Why You Need to Securely Wipe an External Hard Drive
Wiping a disk is a process that completely removes all data on a disk, rendering it unrecoverable through traditional or professional data recovery techniques, usually for data security and privacy reasons. For example, when you plan to throw away or sell a used external hard drive, erasing the disk can ensure that the files on it are permanently deleted to prevent personal files or work information from being leaked. In addition, wiping the disk may be to free up disk space. Although most users generally choose to delete files or format partitions to clear disk space, some users prefer to wipe the disk directly.
In conclusion, wiping your hard drive is an important security measure to ensure that your data is not at risk of being compromised. In the next part, we will describe how to wipe a hard drive Windows 11/10/8/7.
