Hi group,

is it safe to use udma instead of dma ??, i ask this because i believe this
would celerate considerably my hard disk.

Its basically the same.As far as setting either to the max,intel even
suggests
setting (where its available) to auto & not at 5 or 6 udma.

This program can measure the performance. If you see a flat horizontal
line for your disk, you could go faster. If the line is tilted, you
may already be getting as much sustained transfer as is possible.

For the higher data rates on IDE disks, you want a ribbon cable with
80 wires. There are two kinds of ribbon cables, and the kind with the
thinner wires, 80 wires, is what you want.

And from this page:

"To enable DMA, right-click My Computer, choose Properties, Device Manager,
click on Device such as "IDE ATA/ATAPI controllers." Double-click on the
controller you want to enable, and in the properties window that appears,
click the Advanced Settings tab. Each device has a "Transfer Mode" that
you can change to "DMA if available." Choose that setting to enable DMA."

It is safe to use, as long as you have the 80 wire cable.
