090911 -     Ensure your SCSI bus termination is set properly. Only the devices
090912 -     at the end of a cable should have termination enabled. If you have
090913 -     internal and external devices, then the card is NOT to be
090914 -     terminated. Check with your SCSI host adapter manual for more
090915 -     information on termination configuration.

090917 -         [On 011005 reviewed these ideas with Exabyte. ref SDS 38 MV8N
090918 -     ..
090919 -     Make sure your SCSI host adapter is setup properly. This is
090920 -     often easy for PCI/EISA/MCA adapters, but could be a challenge for
090921 -     ISA adapters. Overall, just make sure your SCSI host adapter is
090922 -     not using any IRQs, DMAs, or IO port addresses that any other
090923 -     hardware device is using. If in doubt, consult the manuals or
090924 -     contact the SCSI host adapter manufacturer.
090925 -
090926 -     Use the most current drivers available for your SCSI host adapter.
090927 -     Manufacturers update their device drivers on a regular basis to
090928 -     solve various problems (it always happens). The more current your
090929 -     drivers are, the more likely your system will work smoothly.
090930 -     ..
090931 -     Please check the SCSI ID of the tape drive. The recommended
090932 -     SCSI ID for tape devices is 2, 3, 4, 5, or 6. Using SCSI ID 7 will
090933 -     cause a conflict with the SCSI controller and SCSI IDs 0 and 1 are
090934 -     best reserved for SCSI hard drives. Be sure that no other SCSI
090935 -     device on the SCSI chain is using the same SCSI ID. Multiple
090936 -     devices using the same SCSI ID will cause conflicts on the SCSI
090937 -     controller, not allowing the devices to operate properly.
090938 -
090939 -         [On 011005 SCSI adapter BIOS shows ID is set to 6. ref SDS 38
090940 -         153M
090941 -     ..
090942 -     If configurable, please disable the Synchronous Negotiation
090943 -     option for the entire SCSI host adapter or the particular device.
090944 -     Many modern SCSI host adapters have this configurable through the
090945 -     BIOS or via a jumper/switch setting. Also, if possible, set the
090946 -     bus transfer rate to the smallest allowable, working your way back
090947 -     up until the tape drive functions as expected. Many SCSI host
090948 -     adapters can be set to data transfer rates higher than most drives
090949 -     can accurately handle.

090960 -     Also go into the Device Manager and see who the Provider of the
090961 -     SCSI card driver. If the provider is not Adaptec, you must go to
090962 -     Adaptec's web site and update this driver.
