Mac Forum / General / Hardware / May 2006power outages
Our power company has this nasty little habit of momentary power outages, usually in the early morning around 7-8 a.m. As a result, I usually have to re-boot my Mac mini and my external firewire drive. (I boot from the external firewire for my OS to run the system, as it is a faster drive) A couple of questions: 1. Is this potentially damaging to my hard drives? 2. If it is, what type of power backup would you recommend? TIA.  Signature"It is easier to fight for your principles than to live by them." > 1. Is this potentially damaging to my hard drives? I'd think so, yes. And to the rest of your equipment. Generally, when an outage ends, the first thing you get is a massive spike due to everything coming on at the same time, in part. > 2. If it is, what type of power backup would you recommend? I always recommend an on-line UPS, but you might not want to pay for that. Certainly SOME kind of UPS with a very short switching time would be appropriate. It's just that an on-line type has no switching time at all. SignatureLife is toxic. It leads to death and too much of it at once can kill you. >> 1. Is this potentially damaging to my hard drives? Oh yes. I had a office in factory park where they were using large high voltage industrial machines on this area. I had so many damages in this time. Not only harddrives - nearly everything went bad. Screens, mainboards, power-supplies, switches, e.t.c.

Is this potentially damaging to my hard drives? Yes. The hard drive can run out of power before it finishes writing a block of data. Data can get scrambled. When it happens too many times you'll run out of spare blocks and the hard drive will fail. > 2. If it is, what type of power backup would you recommend? > TIA. Get a UPS with built-in surge protection. Set the Mini to sleep when it's not active so the UPS will last much longer unattended. Thanks to everyone for their advice on this. You'd think in these "modern" times we would not have this kind of power interruption but it seems our little part of the world does have it.
