Hey Nik,

Did you unmount the disk first?

Hi,
I'm using "BetterAuthorizationSample" from apple, which installs a privileged helper tool for performing privileged operations.
While using this I can obtain a valid file descriptor for reading any disk, I can not get a valid file descriptor for writing to disk (/dev/rdisk1, which is a pen drive).
I'm using:
fileDesc = open(path, O_RDWR);
in the privileged part (helper tool) of my code.

Any help would be greatly appreciated.

Wishes,
Nick
