HI skylinestar,
It would help to know more about your system setup. If you run "
inxi -Fxzd" and "
lsusb" from the console terminal prompt, highlight the results, copy and paste them back here, that should provide enough information.
Most drive checking utilities or console terminal commands do require the drive to be checked to be "unmounted" which can be done from your file manager, or from the console terminal prompt as you did, or from the device notifier icon in your system tray
You can also use a Partition Manager editor like "gparted" to mount or unmount a drive's partitions and to check them. You may first need to install "gparted" from the Software Manager or Synaptic Package Manager. You can also burn a CD/DVD disc or USB stick of "gparted live" iso file and boot to that to check drives and their partitions.
I know the "disks" (gnome-disk or gnome-disk-utility) application can also perform the mount and unmount functions and maybe check the drive's partitions as well.
Are you sure the filesystem on that device is correct?
or
FYI: For a more detailed reply from the check command use -v for verbose,
You can get help information by running the command below for various "fsck" options like "vfat", or "man fsck".
Example command I would use for this
Code: Select all
sudo fsck.vfat -a -v -V -t -p /dev/sdb1
