[Snake]

Hi,

I got problems copying games with CDRWIN... My burner is an Delta CDRW 2x. well, before everything was okay, I burned many cd's with it, but now it can't, when i press "Start Recording" this message comes up

"Error: "WRITE" command failed on device 0:1:0
"Read/Write error or bad medium detected (04h 00h 02h 03h 73h 03h)

What's wrong?

btw, it works with NERO, dunno why cdrwin doesnt work..

PLEASE HELP!!
