Yikes! that was literally the WORST thing you could have done.
You probably fried the SCSI IC. There is another thread here which is recent that the same thing had been done, and if I recall, the OP couldn't fix it even after changing the IC, and its somewhat possible you fried the SCSI controller in the hard drive itself as well. Its on the same bus! if the HDD doesnt work in any other machine now, toss it. And if your current machine now doesnt work with any known good drive, well...
With that said, its likely you will need a new board unfortunately. You live and learn
Worst thing I had ever done was try and get ethernet by forcing a nubus card in backwards on the SE PDS. (I didnt know any better back then). I killed both the motherboard and the card! never could get rid of that checkerboard pattern since then
