Hi jangmi,

Welcome onboard.

Download and install MiniTools Partition Wizard Home Edition 7.6 from Best Free Partition Manager Freeware and free partition magic for Windows 7, Windows 8, Windows Vista and Windows XP 32 bit & 64 bit. MiniTool Free Partition Manager Software Home Edition.

Use the Partition Recovery Wizard in it and try to recover the partition.

( Scroll down to Recovery with Partition Wizard: SanDisk Cruzer Blade 16GB and follow the steps therein.It applies to external Hard disks too though I performed it on a USB flash drive.)

How much data are we talking about here? Can you save the data to dvd and/or thumb drives then format the external drive.
