External Time Machine HDD not being recognized anymore

[holden57]

Hey everyone. So I'm currently running Mac OS 10.6.1 on my MacBook, however my External HDD which was originally working with Snow Leopard is no longer working. It is not recognized by the computer as even being there. I have never dropped it or anything, and I don't know why this is happening. Any advice or suggestions would be very helpful, since having a back up is important to me.

What External HD do you have? (Make & Model)

I have, I believe, the Iomega Professional Desktop eSATa/USB 2.0 1TB
