Description

"Thumbscrew is my attempt at a poor man's USB write blocker. When used it allows you to quickly enable or disable writing to all USB mass storage devices on your Windows system. In other words, you can use it to make a USB flash drive, hard drive or IDE / SATA drive in an enclosure read only. However, I make no guarantees as to its forensic validity. Still, if your poor and you want to play around with making forensic images of thumb drives and other USB mass storage devices it may come in handy." - Thumbscrew: Software USB Write Blocker (irongeek.com)
