In the process of using storage devices, we often encounter situations where previously created arrays and partitions on a disk no longer meet current requirements. To reconfigure arrays and partitions based on new needs, it is necessary to delete existing arrays, partitions, and even superblocks on the disk. Failure to do so may lead to various obstacles when creating new partitions.
In such cases, disk wiping is required to thoroughly remove all records on the disk, essentially performing an initialization operation. However, it's crucial to note that once a disk is wiped, the data stored on it will be permanently deleted and cannot be recovered. Therefore, exercise caution when performing this operation!
