Check your RAM.  It could be a dead SCSI port, but check your RAM first.

I had a similar problem where I had to do that on my 7600 or it 
wouldn't boot. (BTW, you're now running everything off the slower 5 
mb/sec external bus) All sorts of contortions...the system would work 
with a G3 upgrade or the original 120 card, but not my G4 at all, I 
struggled with it for quite a while then gave up.

Until I got a new 128 mb RAM stick.

Plugged it in, most of my memory was unrecognized.

I then tested every ram stick separately, all worked.

It wasn't until I tried some old 16 mb sticks in conjunction with the 
128 I had problems.

I took the old ram out, everything ran. I restored my SCSI to the 
internal port, everything ran (and noticeably faster!)

I tried my G4 card, it worked fine.

Moral of the story: bad RAM can do really, REALLY weird things to you!

Was it close to where the Cuda switch was? You might have just knocked 
it a little loose. I don't know about the 7300, but in the 7600, here 
are no screws holding PCI cards in place, only the friction of the slot.
