Here's some infos: A few things to check: * Is your PSU powerful enough? (Test with the old RAID-5 set disconnected or with a different PSU.) * Does all fans in the box spin easily? (If the bearings of the old drives and fans are giving out they can draw a lot more power.) * If you disconnect ad4, does ad6 work fine by itself? * Does the problem go away if you replace the SATA cables? * Install smartmontools from ports and run a long selftest on both drives. (Or get the drive tools from Hitachi and run a full test from DOS.) * Is ACPI enabled and does 'vmstat -i' show any IRQ sharing? Maybe try to move some PCI cards around. /Daniel Eriksson
