Lost my pictures on pc because of a corrupt hard

sure put the drive in a external case with a usb conector once the drivers are loaded you shoulld see the drive under my computer.

Data recovery is not a simple task. If the hard drive is not recognized by the pc or as any external mass storage then it is not possible in most cases to recover the lost files.
However, under certain conditions data recovery is possible but still require premium software packages or high professional fees. If your hard drive fulfills the conditions below:

1. Not physically damaged.
2. Can be recognized by the pc and you can open it if you install it as a secondary drive.
3. If you have not already performed any actions to recover the data.
4. And if it has NOT been formatted.

then you can use recovery tools like iolo Search and Recover and the like.
Most of the tools demand a purchase to made before data can be recovered but nearly all can tell in the trial period whether your data can be saved or not.
Search Google for data recovery software for more on them. It is not feasible to give detailed reviews for every software at this place. Please serch the recommendations section of Fixya.
You can also consider professional data recovery service.

Note: The more you tamper with your hard drive, the more it will be difficult to recover its contents.
