It is not an option to enable DMA on one of my
internal drives. Anybody know why that might be?
It's a Western Digital drive about 10 Gig. Is it
too old to support DMA? It takes about 4-1/2
minutes to copy a 2 Gig file from it to a Ultra
DMA 4, I guess it is, hard drive. I'm trying to
troubleshoot my so-called giagbit network where it
takes 8 minutes to transfer the same file.

No, because you didn't mention the OS, the ATA controller,
motherboard, etc.

No not at all, it'll support at least ATA33, "maybe ATA66".

Is DMA working properly on other drives connected to same
ATA controller?

The OS is XP Home. The chipset of the motherboard
is VT8366-8233 (VIA) but I can't see the
manufacturer. I did not know the ATA controller
was somehow seperate from the motherboard. Drive 0
has the problem and is the only device on that
cable.

I should try copying a file from the better acting
drive across the network.

Thanks again.

It's not separate, usually, typically is either
southbridge-integral, northbridge integral when there is no
southbridge, or a whole discrete chipped controller in some
transitional periods or well-endowed motherboards that have
more than one controller onboard. The question of which
controller related to the supported features or possible
bugs, nor whether on the board or a separate PCI card.

Your system needs Via 4in1 driver, have you installed that
yet? You might try the newest one at;

You could use the Hyperion Pro instead of 4in1 but it should
not be necessary.

Check ATA/IDE controller entries in your bios, usually they
should be set to "Auto". Your bios POST screen may show
(briefly, a moment before the OS boots) the interface speed
it's using. If that is reported as PIO(n), like PIO4, PIO2,
etc, then you need bios changes.

If bios settings changes and the 4in1 driver don't help,
it's most likely a windows problem.

You need to install at least Sp1 if I recall,

HTH :)

Once done check with Nero Info tool(Configuartion tab),

Do you have any idea why a Gigabyte mainboard with
RAID would not recognize the hard drives attached
to it? Let me know if you need more details. This
is screwing up two computers.
