This doesn't make a lot of sense to me, the higher bench is the drive in a different system.. The system I bought the drive for is the one it's sluggish in.

I've made sure all bios options are correct, checked the controller settings in devman (UDMA6).. I've even reinstalled my mobo/chipset drivers with no change.

Anyone care to shed some light on this?

Run the Maxtor diagnostic utility and report back what it says.
 
Any particulars?

Passed the "installation test" and the 90 second test passes too.
 
Update:

Just made this drive the only drive in the machine now, formatted and installed XPSP2, loaded all the latest drivers and updates, now the best bench I can get is 25ish MB burst, 24ish MB sustained..

Devman shows UDMA Mode 6 is active, and several free apps I've tried match that..

Then I booted up knoppix and checked the drive with hdparm -t to test, it's coming up with about 47mb sustained..

So windows issue maybe?

It's a MSI 6590 board with the latest bios and Via 4in1's..
 
Sounds like the via controller is shot. It may not like the newer drive, have you googled to see if it's a known problem?
 
Nothing I could find anyway, it supposidly a ATA-133 controller..

But the hdparm deal.. or maybe thats comparing apples to oranges.. I'm at a total loss now.. Hmph
 
Try a different cable I've had hd cables cause weird stuff Like errors and slow down.
 
Tried that too... Two different supposidly shielded cables, and the flat ribbon that came with the drive.. Barely a noticable difference...

What I don't get is how 25mb seems to be the performace ceiling in the other pc.. Coincidence UDMA Mode 1 is 25MB? Everything shows it's set at UDMA 6 though..
 
It only gets 25 MB/sec in a different system as well? Diagnostic and RMA time.

Have you tried benching any other drives on your problem pc to see if they exhibit the same behavior? If so, its probably your mobo/controller...
 
Don't really have any other drives to try..

How could it be the mobo or controller, cable, or drive if it performs fine under linux?

I'm still thinking its a windows issue, but across two installs?
 
Well, I think I might be headed in the right direction.. I've been reading about similar problems with the latest Via 4in1 drivers, but not finding much of a solution..

Older driver perhaps..
 
UPDATE:

I've tried George Breezes Via latency patch to no avail.
I've tried a much older Via 4in1 to no avail.

I also found a Via "IDE accelerator" for all Via chipsets, which too made no difference.

UPDATE 2:
Borrowed a known good IDE controller, same exact results... Same controller and drive in another system, works fine..
