Speed up hdd ?

[anton]

Hello , well I was just copying files and saw that my speed was about 1 MB/sec :( ... and that's not good.... I believe that's b/c my hdds are in PIO mode, any way to put them into Ultra DMA ? .

thx .

There's an NHF on this very site that will detail how to do it. Its in the hardware section, just click the NHF link above.

The command you're looking for BTW, is hdparm.

Hello, use the command hdparm, for you to check the speed of your hdd do hdparm -t /dev/your device
now to turn dma on you must do hdparm -d 1 /dev/device and to put working in 32bit you do hdparm -c 1 /dev/your device, of course you musto do this as root, mas eache time you reboot your system, this configs will be lost, unless you do a script starting in auto. I think that's all

Be careful with hdparm. I've lost a few filesystems to it from not reading the manpage beforehand. Read the manpage; it'll tell you which options are safe.

Here's what works for me:

hdparm -u1 -c1 -d1 -k1 -m16 /dev/hda

YMMV

greets,

besides to have the hdparm cmd and its associated optimization switches that others use and listed above, once you find the settings you like you can add them to /etc/rc.local as root somewhere at the bottom.

ex:

/sbin/hdparm <proper switches> /dev/hd*

but I would make sure you either add comments somewhere either above or below the command as to the time & date that you made the change!

to make a comment just add a # before the comment text.

ex:

#hdparm settings added 0/0/0 at 3 p.m. by me

because if you dont comment out the comment by adding the # mark before, things will not work 8-)

The benefit of this is that hdparm doesn't have to destroy files etc but can cause programs to act screwey and so on and this will give you a good idea when things might have started to go bad.

Of course, the NHF I refereneced him to said most of that....
