How to Use a Write Blocker During a Forensic Investigation

There are a number of advantages to a software write blocker, such as the fact that it does not rely on an underlying operating system or software-based subsystem. One downside of this device is that it needs an external adapter, which negates one of its benefits. Another drawback is that it can be difficult to explain to non-technical people. Using this device also requires that you understand the mechanism it uses to prevent data writes.

In some cases, a write blocker can be a great help when examining images and videos. However, there are also cases in which it may not be able to do so. This is when forensic examiners have to use an external hard drive. If the hard drive was tampered with, the forensic examiner must use a write blocker to prevent tampering. The mere act of plugging in the hard drive can change its contents, making it unusable as electronic evidence.Regardless of whether a write blocker is software or hardware, its use during a forensic investigation is essential. These tools help ensure that no one else can alter the original image. Forensic investigators can examine the computer of a suspect without the worry of losing any evidence. A write blocker is an essential piece of equipment to prevent data theft and unauthorized access. It is the perfect tool to use when investigating the integrity of a suspect’s computer.
