Iomega power board review

Life is like that.

Can you supply some more details? Is it an external HHD with USB or Firewire or USB 3.0 or eSATA, or what is it?

Did it work before? Is there data on it that you need? And what do you mean by "stopped working?" Does it show up empty, or not show up at all? Can you see it in Disk Manager, in Device Manager, or in the BIOS?

More information will let us make better guesses.

If I had to make a guess at this point I would suggest a recovery utility, but that would be pointless if the drive doesn't show up in BIOS, so a guess at this point is pretty useless.
