Hey there! Windows refugee here looking for some help.

I was trying to setup Samba and get a directory shared from the external drive I have connected to my Pi. Got frustrated as I couldn't make a connection from my laptop or PC and decided to yank the drive and plug it direct to the PC, but getting this unknown error now mounting the drive anywhere. I was messing around with the samba conf file replacing the number/letter string back to the drive name--i had gotten an error previously, maybe due to the spaces, so used this string instead. I think I had started looking into mounting the drive but can't find any terminal commands I ran in that respect, and I got interrupted so can't remember what I was doing. I tried putting the path back to the string but no luck. Can someone point me in the right direction?
