We had several unusable computers, full of junk like adware and malware and viruses. We were approached by FreshStart HD to use their data compression software and new hard drive solution to salvage these computers, so we wouldn’t have to buy new ones. We used it on 7 computers from 30gig to over 150gig and each now runs fast smooth — just like new. Probably saved us $ 3000 overall, for just $ 199 I am a huge fan now. highly recommended
