I am currently repairing my moms computer, the Gateway model (she has to buy these name brand jobs,... always frustrating) in title. Anyhow, after a power outage, her PATA drive MBR got hosed as well as the partition data so I decided that I'd just get her a new drive and work on getting the old one up later. Here's the deal. Her mobo has serial drive connectors on it so I ordered a WD2500KS SATA II drive and it's working and all is fine. Have recovered the other drive too so all of that's good. The problem is that all tools I use to check drive performance show the drive as transferring data no faster than UDMA133, PATA's max speed. This thing should be getting a better transfer speed than that. It has the latest NVIDIA MCP51 Serial ATA Controller drivers installed and the option in Device Manager inside of the controller has it listed as a Generation 2 device capable of 3G/s but the test there says 140 for burst and 65 for sustained. Does this sound right? Also, HD Tune says about 62MB/sec but the Supported and Active connection is listed as UDMA Mode 6 (133 MB/sec) so what gives? Any takers?
