Physical Damage
Physical damage means the corruption to the physical parts of the storage devices. There are a number of possibilities such as the improper working of hard drive due to the technical failure like head crashes, motor fail or improper power supply. Tape drives can generally break when kept in the bag while traveling and CD ROM drives can get their layers scratched off are some common reasons that most probably happens and cause data loss. Physical storage media damage always causes some type of logical damage as well as there are some clusters shattered which are inaccessible.
You should always keep in mind that you can not repair the physically damaged disks by yourself because it may cause more damage. There are two common reasons because of them you can not open it yourself:
• If you open the drive in general room can more damage because it leads to dust resolution on the surface on the drive.
• You are not trained for that and you may not have proper equipments required to open a disk.
To overcome these problems, you should consult data recovery service provider companies. These companies provide the facility of a maintained data recovery lab called “Clean Room” and also have the experienced and professional data recovery associates. If any kind of logical damage is also exist with the drive then these companies recover data from it also. Data recovery services are same for all kind of hard drive, no matter what is the operating system and file system used.
Logical Damage
The Logical damages happen more commonly as compared to that of Physical damage. This is mainly caused due to improper maintenance where the file systems are prevented from being entirely written to the storage media. This may result in the variation in the state of the file system and can cause many problems such as operating system corruption and system boot error. Logical damage may also happen due to the virus attack. These reasons may cause actual data loss.
If these situations are occurred up to a limited stage, then these may be repaired with the inbuilt operating system utilities. These system utilities include Chkdsk in Microsoft Windows and cdisk in Linux.
If these general system utilities are failed to recover your lost data, you may use special data recovery software. These software are designed to recover data from corrupted or damaged storage media. You may also recover the deleted data with the help of these software. These software are divided into different categories according to the Operating system and file system of the particular operating system.
