I cannot mount the image. The image itself is not a filesystem. It is the Whole Disk image, which contains the NTFS partition. The losetup command does accept an offset value. However, these values have to be expressed as integers of KiB or MiB or GiB ...etc. The NTFS partition starts at sector 63, which is not a multiple of 1KiB (1024 Bytes). If the losetup command could accept an offset stated in sectors or in an arbitrary integer number of bytes, the losetup could be used to access the partition within the image and mount it. Interestingly enough, the kernel loop driver looks at the offset as a number of sectors! Cheers, JD
