check all the folders including the root. Some people, myself included, create a little text file on the SD card with name and phone number or similar. You may get lucky
Yep, a great idea! I've been doing this with all my USBs for years. Never lost one yet. I work in a school and tell all the students to do this. They seem to lose them all the time.
I also have my phone wallpaper lock screen with my name, email, work phone and ICE details including her mobile for the wife. Means if I put the phone down somewhere all the details needed to return it to me are on the first and only screen folks see without having to unlock the phone.
Great idea with memory cards. Not sure we have this, usually I print a small sticker and wrap it around them. But this works too!
