January 10, 20242 yr Hello, I have Unraid server for last 3 years or so. I recently added a 16TB drive to the mix. All was well for some time. But when now I try and run the parity check, it comes down to 3Mbps or so and show 70 days to complete the process. Something is wrong but I can not splot it. Short Smart test from UI completed but long one shows aborted by host. Is there something wrong with the new HD? It's brand new but these days you can never be sure. Diag log is attached. Can I please get some guidance? Resolution: It turned out to be a cable connecting to SATA drive. Replaced it and now clocking 212MB/Sec for parity check. But thanks for looking into this issue. unraid-diagnostics-20240110-0939.zip Edited January 10, 20242 yr by sameerp
January 10, 20242 yr Community Expert Solution You seem to be getting continual resets on disk3 which probably explains the slow speed. You might want to check the power and/or sata cabling to the drive is well seated. I assume the PSU is up to handling the extra drive? BTW: You probably need to disable spindown to get the Extended SMART test to complete. If the drive cannot pass that it will need replacing.
