I've just backed up two partitions with dd under linux, so I have raw partitions images: part1.img and part2.img. Additionally I've backed up the disk's MBR (first 512 sectors of the disk) and some text info ('fdisk -l' /dev/sdb).
fdisk -l /dev/sdb said before I did dd: Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x7d22da32 Device Boot Start End Blocks Id System /dev/sda1 * 1 196 1574338+ 27 Unknown /dev/sda2 197 19457 154713982+ 7 HPFS/NTFS
It's a standard laptop disk so part1 is a system recover partition. Part2 is the Windows Vista bootable partition.
I've then converted part2.img to part2.vdi (VirtualBox disk format). I've attached part2.vdi to an existing virtual XP machine and I can browse it and delete what I want (part2.vdi being second partition, not booting from it).
However the problem is when I want to attach the part2.vdi to the virtualized Linux system and want to mount it.
now fdisk -l /dev/sdb says (sdb being part2.vdi here, so not whole disk as before): Disk /dev/sdb: 158.4 GB, 158427250688 bytes 255 heads, 63 sectors/track, 19261 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x2052474d This doesn't look like a partition table Probably you selected the wrong device. Device Boot Start End Blocks Id System /dev/sdb1 ? 410 119791 958924038+ 70 DiskSecure Multi-Boot Partition 1 does not end on cylinder boundary. /dev/sdb2 ? 121585 234786 909287957+ 43 Unknown Partition 2 does not end on cylinder boundary. /dev/sdb3 ? 14052 14052 5 72 Unknown Partition 3 does not end on cylinder boundary. /dev/sdb4 164483 164486 25945 0 Empty Partition 4 does not end on cylinder boundary. Partition table entries are not in disk order
Where's the catch? Why does Windows "mount" partition automatically (don't see weird entries) and I can access data but under Linux I have problems with partition table entries? How can I solve it without losing data/partition integrity?
