Hi all,
I wanted to create a live install media from by flash drive using dd.
Following is the command I used,
sudo dd bs=4M if=Fedora-Live-Desktop-x86_64-19-1.iso of=/dev/sdc1
The sad part is /dev/sdc1 happened to be my external hard disk (I wanted
to write the image to my flash disk), this was by mistake.
Now I cannot access files in my external hard disk. My hard disk is 1TB
and had only one partition. With this dd now it has two partitions (sdc1
and sdc2), following are the outputs of trying to mount them,
First, why are you doing _anything_ with a badly out-of-date and
unsupported Fedora 19?
Second, I think you must have written to /dev/sdc and not /dev/sdc1,
since writing to the _partition_ /dev/sdc1 should not have affected the
partition table on /dev/sdc.
Whatever was on the first ~1 GB (997 MB) of your disk is gone forever.
Much of the rest should be recoverable, but that depends on what
filesystem was used. You should start by running testdisk to recover the
original partitioning. You can download SystedRescueCD from
<http://www.system-rescue-cd.org/SystemRescueCd_Homepage>, which
includes testdisk and a host of other useful recovery tools. Hopefully,
testdisk can discover the remains of your original filesystem. Once the
partition table is restored, a filesystem-specific fsck (e.g.,
fsck.ext4) should restore sanity to the filesystem, though much of the
content will likely end up in lost+found. That should include intact
subdirectories with file names, but some content will end up as
anonymous files.
