I have a 1TB external HDD. There were two partitions on this HDD. My first partition was a 60 GB partition and the second partition was a 871 GB partition. I did not need the data on the first partition, but I need the data on second partition. Last night I decided to merge these two partitions using gparted.
After I tried to merge these two partitions, gparted was merging these two partitions but it was taking a long time, 3 hours. but after about 2 hours the OS, Linux mint 15, stopped working and I could not do anything. I uploaded a video from this situation here. I could only move the mouse cursor.
But I think gparted was still doing its job, so I did not power off my laptop. I let the gparted do its job and I went to bed. When I woke up after 5 hours, the screen was completely black and I could not do anything and the external HDD was silent, as it was unmounted. After a shut down everything was ok But the OS, Linux mint 15, can not mount my external HDD. I get this error.
Here is a shot of gparted from my external HDD after the merge. Right now there is only one 931GB partition which I can not access.
I prefer to some how recover the data which I had on the 871GB partition before merging. I have a backup from this data, but I prefer to recover it. I think if I could somehow know what happened that my system was not responding, I might find a better solution.
Should I recover the partition table? If I recover the partition table will I have my data? How can I know what really happened that the system was frozen?
Edit 1: The 60GB partition was in ext4. The 871GB partition was in NTFS. Before merging these two, I deleted the 60 GB partition and reformatted it, most probably to NTFS but I am not sure and I can not remember.
Edit 2: The partition table for the HDD was GPT and not MBR.
Edit 3: Since the Testdisk command did not help, and it could not recover the partition table for the 871 GB drive. I did what the error told me to do.
I used the
chkdsk /f command in windows to check my drive. I do not know why I was asked in the error to restart twice. But after the
chkdsk /f, it took about 45 minutes, I shut down the windows system and rebooted but in the windows I could not access my drive.
Then, I connected the drive to my linux system and I had all of my files in the correct order and correct name.
Now I have another problem. Although I can access all folders, but some files are corrupted. I can not see most .jpg files and most video and pdf files. I can play some mp3 files but the content is not related to the name of that mp3 file. I will try to fix this problem.
