I was using DiskPart to set the readonly attribute on my USB flash drive. I used the command
select disk 1 //disk 1 is my flashdrive attributes disk set readonly detail disk
On executing detail disk it showed the readonly and current readonly state as Yes.
Now I plugged this drive on another PC and ran the detail disk command on DiskPart but now it shows the status of readonly and current readonly state as NO.
Why is this happening? It seems as if setting readonly flag on a PC does not change anything on the drive itself.
