hdparm enabled but still slow copy


Hello


I have either dma enabled for my dvd and hard disk. My hard disk is divided into
2 partitions hda1 hda2

the settings are saved into rc.local
like as follows:


hdparm -d1 /dev/cdrom[/CODE]
Code:
hdparm -d1 /dev/hda

hdparm -d1 /dev/cdrom



[CODE]dev/hda:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 65535/16/63, sectors = 80026361856, start = 0

The problem is that whenever i copy avi files which are huge files
my copy speed is 9mb /sec

can i fix this somehow .

do i have to enable dma for each partition for example ??
ps dma works fine with my dvd and with the hda1 which is the slackware partition

the hda2 is a storage space


Thanks in advance

Are you slaving your dvd off of your hard drive, or is it on a separate ide channel?

Code:
hdparm -tT /dev/hda

/dev/hda:
 Timing cached reads:   1176 MB in  2.00 seconds = 587.50 MB/sec
 Timing buffered disk reads:  148 MB in  3.01 seconds =  49.21 MB/sec
