Ok since I posted i realized a few things.
The memory channel or Xbox 360 as a whole will only recoginize up to 16 gig. When u plug the 2 terabye HD back to the computer, it shows correctly and its a FAT32. (do to XBOX 360 formating the drive and putting what it needed on the drive.) I can move files to the drive when hooked up to a computer, etc....
Anyhow, here is my problem now.
My XBOX 360 20 gig hd works when i transfer my XBLA games or copy a XBOX DVD GAME to the drive. 0000000000 folder for an example.
Anyhow, my 2 terabyte drive... (2 tera MY BOOK essentinal Western Digital external) will not show up in XBOX menu as any games found. (even when i put the games in the same place as the other drive)
I also tried taking out of the XBOX 20 gig hd and just letting the XBOX see/boot my USB external drive and still nothing.
What am i doing wrong?
Also,
When I formatted the 2 tera drive it says it may not be up to quality for XBOX specifications, etc... It also said that on another external hd i have thats new. (SEAGATE FreeAgent Desktop External 500gig)
Thanks for your help. I'm almost there.
Also, what is a good program front end to see your games installed nicely, vs. using XBOX RECENT GAMES within the dashboard?
