Passport for mac says it is full when it isn't

I have a passport for mac, 1 TB.  I says that it is full and won’t load anymore.  I have removed half of what’s on there, but it still says that it has only around 8 MB of storage left.

Hello,

remove the files from the trash bin as well

after that you will see the available space on the drive

this is the way it works in Mac SO X…

thank you very much for responding… I removed everything and still nothing showed, so I just reformmated it and now it is great!..  I appreciate your response…

for in the future…  i would need to remove stuff from the regular trash bin associated with the computer, or does the passport have its own trash bin?
