I had a TDK 24x10x40 (X model) and failed at burning MOHAA. Once I read that there were differences between the TDK models, I took mine back and exchanged for a B model (Lite On). I immediately noticed that the tray is a blue color compared to the white of the X model. Also the B model has only one red light compared to the two green lights of the X model. The ROM for the B model is 57S4.
Then I used FutureProof’s settings for CLONECD and was able to burn a good copy. My two test CDROM’s were a Soundblaster 8x speed CDROM (very sensitive to failed backups) and a ACER 24x. Both of these CDROM’s would not play the previous MOHAA backup. But once I switched, no problems.
BTW, COMPUSA has the TDK 24x10x40’s (B model) for $109.00…there is also a $50.00 rebate. So in effect the drive will cost you $59.00. Not bad for that price!
