Most errors can be divided into two main categories: physical damage or logical corruption are grouped. Physical damage is related to damage the hardware of the drive and logical corruption to the failure of the software associated with the drive. Here are the most common causes of data loss and what, if anything, can be done about it.
Physical damage
There are several types of injuries that may occur, including:
Humiditycontact. Excessive humidity can cause irreparable damage to your hard drive. The best defense is in place to keep your computer in a cool, dry place – away from heating vents or air conditioning. A dehumidifier can be a worthwhile investment if your computer room tends to dampen.

Physical effects. The disc is relatively robust, butis not designed to withstand the significant impact that comes with a drop or hit. The impact can damage internal components of the disk, then the data is unrecoverable.
