I have 4 - WD Ultrastar DC HC530 14TB SATA 6Gb/s
I used “S.M.A.R.T. Data” from my EX4100 Nas. Im trying to figure out what dives are bad. Im stumped on line 187 Reported_Uncorrect. is it 1 or 100 that is good. When I looked up on google, AI seems to tell me conflicting answers. I’m thinking the order of the drive Best to worst are 2, 1, 4, 3.
I would appreciate any help you can give. Thank you
Sincerely, John
Usually a bad block or so is par for the course with hard disks.
I use Seatools which can zero wipe all disks without concern for brand or technology. WD’s software seems inadequate as it cannot recognize many WD disks.
I find disks can be refurbished by zero wiping then which allows the onboard logic to allocate or clean up blocks that are marginal. Hard disks, SSD are all fixable with Seatools.
100 is good, 36 is bad, and 1 is very bad.
I find at zero wiping counts often reset
Thank you so much I replaced the the one ill try to get I replacement for the 36
Sorry for the late responce.

You disk marked as 2 has one bad sector that is uncorrectable which happens when a track runs out of spare sectors. Seatools can zero wipe that disk and I found for most such disks they can recover bad blocks. Sometimes disks need a long format to discover bad blocks that cannot be corrected by zero wiping.
