Older drive, UDMA not recognized

[None Required]

I have a couple of older drives (Seagate, wd, quantum-4 to 8 GB) I want to
use for removable storage in a ASUS P3B-F XP system (UDMA 33). They are all
UMDA capable, no drive overlays. When mounted in a removable HD bay capable
of UDMA 66 they are recognized in BIOS as UDMA but not in XP. In Disk
Manager they show up as PIO4. I tried Win2K-SP3 also, same problem. They
are jumpered correctly, and I've tried both 40 wire and 80 wire cables
(several). I tried both middle and cable end positions. I tried removing the
Primary and Secondary IDE controllers and let them rebuild without success.

The C drive is a Maxtor 40 GB. If I mount a Maxtor 30 GB in the same HD bay
that I'm using for the others it's recognized fine.

There is a registry tweak for UDMA 66 for Intel chipsets but I don't think
it's applicable since the system will not support it. I haven't tried.

The same drives put in a Win98 system are recognized as UDMA in BIOS and
when check in [Properties] don't have any problems.

Anyone have any ideas about why this is happening?

You can go to run,type:cmd Or boot to xp cd,(recovery)
then typeiskPart
Then:list disk It should show,either/and set to active,
or FORMAT the hd.Type HELP for cmds

I tried this without success. And I'm not sure what is the object. The older
drives in question have been formatted as FAT32 in XP (I want to be able to
take them to Win98 machines also), extended partitions and logical drives
made. At this level they are recognized and useable but just not recognized
as UDMA drives, thus operate a bit slower. So, "working" is not an issue,
just performance and trying to understand this glitch.

Are you saying that in order to be recognized as a UDMA drive in XP they
must have an active partition? Again, BIOS does recognize them correctly.

If you are not getting UDMA speeds, have you installed the UltraDMA IDE
drivers? They are part of the motherboard chipset drivers.

I downloaded Intel chipset drivers from the website and when I tried to
install the program indicated they were not needed. I have installed them on
other Intel chipsets though so know the install routine. I guess they were
installed as part of XP-SP1?

The UltraDMA drivers are not part of XP, SP1 nor the Intel chipset drivers.
They are a separate software package known as Intel Application Acelerator.

My system is using the older BX chipset. The IAA application doesn't seem to
be appropriate, or at least not listed.
