We can use the data recovery software to try to get the data needed back from the unformatted external hard disk drive. But one thing we should keep in mind is that we should not use the problematic external hard disk drive any more until the data recovery process finished. We will be asked to format the external hard disk drive when we get the information that the external hard drive is in not formatted error. We can format it after all we need have been retrieved.
Other thing we should be careful is that we should plug the unformatted external hard disk drive out of the computer in case of other corruptions before we know how to recover data form it.

Unformatted Memory Card Data Recovery
The unformatted error can also occur on memory card. When you encounter memory card unformatted error, you can use the data recovery software to recover files first of all. And then, you can format the memory card to fix the error. With this software, you can recover photos from SD card, XD card and CF card, etc. If you mistakenly format CF, XD, SD before data recovery, you still have chance to get back lost files as long as you have not written new data to the card.
