Installing Windows on External HDD

[rheb1026]

I've read through a few posts that say Bootcamp cannot install on an external drive, which I have tried doing and indeed it doesn't work.

I recently replaced my original HDD with an SSD, so space is kind of limited for bootcamp on the SSD.

If I put the original HDD back in the computer, partition and install bootcamp on the HDD, swap the SSD back in, and then put the HDD in an external enclosure will I be able to boot into Windows? Has anybody tried this?

Fairly certain that is a no go as well - I tried it once, a while ago now and it didn't work. I am not sure if the situation would change if it were a firewire hard drive?
