"No Writable WD SmartWare Partition Found"

WD External Drives WD Portable Drives
7

I was having this exact problem until just now. 

I read the help file which suggested that I reformat the drive. I opened the “computer management” and went to the “disk management” section. 

The drive was there, but had no drive letter and was not “active.” 

So, I assigned a drive letter and made the drive active and everything worked. 

I’m using Windows 7.
