I've been trying to recover a windows 10 C: drive using Ubuntu 20.04.4 and TestDisk. Drive became RAW for no apparent reason. I created a disk image using dd
:
sudo dd if=/dev/sdb of="/media/jmac150/New Volume/image.dd" bs=4K conv=noerror,sync status=progress
I then ran TestDisk against it.
TestDisk advised that both boot sector and backup were ok. However, when I tried to rebuild the boot sector, it failed with a "Segmentation fault":
Any advice gratefully received.
