Recover empty space from NTFS partition in .img file
I have a snapshot of an old computers harddisk saved as an .img file. I have mounted it with sudo mount -o loop,offset=209715200 /usr/nasShare/Backups/hpster.img /mnt/tmp which works beautifully.
Here is the layout of the disk: (result of sudo fdisk -l /usr/nasShare/Backups/hpster.img)
Device Boot Start End Sectors Size Id Type
/usr/nasShare/Backups/hpster.img1 * 2048 409599 407552 199M 7 HPFS/NTFS/exFAT
/usr/nasShare/Backups/hpster.img2 409600 937510911 937101312 446.9G 7 HPFS/NTFS/exFAT
/usr/nasShare/Backups/hpster.img3 937510912 976560127 39049216 18.6G 7 HPFS/NTFS/exFAT
/usr/nasShare/Backups/hpster.img4 976560128 976771119 210992 103M c W95 FAT32 (LBA)
I am trying to recover any relevant files, so that I can delete the image, but am faced with an issue of not enough free space on the host system. I gather that the issue is that the "empty" space on the device is not empty in the file.
According to du -h /mnt/tmp I am using 252G
I have read several articles like https://unix.stackexchange.com/questions/199673/modifying-files-inside-a-snapshot-qemu-img-file and https://unix.stackexchange.com/questions/278877/shrinking-raspberry-pi-sd-img-via-ubuntu-server-cli
and the gist of it seems to be:
umount, resize, fdisk/parted, partprobe, fsck, and mount to check all is ok
But I am unsure whether these tools will work on an NTFS partition.
Update:
I have read an article about resizing an NTFS partition, but when I attempt running sudo ntfsresize --info /usr/nasShare/Backups/hpster.img2
I get the following error:
ERROR(2): Failed to check '/usr/nasShare/Backups/hpster.img2' mount
state: No such file or directory Probably /etc/mtab is missing. It's
too risky to continue. You might try an another Linux distro.
