With version 2.8.3.1 of CloneCD try these settings if you haven't already.

Read:
Speed = 8x
Settings = the top two only ( I can't remember the exact wording and can't look it up, I'm at work)they are something like:
*Read subchannel data from data tracks
*Read subchannel data from audio tracks

Write:
Speed = 4X
Settings = only the top one "don't repair subchannel data" <<--I think that is the correct wording.

If this doesn't work try using version 2.7.2.4 and you might have better success.

Cybercop...

PS...many people I have spoken with have told me that evey though their Plextor drives claimed they were compatible they still couldn't use it..granted I wasn't physically there but if they followed my instructions to the letter and the drive was compatible it would of worked..
