3. view the partitioned disk sdc1

Fdisk-l

4. format the partitioned Disk

Mkfs-t ext4/dev/sdc1

5. Mount after formatting

Df-hl view the remaining disk space

Df-h: view the partition size of each root path

Du-sh [directory name] returns the directory size

Du-sm [Folder] returns the total number of MB in this folder.

If UUID is used, run the "blkid/dev/sdc1" command to obtain the disk UUID,

/Dev/sdc1: UUID = "185dc58b-3f12-4e90-952e-7acfa3e0b6fb"

Then, in/etc/fstab, add:

UUID = 185dc58b-3f12-4e90-952e-7acfa3e0b6fb/mnt/mydisk ext4 defaults 0 2
