Won't detect large hard drive

I have built several PCs. I'm trying to add a 200Gb drive to my current PC. Am replacing an 80Gb drive which has been working faihfully. Whilst it is recognised in BIOS and can be populated in 'System', it doesn't show up in explorer, so can't do anything with it. Rechecked all connections, BIOS settings, and jumpers. Sent it back to supplier who tested and confirmed working ok.
It's not an old board - Asus A7V8X Raid Mobo with XP2100. Has anyone else seen this problem? I have read there may be problems with HDDs over 137Gb and BIOS versions, but symptoms are not same.

Hi there. Have you already partioned the drive. Might be helpful to do that if you haven't and maybe it will help? Not sure if that will do anything but that's what I would do.

I would assume it is a BIOS setting but that should be easy to check with the Motherboard manufacturer.

Thanks, but trying not to partition. Its for video editing, so trying to keep it intact, otherwise would buy smaller drives. Waiting for a response from ASUS

It looks more like a Windows "issue" rather than the bios. Partitioning would sort that out. Have you checked what the max partition sizes is for the version of Windows you are using?

Many thanks. You are absolutely right. Its a 'function' of Windows XP that I've not seen documented - all new hard drives have to be 'allocated' (Does anyone know what this is all about?)
Control Panel>Administrative Tools>Computer Management>Disk Management ... the new drive doesn't appear in the list of active drives, but scroll down the list of drives and you'll find it - unallocated. Inspect properties and 'allocate' it ... BINGO!!!. Thanks again for the pointer.
