External Harddrive Permissions Changed / No Access my external harddrive permissions have suddenly changed.  I am getting mount errors in Disk Utility when I try to verify the disk.  When I Get Info for the drive in question, it states that I have "NO ACCESS", along with SYSTEM, ADMIN, and EVERYONE.  There is an EVERYONE at the top that has "custom access."  If I try to edit or add permisions for myself, it won't let me.

I've found a bit of steps that may be helpful in this situation, but I'm hesitant to go screwing around in there without sepcifics to my situation/drive.  I downloaded Batchmod to try to fix it that way, but I can't see the drive in question in the files window and I can't seem to name it correctly to help it find it.  Thanks in advance for the help!  Cheers, L
Please don't use any apps to do this, just open the terminal.

Try taking ownership first:

sudo chown -R LCLindley.admin /Volumes/Little\ Travel\ Buddy

then try fixing permissions so you can actually read and write it:

sudo chmod -R 755 /Volumes/Little\ Travel\ Buddy
