In Windows, when you add new hard drive, you must initialize the disk before you can use. Initialization process configure the newly added disk with partition style such as Master Boot Record (MBR) or GUID Partition Table (GPT). The MBR partition is usually recommended, in case if you’ve to later use the disk with previous versions of Windows. As soon as you add the new disk and start Disk Management snap-in, you’ll be automatically asked to initialize the disk.
However, recently we came around the issue where we were not able to initialize the disk. In this case, we were not asked to initialize disk after opening Disk Management. Also, when we right click on the disk, Initialize disk option was greyed out (refer below shown screenshot). In short, we’ve no way now to initialize the disk.

FIX 2 – Replace The Faulty Disk
Usually, if the disk is still not ready to initialization, you must plug it to another machine and check if it works on that. In case, if you receive same result on another machine, the disk might have hardware fault. You must contact the hard disk vendor for support on this or ask them to replace the disk, in case if it is under warranty.
Hope this helps!
