Blindjim -
Your internal drive could be maxed out, or heavily fragmented. There is so many other possibilities - for instance Itunes could be updated or options changed exactly at the time of switch to new drive.
Fat32 is garbage. Using non-journaled format is asking for a disaster.
If bits would "decay" then checksum errors would be reported all the time with hundreds of thousand of files on computer, compressed files (including jpegs) would be corrupted etc.
The fact that you need partitioning software to split drive or "redo" OS every year tells me that you have PC and Windows (I'm sorry).
Firewire does not load main processor (has own processing unit) the way USB does. It is also more elegant, in my opinion, with daisy chaining instead of hub (only one cable coming out of computer).
Richard_stacy - I'm not sure why you bother with NAS, unless you have network of people using it. It does nothing other than making hard disk slower. Why not just plug external drive into computer. External drives are also cheaper than NAS drives.
