Solution Steps:

  • Check SATA Cable and reboot and check
  • Replug all Cables and reboot and check
  • Change the SATA PORTS! Sata1 to Sata2 for Disk0
  • Change the SATA PORTS! Sata3 to Sata4 for Disk1
  • Often the Harddisks are NOT damaged!!
  • Looks like a failed Hardware Control by the SATA 600 Controllers with SATA 300/150
  • take new SATA 600 Drives and recheck

Remark: Windows Systems have same Error without Logs, the Systems seems to hang for seconds!
