hard drive performance
 

at one poit i got an error saying that the DMA was turned off on my hda... ever since then, the performance of the drive has been extremly poor... here are some outputs. anyone have any suggestions?? how can i make the DMA be turned on automatically for hda? thanks

root:/home/atlantis # hdparm /dev/hda

/dev/hda:
multcount = 0 (off)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 7297/255/63, sectors = 117231408, start = 0
root:/home/atlantis # hdparm /dev/hdb

/dev/hdb:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 14946/255/63, sectors = 240121728, start = 0
root:/home/atlantis # hdparm -tT /dev/hda

/dev/hda:
Timing buffer-cache reads: 1492 MB in 2.00 seconds = 746.00 MB/sec
Timing buffered disk reads: 10 MB in 3.53 seconds = 2.83 MB/sec

/dev/hdb:

hi
to turn dma on

hdparm -dl /dev/hda

regards

and you can put any/all local commands for hdparm in

/etc/rc.d/rc.local

hey do we need to execute hdparm command everytime the machine starts up or the status is maintained for future

regards
