Restore the size of USB drive in Linux
Run lsblk command to find outUSB partition. In this case you see the USB flash drive is sdb so you VERY CAREFULLY run: #sudo dd if=/dev/zero of=/dev/sdb count=100 Create a new partition table in the format you like: #dd if=/dev/zero of=/dev/sdb bs=32k count=1 Create mounting point: #sudo mkdir /media/external Mount the Drive: We can now mount the drive. Let’s say the device is /dev/sdb1, the filesystem is FAT16 or FAT32 (like it is for most USB flash drives), and we want to mount it at /media/external (having already created the mount point): #sudo mount -t vfat /dev/sdb /media/external -o uid=1000,gid=1000,utf8,dmask=027,fmask=137 OR If the device is formatted with NTFS , run: #sudo mount -t ntfs-3g /dev/sdb1 /media/external Note: You must have the ntfs-3g driver installed Unmounting the Drive : #sudo umount /dev/sdb ENJOY
