Code:

SD CARDS USED IN SCSI2SD BOARD******************************To make an image of the card:1. Open a terminal in this directory and use:   sudo dd if=/dev/sdxxx of=SDCard.dat bs=1K count=512K   (N.B. change /sdxxx to the location containing SD card adapter)   This will make a 512MB image, alter to the card ADFS size as necessary2.  The card image has 256 bytes of ADFS data followed by 256 bytes of &FF    bytes - so for a 512MB partition, 1024MB is used on the card.3.  The image file will need to be converted using the "Unpad" code originally    written for CF cards/ADFS 1.53 on and IDE interface, which has been modified    for the SCSI2SD board.  See UnpadSCSI2SD.pl and use as follows:./UnpadSCSI2SD.pl < rawfile.dat > unpaddedfile.dat4. The unpadded image file can then be mounted in ADFSFuse, ADFS Explorer,     etc.  Files may be added by dragging them into the ADFS Explorer window. ISW 24/iv/2016

Code:

#!/usr/bin/perlmy $ch;while (read(STDIN,$ch1,256)){  print $ch1;  # Now read and discard the pad  read(STDIN,$ch1,256);}
