any requirements for "skipping" header or trailer blocks on "raw" partitions are specific to the PLATFORM and the Oracle version.
for Oracle 8.0.6 on HP-UX 11.0 using "raw" partitions created with the Logical Volume Manager, there is no need to skip any header or trailer blocks with a backup or restore using the dd command.
if your platform does require blocks to be "skipped", account for this both when copying the datafile from a raw partition (backing up) and when copying the datafile to a raw partition (restoring).
