Write .hdf file to SCSI drive for Amiga?

Is there any way to write an existing .hdf file to a SCSI drive? The tricky part is that my only machine with a SCSI port is too old to run an emulator, so I'm hoping to write the file using the unix "dd" command or something similar.

dd works but unless hdf size is exactly same as hd (exact same amount blocks),
hdtoolbox (or any other partitioning program) may get confused and in worst case corrupt your partitions if used after transfer.

I haven't tested but I am sure something bad can happen = no support in WinUAE

HDToolbox does nothing like this. HDInstTool is the only program which corrupts partitions. HDInstTool is evil.

It's completely safe to write a HDF to a bigger HDD. You just waste the additional space. And you must not use HDInstTool on it.

You need to make a partitioned HDF with an RDB first. With an old-fashioned big-floppy-disk-HDF it does not work. Make a new HDF. In WinUAE click on "Enable RDB Mode", in E-UAE set the values for Surfaces, Sectors and Reserved all to 0. Then run HDToolbox with uaehf.device as driver. Create a partition, format it and copy the files from the old-fashioned HDF to the new one. Then write the new HDF to your HDD with dd.

Thanks for the help; the partitioned HDF with RDB did the trick!
