Local MSI distributor send me the latest firmware 150D for my drive and flash utility which can flash ANY firmware.
With new firmware some disks can be written more faster. There is a file where all CD-R & CD-RW's and their speeds listed. I can share this firmware through Inet if somebody wishes or via email.
This drives did not work with CyberDrive's firmwares - only detects in BIOS.
I even try to flash firmware from MSI 40/12/48 - and it works!
When I'd flashed firmware from 32/12/40 Mitsumi my drive die - even don't detect himself in BIOS and even did not ejects tray by the button
I'v bought TEAC 540E and happy - it does everything fine
