What is the primary purpose of using write-blockers?

The primary purpose of using write-blockers is to prevent altering the original evidence. When dealing with digital forensics, it is crucial to maintain the integrity of the original data. Write-blockers serve as a safeguard that allows investigators to access and copy data from a storage device without making any changes to the original contents. This preservation of the original evidence is critical because any alteration, even accidental, can compromise the validity of the evidence in legal contexts and investigations.

Forensic professionals rely on write-blockers to ensure that their findings are reliable and can withstand scrutiny in court, as the chain of custody and integrity of evidence are paramount in digital forensics.
