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 the vast majority 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 s Default Settings-The AHA-2920C has default settings appropriate for most PCI systems (see the table below). Run SCSISelect only to change these settings.

Settings for Host Adapter and All SCSI Devices The following settings are most likely to require modification. s Host Adapter SCSI ID- This option sets the SCSI ID of the host adapter. To give the host adapter the highest priority on the SCSI bus, we recommend that you leave the host adapter at its default setting of SCSI ID 7. s SCSI Parity Checking-This option determines whether the host adapter verifies the accuracy of data transferred on the SCSI bus. The default setting is Enabled. If any SCSI device connected to the host adapter does not support SCSI parity, disable SCSI Parity Checking on the host adapter and all SCSI devices. To determine if a device supports SCSI parity, read the device documentation. s Host Adapter SCSI Termination-This option sets termination on the host adapter. You can set it to Automatic, Enabled, or Disabled. We recommend that you leave this option set to its default setting of Automatic. When set to Automatic, the host adapter does the following: - If the host adapter detects that cables are con- nected to either its internal or external SCSI connector, it enables its terminators (the host adapter is at the end of the SCSI bus). - If the host adapter detects that a cable is connected to both its internal and external SCSI connectors, it disables its terminators (the host adapter lies between the ends of the SCSI bus). 7
