BACKGROUNDThe data stored on your hard drive is vulnerable to magnetic fields, power fluctuations, oxidation, solar flares, cosmic rays, static electrical charge on your own body, and probably karma. It is not a matter of
if your drive will become corrupted, but
when and
how often.
Minor problems can become major disasters given enough time - often measured in seconds, but more typically in days. So it is wise to perform regular maintenance on your Macintosh. Fortunately, there are several free tools that can help with this - AppleJack and Mac HelpMate.
MAC HELPMATEMac HelpMate fills the gaps left by AppleJack. In addition to the ability to perform many routine maintenance tasks, it can also be used to allow our consultants to observe and control your computer over the Internet to assist with technical support and training. It can also perform automated hourly diagnostics and notify our office if a potential problem is found. If you are interested in these last two services, please contact our office at 505.453.0479.
