I used to do this, because it didn't seem to cause any issues — until it did, and I lost a lot of data.
People who say this I'll tell you what actually happens so you can know. When you tell it to safely eject all the volatile memory saved in RAM it actually writes to the permenant storage memory instead of holding it in volatile storage. Every time you yank you're betting that its not in volatile storage anymore and was written to storage. That's what safely eject does, forces the CPU to write to permenant storage.
Edit: the problem comes from whats doing what at what time and you will see why you can lose everything.
Maybe you know why does my microSD card get corrupted any time its pulled unless "ejected"? I need to either "eject" if its on my computer or completely power down the device to keep it from corrupting. Ive tested in both camera and 3dprinter with same result.
Is it just a crap card (its kingston 32 GB)?
From what I learned check to see if the card is set for better performance it makes it write to a cache as consequence but makes it faster on the other hand. I had this problem and this was my answer but other software might be messing with it as well but I always safely eject for good measure anyways.
Ill have a look if I can find anything like that, thanks
I simply don't put data I care about on USB drives any more. They are all basically boot drives or a way to transfer firmware files.
