Thanks!
Well as it turns out, the iPad was maxxed out but not as a result of video/photos. It was an overabundance of apps and music that had tach'd it out.

I was able to see the iPad again (in iTunes) after rebooting my computer and have since deleted apps that I no longer use/need.

Thanks again!

I have this problem too, when I plug in my ipad air to my computer can not connect to iTunes, Was nothing on my iPad.

After endless months of frustration about why my iPad would sometimes sync just fine and other times I'd keep getting the popup message:

iPad could not be synced because it could not be found

While perusing some Apple users' documentation for my old, first generation iPad, I finally found this one sentence buried deep:

iPad must be connected to a power source in order for it to sync.

So, it's not enough for your WiFi to be correctly configured and enabled on both the sending and receiving ends, you must have your device plugged into a power source anyway. Yes, it seems counter-intuitive because we tend to think of WiFi as doing away with the need for wires.
