Cannot determine partition type

HELP?

uname -a:
Linux jon 3.16.0-10-amd64 #1 SMP Debian 3.16.70-1 (2019-07-22) x86_64 GNU/Linux

It looks like you have done an image of only partition1 not the whole device. Try imaging the whole device instead.

dd if=/dev/sdb of=[output path] conv=noerror,sync

Then try running mmls on the image.

You can probably run fls directly on the image you’ve created as you only have the partition imaged.

$ fls usb-copy.dd
