External Storage keeps disconnecting

Hey all. Really sorry to hear about the trouble you're having.

Genesis1953 has given some great steps and information for the issue you're experiencing. If you haven't tried already please give a different storage device a try to see if there's any change. If you are part of the Xbox One update preview be sure to report
the issue you're having over in the
Xbox One Update Preview forums.

Actually, now that you mentioned updates, that got me thinking. I can't recall exactly when the drive worked before and when it stopped working, but maybe the NXOE update is what's causing it. The Preview Program got a new update in late January that hasn't
gone public yet, right? Maybe that'll fix it.

It just sucks because I've got two HUGE games (The Master Chief Collection and Rock Band 4 + DLC) taking up most of my hard drive space, and I'd love to move them to that drive.

My external uses its own power source and I don't have any issues but it is a drive designed as an external. However, I would guess that most are using drives that pull the power from the bus.

You could try an enclosure that pulls power from its own power source.

An interesting thing happened last night when I was messing around with this.

My console was already downloading a patch (for Rock Band 4, not that it matters) to the internal storage when I connected the external drive. This time however, the external drive actually stayed connected, rather than disconnecting after a minute, as
long as the patch was downloading to the internal storage. When the patch finally finished, though, the drive disconnected after a minute as usual.

Mine has officially stopped recognizing the drive altogether, no matter what I do it won't even show up for the short amount of time it had before. Worked fine last night, not at all today. I understand that things may go wrong and of course I'm willing
to sit here and wait, but I am a little disappointed in the xbox crew for not really making any sort of statement about this issue when I've seen forum posts dating back to 2014 about this issue. I half expected at least a semi-official statement of, "Hey,
we know this is a thing" over the past two years. That would set a lot of minds at ease I feel.
