I have 2 external drives ones of 250 GB WD passport and one Simpletech 500 GB HDD, both USB, the issue is that my 500 GB is giving me an error of not enough permission to copy, extract or delete data, so I tried to delete all the data and still have the same error, so I try to create a new partition and still gives the same error, I try to click on fix disk permissions, but is grey out, any feedback will be welcome, please let me know if you need additional data. thanks.
