Some useful methods for recovering your deleted data from hard disk

Our hard disk stores a large quantities of important data. The loss of these data may bring  us immeasurable loss. To reduce the risk of data missing, we should know some common knowledge bout data recovery from hard disk.

　　1.The two categories of hard drive failure may cause your data loss.

　　Physical failure

Physical failures are often due to  a head crash and/or motor failure. If your hard drive is not working or is making clicking or grinding noise, it is experiencing a mechanical failure. You need hardware recovery.

　　Logical failure

　　When you experience a logical failures , you cannot perform the operating system and are not able to access the data on your drive disk. And the files even cannot be opened by associated application. Some files and folders, partitions will be missing.

But don’t worry.  The data can be retrieved as long as the data area are not completely covered. In most cases of logical failure, a hard drive recovery software can successfully help you to restore data.

　　2. Cannot find the program after restart your computer from a suddenly switched off.

　　When the computer suddenly  loses power , you restarted the computer. And booting the computer can detect the hard disk but you are not able to enter the system.

　　That may be the main boot partition failure. It accounts for more than 30 percent of logical failure. In this failure, the computer will hints” Miss operation system” after the computer performed a SELF TEST. And you can read all the data on disk c in Disk Operating System.

In that case, you can use the floppy disk bootable system. Type “C” to see  if can read the content on the c disk. If  you can, then you can run Fdisk/mbr  to rewriting the main boot partition unconditionally. That is possible for you to save your original data.

　　3. Data losing from using PQ Magic

Problem:   Re-partition or merge partition by using partitioning software result in file loss or the file cannot be opened. That is caused by  Error reading partition table. The failure of Error reading partition table is very common. So you need a data recovery software to help recover.

　　4. Cannot open a partition. The screen prompts you that the partition has not been formatted.

Problem; The drive letter cannot be opened in using, and it prompts that “ This partition is not formatted!” You just need to reformat if there are no very important files in this partition. But if there are important data, you need to find another computer. And put the damaged hard disk on this computer to see if you can open the partition. If still not, we have no other solutions.

　　5. Track 0 Bad, Disk Unusable

　　The Track 0 is most important for computer. I t contains all the disk partition table. Once the track 0 is damaged, you cannot start the drive disk.

　　In conclude, there are many kinds of data loss for drive disk. Please do not do it by yourself before you have understand all above. If you still have trouble in recover your data from hard disk, please do not hesitate to ask Hdata recovery technical team for help.
