I've had my computer for about a month,it did burn cds fine but now it refuses to recognise a blank cdr. If I use nero and insert a blank cd it spits it out and im told to insert a blank cd which I do and it spits it back out again,the same happens using different brands and also when I try to burn using media player. I had a CDR with just 1 text file on it,I tried to add to this disk and it burnt fine with no problems. I then got a friend to burn a blank text file on cdr and again I burnt fine on my cdrw,So it seems to burn no problem with something else on the CDR,anyone any ideas?
