I've recovered a complete NTFS disk with ddrescue in Linux. The catch is I didn't just rescue the partition (sdX#) but complete disk (sdX) with partition table.

It's really easy to mount disk partitions as loopback devices, but is there a way to mount a partition of a complete disk image in the same way? I can write the image to another disk but I feel it shouldn't be necessary.

If you imaged the whole drive you can use offset option with mount command. mmls (from The Sleuth Kit) can show partitions within an image

$ mmls image -b
DOS Partition Table
Offset Sector: 0
Units are in 512-byte sectors

     Slot    Start        End          Length       Size    Description
00:  -----   0000000000   0000000000   0000000001   0512B   Primary Table (#0)
01:  -----   0000000001   0000000031   0000000031   0015K   Unallocated
02:  00:01   0000000032   0001646591   0001646560   0803M   DOS FAT16 (0x06)
03:  00:00   0001646592   0002013183   0000366592   0179M   DOS FAT16 (0x06)

Mount the DOS partition starting at block 32:

sudo mount -o loop,offset=16384 image mnt

(32 multiplied by 512 byte blocks = 16384)

For mounting a typical NTFS partition created by Windows use:

sudo mount -t ntfs -o r,force,loop,offset=32256 image mnt

(63 multiplied by 512 byte blocks = 32256)

Should that really be -o r,... and not, say, -o ro,...? –  Michael Kjörling Mar 7 '13 at 9:55
    
Wow. Looks nifty! Thanks a lot. –  SilentStorm Mar 7 '13 at 15:20
