Sorry, I has thought it was not possible to recover data, I've been
trying to remake a hammer FS on the disk with the same name and try to
recover it. Of course, it didn't work, but I had to try. Finally it
was a bad idea...
If you really want a disk image, I could try to reproduce this on a
smaller disk (actually it was a 500 Gb disk).
It'd be great if we could recover a hammer FS which has its volume
