Previously working USB External won't mount.

I have a 400GB SEAGATE - External SATA (eSATA) Hard Drive which has been working for over a year.

It last worked Saturday night, I disconnected it and reused it today, however it won't mount?

Can you see it in Disk Utility? If so, hit Verify Disk and/or Repair Disk. Does that help?

did anything happen like a power outage while it was last mounted?

the usb lead wasn't connected to the drive... i'm officially as intelligent as a door knob.
