wth my hd is so slow.. according to hdparm

my hd is
30g 7200rpm 100
believe it western digital

from dmesg
------
hda: WDC WD300BB-75DEA0, ATA DISK drive
------

[root@beautifulmind root]# hdparm -t /dev/hda

/dev/hda:
Timing buffered disk reads: 64 MB in 21.11 seconds = 3.03 MB/sec
[root@beautifulmind root]#

is this a question or a statement?

it is a question ... =(

try turning on dma, and tweaking it with hdparm

dma was not included in kernel..

here's what i got

[root@beautifulmind root]# hdparm -c1d1 /dev/hda

/dev/hda:
setting 32-bit IO_support flag to 1
setting using_dma to 1 (on)
IO_support = 1 (32-bit)
using_dma = 1 (on)
[root@beautifulmind root]# hdparm -t /dev/hda

/dev/hda:
Timing buffered disk reads: 64 MB in 1.89 seconds = 33.86 MB/sec
[root@beautifulmind root]#

cool
thanks

You can use hdparm to find out all sorts of info,

Code:

bern@grendel bern$ su -c "hdparm /dev/hda"

/dev/hda:

 multcount    =  1 (on)

 IO_support  =  3 (32-bit w/sync)

 unmaskirq    =  1 (on)

 using_dma    =  1 (on)

 keepsettings =  0 (off)

 readonly    =  0 (off)

 readahead    =  8 (on)

Aussie,

I know this is an old post, but I found it searching for hdparm info.

The new -I for information vs. the old -i gives a lot better information. Anyone tuning their hd may want to know this.
