Desk top Model DX4428 will not recognize blank DVD's or CD's, both RW and R. I have 2 DVD drives. Both will play DVD's and CD's. Will not burn either. error message says unformatted? Cannot format> Have bought new DVD's and CD's HELP! I am considering a small dose of C4 explosives
If you have the original drives, they may need replaced. Those are probably read only devices since they play media. Without pulling the devices to get the numbers from the cd dvd drive, It's hard to say definitely.
