I'm a newbie to Linux. but I'm a confident Windows user. I have a damaged hard drive with many bad sectors from my parents windows computer, attached via Sata cable to a Virtual Ubuntu (on my Windows Desktop). I want to use ddrescue (GNU) to create a Disk Image. Can someone tell me what to type into the ubuntu Terminal to achieve the following: invoke ddrescue. skip over bad sectors (to avoid wasting hours and hours of time). create a Log (map file) to enable ddrescue to resume itself if the computer hangs or crashes or restarts. avoid imaging the Windows System Files (MBR) partition (as I dont intend to restore windows.. I only want to recover data and not waste time imaging windows OS files). Extra Questions (to add to the above): Am I supposed to Un-Mount the damaged drive before invoking ddrescue ? how can I do this ? Will I be able to run ddrescue a 2nd time more thoroughly to try to image the sectors that were skipped on the 1st image and then MERGE these 2 images to create a more complete image ? Can I control how often the mapfile saves itself ? Can I control how many attempts it makes to read a sector before skipping to the next sector ? Software/hardware info: I'm running Ubuntu GNOME from a USB Memory Stick (virtual machine, and with Persistence on my Windows 7 Desktop computer). Faulty Hard drive is connected to the motherboard with Sata Cable. PS: Am I correct in doing this with Virtual Ubuntu ? or would I be better off installing ubuntu as a dual boot on my windows desktop ? I am under the impression that the virtual machine Persistence setting will allow for the ddrescue mapfile to resume itself if the computer crashes or restarts.
