[PROBLEM] my external hd will not mount

[Mentalblaze]

Hi.
I have an xbian on a raspberry pi 3 and the axternal HD used to mount but it seema I removed it one too many while running and now it won't show up when I connect it.

The drive is a 2.5 external usb3 hd. and I have a usb with external power on it as well.
The drive works fine in windows (ntfs) but I cant see it in xbian.
I also tried using an usb2 hubb I have without any luck.

I run the xbian from a connected USB stick (sda1) so this should be sdb1, I guess.
Tried "mount" but only the sda1 is shown.

Have there been some remnants left from my pulling the cord that I need to clean up? And if that is the case, how do I do that?
