About a year ago, I made rips of a bunch of my CD/DVD games and packed the originals away.
The problem is that now I'm trying to use WinXP Pro on VirtualBox on OSX Snow Leopard to play these iso images. I used dd in Terminal to make most or all of these images, but when I try to load them as a virtual cd in VirtualBox, they don't work.
I tried iso files I obtained by other means, and they worked fine, so I tried diskutil to find out more. The error message I get from trying to mount throught that is, "No mountable file systems." The only disk image that works was from a dvd.
I've forgotten the exact paths or options (probably none) I used when I made these images, but I know I used dd.
Reading around, I found the following link:
dd producing corrupt ISO images on Snow Leopard (whether invoked from a script or the shell)
From this, I'm guessing there's a high likelihood that I did the dd wrong (e.g. dd if=/dev/disk1 of=image.iso). If so, is there any way to manually repair these images, or will I have to download or re-dd these?
(Also, for my own learning, is this an OSX-specific dd bug/feature, or linux, too? Was I ignorant in thinking that dd if=/dev/whatever of=whatever.img would give a raw binary dump?)
