Mark,
For instance, I have a HFS+ image, burned on a CD-ROM, which doesn't mount. The Disk Utility says that the node size is incorrect. I would like to check what fsck_hfs says indeed. However, since the unmounted CD-ROM is not listed by rge df command, which symbolic name should I use?

Thanks for the information.
Not much more information, but more precisely, since fsck_hfs displays a line stating which part of the disk it is testing. For some problems occuring in a B-tree, for instance, it is better to know which one.
