Check the following if your disk activity lights are on:
SCSI bus parity checking/generation -- This must be enabled
or disabled for all devices on the bus. If all of your devices
support SCSI parity, enable this for all devices.
If not all of your devices support SCSI parity, disable it for all devices.
Terminator power -- Make sure the SCSI bus is terminated correctly;
each end of the SCSI chain must contain terminators.
Cabling -- Make sure your cable and connectors
are in good condition and that the spacing between devices is correct.
Bus device order -- Order is important, especially if you are
mixing SCSI 1 and SCSI 2 devices.
