Question

Answer 1

Probably not.
THere is a way you can view videos off a USB using the USB part of the camera connection kit. But those files need to follow a very strict naming convention, as well as the fact that I've literally had a 50/50 success rate getting USB drives to work.
THere is zero protocol support for something like 'hooking a USB hard drive up to your iPad and viewing content off it via USB'.
So in theory, it can work. But it takes a lot of time and fiddling.
If it's something you just have to do, there is a way that works a bit better. Use an SD card - which doesn't trigger the 'draws too much power' warning that most USB's do.
Name your video files with exactly 8 characters (DSC_3454 for example)
Put those video files into a folder named DCIM located on the top level of your SD card
Plug it in with the SD part of the camera connection kit. Your photo app should open and then you can see thumbnails of the videos (consult the ipad manual for the file types the iPad will play)
THe trick is that you can't view them off the SD card. You have to import them onto the iPad, try to open them via the photos app which will then open the video app and you can view the file. You then delete it. (So there is also the complication that you must have enough free space on your device to import whatever video file you want to view)
So it does work but not easily and intuitively.
There are some specific drives out there that may work better for you. The seagate goflex which allows you to stream videos from it to the iPad via an app is one. The Kingston WiDrive I believe it's called may also offer some functionality.
However the iPad was designed with the idea that a user would purchase/obtain all files from or through iTunes or the cloud, so there's no file manager to support what you're wanting to do, so all there are are workarounds.
