Topic: Slow disk access and missing files after shrink and move
This is the first time I write in the forum. I've searched for similar questions but couldn't find a related post.
I was about to make a fresh install of my Ubuntu OS, but first, I wanted to gain some free space for my home partition as I had like 60 GB of free space from usr and root partitions. I used GParted from the Ubuntu 16.04 live (GParted 0.25.0). My hdd (500 GB) partitions was as follows:
Dell Backup (107 MB FAT) | Recovery (21 GB NTFS) | windows 7 (107 GB NTFS) | swap (2.1 GB) | root (30 GB ex4) | usr (90 GB ex4) | home (224 GB ex4)
So there were 3 operations that I wanted to perform: first to shrink and move partitions root and usr and then resize the home partition.
After 6 hours aprox, the work was done. Unfortunately, I realize that many files from my home partition were lost and the disk access now it's extremely slow. Slow as my laptop won't boot, and it takes about 10 minutes to start a live version of Ubuntu.
I've used gparted many times in the past, and never had an issue like this before. Here are the results of the process:
I have some questions regarding these problems:
1) First of all, do you have any clue of what would be the reasons of the extremely slow disk access after performing these operations?
2) The several errors shown in the results file could be related to physical problems with the disk? The disk didn't exhibit any symptom of problems in the past.
3) and finally, do you think is there anything I can do to restore the data?
Any help would be very much appreciated.
