I have a Western Digital my book that was attached to the network. The ethernet and usb component of this device has failed. I removed the drive and attached it via a usb adapter and through a USB Fedora key I was able to see and copy the files. The problem I'm having now is when copying the files back to the reformatted WD drive the copy fails stating a file already exist. Duplicating or skipping the file would be fine by me but the copy simply stops. There are too many files to surgically copy. I'd like to force the copy some way with whatever program necessary. I've read some things about 'ditto' command in terminal but don't really understand how to. My Mac OS is 10.7.5 Thanks in advance.
