HELP: I was installing windows and i was cleaning local disk C partition.After cleaning,I saw that the whole hard disk got cleaned and it was written there "Unallocated space 498 gb of 500 gb". Can the data be recovered.It is very important for me.Thanks
So you had a drive with data on it?
And then you installed an OS on it, wiping the entire drive while you did this install?
And now you want the original data back?
1. This is unlikely to actually work. Most of it has actually been overwritten.
2. You'll need a whole other PC to maybe try this.
3. Possibly a partition recovery application.

I wouldn't count on success, though.
