TestDisk is a free open source software which helps recovering data from a corrupt usb flash drive. Recently my flash drive got corrupted, and was asking to be formatted under windows once plugged in. I tried opening the pen drive under several operating systems including windows xp, vista, windows 7, fedora, ubuntu etc. But in most of them, “Insert a Disk into drive x” and “Drive is not formatted” error was popping up.
As the data in my removable drive was not that critical, I started experimenting with different free data recovery softwares.
