November 18, 20169 yr I've just replace a drive and after doing a pre clear on it, which it passed, it's reporting 'current pending sector' is 1. Now as long as that stays at 1, the drive should be ok to use, correct? If that number increases, the drive is toast, correct? I don't necessarily plan on putting the drive back in the array or using it for anything too important, but I am just asking you lot what you would do with the drive?

A pending sector is a sector that the drive thinks might be bad. On the next write to that sector, the drive will either determine that its ok, or it will reallocate that sector. You really want pending sectors to be zero, and the # of reallocated sectors to be stable at whatever # you are comfortable with. My opinion is that if the drive is brand new, I'd return it.

November 18, 20169 yr Author Ok thanks, I'll do another pre clear and see where that gets me with this drive.
November 18, 20169 yr If that current pending sector of one appeared *after* successfully Preclearing the drive, that's not a good sign! I would Preclear it several more times, and expect perfection. If more bad sectors turn up, then you can't trust the drive, it's probably failing.
