Specs: Windows XP Home
Will an Asus A7N8X mobo recognize a 1 TB drive? I can't seem to find anything in the documentation.

Check the manual. The IDE is described as 2 x UltraDMA. And in the BIOS section, it says that when LBA is enabled, 28-bit addressing is used. The max HDD capacity recognized with 28-bit is 128GB. The only way to run a 1TB HDD would be to install a controller card.

How about SATA? I'm currently running a 500 Gb and a 300 Gb HD from the onboard SATA, not in RAID. It sees them just fine, but I don't know if a TB might pose a problem.

Watch the POST screens at start up to verify the SATA drives are actually being identified by both the model and the FULL capacity.

Windows may see the full capacity but if the BIOS doesn't you will eventually end up with data loss or corruption.

Thanks--I THINK the BIOS is seeing the full capacity, but I've never actually watched the boot to verify that....

Sorry to take so long, all--

Yes, the BIOS correctly identifies both of my hard drives and their capacities. Whew!

That conflicts with what jam posted above. Are you POSITIVE the FULL capacity is seen. Post the information. Hit the pause key to freeze the screen. Any key to restart.

If verified then I suggest that you just partition it by creating a Primary partition of 30 or 40GB. Do not create any additional partitions at that time. Do not have any external hardware like flash or USB drives, printer, scanners, etc connected.

After installing and updating Windows you can deal with the remaining unallocated space from within Disk Management. Look at the link below for suggestions on partitioning.
