Re: [Bug-ddrescue] Help

[Adrien Cordonnier]

Hi Kristian,

You likely have defective hardware in your own computer (bus adapter or
disk controller). I advice to complete the rescue with a reliable computer
such as your friend computer, continuing with the map file from your
friend's computer: if the adapter or controller is damage, the data
recovered with your own computer may have been altered during copying.
Don't forget to identify and change the defective part, it will damage your
next disk.

Good luck,

Adrien
