My laptop suddendly quit working, simply boots no longer, giving an error stating that it cannot find a disk where to boot from. I suspect that the harddrive is corrupted or broken.
Well, I booted the computer with my SystemRescueCd USB installation in order to take a looksy. I cannot get any sight of the harddrive, below are the commands I've executed and their output

[======DISK======] [=============NAME==============] [====SIZE====] [MAJ] [MIN] [sda ] [DataTraveler 2.0 ] [ 489.00 MB] [ 8] [ 0] [=====DEVICE=====] [==FILESYS==] [======LABEL======] [====SIZE====] [MAJ] [MIN] [loop0 ] [squashfs ] [<unknown> ] [ 259.99 MB] [ 7] [ 0] [sda1 ] [vfat ] [SYSLINUX ] [ 488.23 MB] [ 8] [ 1]
Here the DataTraveler 2.0 is my bootable USB stick with the SystemRescueCd on it.
Disk /dev/sda: 512 MB, 512753664 bytes 56 heads, 32 sectors/track, 558 cylinders, total 1001472 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: 0x0365986f Device Boot Start End Blocks Id System /dev/sda1 * 32 999935 499952 b W95 FAT32
I also skimmed through dmesg and tried to grep it for "hda", but found no indication of the hardrive.
lshw gives me some output for SATA controller and such, but can't really say what to look for in here.
Is this a lost cause and the hardrive is simply busted? Or is there something else I can do to discover the drive for mounting it and saving the data?
Another boot with SystemRescueCd and
fdisk -l now shows the drive as
Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders, total 488397168 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: 0x3421b7ec Device Boot Start End Blocks Id System /dev/sda1 2048 27265023 13631488 27 Hidden NTFS WinRE /dev/sda2 * 27265024 27469823 102400 7 HPFS/NTFS/exFAT /dev/sda3 27469824 488394751 230462464 7 HPFS/NTFS/exFAT

Note: The USB drive mentioned above is now mapped as /dev/sdb
Attempts to mount the device give me the following output
root@sysresccd /root % mount -r /dev/sda1 /mnt/windows mount: special device /dev/sda1 does not exist
Same error also for sda2 and sda3 when attempted to mount.
lshw now shows the device details.
One more thing I just realised. This time I booted SystemRescueCd so that it's fully loaded to memory. Maybe this has something to do with how the other drive is shown.
