Corrupt hard drive recovery Cheap hard drive recovery

Hard drive failure has been a big problem threatening data security. To recover data from hard drive, you should know more about hard drive failure.

Hard drive might be damaged for many factors like harmful virus infections, hardware failure, software failure, file system corruption, partition table corruption, partition errors, bad sectors and so on. Symptoms of a corrupted hard disk are listed below:

1. Windows showing “The disk E is not formatted. Do you want to format it now?”
2. Hard drive run very slowly and have a strange noise like clicking, grinding
3. The screen show s that “Sector not found”
4. When you boot computer, it shows many error messages on screen
5. File system displayed as “RAW” and many other unusual behavior
6. Automatic execution of Chkdsk command on start up
7. Corrupted data: You cannot open or save any file

The common hardware failures:

1. Hard drive circuit boards damage

The power failure  of hard disk, or a computer poor quality circuit board may lead to burning out the circuit board and breakdown of the chips.

Circuit boards the failures are generally as follows:

1.A power supply failure.

If there is a problem in power supply circuit of hard drive, the hard disk can not work. The performance can be no power, can not detect hard disk,  the disc does not rotate, the head does not seek. Parts of the power supply circuit often have problems: the socket terminal, filter capacitors, diodes, transistors, and insurance resistors.

2.Interface failure.

If the interface circuit fails, it may lead to a hard disk can not be detected, messy code, parameters misidentification etc. Parts of the interface failure are usually interface chip and its matching crystal, broken interface pins, empty solder interfaces, interfaces exclusion damage and so on.

3.Cache fault.

Caching is used to speed up the hard disk data transmission. If there is a problem, it may lead to the hard disk cannot been recognized,  appearing messy code and abnormal crash.

4.  BIOS failure.

BIOS is used to save parameters such as hard disk capacity, interface information etc. All the hard work processes are related with BIOS . The moment of electricity on off may lead to the loss or chaos of BIOS program. If BIOS is abnormal, the hard drive can not recognize.

2.Hard disk bad track

The long time using of hard disk, improper shutdown or sudden power loss may lead to bad tracks and the data cannot be read. The causes for bad tracks can be your abnormal shut-down,static electricity, overheating, dust.

In these cases, your hard disk may have a bad track.

1. You open a file or run a program, the hard disk load and repeated error.
2. The sound of disk is quite strange.
3. The progress bar has stalled when you format the disk. Finally it report error and cannot finish format.
4. The system will automatic perform scandisk scanning program.
5. When you perform Fdisk, the progress bar will back and forth so that you cannot complete scanning.

Maintenance skills for hard drive

1. Keep the computer in a clean environment
2. Form a good habit to correctly turn off your computer.
3.  Prevent it from high temperature, moisture, and electromagnetic interference.
4. Avoid shocks when you move hard disk.
5. Regularly defragment the hard disk.
6. Notice the prevention of the virus.
7. Hard disk bad tracks.
8. Do not use the hard disk compression.

If your hard drive is not physically damaged, you can use the data recovery software to retrieve your data. It can recovery your data lost from virus infection, accident deletion, formatted drive, lost partition; and all kinds of files like video, image, music, documents etc.
