Once every few days my PS3 can no longer see the pogoplug.  When I go into my.pogoplug.com I find that the drive's Media settings are reset to disabled.  I turn it back to enabled, and save settings, and the drive immediately appears on the PS3 again.  What is causing it to lose the settings?  I haven't had power outages (that I'm aware of). 

If connection to a drive is interrupted for some reason, do these settings revert to defaults?  I was hoping they'd be more persistent.
