Have you tried sharing the drive with your wife and setting up a separate account for the share. I have 3 or 4 people set up this way and we can all mount and access the drive at the same time.

@mustangame2 - You might want to try contacting support@pogoplug.com because I'm pretty sure that's not the norm. I would imagine that the ability to mount on multiple machines would be a firmware-level issue, not the hardware itself. What firmware version is your Pogoplug running? I have my drives mounted on 2 machines almost all day, every day...sometimes more...and they're all using the same account/email address (using Pogoplug v2 and S4).
