I have a HL-DT-ST DVDRRW GSA-H21L ATA device wich is supposed to read&write double-layered DVDs (It has a DVD+R DL icon in the tray).
Recently I have bought a pack of 5 memorex DVD+R DL but when I insert them on the computer Windows does no recognize them and I can´t format them.
is there a problem with the driver or the unit was designed to work in XP and not in W7?
