Hello, when my friend was formatting my PC two weeks ago, my external hard drive was plugged via e-sata. And due to a accident, the external hard drive's partition was deleted, but it was not reformated and thus I'm hoping there is a way to recover the data. Thanks for reading.

Try Mini-Tool Partion Wizard. It is a free program and it has a feature to restore partitions. This is what i use. Good luck.
