I have a Seagate st3160023a and a st340016a. Both disks are seen by the
ASUS A7A266 BIOS as being DMA/5 which is the way it should be. I have down
loaded an app from the Seagate website which separately confirms that the
disks are both DMA/5.
So far this is good. I have constructed my boot hard disk on st3160023a as
the disk seems to be more grunty - more cache etc. When I boot XP,
st340016a is shown as DMA/5 and st3160023a is PIO/4.
(Presumably) Because I am using a system disk that is rated as PIO the PC
cannot use a new DVD drive nor the write functionality of the old CD writer.
The system log does not report any CRC or timing errors from the disks.
Some sounds stutter eg the windows logon sound. Presumably the OS can't
feed the sound to the sound card when it is loging in a user.
In an attempt to get the system working I have
1) pulled all the non essential cards from the system
2) performed a fresh install of xp professional
3) applied the latest patches to xp via windows update
4) replaced the ide cable with another 80 conductor cable length < 18"
As seen via XP at no time did the system disk, the st3160023a, do anything
other than PIO/4 and the other disk on the same IDE cable.achieved DMA/5.
As seen via the BIOS both disks are DMA/5. The spec of both disks is that
they should achieve DMA/5
I have spoken to Seagate who advise that this is an XP issue. Seagate
referred me to
http://support.microsoft.com/default.aspx?scid=kb;en-us;817472
Microsoft have supplied the patch referred to in 817472
I have installed the patch and changed the registry.
AND
No change
Request
=====
Any comments suggestions welcome on how to get my PC to recognize that it
has a DMA/5 disk not a PIO disk.
OR
Are there any logs where I can track xp's decision process on down grading a
disks access speed at boot time
Thanks
