Session fixation error

Hello,
I got here two LH-20A1H in two different systems which both seem to have a problem with Sony +RW media unable to erase them. The error is a “session fixation error” when attempting to erase the disk.

However, I can write TDK +R media just fine…so I guess no problems with write once media?

any solution, ideas?

Ok, thanks for all the feedback!

fixed the problem by flashing to LL07 firmware. Liteon had LL0A on their website which caused the problem. They now removed it…
