Firewall hard drive maintenance routine
I recently experienced a firewall freeze/crash and from what I read in the forums, the most common cause is some type of hard drive failure/corruption. I suggest the following:
Create a maintenance routine and/or structure that allows the firewall to check its hard drive at regular maintenance intervals for file corruptions, bad sectors, etc. in order to promote a continuously healthy hard drive and firewall!
Perhaps a parallel/mirrored drive system could both facilitate this maintenance routine as well as improve the firmware update process if it is not already existing.
