EOS Utility tethering capture (to NAS) issue, bug?

<p>So this really drove me crazy. I searched the whole internet but got no answer.</p>

<p>Basically I connect the 1D Mark IV to computer (tried several PCs including Win7, Win8, WinXP) via USB cable, using EOS Utility, to transfer the photo to computer. My plan was to store the photo to NAS (network storage) directly.</p>

<p>The solution works well when using my WD network drive, all the time. Days ago I just bought a new Synology DS112 + 3TB WD HDD. I did the similar setting, and mapped a folder (e.g. 'test') into 'My Computer'. Then the weird thing happened: EOS Utility said something like 'not enough room, can not capture more photo' with red font on the top, and the shuttle can not be released, camera LCD showed 'PC FULL', then EOS Utility said 'Capture failture'.</p>

<p>This is ridiculours, because the NAS is new and there is more than 2T on it!</p>

<p>Firstly I though it is windows access control, but I double checked, everyone has full access to this 'test' folder. Then I made some experiments, the result is even more confusing:</p>

<p>1, In EOS Utility I set the destination folder to local drive, and it works.<br>

2, In EOS Utility I set my WD Live book mapped network drive, and it works again!<br>

3, Then I use another software DSLR Remote Pro, connect to 1D MarkIV with the same setting, set to Synology NAS. And guess what, it works!</p>

<p>Obviously: Synology NAS is fine, the access setting is fine; EOS Utility can work with mapped NAS, the software is fine. So the conclusion is EOS Utility HATEs Synology?</p>

<p>Then I tried more, and felt that this can be a big. Then I notice that only Synology has more than 2T (2.67T to be exact) free space on the mapped drive, WD or local drive can be big, but less than 2T free space.</p>

<p>I could not test now, but I am wondering if the EOS Utility software has a problem to recognize the more than 2TB space? So the program things the space is less than 0 (overflow). Normally the program tells you how many photos you can take given the free space, so perhaps that's the problem? DSLR Remote Pro is better than EOS Utility, and it can use UNC path but EOS Utility can not, which can be a proof.</p>

<p>This is my only conclustion, but can not find any similar cases on the internet. Since 3TB hhd is quite common now, anyone has the similar problem? Any comment is appreciated. Thanks a lot!</p>

 

<p>Well, set up a small test partition on NAS to know for sure whether there is such limit in EOS Utility. <br>

How do you address your NAS? IP, NetBIOS name, network share? Try different approaches and see if that helps. Also, but this is a very outside chance, the LAN authentication built into EOS Utility might not support/properly process NTLMv2 so all log on attempts are rejected with a bogus error message. <br>

As an aside, although very functional, Canon EOS software seems to be rather rustic in terms of software architecture and is burdened with unnecessary arbitrary constraints and suspect design decisions, so I wouldn't be surprised if there indeed was a 2T disk space addressing limit.</p>

<p>FAIW, I suspect DIM (Digital Image Mover), which is a free/donation utility, would do that transfer for you. It's a great little utility. I can't recommend it enough.</p>

<p>I don't do tethered shooting and I don't have a drive with >2 TB of free space to try this on, but I suspect you're right about a 2 TB limit. 2 TB has historically been a limit <a href="http://blogs.technet.com/b/askcore/archive/2010/02/18/understanding-the-2-tb-limit-in-windows-storage.aspx" target=_blank">in a number of ways</a> and it may be that the code in question was written back when it was a current limit that seemed unimaginably huge, and that nobody's gone back since then and updated the code to fix this.</p>

 

<p>If setting up a small test partition, as suggested by the first response, isn't feasible, then just throw a bunch of stuff into the NAS until free space drops below 2 TB. I've seen some programs that refuse to install due to bugs in calculating free disk space, and this usually fixes the problem. If it works, then you can either change how you allocate space on the NAS so your partition is under 2 TB, or just leave the bunch of stuff there as long as necessary to ensure that free space is always under 2 TB.</p>

<p>Is it possible that this is a limitation of older versions of EOS Utility, and that it has been corrected in a newer version? Are you using a fairly recent version of EOS Utility?</p>

<p>I download photos to my local disk, and then run a backup program to copy the files to my network disk. This guarantees that I won't lose the photos when the NAS disk dies.</p>

<p>I would try two things 1. try creating a windows mount point. 2. make sure your share level permissions on NAS folder are also set to allow full control and read write.<br>

Or dumpt the EOS Utility and use Adobe Lightroom tether capture works great on large drives.</p>

<p>Hi guys,</p>

<p>Thank you very much for the great replies. As I said, this may be fixed by another software, but I really want to find out the root cause. Some notes:</p>

 

<ul>

<li>I have installed the latest version of EOS Utility in case a buggy old version.</li>

<li>I have double/triple checked the permission on NAS folder. Since another software can write to this folder, it should be fine right? I use Adobe LR and love it, DSLR Remote Pro works as well.</li>

<li>Yes, I was trying to set up a test partition on the NAS, but I failed to do it... Synology DS112 is a single disl NAS and I could not create a smaller partition...</li>

<li>I used IP address to find the NAS and mount it. It is common enough and works for other software.</li>

</ul>

<p> <br>

Thanks anyway! I think in the future, if the >2TB HDD is populater, Canon may realize this and fix it! As some said, EOS Utility feels a bit funny for the design and functionality... I would be happy to move to other software! Due to the work flow, I prefer to capture photos to NAS directly, and I really wish the network speed and stability will be even better in the future!</p>
