Supplied with my MSI Neo2 K8 Platinum computer were two WD2500JD-50GBB0
250GB drives.(no raid) I have AMD64 +4000 and 1GB ram and a firewire card I
use for DV video capture.

C: is where XP prof resides and is 50 % full

D: for captured avi. Some files are are 50GB and this drive is 90% full

Problem is that C: has 23Mb/sec transfer and D: only 7MB/sec.

Am I correct that in XP DMA is on by default for these drives?

In looking at the bios I see:

IDE Pri master - none
IDE Pri slave - none
IDE Sec master - DVD-RW
IDE Sec slave - DVD-ROM
IDE 3rd master - 250GB sata
IDE 4th master - 250GB sata
IDE 5th master - none
IDE 6th master - none

On chip IDE channel 0 enabled
Pri master PIO - auto
Pri slave PIO - auto
Pri master udma - auto
Pri slave udma - auto

On chip IDE channel 1 enabled
Sec master PIO - auto
Sec slave PIO - auto
Sec master udma - auto
Sec slave udma - auto

Sata1/Sata2 DMA transfer - enabled
Sata3/Sata4 DMA transfer - enabled
IDE DMA transfer access - enabled

Is there anything above which can help me understand why the D: drive is
significantly slower than the C: drive?

Even with both drives defragged Premiere Pro is jerky on video capture and
playback

thanks,

Beemer

I got lousy disk transfer rates also on my K8N Neo2 until I installed
the Nvidia IDE driver which is part of the 5.1 Nforce driver package.

With a 90% full disk I'd look at fragmentation levels (which you say you
have done) and the size of your swap file. As a rule of thumb, full disks
will almost always be slower than empty disks.

YMMV, etc.

HTH.

Bob,

I carry out daily defrags. My Western Digital disks are rated at 150MB/sec
transfer rate with 7.5ms latency. Even with my 50% full drive I am only
getting 23MB/sec and 210ms latency. My swap file is on this drive (but not
XP) and is 1.5GB.
Maybe what I'm seeing is normal but I just don't know. However whats the
point of specifying 150MB if that only applies when the drive is empty!

(Sorry for self reply)

After reading further I now think that my SATA connection is fine as I
learned that both are Master. However I do not know what else I might need
to do to get faster transfer. Both SiSoft Sandra and XP tools report
23MB/s and 7MB/s. In the bios there are DMA transfer settings which can be
seen above and are all enabled

Still looking for help.

I'v got 1 x WD2500JD SATA that's slow. I noticed Win XP sets it to PIO mode (rather than UDMA5). When I boot the BIOS shows it as UDMA5 but when windows finishes loading I see (in properties) that is changed to PIO.
With some moving of cables I sometimes get it to stay in UDMA5 but since a week or 2 that does not seem to help.
It's the only SATA i have. The other ((P)ATA) drive works fine in UDMA6.

What to do next? Thnx. NV
