Why need to wipe partition?

Wiping a partition is a good idea, especially if it contains sensitive or vital data such as bank account details and private information. Regularly wiping a partition can help erase private and sensitive info, but there are other reasons to do so as well, such as freeing up disk space, removing malware, or preparing a partition for reuse.

• Remove the data that you don't need any longer;
• To free up more disk space on the whole hard drive and get rid of the marked unused storage, you can use a disk cleanup tool to remove temporary files, system logs, and other unnecessary data. This will help declutter your hard drive and make more space available for your files and programs.
• Restore the full capacity and repartition the hard disk;
• Eliminate some stubborn malware or viruses.

What is the difference between formatting and wiping a partition?
▸ Formatting a partition simply erases its partition table and removes links to all files, making the entire space writable. The deleted files remain on the drive, marked as deleted, and can still be recovered using file recovery software, especially if new files are written over them. This process does not actually delete the files, but rather makes them inaccessible until recovery software is used.
▸ Wiping a partition involves directly working on the file system level, effectively erasing all data, making it unrecoverable, and allowing for the reuse of the disk with no remnants of the old data.

Notes:

• Fill sectors with Zero: wipe the partition contents by overwriting them with zeros.
• Fill sectors with random data: wipe the partition and overwrite existing contents with random data.
• DoD 5220.22-The process involves three steps: first, overwriting all addressable locations with binary zeroes; secondly, overwriting them with binary ones; and thirdly, overwriting them with a random bit pattern. This ensures that all data is securely erased and cannot be recovered.
• Gutmann: Overwrite the partition with a random character for the first 4 passes and the last 4 passes, and then from pass 5 through pass 31, overwrite with a complex pattern that changes every pass.
