eeeeek. That's a bit of an issue. From what I know, if companies put their own firmware into a drive, sometimes it's not possible to update the firmware (flashing) with the original hardware company.
Ofcourse flashing your Drive always makes you lose your warranty. Infact the first time I patched my Sony drive it died (site posted a bad flash that doesn't work), but luckily the store just took it back & replaced it with a new one (had to lie how it happened lol, but then also did it the first night, so it looks believable that it's a faulty drive).
Maybe someone else here will tell you different, but have a look at the firmware page h**p://perso.club-internet.fr/farzeno/firmware/ & read to see any info on your drive.
