oh guys. let clear the A or B confusion!
here's what I have:
TDK 241040B, becareful, cuz on the serial sticker it said B241040Axxxxxx, but on the drive it's AI-CDRW 241040B. you can identify your drive by looking at the front of the drive's lower left, it should said 24/10/40A or B
The drive have BLUE TRAY FACE and TRAY
some people tell me their drive's tray face is white/gray but the tray is blue( that's different than what i have )
Manuf date: Dec 23 2001
FCC ID # PPQRW1002
I'm going to install the drive after this post, and test it then come back here to tell you my drive work or not!
EDIT: I tested, with game cd, music cd and even PSX game cd.. all read with no problem! this drive is VERY QUITE TOO. so happy now
