February 5, 20242 yr Hello Everyone, I'm having a little trouble with my Parity disk. The disk is almost new (it has a couple of months), but today I saw that it has error on it and that the parity is not guaranteed anymore. Before I pull out the disk and send it back in guarantee - could someone help me to understand if it's really a physical defect? The SMART tells me all is ok... Disk is a Toshiba: TOSHIBA_MG10ACA20TE_Z2E0A0NSF4MJ Also I have enabled automatic Spin down. Could this lead to problems if the parity is spun down automatically? Thank you in advance. sekiro-diagnostics-20240205-1510.zip
February 5, 20242 yr Community Expert Looking at the syslog this looks more like a connection issue (power or SATA) rather than a disk failure. Connection issues are far more frequent than real disk failures. Doing an extended SMART test is a good indication of it being OK if it passes

Thanks again for the tip.

Thanks again for the tip. Don't forget it can also be power related.

Ok, fair enough. But then to troubleshoot if the problem is the PSU, I should switch cable with another disk right? Since all other disk don't have problems
