How to recover data from external harddisk...please help...

Asked by SWAGATAK GHOSH

I was trying to install Ubuntu 12.04 in a pen-drive. the .iso was in my external harddisk .

I was using startup disk creator of Kubuntu 11.04.

Now by mistake when the option erase the disk appeared I select my external harddisk.

At once I stopped my task and detach my hard disk from my laptop.

But the external harddisk is not showing now.

In the partition editor it is showing as a unformatted volume.

How to recover my data.

There is some very important documents in my harddisk .

How to recover them ?

Need help...

thanks

Use your backups....

You may find joy with foremost, if the bits that hold the files you want, have been overwritten then the files are GONE

You could also try e2fsck using the -b option for an alternate superblock. The man page (man e2fsck) tells how to get the alternate superblocks if you don't know what they are. This assumes the filesystem is messed up at the front, but maybe some files towards the end have not yet been erased. Never tried this myself.
  Last resort, use dd to pull everything off the drive, use split to break up the huge chunks, use grep to locate chunks of interest (like ones that have your documents), and edit the smaller split file to get the document. You would need the room on some disk for this, and basically, lots of time, since we're talking possibly thousands of split files. (This I have done ; ( but only on an 8G disk ).

Its a simple request. If the files are "important documents" then a backup will have taken place by yourself. Holding important document in one place is ridiculous.

If you'd read on I also suggested a method to possibly recover the data, try re-reading.

thanks
