Default hard drive over 2tb with legacy bios

Will a computer with legacy bios be able to use an external drive greater than 2tb? I am hearing a lot about legacy bios computers like mine don't support drives greater than 2tb without having to create a second partition. I am pretty sure it applies to internal drives but there is no word on externals over 2tb

You'll just have to format it as GPT and it should be fine as it's not the boot drive.

Ohh. So it only applies if it is a boot drive. Now I am debating whether to get a 3-4TB internal or external. If I go internal I would take the 1.5TB out and stick it in an external enclosure as backup.

Still be cautious, many times a 3-4TB drive MIGHT work, but most controllers, older ones especially are limited to 2TB tops...

I will probably go with an external so I can have the data accessible from my desktop and my various other devices. The only issues I have are if that limit will apply to usb storage. The other thing I am wondering is if newer externals have self diagnosis like smart. All the ones I have now don't report smart data so I would have no idea if the drive was about to fail or not

SMART data is only available to the controller... Most enclosures wont report SMART data over USB at all.
