Partitioning your drive will erase everything on it, so make sure you've saved important files elsewhere before proceeding. You can find this in the Utilities folder, located in your Applications folder. You'll find this listed in the left frame. This will open a new window. This will enable partitioning on your USB drive. Ensure that "OS X Extended (Journaled)" is selected from the "Format" menu. This will make changing the partition sizes easier, but the drive will only work with Mac computers. The new partition map will be applied, and the "Partition" button at the top of Disk Utility will become active. This will open a new partitioning window. You can add as many partitions as you would like. You can adjust each partition to be as big or small as you would like. neighboring partitions will be resized accordingly. You can give each partition a unique label, which can be useful for telling them apart. The drive will format, which will take a few moments. You'll be able to see and access all of your partitions while your USB drive is plugged in, just as if each one was an individual USB drive. Because the format is "OS X Extended (Journaled)," the drive will only work on OS X computers. Windows doesn't support multiple partitions on USB drives without special tools.

summary: Back up any important data on the USB drive. Open Disk Utility. Select your USB drive. Click the "Erase" button. Select "GUID Partition Map" from the "Scheme" menu. Click "Erase" to format the drive. Click the "Partition" button. Click the "+" button to add additional partitions. Drag the edges of the pie chart to resize your partitions. Select a partition to give it a label. Click "Apply" to set your new partitions. Start using your new partitions.

You can use this same method for either Internet Explorer, Chrome, or Firefox. If you use Microsoft Edge, you'll need to open Internet Explorer to do this, as Edge does not support this feature. The shortcut you create will usually open in the browser you created it from, regardless of your default browser. Open the exact site you want to make a shortcut for. You can make a shortcut for any website, but you may still be prompted to log in if the site normally requires it. You'll need to be able to see your desktop in order for this to work easily. You'll see an outline of the object appear as you drag. A shortcut to the website will appear with the website's title as the name. The shortcut will use the website's icon if it has one. If you used Internet Explorer to create the shortcut, running the shortcut will always open it in Internet Explorer. If you used Firefox, it will open in your default browser.

summary: Open your web browser. Visit the website you want to create a shortcut to. Make sure the browser isn't full screen. Click and drag the site's icon in the address bar. Release the icon on your desktop. Double-click the shortcut.

Summarize the following:
You must use actual paste, not a gel toothpaste. The paste contains abrasive material that scrapes plaque off your teeth. This will sand down the scratched surface as well, hiding the scratch causing the laser to misread. Baking soda toothpaste works well due to the extra grit. If you're lucky, your toothpaste will list an abrasion rating, called RDA. No one's tested how RDA affects disk cleaning, but a higher rating (120+) should work better. A small dab should be enough. As before, use a clean, lint-free cloth such as cotton or microfiber.
summary: Choose the toothpaste. Apply a small amount of toothpaste to the polishing cloth.
