## Acquisition
### DD
```bash
#This will generate a raw copy of the disk
dd if=/dev/sdb of=disk.img
```
### dcfldd
```bash
#Raw copy with hashes along the way (more secur as it checks hashes while it's copying the data)
dcfldd if= of= bs=512 hash= hashwindow= hashlog=
dcfldd if=/dev/sdc of=/media/usb/pc.image hash=sha256 hashwindow=1M hashlog=/media/usb/pc.hashes
```
### FTK Imager
You can [**download the FTK imager from here**](https://accessdata.com/product-download/debian-and-ubuntu-x64-3-1-1).
```bash
ftkimager /dev/sdb evidence --e01 --case-number 1 --evidence-number 1 --description 'A description' --examiner 'Your name'
```
### EWF
You can generate a disk image using the[ **ewf tools**](https://github.com/libyal/libewf).
```bash
ewfacquire /dev/sdb
#Name: evidence
#Case number: 1
#Description: A description for the case
#Evidence number: 1
#Examiner Name: Your name
#Media type: fixed
#Media characteristics: physical
#File format: encase6
#Compression method: deflate
#Compression level: fast
#Then use default values
#It will generate the disk image in the current directory
```
## Mount
### Several types
In **Windows** you can try to use the free version of Arsenal Image Mounter () to **mount the forensics image**.
### Raw
```bash
#Get file type
file evidence.img
evidence.img: Linux rev 1.0 ext4 filesystem data, UUID=1031571c-f398-4bfb-a414-b82b280cf299 (extents) (64bit) (large files) (huge files)
#Mount it
mount evidence.img /mnt
```
### EWF
```bash
#Get file type
file evidence.E01
evidence.E01: EWF/Expert Witness/EnCase image file format
#Transform to raw
mkdir output
ewfmount evidence.E01 output/
file output/ewf1
output/ewf1: Linux rev 1.0 ext4 filesystem data, UUID=05acca66-d042-4ab2-9e9c-be813be09b24 (needs journal recovery) (extents) (64bit) (large files) (huge files)
#Mount
mount output/ewf1 -o ro,norecovery /mnt
```
### ArsenalImageMounter
It's a Windows Application to mount volumes. You can download it here
### Errors
* **`cannot mount /dev/loop0 read-only`** in this case you need to use the flags **`-o ro,norecovery`**
* **`wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error.`** in this case the mount failed due as the offset of the filesystem is different than that of the disk image. You need to find the Sector size and the Start sector:
```bash
fdisk -l disk.img
Disk disk.img: 102 MiB, 106954648 bytes, 208896 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00495395
Device Boot Start End Sectors Size Id Type
disk.img1 2048 208895 206848 101M 1 FAT12
```
Note that sector size is **512** and start is **2048**. Then mount the image like this:
```bash
mount disk.img /mnt -o ro,offset=$((2048*512))
```
