I own a Netgear Readynas with 2 500G drives installed (mirrored RAID-setup).
Because I'm customizing it, which is really a lot of work for me, I made a backup with DD using following command:
Code:
dd if=/dev/hdc1 of='readynasOS.iso'
. hdc1 is a 2GB partition which holds the Operating System.
Now, I've bricked my NAS, and have done a factory reset (It just formats the NAS syncs the drives and leaves me with a empty, clean device). Next, I hooked up the drive (the first physical drive of the NAS device as that one holds the OS) to my Windows XP SP3 computer. The image of the Readynas is also on my XP desktop on a seperate partition. Then, I booted into Knoppix using the Live CD.
It appears Knoppix names everything sdax (x being a number) but I suppose that is not a problem. The image (readynasOS.iso) is in the root of the sda4 partition. The disk whose partition needs to be restored is the hdc1 (Knoppix named it sdb1)partition.
My first mount attempt got this error:
Code:
mount: can't find /dev/sbd1/ in /etc/fstab or /etc/mtab
I alterered fstab and mtab (see extra info for their content) and then I got this error:
Code:
oot@Knoppix:/ramdisk/home/knoppix# mount /dev/sdb1/
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
And I did do a dmesg | tail getting following info:
Code:
lo: Disabled Privacy Extensions

And as you might guess I'm stuck now. Does anyone know how to get this mounted thanks,
