BW Backup

[crow]

I have made several tries to make a valid backup of Black&White.
I use a Plextor W1210A (firmware 1.08), but the backups I create with CloneCD
have all the same phenomenon: they run from (almost) every CD-RW and CD-W,
but from no CDROM!
I have heard that the 1210A will not make valid copies with firmware higher than 1.04, but I think that is a fake information. I downloaded firmware 1.04 and tried to use it, but I was only able to use 1.05 for downgrade, because the firmwares (.exe and .rom) from www.plextor.com won't work with my drive, only the .bin files from www.plextor.be.

Any suggestions?
