I did file system repairs on my 475 GB partition on an external USB hard drive. with main(root) directory named xyz. After the repairs by fsck, when I connect it to the computer the partition is not mounted.

How can I get my data back?

The output of "lsblk" with HD attached is :

NAME      MAJ:MIN  RM     SIZE  RO   TYPE    MOUNTPOINT  
sda         8:0     0   149.1G  0    disk
sda1        8:1     0    10  G  0    part
sda2        8:2     0   139  G  0    part
sdc         8:32    1     1.9G  0    disk
sdc1        8:33    1     1.9G  0    part   /cdrom
sdd         8:48    0   465.8G  0    disk
sdd1        8:49    0    18.7G  0    part
sdd2        8:50    0     4.7G  0    part
sdd3        8:51    0   442.4G  0    part /media/ubuntu/356d60dc-80a5-40b4-8a20-117322d45
sr0         11:0    1  1024M    0    rom
loop0        7:0    0   952M    1   loop  /rofs

The output of lsblk without HD is without the details of sdd.

  • Please [edit] your answer to include the output of lsblk with and without the HDD attached. Then leave a comment @fabby – Fabby Dec 28 '15 at 15:05
  • @fabby I have edited the details with output of the lsblk command with and without HD attached.I hope you can help me to get my data back. – user124456 Dec 28 '15 at 16:42
  • @fabby : I followed the commands. At the "mount" command the reply was: " mount : only root can do that". I tried with sudo mount and the reply was " mount : special device sdd3 does not exist" – user124456 Dec 29 '15 at 15:03

To mount your HDD again type:

sudo mkdir /media/data
sudo chown $USER:$USER /media/data
sudo mount /dev/sdd3 /media/data

And you should have everything back in /media/data

  • I might add that I am on live usb. My ubuntu 14.04 installation is not working which was on 20 GB partition.,and I am trying to rescue my data which is on 475 GB partition. As for reinstallation of 14.04 ,I have done it two times but each time it developed problems- may be because of bad sectors on the hard disk. Actually the disk is quite new. Any ideas as to what should I do to avoid bad sectors during reinstallation of 14.04? – user124456 Dec 29 '15 at 15:24
  • @user124456: Fabby's mount command was erroneous (wrong device path). Please try again with my edit! If the mount command results in an error message, please include it in your question. – David Foerster Dec 29 '15 at 15:57
  • @David Foerster : The reply to the command" mount /dev/sdd3 /media/data was as earlier " mount: only root can do that" – user124456 Dec 29 '15 at 16:36
  • Try sudo again! (sorry, edited once more) – Fabby Dec 29 '15 at 16:43
  • @fabby: The reply to sudo command is" mount: wrong fs type, bad option, bad superblock on /dev/sdd3 ...etc. The dmesg |tail output is: exr4_check_descriptors: Block bitmap for group --- not in group...! ext4 group descriptors corrupted. I am afraid to start again the fsck repiars, as they have not helped at all. Btw did you see my comment about being on live usb and how to avoid bad sectors while reinstallation of 14.04 on /dev/sdd ? – user124456 Dec 29 '15 at 16:59
  • yes, I saw that, but that's a totally different question already asked here – Fabby Dec 29 '15 at 22:14
  • @fabby: So, is there any way for me to recover my data other than completely copying on other bigger disk by "dd" and then try these methods again? – user124456 Dec 30 '15 at 16:28
