Realloacted Sector Count = INVISIBLE bad sectors that have been swapped with reserve sectors.
Crystaldiskinfo current pending sector count how to#
Sadly, few people know how to interpret the SMART data, and programs that try to interpret for the user do a poor job at it. It's so sad that SMART is so poorly understood I think SMART tells alot about the drive and is the best drive diagnostic available. more WD Green drives, the only long-term solution is probably to just call all the drives a loss and replace them with something else. And really, since WD will only replace dead WD Green drives with. Since this box is just a backup for another (which is itself running in RAID-Z, so single-disk redundancy), I'm not too worried about having to take it down later for another drive failure. Should I RMA the drive anyway, or is it, in all likelihood, just fine? I'd rather not have to RMA any more drives than necessary, since of the 7 original drives (all bought from NewEgg in a single batch, ~6 months ago) I'm now up to at least 4 RMAed (more if the final two drives scanning now report failures). Now, 3 totally failed the diagnostics for an unrelated reason, but for the 1 that didn't, the WD Diagnostic tool seems perfectly happy with that sector count it reports that the drive passes all tests. Minor issue: at least 4 of the 6 drives give me a SMART result of Reallocated Sector Count: 200.
I mean, why not check and see how they're doing? Especially now that I have a spare machine with internal SATA bays, so a full surface scan takes 6hrs rather than 25hrs like it did with the USB2 dock. There's no data on the array (it's about to become the backup of another FreeNAS box), and I decided to run all 6 WD Green 2TB EADS drives through the WD Data Lifeguard Diagnostics suite. I recently brought down my first FreeNAS box to replace a disk it was reporting as bad.
