Have you ever tested your hardware write-blocker?
The CRU has developed the Write-Blocking Validation Utility. It provides an easy-to-use method to determine if a hardware write-blocker blocks low-level hard drive commands.
The most important thing – it is free! And also extremely easy to use – just connect a drive and perform the validation test.
The utility can be used with any brand or model of write-blocker. Want to give it a try? Download it here.
