How to Recover Data from a Hard Drive

Hard drives fail all the time, especially in storage environments where they have to go through hundreds of reading and writing cycles every day. If you’re working with a disk that has failed, you’re probably wondering what can be done to get back the data that’s on it.

Hard drives are susceptible to many different kinds of failure, and trying to get data off of a failing drive can be a difficult process. There are many different reasons why a drive might fail, but with a bit of research and preparation, you can often recover data that was on the drive.

What is a “Hard Drive”?

A hard drive is a type of storage device that contains and stores information on rotating platters. They’re typically made of metal, plastic, or glass and are very durable. The amount of data you can store in a hard drive can be measured by the frequency at which it spins and read/write speeds.

How to Recover Data from a Hard Drive

Hard drives are made of multiple platters that spin around an axis, and the heads read data from different areas of the platter. If a hard drive fails, it means that one or more of these components stopped functioning properly. This can be due to physical damage, such as a head crash or improper handling that caused the read/write heads to deform and become unreadable. If you want to recover data from a failing hard drive, you’ll need to remove any head crashes or improperly-positioned read/write heads, use specialized software to run tests on the platters and read/write heads, and then use magnetic force microscopy (MFM) imaging techniques to look at which sectors on the platters are damaged.

How Do Hard Drives Fail?

Hard drives fail for a variety of reasons. One of the most common is that the disk may have been dropped, causing damage to one or more platters. Hard drives can also suffer from corruption caused by power surges and heat. Another common cause of failure is a hardware malfunction, which means even if you’ve taken extra precautions, you could still lose your data.

Make the Drive readable before recovery

If your drive has failed, you’re going to need to take a few steps before recovering the data. To start, make sure the drive is readable before you attempt the process. This can be done by disconnecting it from power and isolating it from any other devices.

Once you have made the drive readable, you can then move on to trying to recover the data. One of the most common methods is using a data recovery software program like Recuva or Stellar Phoenix Data Recovery. You will just need to find a way to transfer files onto another disk before attempting recovery on that disk.

The RAID recovery method

The software RAID recovery method is a way to recover lost data from a failing hard drive. This can be done by using specialized software, which reads the sector information in the bad sectors and tries to find any data that has been stored in those sectors.

This option is often used for recovering data from drives that don’t have any physical backup copies of the files. You’ll need a computer with an operating system like Windows or macOS and enough free space on it to run the program. It will scan your drive for bad sectors and then try to read the content from them. If you do this well enough, you might be able to get all of your data back.

How to Recover Data using footage

If you suspect that your drive has failed or is about to fail, try the following methods for recovering data. First, if possible, make a backup of the hard drive. If you don’t have a backup, try another method listed below before making the effort to recover data from a failing drive. Next, if possible, save all of your files to a separate external device, like a thumb drive or an external hard drive. Finally, try using software tools to extract the data from inside the disk. This might be a long shot because it will take time and careful work with software tools to extract any usable files from the disk.


If your hard drive fails, it’s best to recover data from a drive before it becomes too corrupted to be read. The software RAID recovery method is an easy way to retrieve the data from a failed hard drive. Remember, the most important thing that you can do for your data is backup.
