You should succeed by creating the loopback-device with an offset to the desired partition. A plain old mount looks for filesystem information at offset 0, which in your case apparently points to some bios boot information, but not to the desired ext4 fs.

The problem is that there are multiple partitions in your image. Now, the image's Linux partition is mounted at /media/sdcard and the root user can edit its files.įinally, when you're finished: sudo umount /media/sdcard Sudo mount -o loop,rw,sync,offset=48234496 printer_v5.img /media/sdcard Now, manually multiply the start sector * sector size to get the offset bytes that the mount command needs. Below i will show my workflow to mount a forensically acquired hard disc drive or partition image in Expert Witness format on an Linux system. I/O size (minimum/optimal): 512 bytes / 512 bytesĭevice Boot Start End Sectors Size Id Type Logical evidence files are typically created after an analysis locates some files of interest, and for forensic reasons, they are kept in an evidence grade container. In Gnu / Linux we have excellent ways to manage. Sector size (logical/physical): 512 bytes / 512 bytes Although ISO 9660 is set as the format of read only it is possible to modify these files with some programs. Note the sector size in bytes (512 in this case see line 2 below) and the Start sector of the partition (94208 for the Linux partition see the last line below). Here's the process: fdisk -l raspberry_pi.img Sadly I've never been able to find a Linux tool that automates that. And mount it: mount -o ro -t auto /dev/mapper/loop1p1 /where/to/mount. ls -l /dev/mapper file -sk /dev/mapper/ finally check that it is a FAT32. Select the drive and continue the process will run automatically from here. losetup /dev/loop1 image.iso kpartx -av /dev/loop1 Output will be like add map loop1p1. You have to detect the offset of the partition and mount it specifically. DiskInternals Linux Reader - select Containers DiskInternals Linux Reader - select the disk image DiskInternals Linux Reader - Mounted disk 6. That means it starts with a bootloader and a partition table. img file is not an image of a partition, but of a whole disk. Here's the full process, based on the answer here: You need to make sure that your current user directory has read and write access to your operation sudo mkdir -p /tmp/test & sudo mount -o loop,rw,sync image.img /tmp/test
