Don't get lost once your hard disk (internal&external) suddenly stops working or not showing up in your computer.

Disk 1 unknown not initialized
How to fix disk unknown not initialized error by diskpart? Is it possible to initialize disk without losing data? As we know diskpart is a Windows command line aiming to change disk properties per the computer usage from users.
The truth - Diskpart would turn the uninitialized disk to a regular disk format (MBR OR GPT) and it is similar as initializing disk under disk management. All data would be erased during the process of diskpart initializing the disk.
Our suggestion - we would recommend you use disk management to initialize disk since it is more simpler and user friendly than diskpart command lines. (The detailed steps of disk initializing with diskpart are included in the end part of this article.)

???How do you initialize disk using diskpart without data loss?
There is no way diskpart could do for initializing old disk without losing files since initializing disk means to start the disk for reuse and everything on the disk would be erased/gone. (Not permanently data overwritten unless you have saved many many files onto the initialized disk)
