Memory/Battery problems were detected. 
The adapter has recovered, but cached data was lost. Press any key to continue.

The following error is similar:

Cache data was lost, but the controller has recovered. This could be due to the fact
that your controller had protected cache after an unexpected power loss and your 
system was without power longer than the battery backup time.

• The adapter detects data in the controller cache that has not yet been written to the disk subsystem.
• The controller detects an Error-Correcting Code (ECC) error while performing its cache checking routine during initialization.
• The controller discards the cache rather than sending it to the disk subsystem because the data integrity cannot be guaranteed.
• The battery may be undercharged.
