February 27Feb 27 Hi there,I have recently added a few more drives to my system and have now been struggling with seemingly random dropouts. The drives always seem to test fine, i re-insert them, the system rebuilds properly and then after a few days of good operation, a drive will randomly drop out. I have moved drives to new bays, replaced sata cables, etc... the problem still seems to reoccur.In my forum searches it seems sometimes folks solve this randomness with a PSU replacement. I am curious if anyone here can have a look at my logs and see if the issue may be something else. This is just a home server for media sharing so nothing really critical but i would still like to avoid a worst case scenario.Let me know if i can provide any other logs/details. drive log most recent drive dropout.txt tera-bit-syslog-20260227-1704.zip tera-bit-smart-20260227-1105.zip

You can normally split a molex->SATA 4 way as the Molex connector can handle more current.

February 28Feb 28 Community Expert There are no corruption errors detected in the pool so far, but there are in the Docker image, and the balance failed with this:BTRFS error (device sdb1): read time tree block corruption detectedWrite time corruption is the one that mostly suggests bad RAM, but read time can also be that, so, I would recommend running memtest, after that also recreating the Docker image and monitoring for new errors.
