Well I pretty much believe that this was the standard block size of the tool I used in order to create the RDB. I think it has been Media Toolbox + the engine behind it, from AmigaOS 4.0 (not 4.1) or so. DOS- Type JXF points to JXFS, an AmigaOS 4 only filesystem that meanwhile has been deprecated by AmigaOS upstream. Maybe HDToolbox + hdwrench.library by Joanne (AmigaOS 3.5/3.9) would have set it up differently. Anyway: It works like this in AmigaOS 4 without any issues. With 512 Byte Blocks. I think it is good that Linux does not create data corruption when writing to disks that work just fine in AmigaOS. Especially as those using AmigaNG machines like AmigaOne X1000/X5000 or Acube Sam machines may dual boot AmigaOS and Linux on their machines. Thanks again for putting together a patch. Thanks, -- Martin
