hdparm -X 69 /dev/hda also doesn't help.
but for the same hdd, with mercury mb and 815 chipset, in mdk91, I
used
to
get
buffered disk reads nearly 29 MB/s.
How about telling what kernel version you are running,
and what m/b and chipset do you have...?
I am running mandrake 9.1 with the shipped kernel, in asus a7n8x deluxe
motherboard with nvidia nforce2 chipset and amd athlon 2400+ with 256 mb
ram.
I was only wondering when the same system is giving good transfer rate
with
knoppix, what tweaking is needed in mandrake9.1 to get it?
Upgrade your kernel to the 0.25mdk from security updates,
or Danny's 0.22mdk, you can find at:
ftp://sunsite.uio.no/linux/Mandrake/Mandrake-devel/unsupported/MandrakeClub/9.1/i586/kernel-2.4.21.0.22mdk-1-1mdk.i586.rpm
ftp://sunsite.uio.no/linux/Mandrake/Mandrake-devel/unsupported/MandrakeClub/9.1/i586/kernel-source-2.4.21-0.22mdk.i586.rpm
or from your local Mandake mirror in it's path:
Mandrake/Mandrake-devel/unsupported/MandrakeClub/9.1/i586/

here it is udma5 where as in mdk it is udma2 only.
I tried /etc/sysconfig/harddisks with X 69. still no use. Any help to change
udma and speed will be appreciated.
