The other day I was fooling around with installing a red-hat into my computer (just want to learn more about the OS and might one day free myself from Mr. M) I plugged an old and unused HDD into my computer. I turned off the working HDD with the bios and unplugged it and then manipulate the OS on the unused HDD. After partitioning and unpart. a couple of times (I had some problem with creating the partition which I still don't know how to do so ) I made a fatal mistake. I forget to unplug the working HDD (I had it disable with the bios) and when prompt if I want to redo the partition map, I answer Y (I thought it was referring to the unused HDD). The installation program then tells me about the geometry of the HDD and I recongized I have murdered my working HDD (the working HDD is much larger than the unused HDD). I try to undo but everything was too late. I had some very important stuff on the working HDD since the last backup. I tried using PM, SYSTEM COMMANDER and the like to restore the partition map without success. I know I am just crying over spilt milk now but I would like to see what I can do with it. I have a new system set up on another HDD now and the last working HDD was left alone there waiting for some miracle. Can any of you guys give me a hand?


 
If you remember the partitioning schema, you can try to create it by hand (for example, if you had one big Windows partition, it could be quite easy). If not, well... there are companies that are specialised in this kind of recovery. You can try to contact them. If it was really important data, I also suggest to buy another disk with same parameters and issue 'dd if=/dev/hda of=/dev/hdb' (of old disk is hda and new one is hdb). Such command should do low-level copy of data.
