Open Files with Finder's App Switcher

Say you're in the Finder looking at a file and you want to open it with an application that's already running but which doesn't own that particular document. How? Switch to that app and choose File > Open? Too many steps. Choose Open With from the file's contextual menu? Takes too long, and the app might not be listed. Drag the file to the Dock and drop it onto the app's icon? The icon might be hard to find; worse, you might miss.

In Leopard there's a new solution: use the Command-Tab switcher. Yes, the Command-Tab switcher accepts drag-and-drop! The gesture required is a bit tricky. Start dragging the file in the Finder: move the file, but don't let up on the mouse button. With your other hand, press Command-Tab to summon the switcher, and don't let up on the Command key. Drag the file onto the application's icon in the switcher and let go of the mouse. (Now you can let go of the Command key too.) Extra tip: If you switch to the app beforehand, its icon in the Command-Tab switcher will be easy to find; it will be first (or second).

No Correlation Between Heat and Hard Drive Failure

Send Article to a Friend

The folks at online backup service Backblaze have once again taken a statistical look at their hard drives to find out if they’re affected by temperature.

The results seem to counter our general recommendation to give hard drives plenty of ventilation room in “The Care and Feeding of External Hard Drives” (28 April 2014). Overall, Backblaze found no correlation between heat and failure rates, with one exception: the Seagate Barracuda 1.5 TB drives, which failed slightly more often when run at higher operating temperatures. But the Hitachi drives surveyed actually failed a bit more frequently at cooler temperatures. It’s worth noting that the drives experienced average temperatures between 22° and 30° Celsius, well below the 55° to 60° maximum operating temperature recommended by drive manufacturers.

In any case, it’s still important to run drives within their specified operating temperatures, which means giving them sufficient ventilation. As long as you don’t block cooling vents or put them in insanely hot environments, they should not be adversely affected.

Comments about No Correlation Between Heat and Hard Drive Failure

Where are they measuring temperature? These don't appear to be SMART sensor numbers as they are much too low.

For example, my Hitachi SMART reading is 38C inside an xServe with avg inlet temps of 22 and an internal ambient of 30. (Inside a server room at 21.)

The article graphs the Hitachi from 21 to 31 which suggests they are using internal ambient or something else external to the drive.

I realize SMART stats have their drawbacks but I would think that the temp would be more useful if trying to find direct correlations regarding temp.

Anyone?

They seem to be measuring ambient air temperature in their drive pods, which would likely be lower than the SMART-reported temperature within the drive itself.
