Flash failed when flashing Raw file to usb

I’ve tried several times to flash a raw file 8gb to my usb drive. It will proceed for some time until it pops up saying it ended or dropped out abruptly and that the file may be corrupt, and never completes because of this error. I should point out this is the mac version.

Hi, can you please provide the full diagnostic info? Press Cmd+Shift+I and copy the contents of the console here after you try to flash. This will give us more diagnostic info.
