Is the error message you're getting in response to the floppy drive or the SSD drive? How did you pull off getting a SSD in there? It sounds to me that that would cause some weird results depending on what kind a adapters/converters you're using.

I'd try a regular SCSI drive with the floppy and see if the error goes away, this way you can see if the error is truly coming from the floppy controller or if it's the SSD that's totally confusing the machine.
