Ultra Ata Dock Are There Hard Drive Docks For ATA?

Are there hard drive docks for ATA? - ultra ata dock

I'm not very familiar with the conditions, but this spring I bought my internal hard drive because I need it, take some files, but I heard that they're not compatible. The plugs are different. Spring lasts that I have them. http://www.frys.com/product/5661451?site=sr:SEARCH:MAIN_RSLT_PG

This is a Vantec NexStar Hard Drive Dock Unit

And my internal hard drive, Seagate Barracuda 7200.7 Ultra ATA, if it helps. I'm tryng to find out whether the disk is too old or something. It has many pins? me is IDE?
