I'm not sure.. The symptoms appear to be similar, but your model and firmware type tell me you have a 7200.10 drive.. If the disk is no longer recognised, regardless whether you check/exchange sata cables, try other sata ports on the mainboard and excluded the possibility of a faulty power supply or other external factors, then you should pretty much have pinnend it down to this type of issue. However, for now i can only say that the BSY bug seems to be restricted to the drive types mentioned at the seagate knowledge base: http://seagate.custkb.com/seagate/crm/self...sp?DocId=207931
