    More Fake Flash Fun

    Like last time, I’ve come into ownership of a suspicious flash drive that holds a secret: It’s actually a micro SD card and reader… and completely broken 🙂

    Fake Flash Adventures

    I recently purchased a “256 GB” flash drive for $3.  I knew this had to be fake, but I was also curious about how it worked.  It turns out that there was a “256 GB” micro SD card inside of it and I’m pretty sure that’s fake.

    I didn’t get this on Amazon, but here’s a link to basically the same generic thing:

    Here’s a copy of the Amazon item page as of the writing of this post.

    Using the great program H2testw I was able to determine how much actual storage the device had:

    Turns out, it’s a little under 30 gigs.  Well, at least I’ve got a good 30 gigs I can use 🙂

    Of course, I’m not going to trust this for anything important at all, so I’m going to stick it in my Nintendo Switch to use for extra storage.  If it fails, then I’ll just need to re-download any games stored on it.  No biggie.
