- YDL sees my externalHD, but, can you NOT use just any old external hard drive when trying to back-up blu-rays and ps3 games?
You Can, it just needs to be properly formatted
- If you can, is there anything that needs to be done to the HD before trying to dump files on it?
Just a format (depending on the filesystem)
- Either way, this line:
dd if=/dev/cdrom of=/mnt/sdc/imagename.img
What does this actually mean (i.e. mnt, sdc)? And what would I need to do to get the file to save on my extHD?
dd is a program, the if parameter is where it reads from, of where it writes to, so it reads from /dev/cdrom (the bluray drive), and writes to the device mounted to /mnt/sdc (which could be your external HDD)
To mount, you could pull a 'mount /dev/sdc1 /mnt/sdc' (if the drive is on sdc1)
Not to peddle my own program, but I suggest looking into PS3 SAK, its a bit more user friendly (less stuff to remember!)
