Common Quantum hard disk failures
Maxtor bought over Quantum in 2000.
Quantum hard disks are prone to problems of different kinds, depending on the series.
The Quantum Fireball 'AS' is prone to electrical damages. Power surge can cause the drive to malfunction. Chips on the controller card are visibly burnt. Since the chip controls the functions of the hard disk, the hard disk can no longer be started.
Some times a knocking or ticking sound can be heard. This signifies mechanical failure related to the internal mechanisms of the drive. This is notoriously difficult to recover as adaptive formatting is used in the preamplifier assembly.
In a good number of cases, some of the Quantum drives may fail by firmware corruption. They could be detected by the PC system BIOS, followed by error message such as "Primary Disk Failure" and no access to the disk there on.
