I have a Sony VIAO laptop PCG-F690K with a dead CD/DVD drive. It is a multi-write drive that writes to DL disks at 2.4x. The problem is that all I get is coasters with the DL media and I have tried many brands. I have updated the firmware several times and tried everything to get it to write to the DL media. It also one time stuck in the run position blocking the boot-up and a DVD drive for a DVD RW drive, and hence i have decided to replace a CD -RW drive.
