I've been searching for a while and can't find anything about this.

I'm using the 120GB HDD that came with my 360, but today it has just stopped working altogether.

It can still save data, view saves in the memory tab and sign in to any profile stored on it.

However, it can not load ANYTHING at all, not the themes, very rarely do any avatars outside of my own appear, (Which even then is stored on my memory card.) save games, arcade games... Things that do load up are very slow, such as the list of games+achievements.

Basically it's screwed, and I come on here hoping that somebody has a solution to this, anybody? Please?
