I softmodded my xbox a few years ago with NDURE using, I think, this tutorial and I was successfully able to softmod the original HDD. Earlier this week, I tried upgrading (for a second time) the HDD to a 120GB WD Caviar (using the directions in the same tutorial, but partially modified, see near the end of the post) and (thought) I was successful. However, when I leave the xbox unplugged for a long time, the xbox no longer boots and freezes with the green 'microsoft xbox' logo on the screen after the light on the front turns orange (which is what happens when the HDD normally boots). The only way I can then get it to boot again is to put the original HDD in and set the clock, then put the new HDD in again. Obviously, this gets annoying. I was wondering if anyone else had this problem before, as google turned up no (relevant) results, because I would really like to get this fixed.
I used the directions from that tutorial to upgrade the HDD, but I slightly modifed them. This was due to the fact that I don't have a DVD burner and all the stuff on the old HDD was too big to fit on a 700mb CD. I am pretty sure I followed the directions completely, but DIDN'T copy the e:\apps folder to the CD. after following the normal directions the rest of the way, I FTP'ed into the xbox and copied the E:\apps folder onto the new HDD. I also copied a lot of other stuff to make sure the new HDD was an exact copy of the old. this was because the CD I used was one I made over a year ago when I tried to upgrade the harddrive the first time. the harddrive I used that first time turned out to have the click of death and I went back to the old drive about a week afterward.
Sorry if I posted this in the wrong forum or it was WAY too descriptive. And maybe I might not be as much a noob as some of the people here are. I have a lot of PC troubleshooting knowledge, but just not a whole lot of experience with the xbox and (modern) game system modding in general.
