Imager project settings

Imager strategy

You can choose between single-pass or multi-pass imaging. Simply put,

  • choose single-pass for undamaged drive
  • choose multi-pass for damaged drive

For more complex explanation, refer here

Hashing

Select whatever hashes you want computed. In the single-pass mode, data is hashed as it comes from the source. In the multi-pass mode, the data is first copied to the target, then additional pass is made over the target to compute hashes. For more detailed discussion of hashes, refer here.

Bad block filler

Bad blocks are filled with a pattern which can be used later to identify files which have bad blocks in their content by searching for it. If you do not specify a pattern, zeros are used. You can either specify an ASCII text or a pattern of bytes in hex.

Source and target

Source and target may be any of the following:

  • Physical drive, any physical drive visible to Windows. I recommend against USB, though. If at all possible, use SATA instead of USB, FireWire, and whatnot. If for some reason you must use USB, read this explanation of possible issues and quirks.
  • Logical drive (also called volume), or a partition recognized by Windows. This includes unmounted volumes, which have no drive letter assigned to them.
  • Disk image file, any of the following types:
    • raw sector-by-sector image
    • VHD image
    • VHDX image

There are some limitations, though, listed below in no particular order:

  • VHD images cannot be larger than 2TB
  • Logical drives cannot be used as target
  • Size of VHD or VHDX image must be integral multiple of of 2MB. If the source does not match the alignment requirement, its size is rounded up. If hasing is required, the extra space is not hashed.
