usb fail to be read after an interrupt dd operation












0















Last night, I dd the main mass storage /dev/sda2 to a USB



dd if=/dev/sda2 of=/dev/sdb1


Unfortunately, I plug out the usb before it is finished.



This morning, the usb cannot be read



me@host:~$ sudo mount /dev/sdb1 /media
mount: /media: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error.


How could I solve the problem?
