Debian Jessie - System does not switch off after using pendrive with exfat filesystem

["Mr. Goldin R. Bennet" <bennet@nitt.edu>]

Dear Maintainers,

I have a pendrive formatted with exfat file system.  It mounts and  
works well.  When I unmount, the pendrive symbol vanishes from the  
desktop screen.  But stays on in the side bar in the home directory.   
Also, if I try to connect an external disk drive, it does not mount.

Moreover, when I shut down the system after using the exfat pendrive,  
the system does not shut down.  I have to make a hard shut down and  
then restar to make it  work normally again.  That means it has to  
recover the journals.

Please help.

Regards,
