This despite the SATA spec stating clearly that such a command should/will have no effect. I suppose libata does this already, but just in case not.. Something simple to check up on. -- Mark Lord (hdparm keeper & the original "Linux IDE Guy") William Knop wrote: > > Ah, well all of them are Maxtor drives... One 6y250m0 and three 7y250m0 > drives.
