nope, the problem is more complicated, I guess you have formatted that QXL.WIN file on a QPC drive. On Q40/Q60 and Atari the IDE bus is connected to the CPU bus in such a way that data comming from the HD appears 16-bit byte reversed as compared when you attach the same drive to PC-ish hardware. Traditionally swapping hard disks was not seen as useful or common enough to compensate this in software, afaics only Linux has an option for it. To make matters more interesting, the bus-order and cpu-order accidentally eliminate each other's effect when 16 bit data is accessed and the drive contains little endian data. To summarise: there is a bus-endian and a cpu-endianness issue. CPU is the same for QPC and Q40/Q60 so you only see the bus-endian issue. If you want to use Q40 hard disks on PC hardware you need to use the 'hdX=swapdata' option (linux) for this drive.. anyone knows equivalent option for WinXX? Richard
