Problem scenario: You have a drive "H:" that is using FAT32. You want to conver it to NTFS. You open PowerShell as Administrator. You delete the files on drive H:. You run this command:
convert h: /fs:ntfs
You see this message "File and folder verification is complete." It hangs and never completes.
Solution
Do not use PowerShell. Follow these three steps:
#1 Open a regular (non-PowerShell) command prompt.
#2 Run this command: chkdsk /F h:
#3 Run this command: convert h: /fs:ntfs
