      Hello!
      Okay. Now the more difficult part. Can you present us with the messages seen
      normally on a native Linux system? These are the dmesg output lines that
      explain what happens when the system starts up. You've already shown us how
      the unit sees the drive, now we need to see the output before all of that.
      And there is a chipset by the way it's just inside the drive case. All WD
      did was stuff one of their regular 250GB drives into a no-name drive case
      and name it after what you've described thusly.

      Hello!
      Typically that's the cable connecting the external HD to the NSLU2. There
      are reported cases of damaged cables causing speed issues. Also cases
      concerning different chipsets used inside these cases. So for my benefit
      who's case did you choose?

      As a matter of interest, I tried doing the same with my Debian/NSLU2
      setup, also using Putty via SSH. The drive is a Western Digital
      formatted with ext3.

        Hi Tomas,


        Thank you for contacting Linksys® Technical Support. I do apologize for the late reply.

        It is good to know that the beta firmware resolved the issue with the NSLU2 you have. Since this is still a beta file, we will wait for our Product Engineers to officially release it to the public.

        Thus, I will forward this recommendation of yours so they will have immediate action regarding the early release of this file and be included in our official website.

        Since you do not have technical concerns already, I will close this case then. After this case is closed, a survey will be sent. You can also give out comments and suggestions on the survey to directly let Linksys know about this.

        For more details and assistance on Linksys products, please visit our online technical support center at www.linksys.com/support and click on Ask Linksys.


        Sincerely,

        In which test is it slower?
