using hdparm?

box_l · 09-29-2003, 04:04 AM

having read an article in linuxformat about speeding up your hard drive i decided to give it a go.
hdparm will give me all the info that i need, but will not reset the parameters i wish to change.

if i type:
hdparm -c1 /dev/hda7 (my home)

i get the response:

/dev/hda7:
setting 32-bit IO_support flag to 1
HDIO_SET_32BIT failed: invalid argument
IO_support = 0 (default 16-bit)

i have tried this with other parameters such as -m16, -d1 etc.
but get the same response.
where am i going wrong??

you are attempting to set these attributes on a disk partition and not an actual hard drive entry. use "/dev/hda"

many thanks for the swift and correct response!
i can now speed up my drive,
and probably damage it in the process!

great, i made my changes and now console one opens like lightning,
but... when i reboot all these settings have returned to previous values?!
why?
how do get them to stay?

hdparm is a temporary command that keeps the settings only until you reboot your pc, to keep them add the settings to fstab

umm.. i thought you could only appy these settings to the drive not the volumes?
do you have an example fstab?
