Online backup company Backblaze has produced another report on hard drive reliability, this time looking at specific vendors and models. Overall, drives from Hitachi (now owned by Western Digital) came out on top, with a 96.9 percent survival rate after 36 months. Second was Western Digital, whose drives had a quick initial die-off, but then stabilized with an overall 94.8 percent survival rate. In a distant third place was Seagate with a 73.5 percent survival rate. In spite of that, Backblaze is now buying mostly 4 TB Seagate drives due to their low cost and steady performance; the company also likes the Western Digital 3 TB Red drives. follow link
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
