December 2, 2025Dec 2 Hi,I am using Unraid for over a year now and recently have recurring problem with Parity disk being disabled. Once I get the error I am removing this disk and re-adding it in the array devices. This trigger parity sync and keeps the Parity Ok for several weeks but then it "crashes" once again and i have to repeat all those steps. I have also set up parity check once a month and very often this parity check does not finish because the speed is like several Kbits and estimated EOT is few hundred days.... During such parity checks I hear some clicking from the disk. I have verified these disks outside of unraid with 2 different apps and everything seems to be OK - no bad sectors. SMART is green for all 3 HDDs. Any help would be appreciated. My parity disk is ST6000VX001-2BD186_ZR15FQC3 - 6 TB. tower-diagnostics-20251202-1539.zip

December 3, 2025Dec 3 Author hmm. You saying that which cables are the problem? The ssd data cables or power cables? If data then they were changed several months ago, if power cables I cannot change them as my psu is not modular.
