not sure if I have the right syntax doing ddrescue,

I am trying to do the 1st 4G or so using


ddrescue -d -r3 -s4000000k /dev/sda4 /index/image.dd

however, I could not do mount on image.dd ,

using mount -o loop,ro /index/image.dd /mnt/img under Ubuntu 15.10

Or is there a correct to take ...

not sure If I could tell testdisk to generate image.dd say,

the 1st 2G , the next 4 G or something like this , in chunks

trying to run testdisk , on a FAT32 partition, it cuts me off beyond 4GB in size..

not sure if there is a way to tell it to create multiple image dd files , each less than 4GB.

so I have an USB drive with FAT32 on to create the DD image target...

on a HP 1TB drive with bad sectors, NTFS.


trying to create an image.dd file, I think it only goes up to 4G in size, and cuts it off...

Not sure if there is a way to do this, telling it to use multiple DD sizes of less than 4G ...
