Hi Davide,
Just to try and clear up some things about QxlwinReader.
This program reads Qubide image files. These are copies of a whole
qubide disk, copied to a simple file. I should indeed have mentioned in
my reply to you that the "dd" program I referred to is a utility that
comes as standard with Linux and allows you to copy all or part of the
content of some device to a simple file on another device. As others
have mentioned, something similar also seems to exist for windows,
though I have never tried that.
QxlwinReader cannot, and will never be able to, read a disk directly. To
do that, I would either have to be able to access a real disk for a raw
read/write which, unless I'm mistaken, java doesn't allow me to do (at
least not in an OS independent way), or write a filesystem driver: one
for Linux, and another for Windows, probably yet another for Mac etc -
you can see why this isn't feasible.
Moreover, please note that QxlwinReader can only handle "LBA" type image
files, i.e. ones where files are written consecutively to the disk (FAT
allowing), without taking into account that they should be split up
between tracks, cylinders and heads. If I had an example of a Qubide
disk image file actually making use of tracks, cylinders and heads I
**might** be able to figure this out, too. I believe that Alain Haoui
has written a driver for these types of disks.
Moreover, for the time being, QxlwinReader only handles the first
partition of a Qubide disk image file. There is no reason why it
shouldn't be able to handle the other partitions, too - except that,
there again, I don't have an example of an image file with several
partitions, and so would be unable to test this. Knowing myself, letting
out untested software would not be doing you a favour...

Of course I misunderstood and I thought Wolfgang was referring to a floppy
disk transfer. Can you please provide the link for the download of this "DD"
utility?
Thanks

Having had to transfer a full QL system based on SGC/Qubide to .win

Why should dd be a nightmare? Are you aware that dd means a utility program,
not floppies?
[...]
I understand the effort to write such sw might not be negligible, but
a utility which could manage to read native Qubide hard disks on a PC
and transfer files to a .win file (and maybe vicecersa) I think would
be very useful.
If you have a PC with IDE port anyway, then where is the problem to use dd
to get the image?
