Hard Errors and Soft Errors There are two kinds of errors that can affect the data on your hard drive hard and soft. Hard errors are caused by a hardware problem that affects the data. The most common reason for this kind of error is a physical error on the hard drive platters the part where data is written to . These errors can mean the data either wasn t written to the platter properly or that an area on the platter has become unreadable since the data was written. Either way your data is lost and the chances of recovery by using software are determined by the scope of the damage what part of the data was damaged and how big the damaged area is. Recovery might be possible if you send your drive to a company specializing in data recovery but that is likely to be costly. Hard drives showing any signs of hard errors need to be replaced with the utmost urgency. These kinds of damage do not get any better over time only worse. FIX-IT-YOURSELF HOME REMEDY The .
