I recently purchased a 'Western Digital My Book Essential 2TB'(Desktop) external hard drive (with USB 3). I hooked it up, installed the software it was all good. However just now it has conflicted with my other 'Western Digital Elements 750GB'(Portable) external hard drive. I think updating the 'WD SmartWare' had something to do with it. Upon completion of updating that software my 750GB drive would appear as 'Local Disk (I'. Windows would then ask me to format it, I of course said no as I didn't want to cause any damage. I have attached images showing the scenario. My newly purchased drive is the one on bottom left, and the ruined drive is far right. The second image shows that the drive appears to have no data on it, nor have any capability to hold any. Strange how an hour ago I had it filled with about 700GB of files. What should I do? Any recovery software any could recommend? advice? Anything would be much appreciated!
