Hi all, I ran into an issue the other week where my server was under heavy load, and suddenly started reporting current pending sector and offline uncorrectable errors on a disk. I replaced the disk with a new one, which rebuilt fine, and mounted the problematic disk as unassigned to run some diagnostics on it. After running a preclear, both the pending sector and offline uncorrectable errors disappeared, to be replaced with 7 "reported uncorrect" errors. I can't seem to clear these, despite having run multiple pre-clear cycles on the disk. SMART diagnostics for this disk (run after the pending sectors & offline uncorrectables disappeared) are attached. Is this drive safe to use at this point? I've pre-cleared it 3 times since the error event, and the reported uncorrect values are not increasing, but I was kind of expecting some values to appear in the reallocated sector count of the SMART details after running a preclear. I've had the drive plugged in for a week now and have been randomly writing stuff to it without issue. Thanks! ST8000AS0002-1NA17Z_Z84058Z5-20230623-0823.txt

Ok - great to hear it doesn't seem like a disk problem. I will keep an eye on things then. Thanks!

Hi all - I had a situation a few days ago where one of my drives threw a bunch of read errors and then red balled. I ran an extended SMART test which came back fine, and have just finished rebuilding from parity back onto the drive that red balled without any issues. I'm curious if there are any indications in the logs that I am missing as to what could have caused this? I'm planning on reseating all of the cables this weekend, but worried about potential power issues or something with the SATA controller - but I'm not sure how I would identify this or what to look for in the logs.
