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?
