Hello!!

I have my original Xbox HD. It has the f partition formatted, and evolutionX installed.

All i want now is to change the original HD for a 80-120GB HD. I don't want to lose anything (games, saves, and appz installed).

I have been looking for a tutorial here in Xbox-scene, but couldn't find any

Thanks and excuse my English!!!

you probably have to look closer

Just go to the tutorials tab on the homepage - not on forums.
Open up the hardware mods section and follow Xantiums excellent and foolproof (well, if *I* can do it...) guide...
Make sure you have a disc prepared that you KNOW will work - the rest is easy.
Best...I.
