Do we support 4K and 8K sector sizes?
Yes. Sector size should be automatically detected for most image formats, as it would be stored in the image's metadata.
However, the DD/RAW image format does not store sector size. For these images, Forensic Tools detects sector size according to the image's file extension, which may have to be manually changed by the user. The extensions "DD4" and "DD8" should be used to indicate 4K and 8K sector size, respectively. These extensions should be used before the segment number indicator.
For example, if the first segment of your 4K DD/RAW image is "MyImage.001", you would rename it to "MyImage.dd4.001". The second segment would be renamed to "MyImage.dd4.002", and so on.
