I spent at least 30 mins on the phone with a tech on this same topic.
I got the same e-mail msg as many on here about directories having been exceeded.
The person put me on hold at least three times. My guess was to consult with other members on his team. He said he had never gotten this question before.
Eventually, the tech tried to direct me to a Twonky Server page. But first he kept telling me to put a (.) after http//(name of device).9000. We did this for about three tries, before he told me to replace period with (:) That didn’t work.
Finally, I got to the Twonky Server page by typing in my IP address followed by (:9000). I was then directed to the rescan inteval and instructed to change -1 to 0.
I inquired into what was the purpose of the rescan interval, but the tech could not explain what this function existed for, or how changing it from its current configuration of -1 to 0 could impact the performance of my system.
Last week I purchased a My CloudMirror. By the second day the front LED lights went red, and never changed. I took device back to the store, and got a replacement. I did have to spend some time with tech support for help with the second drive, and the support I got from everyone I spoke with was OUTSTANDING. David at Level 2 was incredible.
I’ve used WD products for many years, and generally have been very pleased with their product and support.
I think my problem is resolved, but I never did get answers to my questions about function of rescan interval, or how many folders can you create if you don’t change the interval. I tried giving an example similar to one below, but the tech couldn’t tell me if this was too many
Share Folder: Pictures
Sub Folders: 200 different ones
Sub Sub Folders 200 different ones in each of the 200 sub folders
Each Sub Sub folders contains anywhere from 200 to 12 thousand pictures
Again, the tech had no knowledge if a scenario like this would generate the directory watch limit e-mail.
If anyone from WD, or fellow posters happens to read this post, I very much would appreciate answers to my questions the WD tech I dealt with could not answer.
