The same thing happened to my at school on Wednesday and which the same thing happen, I was carrying two. One of them went missing which was the SanDisk Facet Blue 8GB and which it was in my left pocket which I kept my phone, earbuds, and the USB charger. I just discovered it when I got home that day, the other one is a SanDisk Cruzer Green 4GB.
I ordered the same ones from Newegg.com and next time I'll try to keep them in a safe place like inside my wallet and possibly take pictures on my phone to make sure that I can indentify the ones I have? I could also put a password on there too from anyone to access to my data. Will I try to learn from this or will these methods help from?
Just think from a size from a portable external hard drive to a thin size one. Cloud storage is one of the options too but the downside is that you need internet connection to get access to that storage, I like to have a drive better and I can access from anywhere that I don't have to have internet connection.
