Not the HD was the culprit but an intermediate router... But still there is the problem that ZFS stalls if I use these drives with ahci, not with ataahci. > If you wish to send drive - my address is: > Topol-2, b34, f150, Dnepropetrovsk, 49040, Ukraine. > Phone: +380503622312. > Do not use courier services, only regular mail.
