I ran into this exact problem this morning with my 5300cs, swapping out the Apple-branded 500MB drive for a 6GB IBM TravelStar. The Apple Authorised Repair shop didn't notice that the TravelStar had no jumpers on either the slave or the master so nothing he did, made the drive visible. He popped out the drive with me there (now I see how easily I can work on the machine in future), compared it with the original drive and took the jumper from the 500MB and moved it over to the TravelStar. Then, because none of his external CD drives had worked before, we hooked up my Apple 300 that he had asked I bring with me because it had worked with the original drive.
At this point, with a bootable floppy in the drive and the CD drive hooked up with a bootable OS 8, we were able to at least see the new drive long enough to initialise it into 3 equal partitions. But trying to install an OS failed numerous times with the machine locking up or giving bus errors or Sad Macs. Then we terminated the CD drive (which had _not_ needed to be terminated with the original drive) and I loaded the barest (quickest) system on the computer just so I could verify that it will start on its own without anything being connected to the SCSI port or inserted into the floppy drive. Did numerous restarts and everything worked fine. Doing a Shut Down always requires using the reset button *4* times before it will start. The repair guy said that's a sign of the PRAM battery needing to be replaced. (He had the powerbook to take it through the pre-authorised REA but called Apple to cancel when he found a 1996 date stamp inside the battery bay.) So, I would suggest you check the jumper placement on the new drive and that you consider that there might be a difference in how the drive is or is not terminated. Tomorrow I'll spend time with the drive here when my brain isn't so dead and make certain a full system install works. FWIW >We had the same problem last week with an IBM 6.?
