Common Problems and Solutions s Changed Values Not Loaded-If you changed any values on the host adapter in a Setup program or on a SCSI device, select the Saved option to ensure that the new values are loaded. s Format/Verify Disk Device Utility Startup Fails-If you tried to use the Format/Verify utility on a disk device and got an Unexpected SCSI Command Failure pop-up box with error information, the utility probably encountered a problem with the disk device or the media and therefore cannot run. 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 fixed disk drive, the disk may be physically damaged. Verify and format the media 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. 10
