“Hi. I have the same problem. When i plug in the drive, it says that it’s successfully installed however it does not appear in ‘my computer’. Also when i go into system tools it says that disk 1 is unknown, not initialized, unallocated. Can you please help me, I don’t want to lose my data, it contains all my pics. Please help.” – said by jenny123 at SevenForums
Obviously, all partitions and data on the external hard drive of jenny123 are missing now. And what he wants to do now is to recover files from unallocated space. He just has no way to achieve this right now. In this case, we feel it’s necessary to recommend MiniTool Power Data Recovery to users who have similar problems. Definitely, it’s a wonderful tool for unallocated hard drive recovery. If you doubt about it, please read the following proofs.
Step-by-step Tutorial on Unallocated Hard Drive Recovery
When you realize that your hard disk becomes unallocated and is not shown in Windows Explorer (or “my computer” as the user said), please open Disk Management and you’ll be able to see the status of that disk.
From above picture, you can see disk 1 is an unallocated disk with no partitions on it. And we can find no other problems from this. So if you just need the data back, you could launch MiniTool Power Data Recovery right now (if you don’t have one, please download it from reliable site). Then, start data recovery and partition recovery from unallocated space officially:
Step 1: choose “Lost Partition Recovery” from main window; then, select the unallocated drive and press “Full Scan” to search for files in above interface.
Step 2: look through all partitions to see whether the files you needed are found by software or not; if you failed to find some files you need, you may click “Back” button to show other possible partitions found by the software (since MiniTool Power Data Recovery may not list all found partitions in the last recovery interface).
Step 3: choose all the files you want to recover and press “Save” to recover them to a safe location.
After that, if you would like to recover unallocated partition/partitions, you could use MiniTool Partition Wizard to perform Partition Recovery Wizard or just to create new partitions on the target disk.
See, it’s so easy to complete unallocated hard drive recovery as long as you have this tool.
