Problem: SanDisk SD card not found by phone or PC
"My SD card was working flawlessly in the past few days. Suddenly, I go into my media on my phone today and it shows nothing. I go into my phone settings and it says there is no memory card detected. I tried SD cards from three other friends and they all registered fine on my phone so that isn't the issue. I then tried my SD in my laptop and the laptop won't even recognize I inserted a memory card. What could I do? This is a pressing matter because I need one of those videos off of my SD card by next week."

- 2. Why cannot I recover 2GB data for free?

- 3. Why cannot the recovered files be opened?
A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.
