I think I wasn't clear enough (probably my bad english) :
when I'm changing the file /etc/hdparm.conf to automaticaly enable the dma on my
/dev/hdc & /dev/hdd dvd drives, my /dev/hdd is freezing and not responding to
any command.
but when I'm using the command sudo hdparm to enable them , there is no problems
and the drives are working fine
