Hewlett Packard -- We Tried to refresh One of their machines and HP created Partitions on the hard drive which we cannot move or delete. Now our machine has only an available 100GB of space we can use, out of 750 GB on the machine. We called to ask how to fix it and since they caused the problem they should fix it. All they did was try to sell me tech support for a problem caused by them, I now understand why You should never purchase Hewlett Packard--My Acer never gave me a problem like this. I will never purchase another item from them.because youwill not help us fix the problem caused by you allocating partitions on the hard drive when we refreshed I will make sure never to promote your product or business
