How can I check to see if DMA is being used on my HD's?

I did a hdparm and my drives seem really slow...like 3MB/sec!

And after I check it how do I enable it?

Thank you

Bizzikid,

Try:

#hdparm -c 1 -d 1 -k 1 /dev/hda

(got this from a related thread:

)

Thank you
 

Thanks:)

That increased my speed 10X's!!!!

I still can't figure out how to make the system boot with those parameters, but I'll keep monitoring the other thread on this subject for it.

Thanks again

Add the command:

#hdparm -c 1 -d 1 -k 1 /dev/hda

to your rc.local file or one of the init files...


That will enable DMA when you boot. :twocents:

You should enable DMA in the BIOS, then booting is also faster, unless your distribution changes the settings to slow again.
