Ok so I have a 250 gb hd slim and it has worked fine up until I haven't played on it in a couple weeks. When I went to get back on it the flippin thing tells me I need an update, so I start the update and it doesn't even get a forth of the way through the stupid update before it errors on me. I've tried to do the update numerous times throughout a period of 5-7 days. I have tried everything from clearing the cache to trying to do a usb update. I downloaded the update to a flash drive and it won't even read my flash drive. I have tried to customize or format it to the 360 on many different occasions and I have tried a portable hard drive all to no success. My 360 won't even read the damn(pardon my language) flash drive nor hard drive. I am at wits end here. All I have to say is I am glad I have my ps3 this is just freakin ridiculous, if I would of known how many issues this system has I would of spent my money on the Playstation Plus account and saved me the headache.
