Well the main problem is that when i start my laptop it goes to the starting windows screen, doesn't go pass that, then just always goes to startup repair, which never fixes anything. I tried a solution found on these forums but didnt work, so i was trying to take my files out but it gave the I/O error, which I also got when trying to fix my laptop. The size of the folders i am not sure, because when ever i open any of them it says I/O error. As well all my folders are empty. I was going to re install windows 7, but i stopped because it showed my hard drive stilled had my files, so i stopped, to try and get my files.
