If you have been using a computer for some time, you probably lived up to the day when your faithful hard drive begins to fault. Depending on the gravity of its errors, here is an overview of what can go wrong and a short guide on how to fix that.
First, and most common type of errors, are errors in the logical structure of your hard drive. They appear when your hard drive was stopped during a reading or writing operation, and there was no time to reflect the change onto the logical disk maps that describe the continuity of information on your hard drive. In such case, a simple disk scan and repair is enough – the system will remove the ‘orphaned’ parts so you can copy them again properly.
