Führt Windows 8 eine Mid-Level Formatierung durch?

Changes to Commands in Windows 8

Several popular Command Prompt commands received some tweaks from Windows 7 to Windows 8:

Format

The format command has had a /p option since Windows Vista which acts as a basic data sanitization tool, performing a write zero on each sector of the drive as often as you specify (e.g. format /p:8 for eight full write-zero passes). In fact, the /p option is assumed unless you perform a "quick format" using the /q option.

In Windows 8, however, the functionality of the /p switch has changed in an important way. In Windows 8, any number specified is in addition to a given single write zero pass. Furthermore, each additional pass overwrites with a random number. So while format /p:2 in Windows 7 would overwrite the entire drive with zeroes twice, the same command executed in Windows 8 will overwrite the entire drive with zeroes once, then again with a random number, then again with a different random number, for a total of three passes.

No doubt this change in function is designed to provide a bit more security when using the format command to sanitize a drive. See How To Wipe a Hard Drive, Free Data Destruction Software, and Free File Shredder Software for more discussion on this topic.
