't know what data to write into the reallocated sector anyway. Later on, if the NAS tries to write to the same sector, if that fails [which is almost certainly will) it will be reallocated. You could a long generic test with WDC Lifeguard - it may not be reaching the problem area in the short test. The NAS test is only the Smart self-test built into the drive firmware btw. But if I had a drive with 242 current pending sectors, I would certainly take it out of service. Yes, it could theoretically remain stable at 242, but in my experience it is far more likely to quickly get worse.

You are right, I ran the WDC lifeguard long genertic test as you suggested and it FAILED due to "too many errors. " even though it passed the seagate long generic test and the short test with lifeguard.

I think I will attempt to get the drive replaced. Thank you for the great advice!!!
