I am connecting two separate external PASSPORT WD Hard Drives to the computer, but it only recognizes one of them. I’ve tried a number of swaps and restarts and reconnections, but it will only recognize one hard drive at a time. If I unplug one, it will recognize the other and so forth. Any Clues?
It’s a Windows problem, signature collision. This post explains what to do http://community.wdc.com/t5/My-Passport-for-PC/Copy-files-from-one-drive-to-another/m-p/277504/highlight/false#M7587
