I've done quite a bit of hacking with ods2, at least enough to get it to do what I want. What do you want it do to? Disk geometry isn't needed to read files on an ODS-2 volume IFF the first home block is intact. Indeed, if the first home block is damaged and you need to find another, you need to initialize a disk, you want to read an ODS-5 volume, or some other operations, you may need the geometry. If the home block is good, it points to everything else needed to read a non-corrupted image. If you can get that far, the SCB in the BITMAP.SYS file does contain the geometry (at least the parameters VMS initialized the volume with).
