Hack Correlation

I bought one of these cheap 'wireless drives' from Amazon:  https://www.amazon.de/I-ONIK-70752-i-onik-WIFI-Cloud/dp/B00I16C1K2/ Currently (early 2017) selling for 15E, I think I paid 12E including shipping. This post will focus on basic features and some early data. Later posts will go into some reverse-engineering, featuring a great YouTuber, LiveOverFlow . If you like reverse-engineering you will surely enjoy his tutorials. By the time you read this he will have probably published his first video showing you how to get into the device. He also discovered that a very similar device is being sold under the Strontium Mobile Wifi Cloud (Sri-CUBa-3KW) moniker in US and India. However that one is advertised as having a 3000mAh battery while this one only has a 1900mAh one. Edit The excelent video from  LiveOverFlow  is up:  https://www.youtube.com/watch?v=FxE2ITDWsNE

I've been using a 4GB on an rPI "clone" - the Banana PI - and have been happy so far with everything the board has to offer, as a headless server. However, I started getting some errors after ~3 years of usage, with the card and at one point it stopped booting completely. Nice timing as well, it's not fun losing your music streaming server at Christmas time. Long story short, the card has been used at 80-90% most of the time, which left very little space for wear leveling. I hooked it up to HDMI and could see a lot of error messages on the screen about mmc. So the card was dead and I feared the worst. last backup having been made a month prior to this. Never fear, just writing imaging the card (Win32DiskImager) and copying the image to another 16GB card worked fine. So if you run into this it might be worth it to just try and duplicate the card to another one. In my case, no other changes were required.
