Can't format external USB drive.
I am trying to format 2 partitions on an external 1TB USB3 drive. I had 2 ExFat partitions (partitions 6 and 7) which I have deleted and created 2 new ones using diskpart which I want to format NTFS.
When I try to format them using disk management it hangs, explorer crashes and I have to hard power off.
When I try diskpart I get the error "The parameter is incorrect. See the System Event Log for more information.". There is nothing to be seen at all in the system log.
Have I created the partition table incorrectly in some way? It was originally created manually using this utility GPT fdisk | SourceForge.net
The other partitions are working fine.
