OS X Odyssey 312 - DriveGauge 2.0 Drive Usage Visual Feedback Utility

Friday, April 25, 2003

By Applelinks Contributing Editor Charles W. Moore

DriveGauge is a simple utility designed to give you visual feedback and information on how full your hard drives are directly on the icon. It works for many different types of media including hard drives (both physical and partitions), iPods, and FireWire drives

Once downloaded DriveGauge will automatically copy itself to your Desktop and you can then drag it into any folder on your hard drive(s) that you'd like it to be in. To remove DriveGauge, just throw it in the Trash and you're done (and there are also some preferences stored in your Home > Library > Preferences folder if you'd like to completely remove all traces.)

Launch DriveGauge and it will automatically build a Volume Matrix containing a list of all your currently mounted drives and relevant information about them. Click the Lock button to authorize your usage (menus and buttons will not work until you do), and then select which volumes you'd like to have gauges on. Simply click the "Apply" button and DG will then draw the appropriate gauge over each selected drive's icon. (changes take effect once the Finder restarts, logout is recommended for functionality to appear in some dialogs and the Dock.) I found that just relaunching the Finder did the trick on my machine.

Note: to restart the Finder, you can choose Force Quit from the Apple Menu, select Finder, and click the Restart button.

DriveGauge fully supports custom icons and you can easily restore these when the "Restore" button is clicked for each selected drive.

The information is available system-wide: in the Dock, save/open sheets, browser views, and of course the Finder. It's even present in the Installer when you choose your destination volume.

DriveGauge is built as a visual interpretation of the UNIX df command (for the curious just open a Terminal window and type df and hit Return) The original inspiration came from an article at Liquid.org (an HCI site that unfortunately is no longer up)

Known Issues
1) Some compositing errors might creep up (jagged edges, black spots)
2) When checking for updates, DG does not currently detect if there's a connection so please make sure you are connected to the Internet before using this feature (this app will lock up if the Internet isn't accessible)
3) The default icon when a custom icon is not present is currently limited to a hard drive icon, so FW/iPod/USB devices without a custom icon will receive a gauged HD as that drive's icon (DG 2.1 will correct this)
4) The Volume Matrix is only created once when first ran; the reload functionality currently refreshes the information, but does not run the df command again.
5) There is a slight delay in relaunching the Finder as it executes it's AppleScripts (this is a limitation of scripting the relaunch via AS)
6) DriveGauge does not automatically update gauges on an icon once applied. You must manually update your drives whenever you feel appropriate. (DG 3.0 will correct this)

Will I continue to use DriveGuage? Probably not. It's a cool little add-on, but a constant graphical monitor of how full one's drives are is not functionally crucial, and I try to keep unnecessary system overhead minimized as much as possible. However, DriveGuage works as advertised, and if it appeals, why not?

New in this version:
• New interface
- Volume Matrix (selectable apply)
- Live preview (before applying)
- In-view statistics (current icon, name, location, percent used) - Dock menu reconfigured for volume matrix interface
• Selectable application of gauges (per volume) • Speed increase
• Reconfigured Internet updating
• New icon
• Distributed as an 'internet-enabled' disk image  
System requirements:
• Mac OS X 10.2 or higher

DriveGauge is freeware

10.2.5 Kernel Panic Breaks 23" Monitor

From Frank Jaeger

Hi there

I run a G4 1Ghz, with a self-powerd ADAPTEC 4+ USB Hub. On this hub I have: Harman Kardon Soundsticks, Epson Printer, Logitech Wireless Trackman On my G4 I have Cinema HD 23 inch (1 months old) On the Cinema I have Apple Keyboard and Wacom Write pad (tablet)

I updated from 10.2.4 to 10.2.5

Five minutes later, I got the same Kernel Panic with the same message as you.

With help from Apple service I could fix the G4 (I am not a computer geek). However:

IT DESTROYED MY HD 23 APPLE CINEMA SCREEN. It has now something like a pixel out (screen is powered on but stays black. Applications etc open on that screen but it stays black). Apple service tried by phone some repair but the 23 inch screen stays black. Apple service recommends to give the screen to repair. To do so I have to leave China and go to Hong Kong because China don’t want repair it (they never did have a 23 inch in repair and there is as of now no 23 inch available for selling in China). So, because of availability, I had to buy it in Hong Kong and with that, my official warranty is only in Hong Kong.

Any idea for a last try to do something via software??

Thanks in advance
Frank Jaeger

PS I tried the screen also on a G4 Power Mac and same result.....

Hi Frank;

Ouch! That's a nasty problem. I don't have any idea what you could try beyond what Apple has already suggested to you.

If any of our readers can think of something that might be worth trying, please let us know.

In the meantime, I hope you have some sort of alternate monitor to use.

OS X and memory

From Bob Booten

There is a thread about OS X and memory over at MacNN forums you might find interesting.

MacNN Forums >Software - Troubleshooting and Discussion >Mac OS X > Memory Usage in OS X

"It seems like people are still wanting to have free memory. It is pointless to have free memory. get a monitor or something that will watch page-outs. If you start paging out like crazy, then you'll know you have some memory problems somewhere. If you aren't getting that, don't even worry about how much memory is being used at a given time. OSX loves memory, as people say, but its also fairly skilled at managing its memory."

Re :Quartz Extreme

From Antonio Strijdom

Or more specifically Warcraft 3 performance.

I've played it a few times with friends using my (now ancient) Pismo PowerBook 400 and I'd say performance wasn't all that bad, considering the Pismo is now the ripe old age of 3. Granted I was playing at 640x480 (the lowest resolution) and only using 16-bit colour, but it was under Jaguar and I didn't notice the cursor jerking around or units appearing out of nowhere (although you could tell a few frames of animation were being dropped). Most importantly, performance was good enough for me to win a few rounds, so it couldn't have been that much of a handicap.

Perhaps performance was improved by the fact that my graphics card isn't supported by Quartz Extreme and therefore free to "concentrate" on the game ?
