dmb06851 I long ago lost the bit of paper which came in the cylindrical package holding blank discs. I have forgotten if they are -R or -RW. The printing around the centre hole doesn't tell me. Is there a way of finding out?
[deleted] Normally CD-RWs have a darker surface than a normal CD-R (from my experience anyways). Also you could try erasing it in Express Burn, if it has issues then it's probably not a CD-RW.
