How to Fix an Uninitialized Disk Cannot Be Scanned by Recovery Software?

Because your disk has a CRC error and many recovery software programs fail to scan for your lost data, you can clone your unknown, uninitialized disk to another usable disk. Then, use professional iBoysoft Data Recovery Software to search for your data on the usable disk. After that, you can re-initialize the corrupted disk for future storage needs.

But, before we begin any complex operations, let's double-check the connection between the disk and your PC. You may insert the disk into another device or simply switch USB ports. If the disk appears normally, everything is fine. While it still appears unknown, uninitialized, and with 1TB unassigned. Try the complex solutions listed below.

Clone your unknown, uninitialized, 1TB no assigned disk to another external hard drive, and then run iBoysoft Data Recovery Software to scan for lost data.

Step 1: Download and install iBoysoft Data Recovery for Windows on your PC.

Step 2: Connect the uninitialized disk to your Windows computer as an external drive.

Step 3: Launch the recovery tool and select the Data Recovery module in the home window.  

Step 4: Click "Find More Partitions" at the bottom, then select the hard disk and click Next to scan lost partitions.

Step 5: Select the lost partition and click Next to extract data.

Step 6: After scanning, lost files will be listed. Right-click the found files to tap the Preview option to see if the found files are intact.          

Step 7: Select the needed files and click Recover to start recovery.

Step 8: After the recovery process ends, please save the lost data to another disk.

With all your data back, you can deal with the corrupted disk then. Here are simple instructions on how to re-initialize it on your PC.

Step 1: Right-click My Computer and Select Manage, then locate and open Disk Management.

Step 2: Right-click the disk and then click the Initialize Disk option.

Step 3: Select MBR partition style (Master Boot Record) and then click the OK button.

Step 4: Select and right-click the unallocated space on the drive and then select New Simple Volume.

Step 5: Select Next, specify the size of the volume, and then select Next.

Step 6: Specify the drive letter that you want to assign to the volume and then select Next.

Step 7: Specify the file system you want to use (usually NTFS), select Next, and then click Finish.

After the initialization process, go to This PC or Disk Management to check if the hard drive is fixed.
