Note Wizard - Midi Music Lessons (Strange copy behavior)

Postby crashman » Fri Nov 10, 2017 4:13 pm

Hi,

I bring you today Note Wizard - Midi Music lessons, from MIDImouse Music series.

http://www.mediafire.com/file/4m42dw2kk426q9l/Note_Wizard.zip

Complete as always with manual, scans, etc.
Images of the disk in STX and SCP, both working on Steem and hatari.
But here comes the fun...
When I tried to write it back to floppy, no problem, but then it fails on protection on the ST.
SCP like index, like Splice with 2 revs, 5, revs... None working.
I thought perhaps are those old disks...
try another one. No luck.
Between some tests, I tried the original disk, and... wow! it's not working! fails on the protection too!!!
Then, why is it working on the emulators? because I've tried running from HDD and it fails also if another image is on the disk.
I'm out of ideas...
It's clear that if my original it's not working, none of the copies will be working too, no?
I have to try somethings, but I don't see it clear...
in any case, here you are, a working on emulators release of Note Wizard.

Looking for that soft on A-F, I've found this post:
http://www.atari-forum.com/search.php?st=0&sk=t&sd=d&sr=posts&keywords=note+wizard
When it says it has a "physical marks burned into the disk surface"

Let's see if now arises another cracked copy of this program...

Yo,
Notice it says "LEAVE WRITE TAB CLOSED" on the disk.
If the disk is write-protected, the protection fails (countdown so you can rectify this).
The software writes on track 79 then reads back. If it was written OK like on your normal floppy, the protection fails.
If it returns an error on read like on the original disk, the protection passes.
The trick in emulators is that write isn't emulated for STX or SCP (or IPF/CTR). If you enable 'ghost disks' in the Steem disk manager, the protection will fail because Steem will read back what was written from the STG file.
If you don't, Steem does nothing on write, reads the original disk and the protection passes.

I think I have the tab closed, but I'll verify as soon as I get home.
Thanks.

Interesting, sound as a physically altered disk indeed. That's why the copy doesn't work. Not sure why the original doesn't, unless you write protected it. Writing to the disk is necessary to reliably detect this kind of protection.

Assuming it is a laser burnt hole, it would be great if you could take a picture. But it's not easy. You would need to keep the shutter open and manually rotate the disk until finding the hole. And it might not be easy to spot it.

Absolutely right both of you!
I leaved the tab open...
My original works just fine.
I think I've spotted the mark on track 79.
Tomorrow I'll try to make a photo with a microscope.
Thanks agains Steven and ijor!

Thanks a lot for the pics ...

Seems it isn't a laser burnt hole after all. But a thin, home made, cut in the disk surface instead.
