like it says what data recovery software do you use?
i have a HDD from a freeclick 1tb extarnal drive. i poped it open ,because i have not been able to find my cords for it for the past year. its being a pain, because it uses software to access the drive and its not formatted like windows drives so i thought i would ask you guys/girls. )
Depends.
Usually if it's just corrupt partition table, cgsecurity's testdisc will grab it. For deleted files, some ddrescue (or was it DD_rescue or gddrescue? I keep forgetting) can work well.
Apple's HFSplus stuff is a lot harder but is possible to mount and read files from in linux.
Live Linux distros I use are either slitaz or crunchbang, usually run in RAM.

If the drive was encrypted, there are ways of recovering data from it that vary from being easy to impossible, depending. What "software" do you use to access it? I need some more info to be able to really help.
