but after you will have to unlock the hdd to put it in the next xbox to re lock it

I have two folders on my pc called C and E and I just ftp the contents to c and e on every xbox I tsop flash, I do it this way as I don't have 42 consoles to mod

If I come across a windbond chip i just pop in an a linux flash method cd, but from now on I will be using XBlsat OS.xbe to do the same task saving me from fumbling around with cd's
I have just brought 9 xbox consoles for $4 so I will probally set up a hdd as you suggest that is a real good idea I have a few spare 8gb hdd's lying around!
