I decided in the end that it had to be something like that but I couldn't actually find a bit that explicitly stated that, essentially, the addition of Donna had overloaded the system. It might have been in the gabble somewhere but I think its a detail you have to make up to get the whole thing to hold together.
I also I interpreted the whole "saved to the hard drive" bit as implying they'd been saved to non-volatile memory, but you're right the whole thing makes a lot more sense if you assume the Doctor just says "saved to the hard drive" to imply the general concept to those around him and they are actually all stored in some form of volatile memory.
