I was hoping you can help me recover data that was on my backup external 2 terabyte drive. There is a lot of photos of our kids when they were born. We really need these photos recovered. The drive was plugged in when I went to town, when I got back there was a ticking sound coming from the HDD. When plugged in it doesn't show up, but when I put the power on there comes a message on the HDD must be formatted before it can be used."
