Slow HDD


Recommended Posts

hmm... have you tried using the EDP package and see if that makes a diffrence, the dsdt.aml from dsdt contains some stuff for the HD


Btw.. what HD model did you buy ?

I use the EDP dsdt with my additions so the ATA stuff already hear. (else KP at startup, I know).

I think the problem is not in HDD model, and not in slow CPU. The problem in Powermanagement when HDD became energy-saving slow mode. Don't know where it is.

Today, after some tuning it works more or less fine.

hmm.. i noticed that in bios for your model there is setting for configuring if you want the machine to be "quite" or have "performance" .. did you fiddle with that ?

Yes, I set "performance" and now it works more or less fine. May be another changes in my system gave me effect... dunno.
