This is an issue that has been confirmed with Quantum. According to Quantum, the write back cache does not always function properly. At shutdown, the drive does not flush its cache and write the data to the hard drive like it is supposed to, thus leading to data corruption. The data corruption that is associated with this problem has appeared on all Fireball series through Q109. Power Computing only ships one drive that exhibits this issue: the Fireball 1080. The "1080" refers to the storage capacity of the hard drive.
Power Computing wrote the Fireball Fix, a temporary workaround to resolve this issue with corruption on Quantum Fireball 1080 drives by disabling the write back cache. The Fireball Fix is no longer available, as the problem was addressed in version 1.7.7 of FWB's HDT Primer PE, and in version 2.0 and later of FWB's Hard Disk Toolkit. Releases of the PowerCD earlier than 2.2 do not have version 1.7.7 of HDT Primer. If a PowerComputing customer has an older version of FWB Software and would like to purchase an upgrade they can contact Ph# 510-252-2090. The upgrade prices range from $29.00 - $49.00. Version 1.7.7 of HDT Primer PE is also on the Universal 7.5.5 CD (Part Number 6010-1029-00).
