As the title suggests; hotswapping to access my Xbox's HD won't cooperate with Xplorer360 or Party Buffalo. Following multiple guides (Link1, Link2), I've done trial and error and still can't get my HD to be recognized by these programs. While tinkering with my Xbox a very long time ago (3 years), I foolishly replaced a file and been receiving the Error 16 prompt. Only recently did I decide to have a go at it to get it working again. At my disposable are the exploitable games: Splinter Cell and Mechassault; a Windows 7 tower with a USB to IDE Hard Drive reader; a Windows XP tower with IDE cable to motherboard; and Xbox AR dongle and memory card (kinda need to look for it) -- what I mean to say is I have the tools to do all this but always get stuck at the FATX error when loading from Xplorer or Buffalo. It's either an error prompt or the HD isn't read/located/recognized when following the unlock procedure to allow my PC access to it. What I currently want to achieve is just to simply replace the file I altered. Fortunately, when I tinkered, I backed up the file so I only need to access the HD to replace the file. If someone could assist me, this would be greatly appreciated. I'd like to revive my Xbox. If my aforemention process won't work, I'm willing to softmod it again -- if by chance that'll work too. (I can't say I really know.) Hopefully doing that won't wipe my saves and music... Thanks!
