dd & mount

Long time no blog. As a note to myself, so I won't forget anymore:

When you pull a full disk image (sda.disk) with dd and it contains more than one partition just do the following (multiply times 512 bytes the sector start, mount will figure the rest out by itself):

bazz:/mnt/ntfs/# sfdisk -l -uS sda.disk 
Disk sda.disk: cannot get geometry

Disk sda.disk: 9729 cylinders, 255 heads, 63 sectors/track
Units = sectors of 512 bytes, counting from 0

 Device Boot    Start       End   #sectors  Id  System
sda.disk1            63 156296384  156296322   7  HPFS/NTFS
sda.disk2   *  19438650  19470779      32130   e  W95 FAT16 (LBA)
 start: (c,h,s) expected (1023,254,63) found (1023,0,1)
sda.disk3             0         -          0   0  Empty
sda.disk4             0         -          0   0  Empty
bazz:/mnt/ntfs/# mount -oloop,offset=$(echo "63*512" | bc) sda.disk /mnt/foo
