// ISBN: 1-55558-056-4
// With some hints from http://www.decuslib.com/DECUS/vmslt97b/gnusoftware/gccaxp/7_1/vms/hm2def.h
// Expects the home block to be always in sector #1 (does not check deltas)
// Assumes a sector size of 512 bytes (VMS does on HDDs and optical drives, dunno about M.O.)
// Book only describes ODS-2. Need to test ODS-1 and ODS-5
// There is an ODS with signature "DECFILES11A", yet to be seen
// Time is a 64 bit unsigned integer, tenths of microseconds since 1858/11/17 00:00:00.
