If you have an Xbox 360 console and turn it on to find that you have an E68 error then this article will tell you a bit more about it and the different options that you have to fix it.
Normally the E68 error is caused by a problem with the hard disk drive, and you can test this by turning off your console and removing the drive and then seeing if it runs correctly.
You can also try clearing the cache of the hard drive to do this you just need to enter a series of commands, or button presses. You do not need to worry as this will not delete any of your saved games or anything like that. It will delete the updates that you have done for your games when you insert a disc and the console informs you that it has an update to make, you will need to re update your games but this will be done automatically when you play them again.
All you need to do is go to the system blade and select memory.
Once you've done this press Y on the HD symbol and then press X,X, left bumper, right bumper,X,X once you've done this you will see a blade pop out on the right hand side and it will ask you to confirm that you want to clear the cache.
Select “confirm” and then try restarting the console to see if this has fixed the problem.
If you are still getting the E68 error upon startup then you will need to fix your console and you can do this by either sending it back to Microsoft and waiting a few weeks for another one.
