OS: Windows 10, Version 1909 (OS Build 18363.1016) Scenario: With diskpart, I listed, selected, cleaned, and started the format command on a 4TB hard drive. The Diskpart command window showed me a progress by the percentage complete. Problem: For unknown reasons, after about 56% format complete, the Diskpart command-line window closed. Perhaps I had accidentally closed it, but I do not know. The hard drive still appears to be undergoing formatting, but how can tell for sure? Is there a way to check the percentage of formatting complete, similar to what I had seen when the command-line window was open? I had checked all the tabs on Task Manager for some clues, but I could not find anything pertaining to formatting or diskpart therein. I also opened a new Diskpart command-line window, but there was no indication of anything was in progress, failed, or had changed. How do I check the status of having run diskpart commands when the command-line window had closed?
