The HxC Gotek firmware have been tested on a MD-280 / Akai 612 : This works "out-the-box". :D

I have added the Akai QD format to the HxC QuickDisk toolkit software :

https://github.com/jfdelnero/HXCFE_QuickDisk_Toolkit

You can currently convert your Akai QD disk image to wav. I can easily add the wav->Quickdisk image converter too if you are interested by this feature.
hi there, sorry to bump an old post, but i was wondering if the wav->Quickdisk image converter feature was ever built? I took a look at HXCFE_QuickDisk_Toolkit but there aren't any docs and i unfortunately don't understand C

Sorry for the noob question, but how do you connect pins 1 -> 33 (+ 10) to ground?

Hi Jeff,

I can't convert Akai S-612 and S-700 .QD files to .wav. When I run the program qd_hxcfe_tk.exe with parameter -checkakaiqd on Windows 7 or 10 it prints "Saving inverted MFM track <inverted.INV>", creates empty file inverted.INV, then crashes with exception code c0000005. When i run it on Ubuntu 22.04 it prints "Segmentation fault (core dumped)".
Built on Windows with Microsoft Visual Studio 6.0, on Linux with gcc
Would you share your own build, please?

Thanks

I tried to convert these files: http://zine.r-massive.com/akai-s612-archive/ http://zine.r-massive.com/akai-s700-archive/
I don't have Akai samplers nor a floppy emulator so I would like to extract the samples and use them on my computer in DAW.

Most of these QD files appear to have a bad file header.

I have updated the tool to try to support these QD files :

Hello, Jeff and all!

I'm hoping to replace QD for Famicom(Japanese NES) with Gotek.
I have both QD for Famicom and Gotek. Gotek firmware is for QD.
I worked with reference to the following site.


(1)When USB stick is ejected I can see q-d on the Gotek display.
(2)Gotek's jumper pin is set to MO.
(3)I have wired the QD pins to the appropriate pins on the Gotek.
However, the voltage is zero unless the motor is started,
so I made a dedicated board to connect between Gotek and the Ram adapter.
(4)The app I'm using is named "FAMOS", and it's self-made software by volunteers.
The software is a program for the 6809 and runs on the FM-7(8bit PC).
Furthermore, as hardware, a dedicated board named "FAMOS77" is required
to connect the signal line between the Ram adapter and the FM-7.
Using ``FAMOS'', ``FAMOS77'', and FM-7, I can read and write QD normally.
(5)If I start the motor to write to Gotek it works,
but the data in the USB stick is no change
(6)When the motion is simulating the motion of the motor Gotek's LED
is emitting light. And USB memory access LED is blinking.

Please give me good advice.

Hello All,

I just Acquired an S700 with a GoTek USB Floppy Drive. My very 1st sampler was the S700, which I sold back in the day.
I have tons of samples on QD disk that I am currently trying to restore. Just finding some odd issues:

1) I can load/save/verify from the S700 original QD floppy drive without any issues
2) I can save to the USB floppy without any issues
3) I get "Bad Data Error" when I load or verify from the USB floppy, although the sample still loads

I have firmware "HxCFEUSB_V5_2_1_2a_QuickDisk.UPD" loaded and I'm using the "DSKA0003_Akai_formatted.QD" format.
I also tried previous firmware versions, and the Roland and Blank QD formats, but no luck.

Theses errors are just an annoyance, but I thought I'd mention them in case I'm doing something wrong.

What I would love, is to be able to extract & convert the samples (to WAV) off the QD images.
I already tried using the Floppy Emulation software, but doesn't work (Windows or Mac version). It's actually a very cool application.

MIDI sample dump fails too. I have tried old Windows and even Atari applications (using Hatari emulator) like Sample Wrench but fails to receive MIDI sample. I did succeed in sending (SMP) samples over MIDI to my S700 running on Hatari using Harald Plontke's X7000 software. So there's hope :D

I'll include 2 QD files I saved from my S700 to the GoTek USB floppy. Maybe someone can test on there S700.

Peace

Not sure which model # but I'll check once I return from travels.
No errors appear on the Gotek screen. Just disk # like 000
Any chance there are methods to extract the samples from the QD images?
