testdisk ('bad' name!) isn't testing a physical hdd; it's looking for LVM clues! From #8: read:

That is excellent! The result that I colored "Red" is your LVM volume right where it should be in the extended partition, and with the correct size. Those CHS addresses work out to starting LBA 501760 and ending LBA 209713151. You can either select that partition for recovery and let testdisk write out the repaired partition table, or else use fdisk to create a logical partition with those starting and ending sector numbers. That should be all you need to do.

Which command should I use?
What should I do to solve?
solution: do I recover the disk?
solution: LVM been to identify the disk?
I do not understand English more
I would be glad if you give commands for simple solutions.
thank you |

Since you are unfamiliar with the commands, this is the simplest way. First, copy and paste the text below to a file named parts.out:
Code:
label: dos
device: /dev/sda
unit: sectors
/dev/sda1 : start= 2048, size= 497664, type=83
/dev/sda2 : start= 501758, size= 209211394, type=5
/dev/sda3 : start= 499712, size= 2046, type=83
/dev/sda4 : start= 209713152, size= 838862848, type=8e
/dev/sda5 : start= 501760, size= 209211392, type=8e
Then, run the command
Code:
sfdisk /dev/sda <parts.out
That should repair your partitioning. The LVM volume should now be seen properly. |

This is the fundamental problem with Linux. There are over 100 distributions, each with its own versions of tools. I'll have to download Ubuntu 14.04 and see what version of sfdisk it uses and what it will accept. You can try just removing the "label: dos" line from that file and trying again.

It works fine for me with that same version of sfdisk in xubuntu 14.04. The only way I could duplicate your result was by deleting the newline at the very end of the file. Make sure one is there. If that doesn't fix the problem, to prove that the file is not corrupted post the output from "hexdump -C parts.out"
