Copying CF cards to external HDD

The camera connection kit can only be used to import photo/video files form a camera, SD (not a CF) card or USB flash drive. You can't import other types of files. You can't export any type of files using the camera connection kit. Also, you can't use external devices like a mouse, hard drive, etc. There are 3rd party adapters that can import from CF cards.

There are some wireless external hard drives that can be used with the iPad.

The Kingston Wi-Drive, which costs $50 for the 16 Gigabyte, and then $30 more for every 16 gigs more. It works by you turning it on and then accessing the files on it from an app that you download on your iDevice. You can access music, movies, and other stuff. No connections or anything, it works like a WiFi connection, you connect to it from the setting on the iPad under wireless networks.

Then there is the Seagate GoFlex, which some would recommend over the Wi-Drive. But this one costs $199 and had 500 Gigabytes of storage. It works the sameway as the Kingston: no wires, runs over its onw wireless connection. You can actually fit 300 HD movies on it.

Another option:

Expand your iPad's storage capacity with HyperDrive

An alternate would be to get multiple SD cards.
