Recovering data from a formatted Linux partition.

Hi.

I appear here today having done something silly. I have accidentally formatted (through a ClarkConnect install process) over a 40GB drive that had many valuable files on it. Can anybody recommend a good tool that will allow me to recover these files - at least some of them. I'm a desperate man and don't care just how much it costs.
It did have FreeBSD on it and I have tried using R-Linux and a tool from stellarinfo.com but both mainly report lost clusters or the new structure of Linux that CC loaded onto it. What are my chances of getting it back? As soon as I realised what I had done, I removed the drive from the system.

Greg

no i have recovered from a formatted linux partition, using data recovery software, just dont add any files on top of it and use a bootable cdrom to run the recovery process and transfer the data to a new drive

I would concur with aot2002 ... data is recoverable ... knoppix is not a recovery tool ... it is just a one cd linux distribution which would let you boot from cd !!!!

exactly knoppix has some basic recovery features but its not a full blown expertise type recovery software, if your data is that important i would buy a linux recovery software and use that to get your files off the drive. Ive also seen where ive formatted a drive more then once and added files and i still can get the unoverwrited data off the drive, ive found its a matter of what software you use which makes a world of a difference too.
Good luck and use google.com to find the tools you need.

gavinw007Commented:
aot2002 my thoughts were helping because I had this same problem and having more than 6yrs in IT and linux...I still couldnt get the data off with even the tools suggested by sunny.

You say you got your data off how about you helping and write a howto telling us all what exact recovey tool you used ???

FYI - I'm not in control of where the points goes, just sharing my past expirences :-/

gavinw007,

the only way you would lose all contents of your partition is if you carry out low level formatting ... that is, you set all disk locations to 0 ... otherwise, all you actually do it clean entries in some tables while files are there on the dis k.. only you can't see/browse them ...
If that is not your primary partition, then doing a cat /dev/hda2 or whatever the device will prove the point ...

the data is recoverable

if your an expert why are you guessing ?

>>soon as the OS formats that's it your data has gone!
what ? have you even unformatted a drive with recovery ?

>>If you want to try use http://www.knoppix.net alot of people use this to recover data but not >>sure how it will fair in you situration.
really like what tools are on this that recover the drive data ? tell me a command to run which performs recovery on knoppix a distro ???????

gavinw007 if you knew of the tools then why did you even mention knoppix
the fact is you in no way helped him isnt that what expert advice does ???????

from :: http://data-recovery-software.net/
"It functions on local and network disks, even if such partitions are formatted, damaged or deleted."

recovering data in such situation is what these softwares are built for ... Who needs a recovery software for a file that I can open with a text editor !!!!
