Xbox FUBAR'ED - Big Time Help Needed

[Berzy]

just created a new dvd-r with the updated evox iso on it.
and i did manage to FTP my xbox, but now i have all these weird folders in there like
c:/back-up
c:/Fonts
c:/xboxdashdata.10027100
c:/xodash

and compairing my c: now to the one i backed-up when i first put the mod in, over 90% of the files are missing. i only have 7 in total.

so i was wondering if i should just replace the original c: & e: and start fresh.
also how would i do that. just a simple copy & paste.
