- CP>Your friend is correct. Most "wear and tear" on a fixed disk occurs
- CP>during power-up.
-
- Actually, the most frequent cause of disk drive failure I've seen is
- bearing failure, and that's not from turning them on. :-) It was only
- the Seagate 25x and 27xR series that you had to leave on all the time! :-)

- CP>It uses a fair amount. Look up the wattage of your power supply. It will
- CP>probably be around 200 watts (similar to leaving on 2 lamps, but nothing
- CP>like an oven or clothes dryer).
-
- The 200 watts is a maximum power output, that's not what the supply is
- actually drawing, it depends on the system configuration. If you really
- want to know what it's using, you either have to calculate all the loads
- and know the efficiency of the power supply, or do it the easy way and
- just connect a wattmeter to the input. I've done this, and a fully loaded
- 486DX system with two floppies, 850mb hard drive, DAT tape, CD-ROM, and
- 7 of 8 expansion slots used draws just over 100 watts from the power line,
- figuring 80% efficiency of the power supply, it's really only using around
- 80 watts. I'm glad it isn't the power supply rating it uses, because this
- tower has a 375 watt supply!!!
