Storage Issue
After interrupting a download or installation of Adobe some time back, my laptop went high wire, I don't know what really happened to it, at the start it was taking very very long time to Start up, so I was never shutting down my laptop and I managed. Then, it was just not starting. I gave it to one my friends he did something and he managed to get it starting (he advised me to get whatever I want and format it), yet I was lazy to do so. I am not really a heavy user for the laptop I just use for watching movies and series, so I managed somehow. Nowadays, I noticed that I can't do any update and I can't download anything. When I checked the disk utility, it appeared that the available space in my startup disk was actually 0 byte, and if I delete this 0 byte doesn't get affected.
Thereby, could I have any help?
Thanks,
MacBook Pro, Mac OS X (10.7.5)
