Do i have to clear OPC every time?
If those settings give you a bad burn for the 1st burn after those settings, then it's a good idea to clear OPC and then do another burn until you get a good one, chances are your first one should be ok though if you are using verbatim 8x media burning at 4x.
This would be the only time you should need to clear OPC after making those settings active. Even then it's a little bit of being over cautious, different people say different things and some say with those settings that OPC data isn't even learnt.
It's a bit of cross your fingers in this area to be honest.
Personally have found recent batches of verbatim 25pcs printable 8x have given terrible burns like Aone disks around the layer break. It's very much hit and miss, I have 3 ihas drives and all show same behaviour so can't really blame the drives deteriorating.
After doing a kprobe test, i run the disk through a different drive that is capable of reading at 16x at the outer edge, if the speed doesn't drop below 11-12x at the outer edge then i call that a good burn.
I'm contradicting myself here in terms of quality of disks, it's all relative, there was a time when a verbatim disk would never give a bad burn even if it was scratched and covered in dust before being burnt!...Not a chance you'll find a disk like that anymore.This post has been edited by filletofish: Apr 4 2012, 08:28 AM
