Hi,
An "embedded volume" refers to an HFS+ volume that's tucked away inside an HFS volume (the so-called "wrapper volume"). The usual reason is that older systems may know how to mount HFS disks but not HFS+ disks and the wrapper volume usually just has a note explaining the volume can't be mounted but their files aren't lost.
Systems that DO know how to mount HFS+ volumes also know how to recognize embedded volumes and mount the embedded HFS+ volume instead of the wrapper volume. I believe by default volumes initialized on a Mac in "Mac OS Extended Format" (HFS+) are created as wrapped volumes with an embedded HFS+ volume, although that may have changed in a recent build.
Hope that helps, -Pat Dirks.

Hi, what exactly does the term embedded volume mean? I've noticed that the HFS MDB has some fields related to this but the HFS+ volume header doesn't seem to. I'm not really using these fields but I'd like to know what they're used for in any case. So if anyone could enlighten me I'd appreciate it. Regards, Nandini Hengen
