Hi, I've posted before and got some good feedbacks. In short, my laptop's hard drive died so I was looking for a replacement. I was supposed to get one with ata-6. I recently purchased one on ebay but noticed that it says ultra ata/100 and now I'm wondering if I purchased the wrong one. But the same item on newegg, it clearly says ata-6. So my question is if these two terms (ultra ata/100 and ata-6) are used interchangeably and thus the same. Or did I mess up by buying the wrong item? These items have the same model number. This one here on Ebay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=42184&item=6879594771 has ultra ata/100 but this one on newegg http://www.newegg.com/Product/Product.asp?Item=N82E16822148088 says ata 6. Doesn't that mean they are the same thing?
