Every hard drive has a finite amount of storage space. After a period of time, the space on a drive will be filled and no new data can be saved. That’s where in-hard-drive recovery comes in. Read on for more details on how to recover data from a hard drive.
How to Recover Data From Hard Drive?
A hard drive is a storage device inside your computer. It’s what the operating system and applications use to store their files and data. When your computer stops working, the data on the hard drive may be unrecoverable. If this happens to you, you can back up your files to an external drive, or you can have the data recovered by professionals at a data recovery center.
There are several reasons why data is unrecoverable. It could be due to a failed drive, file system damage, or even a software malfunction. Whatever the reason, we’ll walk you through the steps to recover data from a failed drive.
For this tutorial, we used a Samsung 840 Pro SSD as an example. The steps work the same for all hard drives, regardless of make or model.
The first step in any data recovery is knowing the file system used on the drive. This will help you narrow down the correct data recovery software.
“If you have an SSD with a file system that hasn’t been supported in the last three years, you’re out of luck,” says Chris Brantner, CEO of DataRescue. “Just like a car won’t run well because the spark plugs are dirty, the file system on your SSD won’t run well if the last update was more than three years ago.”
If you’re unsure what file system your SSD uses, try to recover data with software that can read the file system. If it can’t, you’ll have to start your data recovery process without that information.
To find out the file system on your drive, open a file explorer and navigate to the drive. Right-click the drive and select Properties. On the General tab, you’ll find the file system listed under “The file system used by Windows is.”
RAID and Solid State Drive Differences
If your computer has two hard drives, you may have noticed that one is much faster than the other. That’s because it’s a RAID 0 array. You’re probably familiar with RAID 0 as a backup method, but RAID 0 is also used for hard drive data protection.
This is the most common RAID level. RAID 0 mirrors data across two drives. Data is written to both drives simultaneously, so if one drive fails, the data is still intact on the other drive. To read data, the hard drive must be replaced with a RAID 0 capable drive. If your computer has a RAID 0 array, both drives must be replaced to recover data.
A RAID 1 array is used for data protection only. It’s a striped set-up where only one drive is critical for the data. If one drive fails, the data is still intact on the other. To read data, the hard drive must be replaced with a RAID 1 capable drive.
If your computer has two or more hard drives installed, one of the keys may be missing (or has been erased). In this case, the drives may be considered “degraded.” Many modern operating systems can automatically encrypt drives, so you may not even know the key is missing.
Some file recovery programs can read these encrypted drives, but the process is complicated and requires the encryption key. If you want to try to recover data from an encrypted drive, you should hire a hard drive data recovery service provider.
You may use software RAID on your computer. In this case, the data recovery process is a little different. Because the drives are connected through a RAID controller, you won’t be able to read the drives without replacing all of them.
