Firmware 1.02-mk seems to work without any issues.

It's no option to return it unfortunately because i still use this drive since ~1 year. Until now i used 1.02 stock firmware without any issues but i had some problems reading discs so i decided to give the MK firmware a try. I will now try to use 1.02-mk and as latest option i will order a new drive.

After installing firmware 1.03-mk from the latest firmware pack the drive is sometimes not available. Even after a fresh reboot. Sometimes it's available and it's possible to start reading a disc but during the process of reading the drive becomes unavailable again.
