It's always embarassing for me to have to ask Amiga questions
here, but here goes...
I'd like to make archival copies of the hard disk partitions
in an A2000 and an A4000. I've got network cards and NFS running,
so I want to find a tool for the Amiga that will convert a hard
disk partition to an .HDF file that will mount under WinUAE.
For example, I'd mount my NT machine's P: drive as NTp: on
the Amiga, and the utility would write directly to "NTp:foo.hdf".
I tried this once before with 'packdev' and no compression,
but the results apparently weren't .HDF files and crashed
the WinUAE emulator.
Am I missing something obvious, like that the ADF-based tools
will work with hard disks, too?

I did archival copies today, but they're on a DDS tape. =)

Haven't they once changed the format too, or was that just the addition of the
.HDF extension?

I recall reading a document about how someone transferred his HD to a HDF
file, and I actually believe that he used Transdisk. OTOH you could try
connecting the drives directly to the PC and do a "dd" or similar.
Well, at least it's doable.
Another idea would be to start UAE, install AmiTCP, or at least amiganetfs,
and transfer the disk contents that way.

According to the HDF file format docs, an HDF differs from an
ADF (floppy) file in that it has "a bootblock, a rootblock, a
[block] bitmap and perhaps dircache blocks."
OTOH you could try
connecting the drives directly to the PC and do a "dd" or similar.
I saw a tool to do that, but it warned that sometimes the
drive becomes unreadable. It doesn't sound like a read-only
tool. I don't understand why they'd write to the disk if I didn't
ask it to.

I think I'd lose information. I don't trust the mapping of filename
characters, for example. I doubt Amiga file comments would be
preserved via NFS, too.
As I said, I've already got an NFS link to my PC. I can easily
"copy dh10:#? NTp: all" and send the files as files to my PC, but
I don't want to spend hours figuring out which files were lost.
Having an HDF file on my PC would be delightful. I installed
a Windows program called ADF View. It's a Windows Explorer extension
for ADF and HDF files, meaning now those two file extensions have
their own icon linked to this program, and when you click on
an HDF file, it opens a new Explorer window and lets you
browse the HDF file as if it were part of the Windows file system.
Very handy!

Well, all right, but then wouldn't a grab of the HD result in those attributes
being saved, or do UAE hardfiles lack a real rigid disk block?

Probably the programmer doesn't either, but wants to be on the safe side. =)

I'm not recommending that you use NFS, or that you save the files into a
Windows folder, but that you set up a hardfile in UAE tpo copy the contents
into.
Since you then would have a hardfile with a real Amiga filesystem (well, as
real as a hardfile might be), and would be using amiganetfs (which is not the
same as NFS), a filesystem which works on a very low level, the copy would be
just the same as if you had done the copy between two drives on the same bus.
I've done backups between Amigas using amiganetfs, and all attributes are
saved. I just did an ls of the backup, and it contained file comments and all
that.
As I said, I've already got an NFS link to my PC.
I can easily
"copy dh10:#? NTp: all" and send the files as files to my PC, but
I don't want to spend hours figuring out which files were lost.
That's why you should do the copy straight between the Amiga and the emulated
environment, without passing through any alien file systems or network
protocols.
Having an HDF file on my PC would be delightful. I
installed
a Windows program called ADF View. It's a Windows Explorer extension
for ADF and HDF files, meaning now those two file extensions have
their own icon linked to this program, and when you click on
an HDF file, it opens a new Explorer window and lets you
browse the HDF file as if it were part of the Windows file system.
Very handy!
About as handy as you get with an emulator...

I'm not sure about writing directly to a hardfile. I find it more useful to
copy the hard disk to a Windows directory and have the emulator use this as
a virtual hard disk. It is easier to manipulate file formats using the two
operating systems.

It looks like the Amiga Forever (commercial $30) package includes
a tool called "Amiga Explorer" to mount an Amiga's drive over the
network to the emulator, which would allow you to copy the
remote hard drive partition to a new emulated hardfile, because
it's a file system.
Amiga Explorer is a Windows namespace extension, placing your
networked Amiga on the same level of as "My Computer", which
would allow you to copy to a hardfile while using the emulator:
http://www.softhut.com/cloanto/aexplorer_screen1.html
I would guess that what I created with 'packdev' is an
exact copy of the partition's blocks, but minus the other
partition info that's no doubt included in the hardfile.
I'd feel like I'd truly archived my Amiga if I had a
hardfile, written from the Amiga and stored as a single
file across the network.
I don't like the feel of these networked filesystems, mapping
between Windows and Amiga. I know deep in my heart some bits
will be lost, be they file comments, improperly mapped and
remapped characters, file attribute bits, etc.
