How to Recover Corrupted Files Off an SD Card
An SD card is a memory stick created by SanDisk and used for portable devices such as digital still and video cameras. They are extremely small and can hold any where from a few megabytes (MB) of space to several gigabytes (GB). However, just as with other hard drives and memory devices, files can become corrupt, which will not allow the content to be displayed or opened. There are a few ways to fix this issue.
Things You'll Need
- Memory Card Data Recovery software
- Unlocker program

Click "Next" when the installation wizard launches and then follow the remaining prompts to complete the installation.

Click "Unlock All" and then "Quit." The file can now be opened and the content accessed.
Tips & Warnings
- The Memory Card Data Recovery software is a demo, so it will allow only a small number of files to be recovered. If there are only a few files you need to recover, this should be fine. However, if there are many, you may need to purchase the full version. This can be done from the same link in the Resources section. As of July 2009 it costs $69.
