Hi Peter, Thank you for your interesting explanation, I was simply not aware of the fact that QL-SD already uses an image file on a FAT32 formatted SD card. And indeed it would be very interesting to have a similar approach for Qubide IDE hard disks which would be the solution of all the last discussions (using Wolfgang utility).
Just for curiosity (for sure discussed many times in the past): why the QL-SD interface is not compatible with GD or SGC?

DD can convert a raw media (Qubide formatted in this case) to an image file. But QL-SD already has the Qubide partitions in an image file! It does *not* have Qubide raw media, although that would have made it easier to get a working driver. The whole reason I initially wrote the QL-side FAT32 code, is to save the step of converting raw media to image files. Or in other words, the basic concept of QL-SD is *not* to need tools like DD. On QL-SD you can directly read the Qubide image file from a PC, for instance with QxlwinReader or an emulator. By the way, the same approach could also be taken for Qubide IDE harddisks! The IDE harddisk (or compact flash, etc.) could be formatted in FAT32, and then have Qubide inside an image file like QL-SD. That way, DD would no longer be needed. Now that the QL-side FAT32 code is there, it could be re-used. Maybe Alain could comment on this? The only remaining issue would be to convert old "raw" Qubide harddisks once. > I think maintaining compatibility and support of native QL hardware > should have some priority. I agree, insasmuch retro-computing becomes pointless if it lives only on emulation. Whereever I saw people returning to the QL in the recent years, it was hardware-related.
