and it runs pc games without no trouble i can play cod waw online without it cutting off and only does that when i aint doing to much with the drive even copying files to it uninterrupted lots of files

When the drive comes or goes does you usb bus give you an aduible "ding"? I mean the ding you get when you plug in a device or unplug one.

While I am waiting for your answer about the ding. Take a look at this tutorial.

Device Manager : Hidden Devices

yes i get the ding and then a message

Do you scan?

i have i think not sure
most of the time i just close that
a scan wouldn't effect the way it reacts with my 360 or change files that are on the usb would it?
yes im 4 sure i scanned it now i remember this

Since you want to maintain the disk and enclosure as is for the xbox, the only thing I can think of is to clean the unused entrys from your device manager per the link in post 22 above. It might help but I don't hold a lot of hope.

your talking about this correct?
Device Manager : Hidden Devices
i did that but i dont think that will fix the isssue all that does is let me see the hidden one right?

Yes thats the one. I thought maybe the unused entrys in the USB might be interfering with the read on the disk. But I don't have anything to base that on. Just a guess. it won't hurt to clean up the entrys.

how do i clean the entrys ?

The unused entrys will be a slightly different shade. Kind of pale hence "ghost". Right click and select properties if it is a ghost enry it will say it is not present. You can then right click and select uninstall. It will go away.
