When i plug my xbox 360 hard drive in it makes the screen go blank?

Microsoft has shipped numerous variations of the Xbox 360, with the major difference between each one being the hard drive size. As a result, your Xbox 360 can have a hard drive size as low as 4 GB and as high as 250 GB. If you're unsure of the size of your Xbox 360's hard drive, or just want to see how much space is remaining on it, you can check from the Device Options screen. This screen is accessible from the Xbox 360 dashboard when using any Gamertag.
Step 1 Select the "Settings" tab from your Xbox 360's dashboard.
Step 2 Select "System" and select "Storage" from the onscreen list.
Step 3 Highlight your hard drive from the onscreen list. By default the name of the hard drive is "Hard Drive."
Step 4 Press "Y" on the Xbox 360 controller to access the Device Options screen. The right side of the screen lists both the overall size of your hard drive under "Capacity" and the remaining amount of space under "Free Space."

Tip

• From the Device Options screen you can also give your hard drive a custom name, clear the system cache or transfer content to another memory device.

In this process your hard drive will be formatted, so back up all files to another hard drive, laptop, or be prepared to lose everything on your hard drive. After you have backed everything up, plug your hard drive into an Xbox 360 then go 'My Xbox/System Settings/Memory.Select 'USB Storage Device/Configure Now' then accept the warning.After the formatting is complete a Performance Warning box will appear, click 'OK.' Now in the 'Storage Devices' screen you should see a new option 'Memory Unit.' This shows that the formatting was successful. Disconnect your hard drive, then connect it to your laptop, load on some media (makes sure the file types are compatible), then reconnect it to your Xbox 360. Your selected media should not appear under 'Portable Device' in the Video/Music/Picture Library.

Try reformatting it on a MacBook through disc utility if that doesn\'t work try formatting it in system info or disc management on windows

If you get the Xbox 360 1 red light message, it means that the problem is either with the DVD drive, or with the hard drive.

Fortunately, the Xbox 360 1 red light message is not something that you should worry about. In order to identify which of the two drives the Xbox 360 1 red light messages is referring to, just look the code number that the screen displays. DVD drive errors are identified with the codes E64, E65 and E66, whereas hard drive errors are identified with codes E67, E69 and E79.

Once you identify which error the Xbox 360 1 red light message is pointing to, fixing it is really easy. The guide available at Fix-xbox360.info will tell you what to do in each case, as well as what to do in case you get any of the other Xbox 360 lights messages. Check it out.

Your problem is the hard drive is formatted as "NTFS". Dont worry its not complicated. All I am talking about is the method in which the hard drive stores data.

Your Hard Drive needs to be "FAT32".

PLEASE SAVE ALL YOUR FILES OFF OF THE HARD DRIVE

Right click My Computer - > Manage - > Select Disk Management under Storage.

Here you can remove the NTFS partition and recreate it using FAT32.

When you go into Disk Management, right click the partition and choose Delete Partition. Make sure its ont he right Hard Drive! Double check. Then right click in the blank space and choose Create New Partition (I think that's it). Then right click the new partition and choose Format. Select Fat32 for File System. At that point you should be done.

You must have a memory card or harddrive plugged into the Xbox 360 for the update. Please note that the update might not fit on the memory card

Without the code the only thing to do is buy a transfer cable from eBay copy all of your stuff and then format the drive plug the drive back into the 360 let it set it up then go back to your computer and copy your stuff back on.

try this. unplug everything (power cord, av cables, wireless adapter, controllers) and take off the hard drive. dont plug anything in for about 1-2 minutes. when the time is up, put the hard drive on first then plug everything else in.
