Post new diagnostics. I ran a Lubuntu Live Disk from USB stick for the last approx. 36 hours without any crash or something. After restarting the above mentioned disk is missing. Disk 1 is also missing, but should be HGST_HUS726060ALE614_W2503880 (maybe wrong drive letter or something after switching cables or so) backup-diagnostics-20240220-1727.zip Quote Link to comment

Don't see the Toshiba that was assigned as disk2. How are you getting power to these disks? Any splitters? Too many on one PSU cable? Quote Link to comment

Don't see the Toshiba that was assigned as disk2. How are you getting power to these disks? Any splitters? Too many on one PSU cable? Any way to get it back to system as the "old drive". With the Toshiba hard disk and if it is not defective and disk 1 would be recognized again, the parity would be valid and I only have to rebuild the second parity instead of rebuilding one parity and one data disk which is actually the same as before. I powered of the system, changed power cord and unplugged and replugged the sata data cable and now the HDD is back again. Looking forward if some errors appear again. At the moment I use 3 power cords from one PSU to the HDDs, some of them with splitter, some without. backup-diagnostics-20240220-1918.zip Edited February 20 by aurevo Quote Link to comment
trurl Posted February 20 Share Posted February 20 Disk2 did not get disabled when it disconnected since parity and disk1 already need to be rebuilt. Disk1 has several pending sectors. Do you have a spare you can rebuilt it to? Start the array in normal (not maintenance) mode and post new diagnostics so we can check if any disks are unmountable. Quote Link to comment
