I have a 980 PRO which is rather new with ~3 months and has a few defect sectors. Trying to repair them with windows CHKDSK results in complains about having not enough space to replace bad clusters.
Samsung Macician Diagnostic Scan finds the errors but trying to repair them with it results in "Recovery has stopped due to unknown error".
SMART says 97% of the spare ares is still available and no issue with the disk.
Firmware is newest according to Magican.
The Over Provisioning menu in Magican doesn't allow me to set anything for the disk as all options are grayed out. I also tried to shrink the partition but it said it's necessary to fix the errors with chkdsk first (which doesn't fix them).
Ouch! That sounds like ticket time. Good luck.
I run 13 Samsung 1&2 TB 960's, 970's, and 980's between my gamer, the wife's, and a new NAS. Haven't had a bad sector in the bunch.
Yeah I guess it will have to be replaced. The strange part is just SMART saying everything is ok and enough remaining spare sectors:
But chkdsk and magican not wanting to use them.
I'm in the same boat, in the same time window. I've got backups failing due to CRC check failed on my 980 Pro. Magician detects bad sectors but during recovery fails due to an unknown error.
Same problem here (980 PRO 2TB). Noticed a few unreadable LBAs today, did recently do a firmware update, but the bad blocks might have very well been there before that and I just failed to notice them (all the LBAs belong to unimportant files).
Something is seriously fishy with these SSDs! Hopefully it's just a fw, not hw problem.
Whoah, running ddrescue on the drive, after many retries, I'm able to rescue the bad blocks and read data from them. That means that this is almost surely faulty flash memory, not some FW issue. :o
