Copying files into images?

[jbehrends]

Just picked up a ZuluSCSI RP2040 and had a simple question which I couldn't find asked here so figured I'd ask:

When I have the SD card in my Linux or Windows machine (outside of the ZuluSCSI device), is there any way to mount the .hda/.img files so I can easily copy files into the disk image?

@jbehrends without knowing the filesystem and partition map type contained within the image file, it's not possible to answer that question. Are you using your ZuluSCSI with a classic Mac, or something else?

That is a very fair point! This is being used on an IBM PS/2 and formatted w/ MSDOS 6.22

I have a script that will do this mounting for simplistic use cases

http://www.trinityos.com/HAM/CentosDigitalModes/RPi/usr/local/sbin/mount-disk-image.sh

#!/bin/bash

11/18/22 - dranch mounting szbox disk image

If this doesn't work, run fdisk filename to see if an offset is required

fdisk -l file-image

Look at the START column and if it does NOT start at zero, record this number

Take that number and multiply by the sector size (say 512)

mount -o offset= nps-2010-emails.dd /media/manu/

#Optional Offset size - this is assuming 512 byte sectors
OFFSET=$((264*512))

if [ -z $1 ]; then
echo -e "\nDisk image not provided. Aborting\n"
exit 1
fi

if [ $UID -ne 0 ]; then
echo -e "\nYou must be root. Aborting\n"
exit 1
fi

if [ ! -d /media/image ]; then
mkdir /media/image
fi

if [ -n $OFFSET ]; then
echo -e "\nMounting $1 on /media/image with a offset of: $OFFSET"
mount -o offset=$OFFSET $1 /media/image
if [ $? -eq 0 ]; then
echo -e "Success!"
else
echo -e "Failed"
fi
else
echo -e "\nMounting $1 on /media/image without any offset"
mount $1 /media/image
if [ $? -eq 0 ]; then
echo -e "Success!"
else
echo -e "Failed"
fi
fi

echo " "

Ok! I didn't realize that the images it used were mountable with the standard linux mount command! That's great news, I'll give this a try a littler late this evening! Thanks for the help!

Well, FAT/DOS MBR formatted images are. It depends on the partition table format and the filesystem contained within the image file, but yes, in the case of FAT-formatted images, Linux makes it trivial to mount these sorts of disk images. Under Windows, you can use something like WinImage, which is shareware.

This worked perfectly in Linux. Thanks for the help!
