Smoothape – Mutterings and Oddities

I have an 8GB memory card that I keep on my keyring. If I ever lost it I don’t have to worry, why not?

1. I have the files backed up

2. The files on the memory card are encrypted.

how is this done?

Create a folder on your desktop, add the files you which to store on the USB card. Open ‘Disk Utility’ (Macintosh HD > Applications > Utilities > Disk Utility)

From the Menu, choose: FILE > New > Disk Image from Folder

Navigate to the folder you created earlier, you will notice that .dmg is appended to the filename automatically.

For image format, you can keep the default ‘compressed’

Finally, the password portion. Under Encryption you can choose None, 128 or 256 Bit. Your choice.

Hit SAVE and you will now be prompted to choose a password. Choose combinations of Letters, Numbers, Symbols.

Click OK and wait. The x.dmg file will appear in the same folder as your original file. Copy this to your USB stick and you are totally secure.

When you want to open the file, just double click to open the DMG, you will be prompted for your password (unless you open on the same computer you created the file, in which case the password may have been stored in your Keychain)
