And if you look at the icons, it's (at least for me)
very easy to mistake one for the other.
I mean, who can remember whether that extra angle for HVD
is within the diamond symbol or outside of it?
Moreover, it doesn't seem mandatory to display these symbols
on the SCSI devices. With the exception of some IBM parts
I have a pile of disks where only googling or guessing
would tell whether they are HVD or LVD/SE.
Even worse, the vendors didn't seem to care to clearly
identify their HVD host adapters.
