Topic: hdparm

[Hugo Snellen]

I hve expeimented with the hdparm paramaters.
I suppose -d1 -c1 -m1 -k1 serve me best..
What is the HDIO_GETGEO_BIG FAILED INPUT/OUTPUT ERROR ?
Where do I register the command at bootup?
regards,

I think it´s on /etc/rc.d/init.d/hdparm  file.

There is a line with other parameters...

I use to use c3X??u1d1m16K1A1
 where X?? can be X34 for motherboard that just support MDMA2 (like K6 II or P II) or X68 for motherboard that support UDMA4 or X69 for UDMA5.

BUT be carefull: choose the wrong one can DESTROY your HD data! So just try on fresh new install (like I do!).

I have seen HDD speed change from 1.8 to 10 / 20 / 30 when using
" hdparm -tT /dev/hd? "   to test it!

I use -d11c1k1 and my speed goes up from 2 ->28!
What I don't understand is that 5.5 claims hdparm as unabled when booting...

d11 is typo should be d1

You should to try this:

/sbin/e-smith/cpmfog setprop hdparm status enabled


And reboot to verify!

Does this enable UDMA on both the primary and secondary ide devices?  ie. /dev/hda, /dev/hdb, /dev/hdc, and /dev/hdd?
