    I have a New XPS 1340. I ran the Dell Support center diagnostic and all test passed other than the SMART part of the HD. I ran the other diagnostic accessed prior to boot up and it reports SMART is good.

    I have an ST950042 0ASG. The Bios reports eSATA-NONE. Device manager reports it as SCSI. Anyone know what is going on. I hate to call Dell at this point for fear they will automatically want to replace the HD or even try to have me send my laptop in. I read somewhere that a 1640 user had a similar scenario going on and that they removed the Nvidia drivers and used the Win7 generic. How do I know what drive I really have. Is this a on going problem. The drive is suppose to be a 500GB 7200rpm SMART drive. Thanks

    It's not SCSI, nothing uses SCSI anymore except for lagacy systems. The newer protocol is called SAS and it's not used on consumer end systems. That is a SATA hard drive.

    What you might be seeing is that the drive is operating in AHCI mode which is required for SATA to operate at it's full speed and full feature set, which uses the same operational model as SCSI and Raid controllers.

    BTW, if you remove the nVidia/Intel AHCI/RAID drivers, you'll be left with legacy IDE mode support only.

    gaah,

    Thanks for the info. I just was digging around decided to run the dell support utility in windows, and it gives me a FAIL on my SMART test. That got me looking at my Device manger and so on. I do know that I can test the SMART function in the pre boot dell utility and it passes. just wondering why Dell set this laptop up like this. Your theory may be the reason. So far I have no issues with my HDD so I think I'll leave it alone, just strange that the SMART test fails when I test it in Windows. Thanks
