Please help!!!!! Recovery of Linux partition

#1 Post by Jrock » 23 Apr 2015, 11:40

I REALLLY need help recovering a Linux partition. I do have a logfile. I had a Linux partition and a Windows partition. Linux is what I need to recover. At first attempt, I ran testdisk analyse. When it returned with one result-Linux- I selected this and wrote table, without pressing P to list files. This was my first time using testdisk and I was excited when testdisk returned a result showing Linux. Thinking everything is fine, I rebooted and attempted to boot Linux. Nothing showed up. I opened gparted to look at the partitions. I now have one ext4 partition, and two unallocated partitions. From top to bottom, in this order: unallocated, ext4 Linux, unallocated. Before I ran testdisk and had working partitions: Linux, Windows 7.
I ran testdisk again, and did deeper search. Results returned with six D Linux and one hpfs-ntfs Windows. Linux's results are listed first, and Windows last. After pressing P for Windows, the root folder shows. Again, Linux is what I need.

Here the info from logfile. I really thank you for your help!!!!!

Didn't find the result of Deeper Search.
Did you interrupt your scan running Deeper Search?

Hello hello.Here is the testdisk logfile from new test. I could only use testdisk 6.14 in knoppix. I couldn't get testdisk 7.0 to work. After I extracted folder, I sudo testdisk-7.0 /testdisk_static, and get this message in terminal,"command not found. How do I install testdisk. 7.0?
I regarding the logfile, I don't know what to do next to recover Linux partition. Thanks for your help.

Hello hello. I ran a third test with full analyse, then deeper search. The first testlog I posted was only with deeper search.There are some details I think I should mention. The very first time I ran testdisk, I used analyse. It returned with one Linux partion. I did not check to see if there were any files. I usedthe "write" option. The second time I ran testdisk, I selected the only Linux partition listed using analyse. I pressed P to list files and it shows, "file not found, filesystem may be damaged". So, it looks like I wrote a partition that had no files in it or was damaged. When I open gparted, it shows three partitions: unallocated-464.31Gib, /dev/sda1-931.51 flags=boot, unallocated-467.36GiB. I don't know how to find the Linux partition that contains the filesystem. I don't know how to reverse what I did. New logfile posted below. Thanks for your help.

Hello hello. I sent PM. I will post here too. I was using Linux and Windows 7 before I had this problem. I was using Linux most of the time. As stated in PM, testdisk forum that .png and .jpeg files are invalid when trying to post a screenshot of gparted showing my disks. What file extensions should I use to post screenshot picture?
