Nationwide data recovery can be somewhat expensive if you want them to save your whole hard drive, but this is just in case it is a hardware failure. If this is the case, please contact one of the many nationwide data recovery centers. The advertisements on this site might be able to help you there.
Using PC backup software that stores your data online and having a healthy hard drive can save your day. Nationwide data recovery costs can be several thousands of dollars while having all your data stores online and having an extra spare hard drive in case of total meltdown will cost close to nothing. If your computer is stroke by lightning or your hard drive break (yes, it can break, it is mechanical and full of moving parts) you can easily replace your hard drive and download your stored data from the internet backup service. It is even possible to make a backup several times per day with a scheduled backup script. I will cover this later.
