Re: 2.8" QD Disk Emulation
Since the application is free you might have use for the capture itself, then you can scroll through it at will. It think it allows for measurements directly inside the app.

Re: 2.8" QD Disk Emulation
I don't see anymore the short ready time similar to this :

Can you reproduce it ?

Re: 2.8" QD Disk Emulation
Ok thanks a lot, i will test the app.
Re: 2.8" QD Disk Emulation
I will mail the exports as well, just to make sure.
Re: 2.8" QD Disk Emulation
Thanks.
Attached an blank image matching with your captures. The total track length is definitively shorter than i expected : 7.23s vs 8s. These drive seems to rotate faster than the others found in others machines.
EDIT : Removed !
Re: 2.8" QD Disk Emulation
Sadly, still a Verify Error on that one.
Also, I can't read it back (I/O Error 2).

Re: 2.8" QD Disk Emulation
please share the image and retry with the attached image.

Re: 2.8" QD Disk Emulation
0001 I can read back again (still verify error)
Both images attached

Re: 2.8" QD Disk Emulation
My actual drive has a brand new drive belt (so no sagging as older belts might do), I'm not sure that influences the speed. Anyway, as there's no way to calibrate these drives I'm guessing speeds will vary anyway.
Re: 2.8" QD Disk Emulation
Try with the attached image and share them once done.
EDIT : roland_qd.zip (2) Removed !
May be interesting to make some trace with the gotek to compare the behaviour ?

Re: 2.8" QD Disk Emulation
I'll look into that, I need to make something to make it more easily interchangeable (I soldered 9 wires directly to the drive now)
Results attached. Both give verify error, but both are readable.

Re: 2.8" QD Disk Emulation
I think that my ready signal is a little shifted versus the data position. I will check this this evening against the logic analyser capture.
Re: 2.8" QD Disk Emulation
a firmware with a trick : I don't deassert the ready signal during the write until the WG is disabled.
EDIT : Removed !
try it on the last images.

Re: 2.8" QD Disk Emulation
Trick firmware results. Verify error on both and unreadable (I/O Error 2)
