Subject : 2TB hard drive for xbox 360

It could be fragmentation but that's unlikely. Try a different USB cable. If that doesn't do the trick, try to defragment it (and not with Windows' utility, Defragr is a great free alternative). If that doesn't do the trick then your drive is just crap.
If it can't access videos in a timely manner, I can't imagine what it does when it tries to load game data :S

I have a 1tb Seagate backup plus portable drive. Space and it has been used to back up all my movies on Xbox live. The Drive has copied all of the movies I have purchased but when I go to playback there is a buffering problem. The skipping/lagging is
intermittent and random with no order and erratic. This skipping happens throughout the entire movie. I have not tried it on all my movies but the three I have played since I moved the movies over have had this problem with playback. Is there anything that
I can do to solve this problem?

I posted a question on another thread re: how to make the external HDD the "system drive" & I was told that you CAN do it by following these steps (I have not verified this yet)

1. Have console connected to Xbox Live to update online gamertag profile. (May need to play and save game to update online gamertag profile or add any recent achievements)

2. Carefully transfer all save data to 2TB external drive.

3. Follow support link
support.xbox.com/.../add-remove-hard-drive to remove Internal HDD

4. Turn on console with external 2TB HDD connected, and without being logged into Xbox Live; Press Guide Button on controller, and download your gamertag profile to external HDD. (Make sure your gamertag profile is working online, by checking to see if save
data can be used on external HDD for games, as new System File should be created to external HDD)

5. Follow step 3 to install Internal HDD, and restart console with external HDD connected.

6. Follow support link
support.xbox.com/.../storage to format Internal HDD (You will need access to back of console for console serial number) Note: If, System File or Gamertag Profile is created to Internal HDD, after format; Just delete them, after you confirm that they are
safely stored to External HDD etc.

Unfortunately this seems to be the case.

You have to download it to the internal drive first then move to the external drive.

Although you can change the destination from within the download queue but this will start the download again from the beginning and leave a partial download on the internal drive(which you can delete)

And yes you can play the games directly from the external drive.

If someone has figured a way to get downloads to install directly to the external HDD then I would like to know too.

No there are no 2TB drives for internal use and making your own is against terms of service and could get you a console ban.
