AFAIK the K class machines use _High_ Voltage Differentail (HVD) Wide
SCSI for the disks. Most likely your new disks are _Low_ Voltage
Differentail (LVD) Wide SCSI. HVD SCSI is not compatible with any other
SCSI signaling. So no surprise that the LVD disks block the HVD bus.
Either get HVD disks or get a HVD to LVD signal converter.

An other option is to connect disks to the 50 pin / 8 bit narrow SCSI
bus. (The bus that the CDROM connects to.) This SCSI bus uses normal
single ended signaling. Maybe you need to disable wide negotiation on
the disks if they are wide and connected to a narrow bus.
