Autorun a program when you connect a hard drive

[Balfron]

I just bought a portable hard drive. I want to automatically back up my My Documents (not including my music, pictures, videos) folder to it every time I plug it in/switch my laptop on.

 

I can already do this by having a program (I use BestSync) run at startup on my laptop, but ideally I would only have the program running when the hard drive is plugged in, and when it is actually syncing. This will save me having a program running when it isn't needed.

 

I think the best way to do this would be to autorun a sync program from the hard drive. How do I do that? What is the best program to use? Will the program shut itself down after it is syncing?

 

I know you guys will come up with an answer to this

Do Briefcases sync to hard drives? I know they sync to other computers but maybe to other hard drives. (I have no idea how breifcases work but I know they sync:D)

Briefcases seem more suited to having a couple of documents on the go, rather than large amounts of files. It is a solution though - thank you!
