well for anyone who is interested to know.. i fixed it completely..
I was just out of frustration using my notebook to FTP inside to the UDATA folder trying to rename it under every dash i had.. nothing was working,couldnt rename any folders inside it, or the udata folder itself..
THEN magically when i booted into evox.. it allowed me to rename it.. couldnt believe it.. so when i loaded xbmc got an error, tried booting a game it worked ! looked in the e folder, and there was a NEW UDATA folder..
was stilling having some write issues though, and for what ever reason only in Evox could i rename it./. but i still couldnt get any new games or apps to work..but that was enough info to know, after renaming the folder that it would at least make a new one, and there was some amount of write available... I did try to load a saved game from San Andreas, which it copied to the folder no problem, but it still wont boot up.
So just figured eff it, and wiped the E drive totally, and ftp'd another one i had on back with all the data from the old one.. so now it at least booted the 18 gig coin ops emu i had gotten, which would never load.. tested many other things that werent being allowed to create Udata folders, and all seem to be working well.. so a BIG BIG thank u for ur help, and im sorry for being so reluctant to so what we all knew would be the best way to get it done, but i have never deleted the data folders before on a xbox, and with the write errors i didnt know if they would even come back after it was deleted.. if it wasnt for experimenting around with different dashes tryin to see if i could get any write permissions i wouldnt of had the guts to just delete everything on E.. i would of just waited till i got a new HDD, but not exactly when that would be.. anyways, I have seen this issue talked about on some boards, and NO one had fixed it.. or at least ever told anyone how they had fixed it..
So it seems like AID was a KEY piece of software to get this problem resolved, so thx again u guys for point me in that direction.. still havent been able to get any of the other "bootables" to load, the slayers, or the NEWHD discs.. but as u had told me, AID is all anyone needs =)
I had been out of the scene for a few years, and never done a hard mod, or even considered it until now, out of shear desperation to find a way to format a HDD without a PC.. damn omg, it was so easy, i wish i had started doing this from the start ! softmodding if really the fastest, and simplest way for someone who just wants a basic emu, or media streamer box.. but to really get the max from it, a hardmod is surly the best way to go !
AGAIN THANK U GUY FOR ALL THE ADVICE ! hope if anyone else has an issue about their xbox not able to boot apps or games that have never been played.. that they will be able to find this helpful..

now a question about bios.. im just wondering as per my xbox's situation what other bios are compatible, and what various reasons/features would be of any interest..?
