Unable to find data in Corrupted external hard disk

#1 Post by nnazs » 19 Aug 2017, 07:56

Hi there,
My 1 Tb LG external Hard disk is asking for format when connecting it to computer(Windows 7). When I have tried to recover data with TestDisk, it is only showing few folders. Can you please guide me how can I search for all folders in the HD. I am a newbie.
The Hard disk has photos of my baby.
Please help me in recovering precious memories of my baby !!!
Please find logs below (There were hundreds of line -"file_pread(5,1,buffer,95475848(5943/24/42)) ReadFile Data error (cyclic redundancy check)" So I deleted most of them).

Re: Unable to find data in Corrupted external hard disk

#2 Post by cgrenier » 19 Aug 2017, 13:29

You should clone the disk to a new empty one using ddrescue as described in https://www.cgsecurity.org/testdisk.pdf
Read the chapters "Creating a live USB" and "DDRescue: data recovery from damaged disk".
Once it's done, remove the original disk and try to recover your data from the clone. If TestDisk doesn't list more directories, use PhotoRec to recover the pictures (Select [Whole] instead of [Free] after selecting the partition).
