Free Data recovery tool for linux?
my dad formatted a 204GB disk and it's now showing as "Unknown" 199GB partition with 4.7GB extended partition and 4.7GB swap space (witch is how it used to look only with the "Unknown" being replaced with ext4 when looking at it through the built in disk utility), He also stated that it was done with the live install CD. So the data may have been overwritten. but he has told me He cancelled at the beginning of the formatting process so I think he corrupted the partition... or fully formatted it but im not 100% on what he has done. it is not the OS drive only one for storing other data like videos+ images+ installers ect. And also the OS disk is the 32bit version
Can I restore it and recover the data or is there a free tool I can run to recover the old partition and files or are they simply lost?
If I can recover it all from this early stage, can you please walk me through how to go about recovering the data as I am a new user of Linux and its OS (Ubuntu 10.10)
