Thanks Gert for your thoughts! No, once the drive changed states to 
being read-only, after running my wine apps, the only recourse I have to 
getting it going again is to reboot. I cannot dismount the drive as 
Linux continues to believe some process is using it, even though I have 
killed all the PortableApps processes and stopped the wine server 
itself. It is interesting to note that whenever I get into trouble with 
using the Passport drive,  even the Linux system itself cannot dismount 
the drive during its shutdown process. Which is really surprising since 
dismounting all drives is one of the last things that happens, after all 
other system and user processes have been terminated!
