However, your documentation doesn't appear to explain how to append data to an existing file.
That is part of why I stated that it may be easier for someone to write a shell script to do the main work and just do calls to hddsupertool using the read pio script for the reads. Hddsupertool cannot directly append one file to another, but if you look at the WRITEBUFFER command it has a file offset parameter, and an example command to write a second sector to a file. If you want to append a file to another file then use Linux shell (bash) commands, which can easily be looked up online. Plus hddsupertool can perform shell commands from within the script as needed with ‘CALLCOMMAND’ .
Code:
‘WRITEBUFFER’
Write the buffer or part of the buffer to a file. The format is "WRITEBUFFER filename bufferoffset fileoffset size", where filename is the name of the file to write to, bufferoffset is the byte offset of the starting point in the buffer, fileoffset is the byte offset of the write point in the file, and size is the size in bytes to be written. If the file does not exist it will be created. This will overwrite the designated data in the file, but will not erase any other data in the file, meaning you can keep adding data to the file at different offsets.
# write the first 512 bytes of the buffer to the file named image.bin
WRITEBUFFER image.bin 0 0 512
# write 512 bytes to the second sector of the file
WRITEBUFFER image.bin 0 512 512
