I have a HP 8100 CDRW drive. I just bought new CD-RW media and I can't record to it. I have some old CD-RW media and it works fine. I don't think it's my hardware. The media says it can record from 1x to 4x. I have tried setting the burner to 1x and 2x. Still nothing records. I can't even erase or format. With the old media I can. THe new media is Memorex Platinum. The old media is Verbatim. Have there been any changes to hardware or media over the past few years?
