external harddisk not accessible anymore
Posted: 10 Jul 2012, 09:41
Hello,
I cannot access my Adata CH94 external usb harddisk anymore. When I try to access it, my pc asks to format the disk (tried in more pc's).
I have run the testdisk tool and attached the logfile to this message.
I have some questions. The tool finds a backup for my partition after Deeper Search . Should I then Load this backup? I am able to view my directories. Is it better to copy the files first before I load the backup?
Maybe I can find an example somewhere how to do this. Please point me to this.
Thank you for your help. I will try to write a tutorial when I am able to fix this.

I don't seem to be able to upload the testdisklog. Here are the important parts (I think)
