how can you know diference between LTR-40125W and LTR-40125S ?

mine one is [ LTR-40125W ] with Made-In-China

does LTR-40125S from Made-In-Taiwan ?

which one better ?

after updating the new firmware [ WS05 2002.06.18 ] from [ WS03 ], i still cann't see the label [ Mt. Rainer: supported ] in NERO v5.5.8.2 ?

----------

Mt. Rainer - so-called [ CD-MRW ], the new standard of CDRW disc for UDF specification - from MS-DOS to Windows XP, treated as general 1.44" floppy drive, you can read and write in MS-DOS too !!!

futhermore, by using CD-MRW feature, the writing time reduce to 1-3 minutes insteads of 30-45 minutes of CD-RW, the main feature is the rest of 30-45 minutes of formating processs will be in background once the CD-MRW inserted into your cd-writer !!!

most of brand will not support this feature, but LITEON LTR-40125S surely supported - why my LTR-40125W doesn't let me know it is supported ?

----------

[ WriteCD-RW Pro v3.5 ] is the first software for full support of [ Mt. Rainer ] feature, where [ NERO InCD v3.24 or later ] supports for compatible CD-MRW feature only.

where can i download [ WriteCD-RW Pro v3.5 ] ? someone please share with us ...
