Assuming DR. PAUL is asking me whether + or - R media was used in the other thread, I can't say since he didn't specify + or - R but simply stated there was a 16x media problem that latest firmware fixed. I've not had any problems with -R media, but I've also read many others prefer to use +R media. I have had problems with -RW failure to erase on 3 different 5005s, and I had to do a full erase on the PC before -RW were re-useable. I've not yet used any 16x media in any 5005, but I did update 3 of the 5005s to the 1101 in order that the problem should be fixed when I do use 16x. Then all 3 of those 5005s were flashed back to hacked firmware to regain advantages stated in post #5 here.
