Using the SCSI Disk Utilities To access the SCSI disk utilities, select the SCSI Disk Utilities option from the menu that appears after starting SCSISelect. Once the option is selected, SCSISelect immediately scans the SCSI bus and displays a list of all SCSI IDs and the devices assigned to each ID. When you select a specific ID and device, a menu appears, displaying the options Format Disk and Verify Disk Media. s Format Disk-This utility allows you to perform a low-level format on a hard disk drive. Most SCSI disk devices are preformatted at the factory and do not need to be formatted again. The Adaptec Format Disk utility is compatible with nearly all of SCSI disk drives. Caution: A low-level format destroys all data on the drive. Be sure to back up your data before performing this operation. You cannot abort a low-level format once it is started. s Verify Disk Media-This utility allows you to scan the media of a hard disk drive for defects. If the utility finds bad blocks on the media, it prompts you to reassign them. If you select Yes, those blocks are no longer used. You can press Esc at any time to abort the utility. Troubleshooting Checklist If you have any problems during the installation, check the following items first: s Have you installed the host adapter into a PCI Rev 2.0 compliant computer? s Are all SCSI devices powered? s Are all SCSI bus cables and power cables properly connected? Is pin 1 oriented correctly? s Does the host adapter and each device on the SCSI bus have a unique SCSI ID? s Did you install your host adapter in a bus master PCI slot? Refer to your computer's documentation for instructions or try another slot. s Are the devices at the extreme ends on the SCSI bus terminated properly? s Does your system CMOS setup require you to enable PCI bus parameters? If so, refer to your computer's documentation for instructions. Check that IRQ channel assignment, board, and BIOS settings have been made. Some configuration options apply to a specific PCI bus slot, so if you change these options be sure you are applying them to the slot in which the host adapter is installed. Check your computer documentation to verify which slot corresponds to which number. - If there is an Interrupt Type or Interrupt Line option in the Setup program, be sure to select Int-A or Interrupt Type = A. Depending on your system design, you may also be required to change a motherboard jumper setting. - If there is a Triggering Interrupt option, be sure to select Level. - If there is an option to enable or disable bus mastering for the PCI slots, be sure to select Enabled. - If there is an option to enable or disable individual PCI slots, be sure the slot in which you install the host adapter is Enabled. - If your computer has a combination of ISA (or EISA) boards and PCI boards, you may need to mark the IRQs used by ISA/EISA boards as Used so the system BIOS will not try to assign these IRQs to other PCI boards. - In some systems the BIOS reserves a set of available IRQs for PCI boards, and you have to assign these IRQs manually. 9
