Unit?  [compact]? B

Model:  (file)
Disk /home/one/sdc.img: 32085377024B
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start     End           Size          Type     File system  Flags   
 1      4194304B  32085377023B  32081182720B  primary  fat32        boot, lba

 

  1. The key things above are to change the unit to bytes
  2. Divide the bytes of the starting point of your partition by 512 (because that's how many bytes per sector you get normally when dding a device)

With dd set the blocksize: bs=512 (since our blocksize with this image is 512).  The count will be the size 32081182720 bytes/4= 32081182720

So 4194304 bytes/512=8192 (is our start or skip=8192 with dd)

dd if=sdc.img skip=8192 bs=512 count=8020295680 of=sdc1.img

After that it's a matter of mounting it:

mount -o loop sdc1.img mountlocation
