Being a total noob is no excuse for providing next to no information then expecting help!
How is your Xbox modded?
How big is the physical disk?
If it's bigger than 137GB, have you set it up to use the space over 137GB as the G partition, or as one large F partition?
Has the G partition suddenly disappeared, or has it never been there?
When you say "When I ftp into my hard drive the drive shows and all my games are still there", where is "there"? Are you saying that you can see the G partition via FTP but not from your dashboard, or that you can see the files via FTP but they are in the F partition?
Which Dashboard are you using? If you are using UnleashX or Evox, have you enabled the G drive in the dash settings?
