External HDD in USB-Dockingstation

External HDD in USB-Dockingstation

Postby dirk2869 » 04 Jan 2015, 16:30

Hello together, I need help. My external HDD, 3 months old, wasn't working this morning. So I open the case and put the HDD in a HDD-USB-Dockingstation. I tried "fdisk -l": Device Boot Start End Blocks Id System /dev/sdb1 256 732566271 366283008 83 Linux.

Finally I tried to mount the HDD with: sudo mount /dev/sdb1
mount: can't find /dev/sdb1 in /etc/fstab or /etc/mtab

Any idea, which tool I can try to save my data? Many thanks in advance.

probable there is mistake in syntax of mount command. also directory (where to mount) should be added (here is short tutorial ). if you try sudo fdisk -l (as you did) or sudo blkid -o list you can see all partitions of the system (mounted or not). what is the output? hdd should be mounted automatically. try to insert the plug once more or mount manually.

cheers,

The output of "fdisk -l" is as follows:

dirk2869@polskibox:~$ sudo fdisk -l

Have you any idea, how I can mount the drive /sdb1? I don't know the syntax ...

Thank you.

I try

dirk2869@polskibox:~$ dmesg | tail
[ 7564.325573] sd 9:0:0:0: [sdb] No Caching mode page found
[ 7564.325586] sd 9:0:0:0: [sdb] Assuming drive cache: write through

[ 7610.823046] EXT2-fs (sdb1): error: can't find an ext2 filesystem on dev sdb1.

So I'm afraid that all my data lost ... includes the photos of my father, who died last christmas ...

from the said tutorial (see my previous post)
You need to create a mount point using the mkdir command. This will be the location from which you will access the /dev/sdb1 drive.
$ sudo mkdir /media/newhd
To mount the drive, enter:
$ sudo mount /dev/sdb1 /media/newhd
$ df -H
To view files cd to /media/newhd, enter:
$ cd /media/newhd
$ ls -l

ect.

dirk2869@polskibox:~$ sudo mount /dev/sdb1 /media/newhd
mount: you must specify the filesystem type

I suppose, the HD is broken completely, because dmesg | tail
[ 7564.325573] sd 9:0:0:0: [sdb] No Caching mode page found
[ 7564.325586] sd 9:0:0:0: [sdb] Assuming drive cache: write through

[ 7610.823046] EXT2-fs (sdb1): error: can't find an ext2 filesystem on dev sdb1

did not found any file system ...

Did you think, a data rescue service could help in this case?
