Is it really any different to how a PC and just about any device with a hard drive boots, no-one puts the OS in ROM anymore!

I'm sure it's possible to have one track that's low density and readable without all the clever trickery usually used, then a minimal firmware bootstrap loader that knows only this track could load up the full firmware. Sounds like a common practice, should be ok provided the bootstrap loader knows how to re-write the firmware track!

With the amazingly low prices these drives sell at I wouldn't be surprised at that level of penny pinching.
