Which IT shop in Singapore still sells this device?
No idea, alternatively you can buy a DVD writer for under 40dollars, which will write CDRW and CDR
I think CD Rom is not writable right? the dyes inside the cd are pre-burnt by the factory
AFAIK, no one sells CD Writers anymore. You can instead get DVD Super Multi drives which read every CD and DVD, as well as burn CDs and DVDs. Around $30.
Unless your system in question is unable to use a DVD Writer (Which shouldn't be the case)
CD writer...most are selling DVD Writers already. and another question would be: internal or external? the price is different and the interface in which they connect to the system would be different too.
