June 12, 20197 yr Hi, i have Problems with my parity since the beginning. I tryed 4 HDD (new ones and slightly used ones) and all of them has "bad" sectors allegedly. But the bad sektors only appear when the VMs are running at the same time the parity sync is in progress.. I have ASrock X79 Extreme 9 Mainboard. No Sata Controlelr Passed trogh to the VMs, my only HW Pass trogh is a TV Card via PCI-e. The thing is, my friend has the same Motherbord and the same TV Card and same settings and he dosent have this bad sector (reading) errors.. can anyone help me with this ?

June 12, 20197 yr By "bad sectors", do you mean SMART reporting bad sectors? Or do you mean parity check error? Parity sync or parity check? Quite fundamentally different things that have different consequences so please don't confuse them.

June 12, 20197 yr Community Expert Those look like connection related errors (e.g. power or SATA cable related) rather than errors on the actual disks. BTW: Rather than posting screen shots it is better to post the system diagnostics ZIP file (obtained via Tools->Diagnostics) as this provides much more information for gurus to give more definitive answers.

June 12, 20197 yr Community Expert Next time please upload the diags to the forum, not an external site. Parity is failing, rest of the disks appear fine, some have a few CRC errors which suggest a bad SATA cable.
June 13, 20197 yr Community Expert If you mean the parity disk a new cable won't help there, it's failing and needs to be replaced.
June 13, 20197 yr Author No.. as i wrote on the beginning.. i changed 4 new drives and all with the same errors.. it must be a HW issue. Today i will switch from SATA3 to 2
June 13, 20197 yr Community Expert The diagnostics posted earlier only show read errors on parity, if there are errors on others disks you need to post new diags showing that.
June 13, 20197 yr Author Its a new drive! Im shure it isnt the HDD itself.. And its always random Sektor that fails to read.. Must be Controller Side
