I'm trying to mount an external Toshiba USB drive in Ubuntu 19.04. No entry appears in the file manager gui when the drive is plugged in. fdisk shows...
ewan@tiny:~$ sudo fdisk -l ... Disk /dev/sdb: 698.7 GiB, 750156374016 bytes, 1465149168 sectors Disk model: External USB 3.0 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX [redacted]
I used gdisk to partition the drive, and listing partitions shows:
Command (? for help): p Disk /dev/sdb: 1465149168 sectors, 698.6 GiB Model: External USB 3.0 Sector size (logical/physical): 512/512 bytes Disk identifier (GUID): XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX Partition table holds up to 128 entries Main partition table begins at sector 2 and ends at sector 33 First usable sector is 34, last usable sector is 1465149134 Partitions will be aligned on 2048-sector boundaries Total free space is 2014 sectors (1007.0 KiB) Number Start (sector) End (sector) Size Code Name 1 2048 1465149134 698.6 GiB 8300 Linux filesystem
The partition changes were saved with the gdisk 'w' command.
Using lsblk shows (drive info redacted):
ewan@tiny:~$ lsblk -fa ... loop22 squashfs 0 100% /snap/gnome-system-m loop23 squashfs 0 100% /snap/gnome-characte sda ├─sda1 vfat XXXXXXXXX 503.4M 1% /boot/efi ├─sda2 ext4 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 412.8M 34% /boot └─sda3 crypto_L XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX └─sda3_crypt LVM2_mem XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX ├─ubuntu--vg-root │ ext4 XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX 110.5G 47% / └─ubuntu--vg-swap_1 swap XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX [SWAP] sdb └─sdb1
When I try to mount:
ewan@tiny:~$ sudo mount /dev/sdb /media/usb/ NTFS signature is missing. Failed to mount '/dev/sdb': Invalid argument The device '/dev/sdb' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
Any suggestions please?
