I would like to retrieve some recent data (a folder) from an ancillary, physical drive I cannot mount. Can anyone recommend a strategy please?

thanks

What filesystem are we talking about here? And what happened that caused the corruption (I.E. hardware or software issue)?

Thanks for your interest.

The file sys was Fat 32 but I fooled around with my hardy disc and now it's

Disk /dev/hdd: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hdd1 2 19457 156280320 f W95 Ext'd (LBA)
root@Knoppix:/ramdisk/home/knoppix#

So why can't you mount the drive ? do you get some specific error ?

LiveCD's of forensics tools..

The short answer is I'm sorry I don't know why I can't mount this drive. I was led to this conclusion at the end of this thread:

http://www.linuxquestions.org/questi...noppix-643536/

could always try to repair the partition table, since that seems to be what it's complaining about,,

can you access the drive through windows ? maybe using something like BartsPE Bootable CD if you don't have windows currently installed.


You can try using the Linux gpart tool
gpart man page

seems the issue is to get the partition table fixed then you should be able to mount and access the drive..

Thanks for your help; I will research your advice.

Thanks for your support; I've made the best of it.

Does that mean you were able to get the partition table repaired ? if so which tool worked for you ? Please share your experience so others may benefit.

Thanks !!

Sorry about my netiquette. I was looking around for a button that said "Solved" to end the thread; I thought that was adequate.

I salvaged much of my data in Win 2k using Data Recovery Wizard. Then ran Partition table Doctor. Now I'm presented me with an empty Drive.

However, I have now replaced that 160Gb with a 250 Gb, which as I understand it, I formated to fat32, then transfered data to it successfully. I am hopping there is a simple command to have it permanently mounted in Ubuntu; although the icon hasn't shown up. Have you any comments please?

to get the drive to mount automatically every time you boot you need to add an entry for the drive and it's mount point to your /etc/fstab file.

something like
and then all your porn.. err I mean data files will be mounted at boot time in the specified location

How-to Mount Windows Partitions

I'm sorry I don't understand?

If I..

nnjond@nnjond-desktop:~$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# -- This file has been automaticly generated by ntfs-config --
#
# <file system> <mount point> <type> <options> <dump> <pass>

There is no opportunity to add another line?

You need to open the /etc/fstab file in a text editor to make additions, using the 'cat' command won't work. Make an entry similar to the one in farslayer's post changing to suit your system:

/dev/sda3 / ext3 defaults 0 0

should work if you have Ubuntu on partition sda3?

Thanks for your help, but I think there is still some misunderstanding:

Places> computer> Filesystem> etc>

takes me to the fstab file which when i add to it looks like:

# /etc/fstab: static file system information.
#
# -- This file has been automaticly generated by ntfs-config --
#
# <file system> <mount point> <type> <options> <dump> <pass>

proc /proc proc defaults 0 0
# Entry for /dev/sda3 :
UUID=95f8506b-2449-4699-910a-b95e06bed52c / ext3 defaults,errors=remount-ro 0 1
# Entry for /dev/sda9 :

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0
/dev/sdb1 /home/nnjond/Desktop vfat auto,umask=0000 0

Then, when I try to save I get a popup:

Could not save the file /etc/fstab.
You do not have the necessary permissions to save the file. Please, check that you typed the location correctly and try again.

You need to be root user to alter a file outside your home directory. Open a terminal window and enter

su
gedit /etc/fstab

and then you can edit it.
