Query: system failure

First time I used it, I was in a rush because I wanted to restore my computer. I saved some important files onto the flash drive and opened it to check that it was actually saved. When I restored my computer and plugged in the flash drive, all the data was corrupted. I checked from other computers as well, devastated at having lost everything. Nope. The other flash drive that I saved information onto works perfectly fine, though, so I know it's not the fault of the computer.
