EXAMPLE:
Code:
hdparm -d 1 -c 3 -k 1 -S 253 /dev/hda
the -d 1 flag sets DMA to "on"
the -c 3 flag sets the I/O to 32-bit/ with sync
the -S 253 flag sets the Vendor Specific spin down time.
AND the -k1 flag keeps these settings intact between reboots....
read up on the different flags, options..........
man hdparm
in Slackware all this goes into........./etc/rc.d/rc.local
