How to fix "external hard drive not intilized" in Windows 11, 10, 8, 7?

This error is possibly caused by the connection problem. You can use another cable to connect the external drive. If possible, connect it to another working computer.
Solution 3. Fix MBR for the external hard drive
If MBR (master boot record) of the hard drive is corrupted, Windows cannot access the data on the drive. In that case, you will see the external drive "Disk unknown, not initialized, unallocated".

If your hard drive is infected, it will continuously write data to it and prevent other programs from accessing it. Therefore, the external hard drive may show as not initialized or unable to initialize in Windows 11, 10, 8, 7. You can use Windows Defender or third-party anti-virus software to do a full scan of your computer.

5. Then use Disk Management to initialize the disk, which is more simple and clear. Of cause, you can also initialize disk with DiskPart.
Solution 6. Diagnose the external hard drive
If after all these steps and you still cannot initialize your external hard drive, it is possibly because the drive has some bad sectors or it is physically broken. You can run a Disk Surface Test with Qiling Disk Master.
Step 1. In the main interface. Click on the external hard drive and select the "Disk management" tab page. Then select "Surface Test".
