I need help with getting games to work on my seagate ontouch hard drive. Games that used to...

Pretty much any USB 3.0 external hard drive with a minimum capacity of 128gb will work. Most gamers use Seagate or Western Digital as their preferred choice, but as I say any brand will work.

I myself use Seagate game drive, Western Digital, Toshiba, as well as Samsung and Maxtor (Both use Seagate drives in the enclosure). The only problem I had was with the Game drive, but Seagate replaced it straightaway, and never had an issue since.

With my Seagate 4TB, Can I moved the games to from my Uncle's Internal Hard Drive to my Seagate 4TB External Hard Drive & still play them without purchasing?

No. It doesnt work like that.

I could not help but notice a few of you mentioned getting a SEAGATE external hard drive once support for external drives is enabled. I work in on computers for a living, STAY AWAY FROM SEAGATE DRIVES!!!!!

A while back, Seagate bought out Maxtor, and with it, millions and millions of their worthless drive platters.

I strongly suggest Western Digital Black or Green series. You will not regret it; it is highly likely you will regret a Seagate purchase in the medium to long run. If you do get a bad WD drive, they routinely overnight replacements to my shop all the time,
and that client's hard drive just works from then on. Seagate drags their feet, and then sends you another Seagate (many times a refurb)

Its like asking for another bullet after you get shot.

Just sayin'

Yer Brother in arms,

The hard drives will work, but games that have been optimized for the Series S/X will not run from it. It can still store them, but to run the games the game would have to be moved to the internal hard drive or you would need the Seagate expansion card.
