I would replace the cable with a known good cable. A failing power supply can cause all sorts of problems. I would check the PSU with a hardware tester. > Followed by this from time to time: > > Nov 21 16:55:33 r730-03 smartd[17215]: Device: /dev/da7 [SAT], Self-Test Log error count increased from 0 to 1 > Nov 22 11:25:35 r730-03 smartd[17215]: Device: /dev/da7 [SAT], 1 Currently unreadable (pending) sectors STFW I found a good explanation for pending sectors: https://superuser.com/questions/384095/how-to-force-a-remap-of-sectors-reported-in-s-m-a-r-t-c5-current-pending-sector If you can identify the address (LBA) of the bad sector, you could use dd(1) to overwrite the bad sector. If the drive is in an operating pool, this could be risky. Shutting down and using live media would be safer. In either case, you will want to scrub afterwards. David
