Dotaz: Jak zjistim UDMA disku?

[pepe1]

Zdravim mam starsi desku i815 ms-6337 a je to zrejme nejaky zmetek, nebot od jejiho zakoupeni ukazuje v WinXP na primary master UDMA4 a na slave UDMA5. Pokud necham zapojeny jeden disk tak je vzdy UDMA4! Aktualizace biosu nepomohla a asi neexistuje zpusob jak to odstranit. Pouzil jsem ide accelerator v XP a master se tvari jako UDMA5. Zkousim Ubuntu a nevim jak zjistit v jakem rezimu disk jede. Bylo to tady nekolikrat reseno, ale nevim cemu verit. Kdyz zadam hdparm -i /dev/hda tak se zobrazi:

josef@ubuntu:~$ sudo hdparm -i /dev/hda

/dev/hda:

ale zadny mod neni oznacen *!

Pokud zadam hdparm -I /dev/hda :

josef@ubuntu:~$ sudo hdparm -I /dev/hda
