Hi everybody.
Three days ago, I accidentaly killed my wife's Windows partition on our Mac.
To recover the data, I discovered PhotoRec and TestDisk.
Wonderful softwares, easy to use and powerful.
But really, really slow.
It took 20 hours to scan the entire 250 Gb Windows HDD.
At the end of the research, I closed every softwares, cause the CPU's temperature was really high, 95°C~203°F, and the fan was running harsh.
Didn't change anything.
I took a look at the activity monitor : a process photorec was still running, at 100% CPU charge.
I also took a look at the thermal sensors : the CPU was permanently altenating between two cores.
This part, I think, is an OS behaviour : OS X alternates cores to prevend overheating.
Had to kill the photorec process myself, and the system returned to normal state.
----------------
Today, I made a new research, and same player shoot again, same score : 95°C~203°F, CPU full charge even when PhotoRec is closed, etc...
Apparently, PhotoRec bugs when the CPU is stressed.
I send a mail to PhotoRec creator/maintainer,
Christophe GRENIER.
So I just wrote this thread for information, or just in case someone has an idea/wants to help.
