Hi,
I have a bad disk to (dd)rescue.
It recently stopped showing up on my live-linux(OSC).
I’m trying to read it with my macbook(Sonoma).
I’m wondering why Ddrescue thinks the size to be 9223 PETAbytes.
Can I do something that it would understand the real size of this disk?
I installed Ddrescue through Homebrew.
If you look at “current sector” might be self explanatory why Ddrescue can’t
read that sector…
