OK . . . .first things first.
This is not really a HardDrive it is a weak, single disk, portable NAS unit. (network attached storage).
Therefore, things are a bit more “complicated” than for a “just a hard drive”
Your first step is complete. . .you got into the device. I have done it from a cellphone before as well.
Step two: Get it onto your home network. That way, you can access the drive from other computers in the house. If you turn on “Share Content on this network”, you can read files from other computers in your house.
** At home, turn this on.
** At St**Bucks, turn this off (so others can’t access your drive).
When at Starbucks, you will want to log onto the Devices WiFi, so you can see the drive. You will then piggyback through this router, through the St**Bucks wifi to the internet. Getting to the internet through the Drives Wifi is a two-step, therefore a slower than at home. Which is why you don’t do this at home.
Step Three: Remember: this is a “weak” NAS. The tools for accessing this drive from across the internet anywhere on the planet. . .are not there. The WDcloud internet access capability isn’t there. The WD app on your phone should work fine. . . if you are on the same network as the drive. Use the app to play media.
Of course. . .Most NAS boxes don’t have a battery, nor a built in wi-fi router.
The idea behind this drive is not to access files from across the world. . . the idea is to bring it with you. Not quite powerful/flexible enough to have at home as a remote server while you travel. Definitely powerful enough for you to use as a network hub for the family in a hotel room to share files, watch movies etc.
A main use case for this device is to stream to your phone/tablet while in the car. . . . or while on an airplane. You can also use it as a file server in your hotel room when you and two buddies are working on a project in East Timbuktou. The ability to download SD cards without running a computer is also pretty cool (very important in 2015. . but today, I just buy more SD cards)
As a media server, it’s fine. But not really powerful enough to truly run Plex. It runs Twonky fine. Transcoding just won’t work, so video files have to be in the right format for the final user. (transcoding is a no-go for almost all entry level NAS units as well)
The battery and drive is not really an always on-NAS rated 24/7/365 quality. Using it 4 hours a day 3 days a weak is fine.
Look into using Static IP’s for this device on your network. It makes life a bit easier for the inevitable troubleshooting.
