HELP - I have an Acomdata External Hard Drive (I think 160GB). Have used it sucessfully 1x month for all of my kids pictures (about 100GB) for the past year. Just tried to use it with the same power source as usual, but it will now not turn on and keeps flashing red and green. What should I do?

Try a different power supply. Also check cables from the Ext. Hard Drive to the computer. If none of that helps and you know how, open the Ext. Hard Drive case and remove the Hard Drive from the case. Connect the Hard Drive to the appropriate BUS and power source inside the computer. You may have to adjust the jumpers, probably to a slave setting. If it still doesn't work then the Hard Drive may be toast. This is the reason I always back up important files onto two different devices. If one fails the info is still on the other one. That is all I can think of right now. Hope you get your kid's picts back.
