@icescout27 you can disable the compression in 1.5.7.
That said it isn’t quite a dd raw image per say as it’s not using dd in its native form. It’s using partclones imager format which is still a raw copy, just not from dd. The reasoning for this is then our scripts would simply call partclone.restore to place that image on disk regardless of type (raw, btrfs, ntfs, ext, etc…)
If you really need a true sector by sector you can manually run a dd instance if you know how.
Typically, though, fog isn’t really intended for forensic usage.as we typically are capturing images to be used for mass on other systems. This of course is not to say fog couldn’t be used for this, just it’s not something we are familiar with as part of our product.
If you need any help I’m sure we can provide some assistance.
