I have a Toshiba 500 gig drive plugged into a USB port.  ntfs-config shows it as available -- check mark to the left of the drive under Advanced Options.  But when I try to open the drive in file manager or in Deepin Movie (or in vlc, for that matter), I get the following error message:

Error mounting system-managed device /dev/sdb1: Command-line `mount "/media/TOSHIBA_EXT"' exited with non-zero exit status 13: $MFTMirr does not match $MFT (record 0).
Failed to mount '/dev/sdb1': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.


Any wisdom on how to fix this?  Many thanks, as always.
