Hm, je viens de regarder le /var/log/dmesg sur mes trois machines.

Sur les deux autres, pour chaque périphérique IDE hdX j'ai bien une ligne style :

hda: 60058656 sectors (30750 MB) w/2048KiB Cache, CHS=59582/16/63, UDMA(33)

Par contre, sur la machine où j'ai le souci, je n'ai que ça :

deathegg:/usr/src# cat /var/log/dmesg | grep hda
hda: WDC WD800BB-00DKA0, ATA DISK drive
hda: max request size: 1024KiB
hda: 156301488 sectors (80026 MB) w/2048KiB Cache, CHS=16383/255/63
EXT3 FS on hda2, internal journal

Sous Windows, ce disque dur est en UDMA 5, visiblement tu n'as pas du tout tort Samva
Vous sauriez me dire comment je peux rétablir le DMA sur mon hda ?
En tout cas merci d'avoir déjà cerné le problème

Je copie le passage du demsg de ma machine :
