with USB recovery media cannot get to c: drive with diskpart

I am using an ISO USB recovery for Windows7.
In the CLI, my command line prompt shows: X:\windows\system32>
I get error message when entering C: The request could not be performed because of in I/O device error.
I do see the disk (disk 0 and it will give me the size of the drive)when I enter list disk after typing diskpart at the X:\windows\system32> prompt.

I performed bootrec /fixmbr and bootrec /fixboot operations before this to rebuild the master booth records.

I am trying to repair the bcd with attrib bcd –s –h –r, but I believe I would first have to be able to get into the C:\ first.

Any recommendations or solutions?

After running diskpart and the list vol there appears to be a
c: drive with 19Gb and a
d: drive with 649 Gb
Both are healthy, but format is RAW.
What would the best procedure (if any)be to get these drives in the correct format without losing the data on them? I have a feeling she unplugged a removable drive without first using the safely remove drive step.

Ztruker,
Thank you for your help so far. I left for vacation, so I haven't worked on the laptop since. I am going to attempt to recover the 2 drives from RAW back to NTFS. Just want you to know that your help is appreciated so far.
