Why does RAID Utility show a yellow light and report the status “Write cache disabled”?
The write cache is disabled automatically so data cannot be written to RAID volumes when the battery charge is not sufficient to back up cached data for 72 hours. This message is normally encountered when a RAID Card is used for the first time, when the battery enters a conditioning cycle once every three months, or when a computer with a RAID Card installed is shut down for any length of time. If you are using the Early 2009 version of the RAID card you can use RAID Utility to force-enable the write cache while the battery conditions itself. Warning: If you enable the write caches before the battery is fully charged, you might lose some data if the power to your computer is interrupted.
