[SOLVED] External HD won't mount (the laptop battery went off while copying)

Post by doronba » Wed Sep 11, 2019 2:52 am

Hi mates,

[Linux mint 18.3, Transcend external HD]

The problem :
I was copying files from the laptop to the external hd, after some minutes,
while i was in another room the battery of the laptop went off,
I didn't notice that, and now the external HD is recognized by the OS
(i mean that in the windows manager it shows on the side along with the other locations)
but is not not mounted, even after trying to mount it.

Here is the message that i get when trying to connect the HD again :

Error mounting /dev/sdb1 at /media/thedog/Transcend: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sdb1" "/media/thedog/Transcend"' exited with non-zero exit status 13: $MFTMirr does not match $MFT (record 0).
Failed to mount '/dev/sdb1': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.


as far as i know, the HD is ext3, so i don't get what mentioning Windows, or NTFS has to do with it, but i am not an IT expert (in think that i formatted it to ext3 before i started to use it)

Is there a way to save my 'Highly important backup drive' ?
something with Gparted maybe ?

I am horrified to lose all my backup files due to this nonsense (my fault offcourse...)

Thnx guys

Boot to a live media to identify the disk and its partitions using lsblk and sudo blkid, then sudo fsck /dev/<drive><partition#>. That will try to fix damaged blocks on the device and, hopefully, allow you to mount it.

If, for example, you identify the drive and partition as sdb1 then you would type sudo fsck /dev/sdb1

Hey catweazel,

I have added the message that i got when re-connecting the drive,
so would you please read it and tell me whether your answer is still actual before i try anything ?

and mentioning again : I see the external hd in the location column on the side of the windows manager, so do i need to do the three commands that you recommended, or just the last one ?

thnx again

Here are the replies of the commands that you gave me :

-------------------------------------------------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------------------------------------------------

what should i write in the command : sudo fsck /dev/<drive><partition#> ?
i get that the drive is : sdb1, and what about the partition ? should it be fe412bc8-01 ?
i also realize that it might be NTFS formatted (oops), will it work ?

much thnx for your concise answer
