I have a 2 TB WD My Passport external HD connected to my Airport Extreme station to share with my network. Playing media files is generally fine, but I've encountered some problems and I'm not sure if this is because of the Airport Extreme, or 802.11n. This isn't a problem with the WD itself, because I've experienced this with another external connected the same way. I also want to note that when connected directly to my mac, these problems mostly vanish. Basically, when watching a movie, there is lag sometimes when I try to move around to different time stamps. Occasionally, my media player will outright crash (for reference, I'm using MplayerX 1.0.17). This doesn't happen when I play these files on a USB stick, or when I directly connect my drive to my computer. That in itself, while annoying, isn't a big deal, but there are bigger problems that have actually crashed my finder twice and locked up my system entirely. Simply navigating through folders with multiple media files can cause beach balling sometimes, and whenever I try to manipulate multiple media files at once (let's say I want to delete 20 media files simultaneously), it will either beach ball for a long period of time, or lock up my finder indefinitely. I do not experience these problems when I directly connect my drive to my computer. So I ask again, is this a limitation of 802.11n, or the Airport Extreme itself? A somewhat related question, but is there anyway I can turn off "previews" of media files? These show up (depending on container, for example, .mp4) even in list view, and I believe some of this is caused by this nonsense. I also want to note that for some reason, this problem doesn't manifest itself if I were to access this drive through my iPad through server software running on my computer. I find this...bizarre, as I can navigate through my files much easier even with live preview on. If anyone wants more details on that, I can provide them. Thanks for any help in advance. EDIT: There is plenty of space available on the drive, and the drive itself is brand new, so I don't think it's a capacity issue.
