I was fixing my partition with GParted and it seemed to work well.

But, my laptop suddenly ran out of power and I didn't realize it, then it turned off while GParted was still running which was at the part it is copying 2MB per second(on /dev/sda8)

Then, I plugged in battery cable and checked. All system seems normal.

My question is:

  • Since there is no important data in /dev/sda8 , will any problems arise because of what happened? I already checked all the data in /dev/sda8, and there is no corrupted data.

Output of sudo fdisk -l:

Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
Units = sectors of 1 * 512 = 512 bytes

Partition table entries are not in disk order

gives no error/warning messages

Theoretical and short answer:
yes, something could have gone wrong (though not very likely in your specific case).

Just to be sure that all is well:
The best thing you can do is running a filesystemcheck on any of the filesystems you have.
(let windows check NTFS, let linux check the ext partitions , etc).
If everything checks out OK and you are not missing any personal/data files, there shouldn't be any reason to worry.

The commandline tool to check the integrity of your linux filesystems is: fsck
The graphical tool for filesystemcheck under ubuntu is: palimpsest

For the Windows side of things (if there is an NTFS partition present), the relevant command from a command prompt would be chkdsk volume /f, e.g. chkdsk C: /f if the drive to be checked is mounted as C:. The /f switch attempts to automatically fix any problems with the filesystem. –  Jez W Jun 25 '13 at 16:39
