I have same problem on ASUS RS120 with Seagate ST3250820AS/3.AAC drives (disk loses, system reboots, slow read/write speed), but I think this is drive problem - all drives has high Reallocated_Sector_Ct value in SMART (above 130 reallocated sectors after few weeks, some drives has more then 100 after few days). Please let me now, if you also have nonzero Reallocated_Sector_Ct in smartctl -A output. I will test those servers with brand new Samsung drives, hope that it helps. Miroslav Lachman
