IIRC, you can match up the ata17.00 with what drive it's talking about by looking at your kernel boot messages. The first thing I would do is switch out the SATA cable and see if the problem persists. If that doesn't work, run a scan of the drive using the manufacturers scan program. > hi everyone these are the following tests i've tried and the results journalctl -f | grep ata Jan 13 12:37:13
