1- Do i need to plug it if i will just use the cdrw to burn and not to listen to cdr/w ??
With the latest Operating system, the audio cable is not neccesery anymore...
2- I think i killed my floppy disk (1.44mb).
I don't think so...Check the power cable of the 1.44 floppy if its proper installed.
5-how to change letter of my 2 cd drive (1 cdrom 1 cdrw) before putting in my cdrw my cdrom was D: and now its E: i would liek the burner to be E: and the cdrom to be D: again
You can do it easily under any OS (Desktop->MyComputer->Properties->Device Manager->CD-ROMs->Choose drive->Change letter)
