560X Enhanced Port Replicator & floppy

["Michael Kutchins" <kutchins@texas.net>]

After working just fine for weeks, the floppy drive on my 560X, while
connected to the enhanced port replicator, suddenly stopped working. 
Connected directly to the TP, outside of the port replicator, it works
perfectly. 

Since I had just upgraded my backup program software (Iomega) I suspected a
conflict. I was really surprised when IBM support said the problem was a
known issue and they'd send out another floppy.  

Has anyone else out there had a similar experience or would care to offer
an explanation as to why it just started?

Thanks,
