What Causes Format Option Greyed Out and SSD Not Formatting

You will encounter the “Format option greyed out” error in two cases. One is that you choose the C drive (system partition) to format, while the other is that the selected volume is corrupted. Generally speaking, you are not allowed to format the C drive on all Windows operating systems unless you would like to reinstall the OS.

Given that fact, you will receive the “Format option greyed out Windows 10” error after right-clicking the C drive. The issue also appears when the chosen volume is corrupted due to virus infection or bad sectors. To get rid of the “Format option greyed out” error, you should choose a non-system drive to format. Besides, you can run a virus scan or hard drive test to ensure the target drive is not corrupted.

SSD won’t format in Disk Management when the “Format option greyed out” issue appears. At this time, you can use Disk Management alternatives like File Explorer and Diskpart to format the SSD. However, if there’s something wrong with the SSD itself, you are unable to format it too.

  • The inserted SSD is write-protected.
  • The hard drive is corrupted.
  • There are malware attacks on the SSD.
