Context : I store some sensitive documents on USB drive, and want to protect the data, also it is extremely important that the drive is accessible on all operating systems (linux/mac/windows).
End Goal: Prevent accidental overwrite/format/data-deletion on the USB drive
How can this be done?
If I understand correctly, the only possible way is to block the write command in the USB firmware using "BadUSB" hack tools, but that is only works on certain chipsets (i.e, Phison 2251-03).
Is there any other way to make the USB pen drive write protected? Or is there any existing resource that explains the process on writing the firmware to block the write command (also to burn the same on the device).
Note: I know I should keep backup, and I do, but I would still like the drive to be as tamper-proof as possible.
