I made an ISO this way:
sudo partimage save /dev/sdc1 /media/56AE8240AE82191F/Backup/xfcefat.iso
The resulting iso file is very small but when mounted I see that it has correctly preserved the partition information.
The problem is my partition was 8gigs and only had like 100mb of data on it.
I want to fix the partition information on the iso and tell it to think it is only a 500mb partition.
How can I shrink it's partition information?
If it was a usb drive I could do this with gparted and shrink it just fine. But this is an iso file raw copy clone of my disk.
