      Thanks for the reply...

      To be honest, I'm not sure what too familar with /proc/bus/usb/devices, but
      here is the entire listing from my NSLU2:

      (The *only* thing plugged into the NSLU2 is my Ultra ULT31310 USB enclosure,
      which is plugged into Port 2)

      HMm ok. So you have a couple of entries for USB OHCI Root Hub - these are your USB bus entries I think. Your USB enclosure is probably this entry: T: Bus=01

        HMm ok. So you have a couple of entries for USB OHCI Root Hub - these are
        your USB bus entries I think.

        Your USB enclosure is probably this entry:
        T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 2 Spd=480 MxCh= 0
        D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
        P: Vendor=067b ProdID=3507 Rev= 0.01
        S: Manufacturer=Prolific Technology Inc.
        S: Product=ATAPI-6 Bridge Controller

        Prolific are a manufacturer of USB enclosure chipsets. Looks like you've
        got the PL3507, which is pretty common. But according to the above, yours
        (unlike mine!) is being picked up as a USB2.0 device and running at
        480mbit. So I think you're speed problems may lie elsewhere. You might
        want to do some tests copying large files around on your drive to confirm
        whether or not the HD access speeds are the issue?

        Interestingly, my USB enclosure is based on the same chipset as yours, but
        still only runs at 12mbit :(

        T: Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
        D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
        P: Vendor=067b ProdID=3507 Rev= 1.00
        S: Manufacturer=Prolific Technology Inc.
        S: Product=Mass Storage Device

        I'm thinking I'm going to have to buy a new enclosure.

        Cheers,
        Lars

          Thanks for the information!!

          How can I test to make sure the HDD access speed isn't my problem? Do I
          need to copy a file locally and somehow monitor the transfer rate? ...or
          should I download it using FTP on one of my machines connected to my LAN?

          Thanks! Good luck with your enclosure!

            Hi John,

            For access speed, check the "Read and write speeds" from the following page:
            http://www.nslu2-linux.org/wiki/Info/FlashDriveLifespanSurvey


            Hope this helps,

              I basically time how long it takes to copy say a 5MB file (eg: cp my5mbFile
              my5mbFileCopy). On my slug with my enclosure running at 12mbit, this takes
              about 25 seconds (!!!), wheras I think this should take only about 2 seconds
              (or less) at USB2.0 speeds.

              If that's working, you might want to try some similar tests with FTP to and
              from your nslu2 vs between other machines on your LAN to try and narrow down
              where the bottleneck is. Perhaps there are more sophisticated ways to
              profile this, but I'm not aware of them (I'd be interested to hear anyone
              else's suggestions - or any on how I might be able to force my enclosure to
              be used at full speed!)

              Cheers,
              Larz

              Thanks for the replies! According to the FlashDriveLifespanSurvey article, I should execute this command on my NSLU2: $ dd if=/dev/zero of=/file/on/drive

                Thanks for the replies!

                According to the FlashDriveLifespanSurvey article, I should execute this
                command on my NSLU2:

                $ dd if=/dev/zero of=/file/on/drive bs=8192 count=1024 conv=fsync

                However, when I try to do that it says "dd: invalid converion 'fsync'"

                However, here are some other commands I've tried (and their results):


                # hdparm -T /dev/sda1
                /dev/sda1:
                Timing cached reads: 152 MB in 2.02 seconds = 75.25 MB/sec

                # hdparm -t /dev/sda1
                /dev/sda1:
                Timing buffered disk reads: 24 MB in 3.04 seconds = 7.89 MB/sec

                How do those results look? I have no idea what I'm actually looking for...
                (eg. what the numbers should be)
