I want to password-protect write and format operations of a USB Flash drive but also want to access the USB Drive with read-only access without any password. How can I achieve this?
As far as I know, you can't achieve that. You could:
- Encrypt your whole drive with VeraCrypt.
Encrypt your flash drive gives you protection but you need to input the password in read/write operations which doesn't suits your needs.
- Have a flash-drive with a physical read-only switch
This offers what you want but because it's a physical switch it will be easy to override read-only protection (and of course it isn't a password method).
