The spec sheet shows 2 TB discs so far. I've got one of those lying around, waiting for my Fluxx to be delivered. But since 3 TB models become available and are not too pricy, I'd like to know whether it is possible to upgrade my HDD from 2 to 3 TB.

This would be a pure software thing as far as I can tell, so it might be possible that the player can use such large disks. But at the time of writing of the spec sheet, 3 TB disks were not available as far as I remember, which is exactly the reason I ask.

The 2TB limit has to do with the filesystem layout used on the harddisk.
To exeed the 2TB limit they should add a GPT behind the MBR, that will increase the limit to 9.4ZB (ZettaByte).
Of course the operating-system has to support this!

Another solution could be creating multiple partitions on the harddisk.

I know, it actually should be a pure software problem. Including GPT support in their kernel is not that difficult I assume, so it comes down to whether they want to do it.

So is there anything official regarding this matter available from perhaps a moderator or even a developer?
