the other day I stupidly inserted my bootable usb stick in my laptop alongside my 1.5 TB external drive. My external drive worked excellent before but now I get this: 

Error mounting /dev/sdb1 at /media/soninjr/Black: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sdb1" "/media/soninjr/Black"' exited with non-zero exit status 13: $MFTMirr does not match $MFT (record 0).
Failed to sync device /dev/sdb1: Remote I/O error
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.

needless to say I'm not that far advanced in Linux to know what to do about this. Please help if you can it'd be much appreciated.

It says that $MFT does not match $MFTMirr. MFT (Master File Table) is a part of the NTFS file system your drive is formatted with. It is like an address book for the system to remember where which files are stored. Because this table is so important, there is a mirrored copy of it.

In your case, the original table and its mirror do not contain the same data, so there is anything wrong with the hdd's file system. Try and hope that Windows' chkdsk /f or another NTFS repairing tool can fix this. Greetings and good luck!
