I bought one of these drive from TigerDirect, the 16MB buffer, and am having problems with it. I installed it to my Sata connection and running it as my secondary 465GB HD through my NF7-S v2 board. I am running Windows XP Pro BTW. When I copy files to it from my main HD, a WSD raptor 76GB, the files come out with CRC and MD5 checksum errors. I think I may have gotten a bad HD, but I think I will be going with WD in the future if/when I get my refund.
