Drive Not Recognized Resolutions: Symptoms: n Hard Disk is not recognized or detected by the CMOS/BIOS program, either in the BIOS/CMOS Auto detect feature or in the POST. n Installation errors: (Verify drive is installed properly) — Check Jumpers (master/slave) — Check for Energy Management jumpers — Check power supply cable connections — Check ribbon cable connections — Check for power management software n Compatibility issues: (Drive compatability can prevent proper communication between two drives on the same cable) — Ensure Master/Slave jumpers are correct — Verify that each drive can work alone on the system — Try reversing the master slave roles — Install the second drive on a secondary controller ® ®® ® ® CREATIVE SOLUTIONS FOR INFORMATION STORAGE™ WIN 95 SIG -- Page 18 © Maxtor Corporation 8/97

Not Seeing the Full Capacity Resolutions: Symptoms: n n n General issues affecting drive capacity Data corruption cross linked files Problems loading O. S. system hangs on Boot up ® ®® ® ® n Installation errors: (Verify drive is installed properly) — Check BIOS configuration — some BIOSs do not support larger disk drives. Enable LBA mode in BIOS settings — Install the drive using Max. Blast — Upgrade BIOS or install a BIOS controller card that supports large drives — Install the cylinder limitation jumber if the drive is over 2. 1 gigs and use Max. Blast to install.
