How to perform sector-by-sector copying of MHDD?

Question

Hard disks

Good afternoon.
There is the following problem - there is a hard drive that is only accessible from Victoria and MHDD.
Data needs to be restored. MHDD has the function of sector-by-sector reading to a file, but this file is created in the MHDD directory, so restoring 320 gigabytes to a bootable USB flash drive or to a ramdrive is not an option.
Tell me a way in which you can remove data from a disk or an option to install MHDD on an internal drive.
