I have an important file on my flash drive and I want to make it read only
My best option is use DISKPART form windows, run this code on CMD
DISKPART
To check which flash drive listed as disk in windows
LIST DISK
It should be disk 1 if you have single hardisk attached to computer, disks naming starts from 0 but partition starts from 1
SELECT DISK 1
Set as read only
ATTRIBUTES DISK SET READONLY
