Restoring data from USB drives and memory sticks.
To prevent further accidental destruction of data, mobile storage devices should be mounted as read-only whenever possible before you attempt any recovery operations. SD cards typically have a write-protect switch, which makes it easier to protect them before attempting a recovery operation.
Windows does not have a way to manually mount their file systems as read-only. There is a Registry setting that works with Windows XP SP2 and higher; it forces all USB mass-storage devices into read-only mode.
If you're using a program that supports deep scanning at the cost of a slower recovery process, use it. The speed of this type of scan depends on your system's CPU rather than its I/O, as most of the work involves matching file signatures and checking for false positives. If you're in a hurry, run a deep scan using the fastest machine you have access to.

PhotoRec
PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory. PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted.
PhotoRec is free - this open source multi-platform application is distributed under GNU General Public License (GPLV v2+). PhotoRec is a companion program to TestDisk, an application for recovering lost partitions on a wide variety of file systems and making non-bootable disks bootable again. You can download them from this link.
