Error: /dev/sda: unrecognised disk label. >>Want to rescue data, but cannot mount it.
Hi, how you doing?
Ok, here is the deal: Got a laptop here from a client, he says hd is kaput!! I boot with Live Ubuntu CD. Run the command parted, which gives: Using /dev/sda. But, when I ask for partitions with command "print", it comes back and says, "Error: /dev/sda: unrecognised disk label" Trying to "check 1" , i.e. check the first partition takes forever..., but finally comes back with the same error, unrecognised disk label..... Gparted scans for devices and cannot locate any. I tried to mount /dev/sda1 on /mnt/windows, nada. It says: "mount: special device /dev/sda1 does not exist." If I can only mount it, then I can run dd for a rawimage, and scalpel or foremost the image and recover the files. Does anyone have suggestions on how to proceed? Sincerely, Hector3rd |
use parted magic/system rescue cd
testdisk |

Every console I go to, it bothers me. Thanks!! Hector3rd |

When I press on proceed, it returns with a "Structure: Ok." I cannot load the partition from backup, there isn't any. I don't want to add a partition, because that will erase data I guess. When I execute "testdisk /list" it gives the same result above, no endmark.... Suggestions?? Thanks. Hector |
First, before you do anything with your HDD, make a backup copy of it. e.g., insert another HDD of greater size and do something like this:
Code:
dd if=/dev/sda of=/path/to/new/backup.img bs=16M Only after having a backup copy you should proceed in trying to rescue data. Quote:

Once you've created the image as suggested by 183 above, is it mountable with QEMU?

Probably, almost 99.99% solved, unless....

I did try to use the "dd" command, but its says no such file or directory. I think the hard disk is gone. Unless there is something else that I can try.... In any case, thank you so much for your help, corrections, and suggestions. As always, thanks a bunch!!! Sincerely, Hector3rd |
