Can you please try > to reproduce the issue with the parameter specified. I've been shifting the disks around,trying to find a pattern. So far only the Reds fail, i haven't been able to fail a Toshiba. At first i thought it was because the Toshibas were both on a RAID1 - i'm still testing this theory. I.e., i've recently dropped the RAID; one Toshiba now holds the OS @SATA1, all the others are empty. I'll keep running more tests and document all combinations (SATA ports, kernel parameters, etc) and results. I'll re-read on those parameters and report back once i have something significant. Could the PSU have an influence? It's a Nox Urano 500. Thank you for your time.
