Problems with raid and hard drives.
 
Hi,

Unfortunate my nas died some time ago. Therefore I tried to restore the Date on it. It had 2x466 gb sata hard drives. I think that just the controlling chip is broken. Therefore I tried to mount it to my pc, where i tried to store the data to my external 931gb hard drive. unfortunately i ran into a bunch of problems. Currently I am using Knoppix, for rescuing my date.

My first problem is:
If I enter fdisk -l it only displays my ide harddrive, which i am using for my main operating system and one of the sata hard drives. It even does not display the external usb hard drive:

Code:
root@Microknoppix:/home/knoppix# fdisk -l

Disk /dev/hda: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xc44ec44e

  Device Boot      Start        End      Blocks  Id  System
/dev/hda1  *          1        6527    52428096    7  HPFS/NTFS
/dev/hda2            6528      24320  142922272+  f  W95 Ext'd (LBA)
/dev/hda5            6528      24320  142922241    7  HPFS/NTFS

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x4ff14ff0

  Device Boot      Start        End      Blocks  Id  System
Why isn't the sda and sdc displayed? What does it mean?

My second Problem isthat that under "my documents" it displays 3 hard drives and the external hard drive.
I am allowed to access the external drive but not the three other ones: sda7, sda8, sda9.
it displays:

which should give you all information about my pc, you need.
What is the meaning of this and how can i acces my sata hard drive?

My third problem is:
if i try to mount my working hard drive i get:
Code:
root@Microknoppix:/home/knoppix# mount /dev/hda1 /mnt/hda1 -t ntfs
NTFS signature is missing.
Failed to mount '/dev/hda1': Invalid Argument.
The device '/dev/hda1' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?
Why does that happen and what can i do to mount other hard drive?

And finally my fourth problem:
If i enter cfdisk /dev/sda i get the following message:
Code:
                      FATAL ERROR: Cannot read disk drive
                          Press any key to exit cfdisk

I hope this does not mean that my data on my sata drives is lost. If so is there a possibility to restore it?
Currently I am using KNOPPIX_V6.0.1CD-2009-02-08-DE.

I am thankful for any help.

Your syntax for mounting is wrong. http://ss64.com/bash/mount.html
mount -t ntfs source destination
Some older systems may not support ntfs mounting. You may need to get a separate program installed to do the mounting, I forget the name of it but I had to use it a few weeks back for a windows partition on linux.

You should be able to access your NTFS partitions in read-only mode, as Knoppix usually mounts them read-only by default.

It doesn't look like the NAS stored the data on your two 466 GB hard drives in a recognizable format...

You might need to repair/replace the NAS with an exact match, make- and model-wise, in order to access the data.
Worst case scenario: when your NAS "died", as you put it, it might have corrupted the drives installed in the device.

Hi

I still wonder why does knoppix display
Code:
root@Microknoppix:/home/knoppix# mount -t ntfs /dev/hda1 /mnt/hda1
NTFS signature is missing.
Failed to mount '/dev/hda1': Invalid Argument.
The device '/dev/hda1' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?
After trying to update my system with http://www.linux-ntfs.org/doku.php?id=ntfs-3g i got the following error(after using "api-get update"):
Code:
root@Microknoppix:/home/knoppix# apt-get install kernel-headers-`uname -r` fuse-source module-assistant
Reading Packet list... Done
Establishing connection tree     
Read Status-Information... Done
E: Couldn't find Paket kernel-headers-2.6.28.4

I wonder, because Linux is able to find the array information(I do not try to offend you with this):

Code:
root@Microknoppix:/home/knoppix# mdadm --examine --scan
ARRAY /dev/md0 level=linear num-devices=2 UUID=163218f3:299b9ccc:3c666c38:60539313
Also I remember that a command(sorry i forgot which one) I used returned that the sda hard drive is formated in ext3.

I still hope that it is possible to mount the raid with knoppix, because it is not possible to get an identical nas.
