Having failed to 'upgrade' (change?) from Windows 2000 Professional to XP Professional, I backed up drive C: and reformatted it to take XP. That worked.

However the system has 5 other FAT-32 drives on it (addressed either through a Promise RAID chip on the board --- upgraded to the XP driver --- or through a PCI EIDE extension board). Although the hardware reports that all the drives are present at boot-up, Windows XP finds only 3 of the drives. Moreover, it ignores the content of one of the drives, although it assigns a drive letter to it. The 'hardware wizard' finds all the disks but only assigns drive letters to 4 of the 6.

The motherboard is an MSI K7T266 Pro. The CPU is an AMD athlone(?) 1400+ and there is 512 mbytes of memory. I have disabled the on-board Raid facility in favour of the PCI IDE card
(which has two slots). I had the same problem of missing disks with the RAID facility (which is why I bought the PCI IDE board). Finally, the system workd under Windows 2000 Pro.

I'd be grateful for any advice.

Thanks
