'NoneType' object has no attribute 'decode_raw'

[Bzzz]

Hi,

new greaseweazle v4 user here - I've read a couple of 5.25" HD disks without problems (amazing!) and still have a couple of lower density ones left. Those will read fine as well, but there's no img file produced at the end:

Reading c=0-79:h=0-1:step=2 revs=2 (MD2D double sided double density 48TPI disk)
Format ibm.360
T0.0: IBM MFM (9/9 sectors) from Raw Flux (88102 flux in 333.71ms)
...and so on, all the same...
T39.1: IBM MFM (9/9 sectors) from Raw Flux (75989 flux in 333.73ms)
** FATAL ERROR:
'NoneType' object has no attribute 'decode_raw'

Is this a bug or am I doing something wrong? Same Newtronics/Mitsumi D509V2 drive, same 1.8 software, using the GreaseweazleGUI as indicated on the wiki page.

Almost certainly a new bug. Please can you try v1.7?

[keirf]

Also please get a backtrace by adding --bt to your command line between gw and read. gw --bt read ...

[keirf]

I think it's been broken in this way since v1.5 (released 4 Jan) and it's because your trackspec is wrong. You need this on the command line:

--tracks=step=2

Don't change the cylinders! These are automatically set correctly for the format (ibm.360) and are in "logical"/disk cylinders, not drive cylinders! You are actually trying to read cylinders 40-79 off the disk, and of course they don't exist and, due to a fairly recent bug, it actually crashes the gw read command. I will get that fixed but it's less critical than I first thought.

[Bzzz]

So that worked...

Maybe this can be added as an explicit MD2D example on the wiki page? I looked around quite a bit to find correct settings for non-HD disks and ended up trying a bunch of settings, since stock ibm.360 (not using step=2) does produce errors with this HD drive, e.g.

Yes the docs are bad, they need a bit of TLC. New ticket #280
