WARNING Re: 3TB drives have arrived

3TB is too big for most motherboard chipsets. Nvidia chipsets currently can’t handle more than 2.19TB. And yes this includes Macs unless they are very recent and are UEFI-compliant.

Nvidia Forum posts about lack of support for drives above 2.19TB. USB caddies are also pretty hit and miss.

Look for UEFI-compliant Bios and Motherboards.

Also Windows XP can’t count that high without 3rd party $ drivers.

Some Western Digital drives ship with a PCI Express card that enable Vista/Windows 7 OS to see the 3TB drive.
