Broken drive?

[qanda]This thread is about the Optiarc AD-7170A. Click here to see full specs[/qanda]My Optiarc DVD RW wouldn’t read a lot of DVD:s so I upgraded the firmware. The first upgrade went well but didn’t help. After the second (to 1.M1 - from Diggy’s and Lee’s) the drive doesn’t work at all. A utility of mine says it’s broken. When I did the second flash I also tried some bitsetting since I have som Fuji DVD+R. The drive was strained quite a bit trying repeatedly to read DVD:s.

My question is simply: Is the drive really broken or could a new BIOS flash help?

Does anybody know?
