Re: [ubuntu-uk] Please help.I've lost my partitions

2010-01-26 Thread javadayaz
Just to let you know, that i used Testdisk last night. It worked a treat. I
am in the process of retrieving my data. I have managed to get back at least
65%. Have almost filled up a 240gb on a 300gb disk.

I am most grateful to all of you for your help.

2010/1/25 javadayaz javada...@gmail.com

 will testdisk let me do a search file type at a time? so for example i can
 search for mp.3 files in one search, .doc in the next and so on?

 2010/1/25 Rob Beard r...@esdelle.co.uk

 Quoting javadayaz javada...@gmail.com:

  The original hard drive was 400gb and the new one im installing is the
  300gb...i could try and use that!

 Ahh, problem is, it won't fit on the 300GB drive.  dd will copy
 everything on the drive regardless of if there is data there or not.

 You'd need a 400GB or larger hard drive, ideally possibly larger
 unless it's an identical model drive (I've found in the past that some
 drives from different manufacturers despite being listed as the same
 size, they can be slightly different in capacity).

 If you're really stuck you could possibly use gzip to create a backup
 image of the drive to your 300GB drive...

 dd if=/dev/sda | gzip -9  /media/harddrive/backup.img.gz

 where /media/harddrive is the location of where the 300GB drive is
 mounted, if you mount it from Gnome then it's likely to be mounted on
 a folder in /media

 To be honest though if you can afford it, you could well be worth
 getting another drive to back it up on to just in case.

  and thank you for responding.
 
 Boot from a livecd, DON'T BOOT FROM THE HD UNTIL YOU HAVE DONE THIS
 RECOVERY STUFF!

 Have a look at a program called testdisk (sudo apt-get install testdisk)
 , it runs from a terminal (sudo testdisk) but does have a terminal based
 gui to lead you through recovering stuff. I've used it several times to
 recover lost partitions. It can take a while to run though.

 But seriously, everytime you try and boot from the HDD and it fails you
 risk damaging what remains of the data. So boot from a CD to do this.

 Hope that helps.

It won't be mounted correctly, since it's lost the details of the
partition table (i.e. the list of partitions on the drive).

Do what Matthew Daubney suggested - use a liveCD and install TestDisk.
IIRC you can point TestDisk just at the drive (/dev/sda), it doesn't
need to be mounted. Trying to mount it might cause further damage.

you might find IRC is a better way to discuss this and get it sorted out
more interactively than on a mailing list
on a different computer, or on a live CD on the dead one, go to this web
page http://webchat.freenode.net/?channels=ubuntu-uk and tell us about

You do not want to mount it!

The output of your fdisk -l command shows that there are no partitions 
on /dev/sda so you can't mount it anyway.

I'm not sure of the applications you'll need, but follow the advice of 
previous posters:

Boot from a LIVE CD and then install the system tools you need to try 
and repair the disk. You *might* just need to re-create the partition 
table for that drive.

My first suggestion would be to download the System Rescue CD and try 
some of the tools on that: http://www.sysresccd.org/Main_Page

(I tend to keep a recent copy of this tool lying around at all times).

Have a look at this: http://www.cgsecurity.org/wiki/TestDisk

It's the TestDisk site.  I'm unable to provide much more at the moment  
as I'm at work using restricted internet access.  There is a guide on  
there for recovering deleted NTFS partitions, not exactly what you  
need, but it's a start.

IIRC you should find testdisk on the Ubuntu Live CD.

I'd also recommend as suggested elsewhere, go into the Ubuntu-UK IRC  
chat room and ask for advice in there, someone might be able to talk  
you through recovering your partition using testdisk on there (it's  
been a good couple of years since I used it so my memory is very hazy).

I'd strongly recommend getting another drive of the same size or
larger and dd'ing the broken drive.  Then you can work on a copy if
the drive without touching the original data.

Working with a borked drive is dangerous in that in trying to recover
the data, it's very easy to make matters worse

Get another drive before proceeding and install in the machine.then

sudo dd if=/dev/hda of=/dev/hdb bs=4k conv=noerror,sync

(where hda in the example is the original broken disk and hdb is the
new blank disk).  You can then work with a copy of the disk without
worries...

Good luck

Yes the hard drive is still assigned to sda, but by what you have

Is there any output you've missed off the output of fdisk?

If you run sudo fdisk -l do you get any similar output listing

What happens when you try and boot the machine, are you able to boot 
anything from the hard drive?

Also is there any chance you have another hard drive kicking around

  does this mean that the above hard drive is still assigned the sda label?
 
 Yes the hard drive is still assigned to sda, but by what you have
 posted, it looks like there aren't any partitions on the drive.

 Is there any output you've missed off the output of fdisk?

 Running...

 sudo fdisk -l

 on my laptop gives me this...

 Disk /dev/sda: 250.1 GB, 250059350016 bytes
 255 heads, 63 sectors/track, 30401 cylinders
 Units = cylinders of 16065 * 512 = 8225280 bytes

 /dev/sda22433   30337   224146912+  83  Linux
 /dev/sda3   30338   30401  514080   82  Linux swap /
 Solaris

 If you run sudo fdisk -l do you get any similar output listing
 /dev/sda1, and possibly /dev/sda2 and /dev/sda5?

 What happens when you try and boot the machine, are you able to boot
 anything from the hard drive?

 Also is there any chance you have another hard drive kicking around
 (such as an external drive for instance) which bigger than the drive
 you're having problems with?

Boot from a livecd, DON'T BOOT FROM THE HD UNTIL YOU HAVE DONE THIS 
RECOVERY STUFF!

Have a look at a program called testdisk (sudo apt-get install testdisk) 
, it runs from a terminal (sudo testdisk) but does have a terminal based 
gui to lead you through recovering stuff. I've used it several times to 
recover lost partitions. It can take a while to run though.

But seriously, everytime you try and boot from the HDD and it fails you 
risk damaging what remains of the data. So boot from a CD to do this.

Hope that helps.
