And you mentioned any 2.5" sata drive would work, but I was under the impression only the same drive would work? Was this fixed in a firmware update?
I don’t know the answer … but if i had a spare 2.5 sata i’d give it a go see if it works (nothing to lose?)
Could only find one post where a user mars109 replaced his with a 60gb Seagate drive
Also, answering another question … the WDTV Live Hub will work without an internal Hdd and will also work with self powered usb external drives*
* I have 3x 1TB WD Elements USB Pocket drives and they work fine without external power
In my setup pic i have
1x USB HUB (unpowered externally)
1x WD 1TB Elements USB HDD (unpowered externally)
1x Seagate Freeagent USB HDD (unpowered externally)
2x WD Elements USB HDD (powered)
1x Seagate Freeagent Desktop USB HDD (powered)
The WDTV Live Hub sees them all 
And i still have one free usb input on the WDTV Live Hub
