Although fsck indicates a lot of problems, I think it is not the disk which is malfunctioning. I have run the Maxtor diagnostics over it and that gave 'a certified functioning device', so no bad sectors or anything. But I ran memtest86 afterwards and discovered that two addresses are broken, so that might be the problem. I am going to get it out today and see if everything will work then.
