Hello Roger, You should first try to run ddrescue as follow:
ddrescue /dev/sdX1 partition1.img partition1.mapfile Change X in /dev/sdX1 to match the disk letter on your rescue system (you can also clone the whole disk with /dev/sdX). Make sure that partition1.img and partition1.mapfile are on a healthy disk with enough space ("same size" disks often miss a few MB to complete the rescue) and preferably not on a NTFS partition (writing may become very slow and prevent rescue completion). You should read ddrescue documentation ( https://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html#Important-advice) but note that you should use specific options only if the rescue does not complete with the base command. Once you have an image, you can analyze it with testdisk ( https://www.cgsecurity.org/wiki/TestDisk). If testdisk cannot recover the partition, you can try to recover the files directly with photorec ( https://www.cgsecurity.org/wiki/PhotoRec).
