HD Showing up 0.0 GB size/capacity

Its an Acer Aspire One 722 Netbook and WD Scorpion Blue 320GB HDD and Im trying to install Windows 7 Home Premium. Whenever I boot in BIOS it recognizes my hard drive. THe problem is when I get to the setup screen and it asks me to choose a storage and my HDD is showing up unallocated. Is there a way to check if my HDD is dead or can it be formatted?

  1. You can install to an unallocated space, Windows 7 will partition and format the space.

    It wont let me. My HDD Just shows up as 0.0 GB with only one partition. The setup is asking to choose a storage device and wont let me install Windows 7 on this hard drive. The laptop crashed previously and now I'm trying to do a clean install and it wont let me use my HDD. I tried removing it and connecting it back. Still nothing.

    Is there a way to format in cmd?

    Assuming that your hard drive works, you can use a command prompt with:
    diskpart
    list disk
    select disk n (the disk that you want to fix)
    clean

    If diskpart won't allow you to perform operations on the drive you may have to use the inactive command before clean.

    OK i had to boot from a USB drive and I can get to the cmd by going to the "repair your computer" section of the setup wizard.

    how do i knwo which command lines to use?

    Thanks again for the response.
  5. Start with these:

    diskpart
    list disk
    select disk n (the disk that you want to fix)
    clean

    HERE is a site that has all the diskpart syntax, but I would start with that simple set of commands from a command prompt.
