Hello, Emmeran.
There is no logged error on drive's side. Only timeouts on host's side
with BMDMA engine running. I dunno specifics of the severwork
controller but many controllers with BMDMA interface timeouts the
command if transmission failure occurs, so my primary suspect is still
hardware transmission problem which seems quite common in SATA world.
Can you try the followings?
1. Use different cable and connect the hdd to different hdd.
2. If possible, connect the harddisk to different power supply. (I know
you have juicy PSU but just in case)
Probably applying this to only one machine and leaving the other alone
as control is a good idea.
Thanks.
