Can I change my 1TB internal hard drive for a 2TB internal hard drive on my Xbox One S?

The internal drive is not meant to be swapped.

See, here is something that the original poster didn't think about |(and neither does anyone that says they want to upgrade the internal hard drive)

With the current setup, you can plug in a 2TB hard drive and have a total storage space of 2.5TB.

With the option of updating the internal hard drive, you can take out the 500GB hard drive and upgrade it too a 2TB drive, but that leaves you with a 2TB console, not the 2.5TB with the current setup.

I've got a Seagate 2tb hard drive and the OS is all on the internal hard drive

I I'm not wrong some limited edition from Xbox One X was launch with 2TB Hard Drive, We can Change the original HD 1TB to 2TB too but is more indicate to use External Hard Drive ( By the way we can use until 4TB External Hard Drive without problem)

Ugly looking Console and to small Hard drive. The sad part is MS thinks they made a great console.

1TB internal hard drive too small? seriously?

If it was 500GB I would agree, but 1TB?

Yes, 1 TB is too small for a console intended for hardcore gamers. The One S was release with a 2 TB hard drive.
