first of i want to say to all of you since im new here.
now to my problem. i bought a 3520 drive for about a week ago since my old msi burner wasnt working too well. so i had to see if the nec would read my old bulkpaq discs that the msi wouldnt, and of course it read them without and problem at all, so i was all happy about that. a little later the same day i burnt a few discs (eproformance dvd-r discs with prodiscF01 dye) flawlessly, but when i later tried to read the discs then the burner would only read the first 2.5-3.0gb of the disc and then just spin down and refuse to read more, no matter what i did. nor did it read the bulkpaq discs it did before, nor regular dvd movies, all the same. and with nero cd/dvd speed it happened the same, it read to about 2.5gb and then spun down with the error message "no additional sense information". so i, of course tried a few other firmwares, but there was no difference at all, nor if i connected the burner to my promise pci-ide controller.
therefore i thought that the burner was broken and had it replaced, but the new 3520 i got did the exact same, after one burnt disc it wouldnt read any discs at all. so im quite confused and therefore i wanted to see if anyone of u guys might have an explanation to why this happened?
btw, i forgot to say that my old msi dr4a reads the eproformance discs written with the 3520 burner without any problems at all
