Can not mount U drive on Pi3(wrong fs type, bad option, bad superblock) #19

Closed markniu closed 3 years ago

One of the problem U drive can not mount 

   pi@octopi:~$ sudo mount /dev/sda /media/usb
   mount: wrong fs type, bad option, bad superblock on /dev/sda,
                missing codepage or helper program, or other error
                In some cases useful info is found in syslog - try
                dmesg | tail or so.

solution:format it with mkfs command mkfs -t ext2 /dev/sda

   pi@octopi:~$ sudo mkfs  -t  ext2  /dev/sda
