Data recovery from unrecognized external hard drive lost data due to not formatted , not recognized , not working ,not showing up, power failure,logical damaged,not detected in bios.

Many times, the external hard drive unrecognized, not the external hard drive is really bad hardware, and even partition and file system are not broken.An old hard drive, like a 50-year-old man in the cold winter to play basketball, he did not hurt, but he needs a long time to do warm-up exercise.

In most cases, this won’t cause any problem, however, sometimes it happens.

In short, if you encounter a similar problem, do not worry, do not rush to dismantle the hard drive to do hardware maintenance treatment, as is very dangerous, like desktop sometimes faulty, you only need to clean the computer dust Can solve the problem without having to spend money to find experts.

When the logic board of a hard disk fails, the drive can often be restored to functioning order and the data recovered by replacing the circuit board with one of an identical hard disk. In the case of read-write head faults, they can be replaced using specialized tools in a dust-free environment. If the disk platters are undamaged, they can be transferred into an identical enclosure and the data can be copied or cloned onto a new drive. In the event of disk-platter failures, disassembly and imaging of the disk platters may be required. For logical damage to file systems, a variety of tools, including fsck on UNIX-like systems and CHKDSK on Windows, can be used for data recovery. Recovery from logical damage can require file carving.

If data loss occurs due to unreadable, not formatted , not recognized , not working ,not showing up, power failure,logical damaged,not detected in bios, a successful recovery must ensure that the deleted data is not over-written. For this reason — one should avoid all write operations to the affected storage device. This includes not starting the system to which the affected device is connected.
