When it comes to recovering files from a device, any file recovery software would need to be specifically designed for proprietary storage-hardware features. In order to quickly erase everything from the disk, using /dev/zero or simple patterns can provide maximum performance, while adequate randomness may also be advantageous in certain cases that should be covered in #Data remanence.

Every overwritten bit is crucial in providing a level of data erasure that prevents recovery with normal system functions (such as standard ATA/SCSI commands) and hardware interfaces. It's possible that there may still be unencrypted data left on the device, which you want to protect against simple forensic investigation using file recovery software. Such investigations can be easily accomplished with tools like Starus File Recovery 6.8.

One of the most common use cases for completely and irrevocably wiping a device is when it's going to be given away or sold. This ensures that all data left on the device is erased, preventing unauthorized access to sensitive information.
