I had a 3TB WD Red disk with movies and music in my HTPC(with ext4 filesystem). A few days ago the power supply gave up so I took the disk, put it an external USB case in which I usually have a 2TB backup-disk and attached it to my server running Ubuntu 14.04. I was however unable to mount it since the server claimed it had errors. That didn't feel all to strange as the HTPC had been running when the PSU gave up so I fired up a shell with:
sudo fsck -y /dev/sde
It ran for a while and I could mount the drive when it was finished. Now however it only have an empty 2TB partition as opposed to the ~80% full 3TB partition it had before. I'm letting Testdisk analyze it at the moment. But is there some other way to reverse the fsck changes or should I just take it as a lesson and start the lengthy process of adding my media again?
UPDATE: Not sure I get this right, but gdisk seems to think the partition is still using the full disk:
# gdisk -l /dev/sde GPT fdisk (gdisk) version 0.8.8 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT. Disk /dev/sde: 5860533168 sectors, 2.7 TiB Logical sector size: 512 bytes Disk identifier (GUID): CFAA3FF0-DE38-4FAD-B13B-91811BD71821 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 5860533134 Partitions will be aligned on 2048-sector boundaries Total free space is 2925 sectors (1.4 MiB) Number Start (sector) End (sector) Size Code Name 1 2048 5860532223 2.7 TiB 0700 primary
But if I mount it, it's only 2TB:
# mount /dev/sde1 /mnt # df -h /mnt Filesystem Size Used Avail Use% Mounted on /dev/sde1 2.0T 71M 1.9T 1% /mnt
Not much on it though:
