Knoppix won't detect hardware

[Linden]

Thank you Mr. Schulz for the reply. I am an absolute beginner, but today when I booted Knoppix DVD on my laptop with infected HDD I could normally close, minimize and maximize windows. I did press F2 for help though in the boot prompt but only to snoop around and when I saw option (press I believe F3) Show Desktop I did that.

Still it does not show any disks (partitions) in PCManFM only Knoppix, Desktop and Applications. When I typed suggested code I got this:

knoppix@Microknoppix:~$ fdisk -l /dev/sda
Disk /dev/sda: 80.0 GB, 80026361856 bytes
240 heads, 63 sectors/track, 10337 cylinders, total 156301488 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xb2f2b2f2

   Device Boot    Start                End            Blocks    Id  System
/dev/sda1   *          63   156280319    78140128+   7  HPFS/NTFS/exFAT

How can I access this disk and see and rescue files? Thank you for your time and patience.
