As the software is in a partitioned section of the hard drive, any new hard drive would not function without having the operating software loaded onto it. This in itself is not too hard, however, the software will automatically partition any hard drive over 160gb, and will only use the first available 160gb of the hard drive. Therefore, if a 300gb hard drive were installed, only 160gb would be useable.
It must be noted, that if a user chooses to internally modify their unit themselves, any warranty will be voided.
In our initial tests, we found that 160gb was the maximum size that could remain stable in the system, and therefore if additional storage is required, Compatible USB hard drives can be attached to the USB ports on the front and rear of the machine.
