Unpartition Hard Drive Debian

只是想知道如何在debian下取消硬盘分区

我最近分区使用

cfdisk /dev/sdb 

并希望恢复我所做的。

谢谢

 cfdisk /dev/sdb 

然后对每个分区使用命令“d”。

  man cfdisk COMMANDS d Delete the current partition. This will convert the current partition into free space and merge it with any free space immediately surrounding the current partition. A partition already marked as free space or marked as unusable cannot be deleted. 
 dd if=/dev/zero of=/dev/sdb bs=512 count=1
