Turning of media streaming in the general and in shares might be a good idea…but I am not sure if that prevents the program wdmc (WD Media Crawler) from running and indexing the stuff. Up until about a month or two ago, I had left my media streaming off but I used to notice that the .wdmc folder would still get created in any folder I had pics and videos…and also I have seen plenty of others complain that it was still running despite having turned it off…I just never bothered checking. Yes, the wdmc of course takes some toll on the CPU but I don’t think there’s any way around it…but if you copy in smaller batches, I think the system just doesn’t get as overwhelmed as if you do a mega dump of say 300-400 gigs or bigger of media files. And yes, that’s a pain to manually copy some folders and then come back after a few hours to check if the last batch got done and if so, then initiate copy of another batch, but in the end I think with a lot of media files it gets done a bit quicker that way. Or you can just copy them in one shot…it’ll just take longer as long as you don’t care…but really, you’ll get best result on file transfer from an USB connected drive if you do it via ssh.
If this helps you, please feel free to give me a kudo.
