I’ve downloaded the latest dvd of leap 42.1 from the current repo, which is build0114, dated today. The first time was from the metalink and the second time was a direct download. I used dd to make a bootable usb stick and both times the md5sum on the usb didn’t match the iso file. But the md5sum was the same both times on the usb. My machine doesn’t recognize the usb stick as a bootable device. Does that mean that this latest build is defective or could there be something else wrong?

It never does, it is impossible.
You can checksum the iso file and it should match the published hash,
but not the stick.
It can be done if you compare an exact number of bytes. The problem is
that the usb is bigger than the image.

Could be either.
I suppose the target of dd was set to the raw device, not to the
partition or the filesystem :-?

Hi
I would guess it is… 
The official download links to the milestone 1 (build 0017) which I’m currently installing, working fine so far… maybe try that one instead.
From the openSUSE Studio disc image howtos:
- Note: As writing images blockwise is a critical process, please compare the md5sums of the raw image and the newly created device
** md5sum /home/suse/myappliance.raw
md5sum /dev/sdb
**So I was just following these instructions.
Yes.

That’s not likely to work. You are comparing two “files” of different length.
I never check a USB, because undetected write errors are rare. Actually, I use “dd_rescue” to write, which checks as it goes. But it is probably checking the system buffer rather than the final USB.
If you really want to check, perhaps it would work to use:
head -c count /dev/sdb | md5sum
where “count” is the length of the file “/home/suse/myappliance.raw” (as shown by “ls”).
I have not tried the current build. I had no problems installing from milestone1, but that’s an earlier build.

Yes, but it refers to disks. Optical media, like a CD or DVD.
In that media, the apparent “size” of the disk is the same as the image
that was burnt into it. This does not happen on usb sticks or real disks.
