Dear PCBUILD forum, I just bought the above 8x8x24 Yamaha CDRW for my home PC (Cel 233, MB MSI6309, 64MB). I use the supplied Adaptec EasyCD 4 and DirectCD 301 and have updated to 401d and 301d. The CDRW runs well for writing CDRW, but many CDRs that I created using my office PC, HP 2x2x8 7200E CDRW, are not recognized by the Yamaha CDRW. It always says that the media hasn't been formatted and the disc light stays orange not green (not ready or no disc). Any idea and suggestion of what's is wrong? Appreciate your helps. Thanks.
