The stores are now selling almost all 80 minutes/700 mb CD-R blanks now, instead of thestandard 74 minutes/650mb blanks. I just discovered that my 2 years old Mitsumi 4801 drive cannot burn CDR with the larger capacity. Luckily a visit to their website found new firmware. I downloaded and updated the firmware on the drive. Now it can burn the larger capacity blanks. Note: The firmware update requires real DOS. I always install DOS on a system first, then Win 2000, so it is easy for me. Otherwise you will have to make a DOS boot diskette first. Do you even have any diskettes?
