    Seagate Momentus XT SSHD compatible w/ HM55 Express Chipset?

    rclai

      I have an HP DV7 CTO 4000 laptop, here are the details:

      My hard drive is failing (SMART imminent failure) and I was eyeing the Seagate Momentus XT SSHD to replace it, here are the details:

       

      http://www.seagate.com/docs/pdf/datasheet/disc/ds_momentus_xt_retail.pdf

       

      The PDF of my laptop shows a list of HDD configurations and I'm wondering whether I'm limited to those configurations and would have to order a replacement HDD from HP. I also see that the chipset I have is the HM55 Express Chipset and see that it supports SATA 3 GB/s, which is what the Seagate SSHD is able to support (the newer Momentus XT model is 6 GB/s but is backwards compatible to 3 GB/s).

       

      So if anyone can shed light on whether I can replace my HDD with this one please let me know.

       

      Thanks,

      Richard

          Hello,

           

          We do not have a compatibility lists on our I/O controllers and hard drives or SSDs.

           

          The only thing that I see is that using a SATA III hard drive into a SATA II system may not be economically efficient, since anyway it will perform as a regular SATA II device, unless you are planning to change your laptop in the future and keep the driver with you.

           

          Other than this, I consider that this should be fine. Try to chekc with Hewlett Packard* to see if that have heard of any compatibility issues being reported on their systems.

            Okay, that's what I thought.

             

            I was thinking of getting the SATA III one because it has 750 GB of storage. They unfortunately don't have a 750 GB model exclusively just for SATA II, the only SATA II they have is a 500 GB model. But yes, I suppose I could upgrade the motherboard in the future to use its full potential.

             

            I doubt HP will tell me if anyone has had issues with other HDDs not in their list.

              I've only heard of Momentus XT drives having problems with Mac notebooks.

               

              Don't worry about what SATA your drive is and the max the drive supports.  I don't think the Momentus XT 2nd gen can saturate SATA II's 300MB/ps bandwidth.  The drive itself will be faster than the older Momentus XT due to basic mechanical improvements etc. on SATA II, probably even SATA I.

                Just an update that I've installed the hard drive on here and it works like a charm.

                 

                The only weird thing that happened was when I first plugged the hard drive in it didn't work.

                 

                So then I unplugged the SATA cable from the laptop and plugged it back in and plugged back the hard drive back and then it worked.
