I installed portable apps but when I put it on my work computer (where I am not registered as an admin user) I was not been able to access my flash drive. Ever since then I have not been able to access my flash drive. My computer recognizes the flash drive but it says that I have 0 free space and 0 space altogther. Has anyone else had this problem? How could I go about clearing and maybe even reformatting my flash? I have tried disk mangement and it does not recognize it. Any help would be great. Thanks.
