    We have a laptop that will not startup - 2 lights appear when trying but nothing happens. We need to get data back off it.

    I removed harddrive from laptop and connected drive to PC USB with USB to Sata Drive Cable setup. It will not register in Windows Explorer. However, when I go to Disk Management, it seems to see something. It says there is a "Disk 3 Unknown of 465.76 GB" and "Not Initalized". In detail for that drive it says "465.76 GB Unallocated". It also displays a message when I fist enter Disk Management that says "You must Initialize a disk before Logical Disk Manager can access it". It offers initialization in either MBR or GPT partition style. The harddrive is stamped as a HGST of 500 GB capacity.

    Listening closely it seems to be spinning. When it started up I did hear some other sounds but not a lot and it was very soft in all sounds - I had to listen very carefully to hear anything. And have not really listed to a drive before to see what sounds it should make. Also, I have not opened it.

    I am running Windows 7 on the PC and the laptop was running Windows 8.

    I have not initialized it as I assume it will wipe/re-format disk when I am trying to retrieve the data on it. Is it just the case of a drive letter conflict or is the drive just had it?

    Before doing anything, I would boot the system with a linux live usb/dvd. See if linux can "See" your files. If not, then reboot into windows and run data recovery software. I have had good luck with test disk however there are a LOT of data recovery programs. Some are free and some are not free.

    For linux, I would use either linux mint or ubuntu for the first task. Download either one from their respective sites.

    Thanks for reply. I don't know anything about Linux/ubuntu things. Little I know is that they are an alternative OS?
    Do I download one and put onto a flash drive or CD/DVD and let the computer boot from it. Therefore it does not go to windows. Is that correct?
    Therefore the flash drive would need to be in the boot priority? If I use CD/DVD then I need to burn to that with something. Have not burnt anything in years.

    Ok I researched Linux and how to look at it from DVD. Got that working(y)
    On front screen it shows my 2 drives and Seagate external drive and no Hitachi drive. When I select Computer at top of main screenit shows the Hitachi Drive. When I select it says "Unable to mount location - Can't mount file"

    Hummmm:unsure:
