Can data from external hard drive be recovered?

External hard drives are often used on Windows systems to expand home computers' storage space. They are a fabulous alternative for storing personal data that you don’t want to be on your computer's hard disk drive. Data is also shared effortlessly on an external hard drive with others.

Many people save data on an external device and want to store it for future use. However, the external drive can sometimes be damaged or corrupted for various reasons, which can put your data at risk of data loss, like other storage devices.

Some cases are quickly addressed to get lost data recovered. Do you know if data from external hard drive can be recovered? The answer is yes. It's easy to recover external hard drive data with available backup files or data recovery tools. 

What causes data loss on an external hard drive?

The following factors may result in corrupted or damaged external hard drives: file transfer interruption, virus or malware infection, read & write head crash, corrupted file and file system, etc. 

There is a list of common challenging disk problems and the types of damage they cause. You can use this list to decide whether you can try to retrieve lost data by yourself or contact a recovery service if your external hard drive gets dead due to physical reasons.

✪ Accidental file deletion: This kind of logical damage usually does not lead to a dead hard drive. If you take action fast, data can typically be retrieved using operating system capabilities or applications for data recovery.

✪ Formatted or reformatted external hard disk--If you format your Western Digital or Samsung external hard drives mistakenly, the contents that contained it effectively have caused logical damage. Fortunately, data recovery software can help you retrieve data from the formatted drive or partition. The important thing is to stop using the drive until you have recovered.

✪ Corrupted files and files systems-- A corrupted files system is a type of logical damage that can stop your external hard drive from operating. File system corruption may result in a crashed drive not allowing you to boot your computer. Data recovery software can work this type of problem out.

✪ Mechanical damage—Internal parts of hard drives move at high speed and can be less reliable as they age. Read/write heads on a hard drive hover over the surface of the platters that store your information, and data loss may happen if they contact the platter. Other typical physical defects include interior wear and abrasion of the plates:
-The spindle locks up, which controls the hard drive's spinning.
-Actuator arms do not work correctly.
-Noises from the read/write head faults, clicking or beeping on the drive.
This type of damage often causes your system's failure to recognize the device. If your system cannot recognize the drive, you will have to restore your data with a recovery service.

✪ Power surges-- A power spike may damage your external hard drive and lead to a broken storage device requiring data recovery software to restore data. The drive seems dead after being exposed to an intense power spike.

If your external hard drive is logically damaged or corrupted, there are methods to help you to get data back. However, if it is caused by mechanical or physical damage, it may work to send the disk to the nearest tech support company.

Is It possible to recover Data from a dead external hard drive?

The first thing is to define whether an external hard drive is dead. An external hard disk, for example, is not detectable; it can produce noises; it answers too slowly, or it cannot respond at all. It is impossible to declare with certainty that it is dead in all these situations, but it can be asserted.

In other words, you should try to get off the data on the external hard drive first because there is a possibility of data loss. If you could recover lost data via data recovery software, your drive wasn't dead, only temporarily stunned in this scenario.

The scenario is different if the disk is ejected and your operating system cannot identify the drive after that. Send the drive to the nearest technology supporter if you have almost no choice of using a professional data recovery service to restore your data. They should be helpful.
