ok, I have a huge problem..
I use my box for a NAS drive, and now it wont boot, I dont even have the "native" option in the Bootloader..
I have tryed to start up Retoox and Xebian from disk, so I can mount the hda an copy out the data, to reinstall gentoox, but with no luck.

Under Xebian I get an error when I mount the device:
mount: wrong fs type, bad option, bad superblock on /dev/hda2,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Any one that can help me, I really need to get some data out..

your filesystem is corrupt, boot sparkle and see if it will fix the filesystem.


pull the hdd, plug it in your pc and boot with Knoppix ( and fsck it there

I dont think I can use sparkle, I run a native install on my box (Cheesypoofs guide) and I allso dont know how to use Sparkle.

Put the HD in a PC.. I only have a laptop..

Any one else??

I'm submitting this from memory - so it might not be 100%..

Download putty to your laptop ( )
Download Resctoox, and burn the iso ( ... oad&cid=10 )

Boot from the rescue tool cd (resctoox) this gives you a command prompt - it has (limited) utilities available..

The resctoox disk will default to (I believe) set your laptop to the same subnet (ie and run putty. connect to your xbox.
(username, password and IP address will show on your tv)

Now try to run fsck to rescure your data..

If you are unable to boot gentoox (due to corrupt files) you may also mount a USB drive (borrow one from a friend) - and copy the surviving files..

Good luck!

Ok, first off - a word of warning, experimenting with these tools may render the disk unreadable (you might lose all data) - if we had the correct procedure the first time - everything might be saved..

After that word of warning - this is a tip I found (
(your problem may be a damaged super block, so you should use one of the backups - still on the disk)


To figure out where alt super blocks are, do:

mkfs -n /dev/hdc5

DO NOT FORGET -n above!!! -n means "do not really create filesystem, just
show where things will be", and will show you alt superblock list.

then fsck -b <superblock> /dev/hdc5
