Display Disk Space and File Info on the Desktop
Jun 1, 2007 - 3 Comments
Here’s one of my favorite Mac OS X tips, allowing you to see some useful information right on your desktop. Here’s how to do it; from the Desktop, navigate to the ‘View’ menu down to ‘Show View Options’ (or just hit Command-J). From here, you’ll want to click the checkbox next to “Show item info”, now your data drives will show total and free space, and images will show dimensions!

Great!! I never knew about this but I like it and used it immediately!
This is a easily overlooked and great feature for sure, you can also enable it in individual folder views which is very useful and shows the number of items in folders
Regarding harddrives…
Check this dude out… A genuine OSX Leopard harddrive
LOL
