Hello Hubert
[...]
3 first partitions e,f,g and an extended aprtiton which schould be h
But that h partition is not shown in 'parts wd0'
g4u doesn't support extended partitions.
ok, I see, but an extended partition of a msdos-labeled disk is
just a usual primary partition. The maximum of msdos-labeld
partitions are 4 primary partitions or 4 primary and one extended.
Perhaps you would like to have a look at:
http://tjung.lima-city.de/mbr/disklabel/
there are also extracted sectors (binary files, no viruses) of
the uploaded wd0 or wd0d files. If somebody would like to see
these sectors using a hex-viewer, look at that website.
I marked the extended (4th, but must not be the 4th) partition
in the first picture and in this extended, but in fact it is
just a primary partition and all following partitions are inside
this extended (primary) partition (organized like/as a chain)
are usually named _logical_ partition and it seems that g4u (the
tool which save the partition) doesn't have problems to save
these logical partitions and just don't use that letter for
this extended partition.
In the following output of of my parts wd0 you can see that
the letter h is omitted and would probably letter h if the
fourth partition would be used as a usual (single) partition.
btw: the text is seen at that website too, because of the bad
formatting of tb Emails

If your whole machine gets destroyed, I strongly recommend you do not use
uploadpart/restorepart, but uploaddisk/restoredisk, as only that will
restore your MBR=partition table. Without a partition table, your
partition data is useless.
that would be a good feature and as a first workaround the mbr
can be extracted from the whole diskfile uploaddisk, either
wd0 or wd0d by using
dd if=rwd0 of=mbr01.bin bs=512 count=1
of
dd if=rwd0 of=mbr63.bin bs=512 count=63
(for all 63 (hiddden/following) sectors of the mbr)
within the gunziped wd0 or wd0d uploaded disk
btw: I used cygwins dd, which works fine
after a fictive slurpmbr it should be possible to use
slurppart as necessary.
And slurppart could restore any partition as you like,
Especially the logical partitions of an extended partition
and leave the rest of the partitions as they are.
uploadmbr 192.168.2.16 rwd0mbr.gz wd0mbr bs=512 count=63
or something like that?
I agree. It's not there, though. Mea culpa :)
I've been fighting to rebuild g4u recently, with very limited succes :-/
Would like to help you. But not very familiar with netbsd.
But I'm also interested to modify and make the tool more
useful, including more support for foreign keyboards, etc.
Can I send you PM to your email seen at your website?
