Device is disable, contents emulated (disk failure) - What should I do?

[yukij]

A problem with the hard drive. The disk is new, it worked for about a month, after which a small number of UDMA CRC errors appeared (10-15 within 2-3 days). After that, unraid reported: Disk 1 - ST8000NM017B-2TJ103_WWZ17Z1T (sd) (errors 513). The question is what should I do, since according to the analysis the smart disk is in excellent condition. How can I correctly determine the cause of this error?

Replace the SATA cable and if the emulated disk is mounting and contents look correct you can rebuild on top.

"rebuild on top" - is it to restore from parity to the same "broken" disk? I changed the sata cable, reconnected the disk and started recovery from parity (checked the emulated files, everything is fine).  Is that right?

If I'm understanding correctly it is, it's this:

I did according to this instruction, yes. After rebuilding parity (after 8 hours), I will check all the files. I think everything will be OK. Thanks
