Final update- I ran my scheduled parity check, and it completed with no errors. Thanks to all on the thread for your help. Date Duration Speed Status Errors Parity-Check 2024-04-06, 20:21:09 (Saturday) 10 TB 19 hr, 21 min, 8 sec 143.5 MB/s OK 0 Parity-Check 2024-03-11, 10:59:41 (Monday) 10 TB 19 hr, 39 min, 22 sec 141.3 MB/s OK 6

Got it. Thanks to all for the replies and the information.

Thanks for the reply. Does that imply that a device attached via unassigned devices as an example is not reliable to read/write data from/to?

Hi- Trying to get the UD preclear to work, but running into issues. I was able to install the UD preclear plugin and it does show up when I go to Tools>Disk Utilities>Preclear Disk. I clicked on the drive shown (which is attached to my tower running Unraid 6.12.8 via a USB 3.0 enclosure). I select Start Preclear text, and configure the pop up window as shown in the screenshot. After that, it appears to stall as the status of the preclear never changes from Starting Any pointers would be appreciated. Thanks.

trurl / itimpi- Thanks for the replies. Next time, I'll know how to proceed. Thanks again for the help.

Parity check completed. Last check completed on Mon 11 Mar 2024 10:59:41 AM PDT (today) Duration: 19 hours, 39 minutes, 22 seconds. Average speed: 141.3 MB/s Finding 6 errors Diagnostics attached. Thanks. dlvtower-diagnostics-20240311-2237.zip

Makes sense. Thanks for the info...running correcting parity check now. Will post results when complete.

Thanks for the reply... I'll run the correcting parity check as recommended. Is it a good idea to shut down all docker containers, or just let the parity check run with them running? Thanks.

Posting an update. I was finally able to get some new SATA cables installed. Ran not correcting parity check and it returned 6 errors. Diagnostic log attached. How would I go about determining what the 6 sync errors are?

Sorry for late reply. I'll run a non-correcting check after I get the SATA cables swapped out. Thanks again for the help.

JorgeB- Got it. I'll work on ordering cables and run a parity check once I get them installed. If you wouldn't mind, could you point out what led you to believe that there were ATA errors in the log file? I'd like to learn more about troubleshooting these types of issues. Thanks. When I do perform the next parity check, should I select the box to write the corrections or leave it blank?

Thanks. See attached. tower-diagnostics-20240111-1823.zip

Hi- Running Version: 6.9.2 and the parity check that I have scheduled to run every 90 days threw the following: Last check completed on Sat 06 Jan 2024 07:08:41 PM PST (four days ago) Finding 37756 errors Duration: 18 hours, 8 minutes, 40 seconds. Average speed: 153.1 MB/sec I have a single 10TB parity drive and four 10TB drives in the array which is at 64.6% capacity. What would the next steps be in order to preserve all of the data on the array. I'm not sure how to figure out which drive(s) are failing / throwing the errors. I checked the individual drives SMART reports, and they all show as completed without errors. No power outages to report as the server is connected to a UPS device. Thanks. Edited to add some parity check history for reference.

Went to watch a little Plex and found the server to be unavailable. Checked Unraid, and Plex service stopped. Tried to start it, but got a SERVER ERROR message.
