Hi there. I just registered in order to post here. Yesterday I tried the Data Shredder’s free space cleaner tool, and around the time of “full disk” messages started to pop up, the cleaning got stuck at 93%. I had to stop it and now my 1 tera disk is full when it didn’t even reach the 500 gb. Cannot restore system with windows. I don’t know what to do.
Im such a noob. Please, help me 
What windows version/sp ?
Can you still boot in normal mode ?
windows 7 ultimate/no sp. Yup, the computer works just fine.
Give this util a try:
