Spoiler — It’s cheaper than buying one I was looking to buy a write blocker to do data recovery/forensics tasks but I quickly noticed that I was window shopping write blockers due to their cost. Some starting at £300, others that cost less were no longer being built or sold, maybe you could find a 2nd hand one with or without the wires. Most of these write blockers were industry standard, used by law enforcement but was it necessary for me to buy such an expensive write blocker….or is it possible to build my own….. So th e research began, reading through articles, publications, and so on, and with the information gained, I felt that I could build my own write blocker. So what do I need: A Raspberry Pi A Linux distro. HDD/SSD to test the write blocker And to put the information I gained into practice Building the write blocker So, I brought a Raspberry Pi 4 Model B that came with a power supply, HDMI cables, 32GB SD card, a case, and some extras.
