How do you guess disk geometry
Posted: 31 Oct 2016, 16:46
I am trying to recover data from a disk that had been improperly plugged into an external enclosing. When using testdisk (on entire disk), I've tried supplying several disk geometries.
If I change anything from the default geometry, testdisk detects it goes against what's written in my partitions, so I guess the default is OK. That is true except for number of cylinders.
How can I guess the correct number of disk cylinders? I've tried default value, some basic arithmetics to match disk size, and found no datasheet online (my disk is WD30EZRX, if you're luckier than me), with no results yet..
