I just installed a new Fujitsu M2652 drive on our server, and I'm having some  
problems with it.  I formatted fine, and the mkfs went ok.  Doing small,  
simple things on the drive is fine, such as creating a single directory, or  
copying a single small file onto the disk.  However, whenever I try to do  
something bigger, such as copying over the entire /usr/local tree, the whole  
machine hangs.  I've tried fiddling aroung with some of the jumpers, but to  
no avail.  Occasionally I've seen errors on the console, but that was when I  
was monkeying with the jumpers.  Has anyone else attached one of these to a  
NeXT, and if so, what jumper settings did you use?

I'm not sure if it's a bad drive, or if I just have something set up wrong.
