Magic V and HDD

[NatureX]

Hey guys, gotta quick question, this does regard HDLoader as well.

Ive been reading that you can load your backups into the HDD as long as you have a mod, which I do I have the Magic V. Anyhow, my question is, how do I enable the modchip with a HDD in it?

I ask this because, when I got my SOny HDD, I installed it, and attempted to play bacup games, now the system told me that they werent original ps2 games.

How do I enable the modchip with my hdd in? I know it can be done because someone with the hdloader and a magic v has installed backups.

Thanks
