You can probably determine from the Sense Key information (e.g., 06h - Unit Attention) both the cause of the problem and its solution. Listed below are some of the more common Sense Key values and their meanings: 02h - Not ready-The media is not ready to format. Be sure that media is inserted in the drive and that the media is spun up. 03h - Medium error-The disk media may be defective. If it is a removable-media drive, try using a different disk media. If it is a hard disk drive, the disk may be physically damaged. Try verifying and formatting the drive with SCSISelect. 04h - Hardware error-The disk drive may be defective. Consult the hardware documentation and contact the manufacturer. 06h - Unit attention-The removable media may be write-protected. Disable write protection and run the utility again. s BIOS Initialization Fails-If the host adapter BIOS is enabled but fails to initialize, the system may display one of the following error messages followed by a BIOS Installation Failure message. - Device connected, but not ready. The host adapter received no answer when it requested data from an installed SCSI device. Run the SCSISelect utility and enable the Send Start Unit Command for the device. If the message still appears, follow the drive manufacturer's instructions to make sure the drive is set to spin up when the power is switched ON. - Start unit request failed. The BIOS was unable to send a Start Unit Command to the device. Run the SCSISelect utility and disable the Send Start Unit Command for the device. - Time-out failure during... An unexpected time-out occurred. Check the SCSI bus termination. Then disconnect the SCSI peripheral cables from the host adapter and start the computer. If the computer successfully restarts, check the SCSI bus termination and cable connections. One of the devices on the SCSI bus may be defective. Reconnect one device at a time to isolate the problem. 13
