If you don't, you'll have to have a disquette reader connected to your computer. You can change your disquette reader inside the MPC by a SD card reader, which will save you a ton of time

Air is no longer supported by Adobe but you can still download their latest version. If you do have one, you may want to load sounds in a much quicker way, because, you know, loading sounds one by one has never been the easiest way.

img files as well as mountpoints, either vFloppies or actual hardware floppy drives.If no, this software won't be of any help.

I won’t go into implementation details but the code is hopefully self-explanatory. Using the Kaitai python lib, it was trivial to make a tool that reconstructs those custom long file names and extract the corresponding files following the offset in the file allocation table. I don’t know if it’s reserved as in “reserved for future standard evolutions” or “vendor-reserved” but anyhow that’s how they did it. Turns out the remaining file name after characters #8 is stored in a field called reserved. It even has web editor that allows you to load local files! It comes bundled with support for FAT partitions. That’s then that I discovered Kaitai Struct, set of libraries / descriptor format for parsing file(system) formats.

Haha! The full file names are legible 2 in the file allocation table!īut how is that possible that our previous tools weren’t able to parse them?Īnd how to programmatically extract files with those full names? Reverse engineering: Kaitai Struct to the rescue The next logical step was to boot up an hex viewer/editor 1 and to try to understand what’s going on. So apparently, Akai decided to do something custom instead of vFAT in 1999 even though it was already there since Windows 95. In fact, those commands are pretty smart at determining the filesystem type by themselves and setting it manually (using -t vfat) didn’t help. So I just thought that the MPC simply uses vFAT and that I was using the wrong arguments when using mount / mtools.

This feature is called LFN (for Long File Names) and uses “dummy” interleaved file records for storing those longer names. vFAT or not vFATĪfter googling a bit, I discovered that something called vFAT allows having file names longer than 8 characters on any FAT partition. $ sudo mdir -i $(( 4 * 1536 * 1024 )) ::īut when attempting to extract those files, neither of Floppy Emulator, mount + cp, mtools’ mcopy or usbfd will allow getting (at best) a single of those files. We can directly mount a virtual floppy to see its content: Under Linux, we have a wide range of possibilities.

There is also an official Gotek software which is said to mostly not work.

Mounting floppiesĭepending on your OS, there are several solutions for mounting virtual floppies from a Gotek-formatted USB drive on your computer.įor Windows, the best solution is Ipcas GmbH’s Floppy Emulator that works fairly well but needs to be executed as an admin on recent Windows 10 versions. I don’t know if this higher value corresponds to rounding due to fixed sized blocks / segments / whatever or if I’m actually truncating data. Floppies have a size of 1440 kB but we need to jump 1536 to go from one to another. NB: I’m not 100% sure about the value for count. $ $ # in any case, we can verify we have a valid image using mdir from mtools $ mdir -i ~/Documents/backup_gotek_ $MY_FLOPPY_ID.img :: $ # extract an image of a single vFloppy from it $ dd if =~/Documents/backup_gotek_all.img \ of =~/Documents/backup_gotek_ $MY_FLOPPY_ID.img \ skip = $(( 4 * 1536 * 1024 )) bs =512c count = $(( 1440 * 1024 )) \ iflag =skip_bytes,count_bytes conv =noerror $ $ # make an image of a whole USB drive $ sudo dd if =/dev/sdb of =~/Documents/backup_gotek_all.img ~/Documents/backup_gotek_ $MY_FLOPPY_ID.img
