wolny transfer pomiedzy dyskami

[Michał Wcisło]

Witam,

Przegrywam duże pliki pomiędzy dyskami na tej samej maszynie i mam transfer
max 1 MB/s. Jąderko 2.2.22-6 i w logach czasem pojawia się co
następuje:

Dec 28 12:37:49 prestige kernel: hdb: status timeout: status=0xd0 { Busy }
Dec 28 12:37:49 prestige kernel: ide0: reset: success
Dec 28 12:45:14 prestige kernel: hdb: status timeout: status=0xd0 { Busy }
Dec 28 12:45:14 prestige kernel: ide0: reset: success

Czy powinienem dla wszystkich dysków zrobić:

hdparm -d1 /dev/dysk -> włączenie DMA
hdparm -k1 /dev/dysk -> żeby po restarcie pamiętał konfiguracje ?

czy powinienem ustawić coś jeszcze ?
