We have seen errors that are hard to trouble shoot and when we discover that they have Seagate disks we recommend reading this and performing all the firmware updates.
The Seagate disk manufacture have found a bug in there disks firmware that make it stop working from time to time for about 30 seconds (for example while video streaming or when disk is in low usage).
Barracudy 7200.11
DiamondMax 22
Barracuda ES.2 SATA
SV35
Others as well.
Also some issues with disk performance or raid restarting issues - contact Seagate support to get new fixed disk firmware.
