I've got a new Samsung SM-348B combo drive under Windows XP SP1 and installed the Easy CD Creator Basic s/w that is bundled with it. I've also downloaded the latest Samsung firmware (T505) and Roxio s/w update. I've now tried 4 different types of CD-R (Sony, Imation, Maxell and unbranded) at write-speeds of between 8x and 32x and every one comes out a dud. Sometimes I get a disk that has a readable TOC but never one that is 100% readable. Can anyone help me diagnose this problem further - its getting kind of expensive (7 CD-Rs thrown away so far)?
