Но RAW то он запишет. Формат для Неона по идеи должен подойти от WD1010.

Только там именно такого контроллера нет:

mfm_emu_powerfail_v1.34/mfm/inc/mfm_decoder.h
...
   // Track format
   // Update mfm_controller_info list below if enum changed.
   // ORDER IN THE TWO LISTS MUST MATCH
   // TODO, replace this with pointer to CONTROLLER entry
   enum {CONTROLLER_NONE,

      CONTROLLER_CROMEMCO,
      CONTROLLER_VECTOR4,
      CONTROLLER_VECTOR4_ST506
   } controller;

Причем не все контроллеры полноценно поддерживаются: собрал что мог без TI-шной железки (только mfm_util и софт линк ext2emu) и наверняка делаю что-то не так, но вот получаю такое сообщение:

./ext2emu --heads 4 --cylinders 615 --extracted_data_file st225ext --format WD_1006 --emulation_file st225.emulation
Not yet able to process format WD_1006

Там так:

   if (mfm_controller_info[drive_params.controller].track_layout == NULL) {
      msg(MSG_FATAL, "Not yet able to process format %s\n",
         mfm_controller_info[drive_params.controller].name);
      exit(1);
   }

А не нулевой указатель там у "WD_3B1" "DTC" "DTC_256B" "DTC_520_256B" "DTC_520_512B" "OMTI_5510" "Seagate_ST11M" "MVME320" "Symbolics_3640" "NorthStar_Advantage" "Cromemco"... Ну указываем другой формат:

./ext2emu --heads 4 --cylinders 615 --extracted_data_file st225ext --format WD_3B1  --emulation_file st225.emulation
At cyl 0
At cyl 1
...
At cyl 610

На выходе получился практически такого же размера файл st225.emulation как и st225 (51286301 против 51286213)

В общем нужно или искать подходящий из имеющихся контроллеров, либо дописывать описание неоновского контроллера.


Что касается предоставленного образа st225, то там чаще всего выбирался контроллер Elektronika_85 (но это не помогает - bad crc сплошные):
