go site In Finder, click on Finder at the top of the screen, then Preferences. Underneath Show these items on the desktop make sure External Disks is checked. Similarly, click on the Sidebar tab, and tick External disks there.
Now close the Preferences window and check your Desktop and Finder sidebar. If you still don't see anything, make sure Finder in selected, then click on Go , then Go to folder. You should now be in a Finder folder called Volumes that contains links to all of your connected drives and mounted disk images. Is your USB drive there?
If not, let's see if it's connected but not mounting.
Click on Spotlight, and type in Disk Utility. It might pop up before you finish typing. When you see it, hit Enter and let it load.
In Disk Utility, you should have a window with a sidebar inside it. In the sidebar, you should see your internal hard drive and any external hard drives you have connected. Can you see your USB drive in there? Adding a folder is straightforward. Simply drag it to the sidebar, placing it where desired.
Placing a file in the sidebar is done a bit differently in Lion and Mountain Lion; you need to hold down the Command key while dragging and placing. The action of adding files and folders to the sidebar actually creates what amounts to an Alias of your item, but the real one remains in its original location. When you drag an item to the sidebar be careful that you don't accidentally drop it into another folder already listed there.
By default on new machines or freshly installed OS X software, there are that the section under "Show these items on the desktop:" lists a number of any additional attached drives, USB flash drives, iPods, optical discs as Placing a file in the sidebar is done a bit differently in Lion and Mountain Lion;. i just updated to mac lion os and after that, everytime i plug in my usb or hard drive, the icon doesnt show up on my dekstop anymore and when.
To remove the folder or file from the sidebar - remember, you are not removing the original - simply drag the item straight out of the sidebar as if moving it to the desktop. As before, if you are using Lion or Mountain Lion, you need to do this while holding down the Command key. When you let go, you should see a confirming "puff of smoke" and hear a satisfying "poof" sound as your folder disappears.
Oh, I almost forgot. You can right-click or Control-click on any sidebar item to view other actions you can take on the item.
For example, this is the only way you can rename your custom items you've placed in the "Favorites" section of the sidebar. In the final illustration below you see what the "Favorites" section of Finder windows sidebar looks like on my machine; how it's configured, which items I enabled, and how I ordered them. Of course, yours many look differently, but you might get some ideas for your own organization.
We have explored how to enable the viewing of attached storage devices on our desktop.
Over the years, I have observed that many Mac users are not aware of Finder Preferences. I'll tell you what I tell them: If you've already been using the flash drive with your Mac, it may already be formatted correctly, but it's still best to erase and format the flash drive to ensure that the OS X Lion installer you copy to the flash drive will boot properly. The OS X Lion installer application that you downloaded from the Mac App Store includes an embedded bootable image that the application uses during the install process.
In order to create our own USB flash-drive-based bootable Lion installer, we simply need to copy this embedded image to the flash drive. Because Disk Utility's cloning process must be able to see the image file, we must first copy the embedded image file to the desktop, where Disk Utility can see it without any issues.

Updated November 14, OS X Lion installer. This is available from the Mac App Store. You can use a larger drive if you wish, but more important than the size of the flash drive is its speed.

The creation time varies by the speed of the USB flash drive, but plan on 30 minutes to over an hour. All data on the USB flash drive will be erased.
In the Disk Utility window, look for the flash drive in the list of attached devices.
