How to mount partition/volume images properly in OSFmount?

[User376372]

I assume that the beginning of the section is misinterpreted as MBR or GPT causing the mistake. If it was properly mounted as partition (not disk) this should not happen.

Could you please launch OSFMount in debug mode, by using the command line parameter DEBUGMODE, and send us a copy of the OSFMount.log that is created after mounting the image (located in the same directory as the OSFmount executable).

Hey there,

according to https://www.osforensics.com/tools/mo...sk-images.html partition/volume-images are supported. There is no option to tell OSFmount whether it is a disk or partition, so I assume it does auto-detection?
anyways, If I mount a ~4 TB image of an EXT Partition, the virtual physical disk generated by OSFmount is only 404GB according to several tools. How can I make OSFmount to create a virtual physical drive in the correct size?

Thanks
