A small script to automate toggling read-only mode independently of partiton letter or drive 'rank'.

This was inspired by the fact that most malware cannot override read-only mode because of the high required administrative privileges unless the whole system is taken-down already.

Disclaimer: This script is provided "AS IS", without any warranties and should be used at your own risk.

cd to your removable drive

PS X:> cd X

git clone this repository

PS X:> git clone https://github.com/Yiidiir/removable-read-only.git

cd to removable-read-only/examples

PS X:> cd removable-read-only/examples

PowerShell must have elevated privileges (Administrator) to access Set-disk -IsReadOnly

PS X:> .\read_only.ps1
usage: .\read_only.ps1 [-write] (BOOLEAN)

Set removable drive to read-only mode

required argument:
  -write            Allow writing in drive (must be explicitly declared)

The only existing input is a boolean declaring whenever writing should be allowed or not:

PS X:> .\read_only.ps1 -write 0

By default there will be no output.

PS X:\>

If you want to see a an output message, uncomment lines: 8,12,3 from read_only.ps1
