But /sh can deblock and does, and I can step thru an HDBDOS vdisk with /sh, 
256 byte sector by 256 byte sector.  Nothing skipped, or duplicated.  By 
the above, then a 256 vdisk allocation would be 82,575,360 bytes.  That 
doesn't seem to be so on my system.  If I turn off the deblocking bit, the 
stp still works correctly to select the vdisk, but stepping thru it with 
ded only shows me every other sector when deblocking is turned off.  Or am 
I miss-reading what I see?

Explain please if that is the case.

Thanks.
