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

/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

Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x4ff14ff0

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
cfdisk /dev/sdb
Code:

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.
