Lg GH22 Problems, Not specified/logical unit time out

Hi… I’m hoping someone could help. I’ve used my old Liteon DH20A4P for a year with no problems. Yesterday, while burning an ISO it came up with ‘Logical Unit Time Out’. I tried Firmware, different DVD-r, different burn tool, changing IDE etc. Came to the conclusion that it must be the drive.
I bought a GH22 which is SATA and got Unspecified drive instead at the same point as i was getting the logical problem.
Driving me nuts this is!
I’ve defragged, changed Sata ports, disconnected everything and plugged it back in.
Heellllllp me please :slight_smile:
