Initializing disk is a process of building or rebuilding MBR (Master Boot Record), the first sector of a hard drive, which stores information to load logical partitions, even system files on it if there are.
During the disk initialization process, the Disk Management or third-party tool will write or rewrite the 0 sectors in the MBR partition table. However, only initializing the disk won't make it usable again. You need to further partition and format the drive.
Typically, Windows will ask you to initialize the disk in the following two situations. And there is no data loss if you initialize a new disk. But if the disk becomes not initialized suddenly, you will lose your data, as you need to partition and format the disk after initializing. If you don't partition the disk after initializing, you cannot use it for storage.
#1: You install a brand new disk on the current computer and doesn't show up in File Explorer.
#2: Your old disk shows "Unknown, Not Initialized" suddenly.
