External USB HDD and Poser Libraries



  • This is great information. Thank you for sharing it. Others using Poser with external runtimes may also find it valuable for reference.

    @ibr_remote Sadly, it is far from solved... I have now determined it is not a network issue, but something in this one computer's installation of Windows 7 premium interfering with the Library manager (got tired of the library timing out, so I copied the offending runtimes first to a 5tb USB drive... same problem persisted and thought it might be related to what you have so I copied the runtimes to the internal HD on the computer and still the problem is persisting... none of my networked Win XP machines have this issue).

    @shvrdavid yes, this is on my home render network. The network only interconnects the machines for the purpose of sharing content via Queue manager (or for lightwave Screamernet) and sharing runtimes between my old fileserver and my newer 64 bit machine. The only machine giving me trouble is the newer 64 bit machine running Windows 7 Premium. Sadly it is even giving me trouble with the library with the runtimes on a local drive, which is problematic as I intended this machine to be my new workstation.

    I am taking a short break today because I am fed up with looking at registry screens, Group Policies, and firewall rules (and yes, I have told it to turn the firewall off, but somehow things still get blocked on my local network... hate Windows 7)

    What operating system is on the system, that the files are on?
    And did you turn off auto disconnect on that machine? (net config server /autodisconnect:-1)

    @shvrdavid Initially the machine they were on was Windows XP Pro 32 bit (my older workstation trying to turn into fileserver due to massive HD capacity). These were being shared over local network with multiple computers (two Win XP Pro 64 bit machines, and 4 Win XP Pro 32 bit machines... the 4 32 bit machines were Dell's I salvaged and rebuilt back in the day). I have since moved the runtimes several times - all on to the Windows 7 Premium 64 bit machine that I am trying to make my new workstation (first to external, self powered 5tb USB drive, then to one of the internal HD partitions).

    Autodisconnect is off. I also have the power config setup so that no drives are spun down or idled while the machines are on.

    Since the issue does not happen on any of the Windows XP networked systems when I open Poser and load the library, I am fairly convinced it is something in Windows 7 causing the issue. I have tried going through the various Firewall, Group Policies, and even certain known registry keys to fix possible causes (and am finding Wind 7 does a lot I do not like...like ignoring whether the firewall is on or off, still need rules to allow certain programs). I am admittedly not as familiar with 7 as XP though.

    This behavior with the library for me is happening across Poser 8/2010, Poser 9/2012, Poser 10/2014/GD, and Poser 11 Pro. I had already had a fairly lengthy tech support ticket, tried the Internet Explorer 11 fixes, tried a number of Flash and Air fixes, and at one point it almost seemed fixed (until this past week when I am on a deadline for a number of very high resolution renders that my 32 bit system just can not do or even compose all of the elements into Poser for).

    On the upside, I am keeping notes of some of the possible fixes as I go to include in the troubleshooting guide I am always expanding. It needs it's version 2 finished up though and published.

    By chance does the computer that drops the shares have a Broadcom or Intel NIC?
    Some of those ignore auto disconnect settings in Windows.

    You can find alternate drivers for some of them that enforce the Windows setting.


  • Poser Ambassadors

    @shvrdavid I will have to check that when I go home. I was not aware of that, but it's good to know. Though the NIC shouldn't still be causing the problem with the runtimes locally.


  • Poser Ambassadors

    The Workstation with the issues has a Broadcom NetXtreme Gigabit card for networking.

    Check these two registry keys.

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters\size
    Your choices for this registry key are 1,2 and 3. Should be set to 3 for file sharing
    1 = Minimize Memory Used
    2 = Balance
    3 = Maximize Throughput for File Sharing and Maximize Throughput for Network Applications

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

    Your choices for this registry key are 0 and 1. Should be set to 1 for file sharing
    1 = Maximize Throughput for File Sharing
    0 = Maximize Throughput for Network Applications
    Some programs, such as SQL and Exchange, set this value during an installation. For these programs, the optimal setting is 0.
    0 = Indicates that the computer does not go outside its cache pool and use program memory to perform I/O functions.

    1 = Indicates that the computer looks outside of of the allocated cache pool and uses program memory to perform I/O functions. This occurs if the cache is full.

    You may very well be running out of NIC cache space and Windows is not setup to deal with a NIC driver that does. Manually increasing the cards memory allocation may help as well.

    Are you using the Windows drivers for the network card, or the Broadcom ones? (I believe there is nothing written to the bios on that series chip, and the bios is written in during bootup) Might be worth a shot to use the try the other driver from what you are using.

    Looking thru some stuff, go to that machine, go to the device manger and turn off the following in the advanced tab of the NIC.

    • Interrupt Moderation - clumps packets together and sends them as a batch - the main offender
    • Flow Control - sounds counterintuitive to disable it, but it messes with existing flow control in Windows networking stack
    • Receive Side Scaling - also messes with Windows networking stack
    • [anything goes here] Checksum Offload - supposed to speed up performance by offloading TCP/UDP checksumming to hardware; in reality does nothing for an average desktop PC except interfere with Windows networking stack
    • Green Ethernet - performance-eating eco garbage

    Curious to know if this is the root issue causing your problem.

    Here is the long version of it from Microsoft, this applies to any file server, no matter what op system version from NT 4 up.
    Your basically just changing the way it talks to the router/switch/nic to eliminate the chance of errors.
    Any other NIC talking to it is forced to do communications in an error correcting way only.
    You probably will notice a speed difference as well, it will increase.

    Haven't had a chance to try any of this yet - will let you know after I do.
