Hi

I have Seagate 1 tb backup drive that worked for about a month. Now my mac does not even know it exists when I plug it in. It does not show up in finder or anywhere. It is lit up so I know it is connected fine. The other day I did get a message that it was damaged and to run the repair in disk utility, which I started to do until it froze and ever since it has not shown up anywhere. I have a question in to Seagate but have yet to get a response. Any ideas?

Thanks.
