P4C800 reports wrong disk sizes, free space in WinXP - Help please

I have problems with reported disk information on one PC.
Windows is confused about disk sizes and free space, and refuses to store data
on
two of the drives.

The PC looks like this:

ASUSTek P4C800 mainboard
Bios 1011.007 Sept 02 2003 (latest revision).

512MB Ram
P4 2.2GHz

The hard drive config looks like:
Primary IDE Master: IBM DTLA 307075 (70 GB)
Primary IDE Slave: IBM DTLA 307075 (70 GB)
Secondary IDE Master: Memorex DVD-MAXX 1
Secondary IDE Slave: AOPEN CD-RW CRW5
Third IDE Master: Maxtor 7Y250MO (250 GB - SATA)
Fourth IDE Master: Maxtor 7Y250MO (250 GB - SATA)

All settings for the disk drives in the BIOS are set to AUTO;
(LBA/Large mode, Multi Sector Transfer, PIO Mode, DMA Mode, SMART Monitoring)
With the exception of 32Nit Data transfer which is disabled.
The settings are identical for all hard drives

I have two boot partitions on the PC:
Windows2000 Server, SP3 , booting from the C drive.
This reports disk sizes and free space correctly.

WinXP with SP1, booting from the first SATA disk.
This version is confused.

Disk size and free space is reported correct for the 250GB Sata drives, but for
the
70GB drives Windows is completely confused. If there was to be any problems
with
disk drive sizes, I would expect them to happen with the 250 GB drives, and not
with the 70GB's.

Free space is reported like this:

Sandra (incorrect disk sizes)
C: Total size 100MB - Free space 68.1 GB
D: Total Size 100MB - Free space 23.6 GB

Disk Manager (correct numbers)
C: Total space 71.5GB - Free space 68.1 GB
D: Total Space 71.5 GB - Free space 23.6 GB

File Manager reports (everything wrong)
C: Total space 100 MB - Free space 16 kB
D: Total Space 100 MB - Free space 50.9 GB

The correct numbers are reported from Disk Manager only.
I am unable to store anything onto the C drive, although there's 68GB free
space there.

Anybody seen problems like this before, and can suggest a solution?

Not sure, but IIRC WinXP and Win2000 use slightly different versions of
NTFS. This might be the source of confusion, but not sure.
