I am a big fool. But i believe this could be the event for every serious linux administrator. I Accidentally formatted my hard drive from LVM to Ext3. I tried some of the recovery tools. I can see around 13 GB recovery from 500+ GB contents. I learnt from this mistake. But data is really important for me. Even what recovery software is offering me to recover has no correct file names. They are random file names. So obviously all source code has no use to recover in that state. Because there is no link suppose to be there in this random state.
I can see all data is there. mkfs.ext3 re-write the blocks. I don't know if there is any hope i could recover everything in the same stage. But whatever recovered should be in exact format.
Please help me if you can suggest me any open/commercial solution to recover whatever possible.
I learnt lesson from this mistake.
