Slow data transfer

[underground]

Hello!!!
My problem is that the data transfer speed is extremely slow...
I copy from dvd to sata hard disk with 10-12mb/sec
From sata to sata (partitions of the same hard disk) the speed is 20-25mb/sec
From sata to ide the speed is 30-35mb/sec

What is going wrong and i have such speeds??
Tell me if you need any hardware info..

Can't anyone help me?

I'm not an expert, but I'm wondering if something to do with DMA settings is coming into play. Unfortunately I have no idea of how to check it.

Me too..i don't know what to check and how...

Problem about low data transfer speed remains...now i am on ubuntu hardy 64 bit
In boot i have the following kernel parametres:
all_generic_ide
floppy=off
irqpoll
pci=nomsi
Without these options i cant boot to ubuntu
Here are the results of various commands

Good question to which I am eagerly awaiting any feedback.
My system shows what I consider unusually low IDE &S ATA transfer rates also.
In fact, the rates you posted are making me really believe my system has a configuration issue. From IDE to SATA transfers, Ubuntu usually reports anywhere from 2 to 8 MB/Sec rates. These are relatively new and fast drives.
