Hey guys. I know this is an old thread, but I found it while trying to figure out one of my own problems and it seems like it is going to lead me in the right direction.
I allowed one of my friends to use my external drive to copy some stuff I had on there. He has a PC that is apparently infected with a .scr virus.
Obviously the file isn't going to mess up anything on my macbook, but I'm not sure about my Toshiba external hard drive. It has already made a bunch of useless copies of random nonsensical files on my drive and I want to get rid of it before it messes up any of the information I have on there.
I tried sudo rm -r /volumes/volumename/filename and got the password prompt. Then it returned 'override rwxrwxrwx _unknown/_unknown arch,uchg,hidden for /volumes/[volumename]/[filename]?'
Any ideas on how to continue on from here? Or what I may have done wrong?
I appreciate any and all help
EDIT
Also, I responded yes to the override and it returned 'Operation not permitted'
Sorry to leave that part out originally.
