It is my understanding the raw IMG is read/write supported on newer firmware, yet I have a Mirage which can read from IMG yet only HFE is read/write. I know that IMG is read/write under other Ensoniq models such as the EPS16.
The internal configuration on the Gotek/HxC is set to "write enabled", and the FAT permissions for the IMG file is not read-only. Again, the HFE can be written to, so this should not be a configuration issue, and it cannot be a file attributes issue either.
It shouldn't be an issue of unknown geometry either because the IMG can be read just fine. So why no write support?

Re: Ensoniq Mirage -- Write to IMG unsupported
Indeed write is supported for the Ensoniq Mirage too.
