Re: Windows Appears to Recognize a SATA Drive as an IDE Drive

You will never under real-world conditions likely see a 100MB/s rating

just marketing hype. Kind of like 1000W ratings for car stereo amps - peak
only and not sustained.

The results for your P-ATA drives are reasonable for SUSTAINED (not BURST
which, of course, is the number that the drive mgfrs use since it looks good)
transfer
rates. The S-ATA readings are not.

I can pretty much agree with the above, especially since the IDE drive is
mostly a software repository. I don't actually run anything from it.

Have you downloaded and installed the latest chipset drivers from Intel?
Yup! I've downloaded and installed every update available (from the
Dell Support site). I don't know if I have an Intel chipset, but the latest
chipset update from Dell for this computer has been installed a year ago.

Have
you
checked to make sure that UDMA mode 5 is selected in DM under Primary/Secondary
IDE Channel>>Advanced Settings?

Yup! I checked them again just to make sure. The UDMA Mode 5 is only
available for the Primary channel which has the SATA drive (There are two
Primary chanels shown in DM), the other one (for the IDE drive) shows "PIO
Mode", although "DMA If Available" is selected just above that entry.

Thanks for the idea. I located and installed three benchmark programs, and
the results were as follows:

Test 1 C: (SATA) Avg 2.7MB/s; D: (IDE) Avg 20.5MB/s
Test 2 C: (SATA) Avg 3.2MB/s; D: (IDE) Avg 45.4MB/s
Test 3 C: (SATA) Avg 2.3MB/s; D: (IDE) Avg 58.3MB/s

The SATA transfer rates are abssurdly low, and even the IDE speeds are far
less than the Ultra ATA 100 rating for the drive. Since the computer is 5
years old, I also tried plugging the SATA drive for SATA 150, but the results
were virtually the same.

Perhaps this isn't a tempest in a teapot and would appear that I do, in
fact, need to get some resolution before going on with my life.

In my DM, when I expand the IDE ATA/Atapi item, all I have there are:
Intel(R) Ultra ATA Storage Controllers
Intel(R) Ultra ATA Storage Controllers
Primary IDE Channel
Primary IDE Channel
Secondary IDE Channel

In the SCSI and Raid Controllers are:
ACARD AEC-6710 PCE SCSI Controller (Windows 2000/XP)
NERO IMAGEDRIVE SCSI Controller

I don't have any SCSI Devices installed, and I think the "NERO" entry is
something that the Nero Burning software installed. If I don't have the
SATA
drivers installed, how do I install them? I've looked everywhere, but
can't
find them anywhere. I checked the Dell website, and installed everything
that I could install. There're three items listed for SATA; 1) A utility
to
manage a RAID Array (which I don't have), 2) A firmware upgrade for the
Promise Serial ATA Raid controller, that I aparently don't have, since I
got
an install error "Adapter Not Found", and caused the machine to fail (I
had
to fight to boot into Safe Mode and return to an earlier Restore Point to
get
the computer to work again, and 3) A Promise Driver described as,"A02
WHQL'ed
Release Version of the Serial ATA RAID controller drivers for W2K and WXP
on
Dimension and Precision systems", which included a disclaimer that it
doesn't
apply to all configurations. I doesn't apply to mine, since the install
instructions indicate a device not in my DM.

Would the drivers be on the WXP Install disk somewhere and if so, how do I
find them? I've explored the disk, but couldn't fine any reference. I've
contacted Dell, but they haven't been much help.

If you will find & run a disk benchmark on your HD, I think
you will find that this is a tempest in a teapot.

Enumerating the device as SATA has NO effect on how well
it's working. My 82801 controller has both parallel IDE and SATA
attached, Device Manager says they're all fine but does NOT
mention SATA at all.

But running disk benchmarks tell me that the SATA is performing
up to spec.

I suggest you do the same and get on with life.
