I will not have access to a Mac before 10 days, so I am unable to do any test for the moment.
Do you have the problem with both TestDisk and PhotoRec ? 6.13 and 6.14-WIP ?
I wonder if the problem may be linked to a Mac OS X update.

Oops, sorry Christophe. I did not see the reply because it was on page 2.

I'll try those 2 versions in the next day or so.

Christophe,

I was able to try 6.13, but got the same result. I could not find a download for 6.14-WIP, but previously, 6.14 and 7.0 also did not work. And yes, it happens for both TestDisk and PhotoRec.

Were you able to try it on a laptop?

I am really desperate to email you directly. Please help me out on this by telling me is the way I did wrong or could there be another way?


I have a mac book pro and i made a mess recently.
While trying to create a partion for windows in dual boot, i open cmd and execute diskpart > clean and it clean away both windows and mac partition before i backup mac partition.
I saw from online that testdisk had helped people previously that did the same as me. I have not perform any format or any more clean after this step so far.

So i downloaded the executable for testdisk-7.0.mac_intel.tar.bx2 and testdisk-7.0.mac_ppc.tar.bz2
tar -xvf both and run testdisk for both of them.

for testdisk in power pc folder, it shows bad cpu type. so i assume i need to use mac intel
for mac intel it shows "Illegal Instruction: 4"

I have no choice but to contact you. Please help me in my situation. I might be able to make some small donation if you don't mind helping me out.
I have precious memory of photo in mac parition that i cant take out even if i brought it to the recovery store.


Regards,
Paul Phua

Testdisk 7.1 wip? Not yet. How should I proceed? Download the executable for windows?

The question is, how can I run that? I can reach window set up stage and start a cmd, but I am not sure if the thumb drive can be read and run. But I will still go ahead and test that out first
