Old and unsupported device but this can be useful if your HDD fails.
I managed to replace the original HDD with this IDE emulator using MicroSD:
Installation utility won't recognize the device anymore but you can manual-install rockbox (maybe it is using some VID-PID that changes replacing the HDD ?).
The only issue is that, removing the original HDD, the torx screw won't work anymore because they go inside the original HDD screw-holes.
The original HDD was still working if connected to USB but the original fw won't load anymore. Replacing the HDD with the above adapter and a 16GB microSD makes everything in a working state again.
I used a virtual machine [VM Ware] with Windows XP for testing (drivers for Windows > XP seem to not exist).
