When I got my IRIS, it was already
clear to me, that the harddisc was broken. Unfortunately the harddiscs
used in many IRISes are not standard SCSI or old MFM/RLL discs
- no, they are ESDI discs. As fas as I remember, ESDI was state
of the art a long time ago andused in servers and workstations.
But after some years SCSI won the market and ESDI died out. So
it is rather difficult to find some ESDI drives nowadays.
Even worse, you cannot use all ESDI disks in the IRIS, you can
only use the following models:

Of course I also can use ESDI drives, although there are some
ST-506 drives listed above. These require a different controller.
