Final answer:
When creating a forensic copy, it's important to ensure no changes are made to the source drive. Write-blocking tools, such as hardware write blockers, help prevent any data from being written to the source drive. Other measures like making a bit-by-bit copy or using forensic software can also protect the source drive during the process.
Step-by-step explanation:
Forensic Copies in Computers and Technology
When creating a forensic copy, it is important to ensure that no changes are made to the source drive. This is typically done by using a process called write-blocking, where a hardware or software tool is used to prevent any write commands from being sent to the source drive. The purpose of this is to maintain the integrity of the original data and preserve it for analysis.
One common example of a write-blocking tool is a hardware write blocker, which is a device that sits between the source drive and the forensic computer and intercepts any write commands. It is designed to be tamper-proof and ensure that no data can be written to the source drive, thus preventing any changes from occurring.
In addition to write-blocking, other measures can also be taken to ensure the preservation of the source drive, such as making a bit-by-bit copy of the drive or using forensic software that creates read-only access to the source drive. These methods further protect the source drive from any accidental modifications or alterations during the forensic copy process.
