ANY *unformatted* primary or logical is seen as that - which is why if 
you access that volume's properties notebook and look under "details" - 
you'll see the same sort of numbers as are on one of the PIX I just 
posted.  Max 64K allocation units {at} 512 bytes apiece only - hence the 
32MB drive capacity shown. The used space/free space numbers are screwed 
up by the 0xF6 values plastered through it at the beginning in the "FAT".

I knew about the long version - didn't realise there was a quick

What size does MINILVM/LVM/LVMGUI show it as?

an image is only an aggregate collection of sectors, to the imaging 
program, it's Operating System and File-system AGNOSTIC!

Hi Franklin,

You're obviously either doing something terribly wrong with 
LVMGUI/MINILVM.EXE or LVM.EXE or you have *some* weird HDD there!

Download the zipfile I just uploaded to this group's files-area, and 
have a good look at what actually happens in the MBR/EPBR areas, and in 
the DBR area of a partition/voume. You will note that LVM again fills 
the relevant bits of an unformatted partition with 0xF6, the old DOS 
unformatted filler, on a 6GB primary partition previously formatted as 
HPFS, but empty, which was DELETED, then recreated, allocated a C: 
volume to it and on which I then deliberately attempted to format as 
FAT16 under eCS [1.x]. Naturally it failed.

Note that EVERY *partition* that is created under LVM [all flavours I 
guess, but usually I use LVM.EXE] until formatted with a filesystem is 
always given a FS-type of 0x06 - even those intended by you for LVM volumes.

Which of the three LVM-utilities did you actually use?
