Oh, like that :-) Well, if you're happier now, I'm happy for you!

Now back to hdparm :-P
I haven't used it to speed anything up yet, but I'd sure like to try. Just a bit worried about possible problems ;-)

Pretty cool

The correct dma modes are usually set by default either way

my hitachi eide laptop drive was missing -m16 -u1 -c3 although I didn't see any performance increase, at least I know I have it set up correctly now

both my optorite cd/dvd drives on my laptop/pc were missing -c3

I have added these settings to my /etc/rc.local (ubuntu/debian)

hdparm can't acces my SATA drive but I would guess it is optimally configured by default

It also might be worth settings -A1 (enable drive lookahead feature) and -W1 (enable write caching feature) on the HDD

Surprisingly enough, you can change some SATA parameters with sdparm - naturally for the most part SATA drives already use the most optimal settings available.

thanks for that information daPhoenix, I downloaded sdparm via apt

sdparm is for scsi drives and works with the sata drives too

lots of information via sdparm --enquire --all /dev/sda and sdparm --all /dev/sda to see valid options

try this too sdparm --enumerate --page ca to see the caching options page, sdparm --page=ca to see the value of WCE if WCE=1 then write caching is enabled

can't see much else to play with though
