Some more information on the above: OS: 7.2

1. None of the shutdown commands would work so I held the power button down and received a prompt that asked if I wished to force eject the drive, I selected

the force eject and then shut down.

2. Just recently I installed an eSATA _ Thunderbolt_ port multiplier compliant PCIe card (Seritek Q6G) into a thunderbolt external chassis (OWC Helios) (seritek Q6G).

This freeze data transfer also happened when I connected a Firmtek 5PM external tower to the iMac via thunderbolt cable.

The driver for the seritek Q6G was installed in the iMac previous to connection of any of the devices.

Both external towers mount ok on the iMac but have frozen during data transfer.

The initial freeze was with the Firmtek 5PM which is (JBOD)_ I thought that might have had something to do with the freeze_ it being JBOD_ so next I tried the Mercury Elite AL Pro Q2- which is formated in RAID 5. But then froze too.

Anybody have any experience with this?

Maybe I need another driver?

Or maybe some update to my OS?

Any suggestions welcomed.

Thank you
