I have shucked a few of the 8 TB WD external drives. They are REDs for the record. What happens is after a while of transferring data to them the transfer slows waaaaaayyyyy down. Then when I restart the system the partition is gone and the disk shows up 13,ooo MB in disk management. I also have one connected through its USB enclosure and it hasn't had any problems. I'm running WHS 2011 and using DrivePool. The drives are connected to the SATA ports on a SM X8SILF. Does anyone have any idea what could be happening here or how I could recover these drives or prevent this from happening in the future?
