Hard Drive Failures Can Be Devastating For Data Recovery

In computer sciences, data recovery is an efficient process of restoring inaccessible, lost, corrupt, damaged, formatted or unreadable data from removable media, computers or other devices, when the data contained in them can’t be accessed in an ordinary fashion. Data recovery techniques are very important for all forms of data loss, whether from physical processes such as hard drive crashes, viruses, Trojans and other malicious programs, human error and accidental deletion or even accidental deletion by the user. It is also helpful for backing up data and recovering information in the case of computer crashes, virus attacks and system failure. The process helps to restore data that has been mistakenly deleted or lost.

Data Recovery

Data recovery techniques include various methods for taking apart and putting together again. The technique is used in order to find out the cause of the problem and then fix it. There are two types of data recovery, one involves putting the data back on the same drive that it was lost on. The second requires rebuilding the drive from scratch. The second is not so difficult as the first, and is thus popular.

The first method of data recovery techniques is to find out where the problem originated from. It can be divided into logical and physical data recovery. Logical data recovery techniques involve checking the drive’s SMART status. SMART stands for random access memory. This indicates how fast the drive is able to read and write information, and hence how much damaged it would be if the drive is totally written out.

Physical data recovery methods include physically taking apart the storage media. Most of the time, the media will have incurred physical damage, either through physical tear or mechanical damage. These media include CD-R, DVD-R, floppy disks, network drives, USB drives and others. After physically taking apart the media, you should check the area where the data recovery requires to be done.

The first step is to check if the damaged drive uses a file system format. It is very often the case that data recovery software will not work on a file system format. So in this case, you have to check the physical media. If you cannot see any difference, the file system format must have been damaged, and you should try another data recovery method.

Apart from checking the physical media, the other important thing to check is the storage media. It is important to know what happened to cause the hard drive failure. It could be due to physical damage or a logical failure. To get a quick idea of the condition of your storage media, take a look at the last time you attempted to save some important files using it.

This can give you an idea of what happens when you are trying to make a backup and recovery process. Some of the physical drives might not suffer from any problem but the performance of the drives can be seriously affected. Most data recovery software programs come with several different types of backups. If some of the important files are not recovered from the drives, the backup program can be adjusted.

When you find that the physical media and the storage media are working fine, you can test the hard disk recovery software. You can simply open the program and then run a disk test. This tool checks to see how many times the drive has been written to and read from. If the percentage is less than 95%, the data recovery software tool can be adjusted accordingly. Usually it is better to use full backup instead of partial backup, otherwise you will be wasting time in trying to recover a small part only.
