Almost anyone uses external hard drives to save precious data or to extend the storage capacity of their Computer. But like an internal hard drive, they can become unallocated. Without allocation, you are unable to write, read, and store data on the unallocated disk. If you want to access your data on it, you might need to fix the unallocated hard drive and then recover files from the external disk.
Attempting to fix an unallocated external hard drive on it can be difficult but not impossible. Before searching for powerful tools that are specially designed for such occasions, you could try to fix it by using CMD and more specifically "Diskpart". Here are the steps:
Note: This method will erase all data on the external hard drive but it can make it reusable. The good news is that you are still empowered to get the erased data back by using a hard drive data recovery program.
This method might or might not work, depending on what has caused the hard drive to be unallocated.
If you are not sure if your hard disk is unallocated, you can move on to Part 3 to learn what an unallocated hard disk is and what causes a hard disk to be unallocated.
The method above can bring back to life your unallocated external hard drive in most cases, depending on the cause of the issue. However, it also deletes everything on the hard drive and it cannot be recovered afterward.
Luckily, there is another method to recover your valuable data. The software is called Recoverit Data Recovery and it has brought immense improvements in data recovery solutions.
Download and launch Recoverit Data Recovery on your computer, and follow the next steps to recover data from the unallocated external hard drive.
Step 1 Select a data recovery mode. To recover data from external hard drives, you can select the "External Devices Recovery" mode to start.
Step 2 Connect the external disk. Make sure your external hard drive has been connected to and can be detected by the computer.
Step 3 Select a location. Choose the connected external hard drive you wish to recover data from. Click "Start" to scan lost data.
Step 4 Scan the unallocated disk. Recoverit will first launch a quick scan on your unallocated hard drive. You can also go to the "All-Around Recovery" mode to deeply search more files from the hard drive, but it will take more time.
Step 5 Retrieve the lost data. After the scan has been completed, you will be able to preview your files. Select the wanted ones and click "Recover" to get the files back.
When trying to use an external hard drive, after being plugged into the computer, you notice that the drive doesn’t show up in "This PC" (Windows 8 and 10) or "My Computer" (Previous Windows versions). You do a bit of extended search to see what is going on. In Device Manager under "Disk drive," it says that the "Device is working properly". After that, you check in Disk Management and see that the Drive is healthy. However, it also says "Unallocated". This can happen to a single partition. If there is more than one, it can happen to the entire Drive.
Data can be only written, read, and stored in allocated space on a hard drive. Unallocated space, also referred to as free space, is an area where you can't access the stored data and write new data. So if you find the external hard drive unallocated, you should fix it and recover data from the external drive in the least possible time in case all important data present it to get gone forever.
Many reasons can cause this unusual behavior and in many cases, not even an expert can figure out why it happened. Some of the known issues to cause a hard drive to become unallocated include:
Hard drives help us store our most valuable memories. Whenever they fail for various reasons, every picture, work data, and even music collection that have been gathered throughout the years is in danger to be lost forever. Luckily, Recoverit Data Recovery is the exact professional tool to help you recover data from the hard drive so that you can enjoy them forever.
