 NTFS signature missing hi ,
I was trying with a linux distribution, Fuji Linux on a machine having windows xp only.I though it was a live distribution and tried browing through the cd and unknowing kickstarted an installation. Releasing my folly, I aborted the installation.In the process windows got corrupted.I have not deleted any data further to it.I tried booting through knoppix 5.1 live cd and could see my windows drive on mounting i.e.
mount /dev/hda2 /mnt/windows , though the file names folders appear in cryptic codes
I then tried with the ntfs-3g ( 1.0 stable release with fuse 2.6)
mount -t ntfs-3g /dev/hda2 /mnt/windows
and the outputs is
NTFS signature is missing.
Failed to startup volume: Invalid argument
Failed to mount '/dev/hda2': Invalid argument
The device '/dev/hda2' 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?
and the ouput of fdisk -lu is as
Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders, total 156301488 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
/dev/hda1 63 1044224 522081 82 Linux swap / Solaris
/dev/hda2 * 1044225 156296384 77626080 87 NTFS volume set
Do I stand a chance to get back my windows data, with ntfs-3g ?

NTFS signature missing Hi,
It seems Fuji Linux (Turbolinux?) overwrote your Windows installation. You
may try a Windows recovery software, ntfs-3g can not help.

hmm, the filesystem id 87 isn't normal for a ntfs-partition...
Is that a raidx system? If it is a raid1 there are changes that the other HDD is ok. Else you should backup the partition with a low level program like dd and then try to use chkdsk from a windows-CD.
if it is a raid0 or 5 you should try to assemble the raid again, perhaps LVM from linux or again the repairconsole from a windows-cd helps.

It's a hidden NTFS but that means __nothing__. The filesystem type can be
freely changed, independently of the real file system. What is sure is that
no NTFS on the partition. Probably the installer formatted to ext3 (type
82) then a boot loader or something else changed it to hidden NTFS for some
reason.
I think the 'mount /dev/hda2 /mnt' worked because no filesystem type was
specified and in such cases the kernel autodetects the type, completely
independently what the partition type is in the partition table.

Try a partition/data recovery software. NTFS-3G doesn't include built-in recovery yet.

Can You plz, suggest some free tool/s ?
I'm willing to fix partition..
(hmn i think i have somewhere ultimate boot cd)
Code: ntfsfix /dev/sda1
Mounting volume... Failed to startup volume: Invalid argument.

Attempting to correct errors... FAILED
Failed to startup volume: Invalid argument.
Volume is corrupt. You should run chkdsk. chkdsk... I don't have windows to do that..

---
NTFS-fs error (device sda5): read_ntfs_boot_sector(): Primary boot sector is invalid.
NTFS-fs error (device sda5): read_ntfs_boot_sector(): Mount option errors=recovery not used. Aborting without trying to recover.
NTFS-fs error (device sda5): ntfs_fill_super(): Not an NTFS volume so searched my repos for any kind of tools and found testdisk ,
searched on www about boot sector.. found those:

Similiar mounting problem I have a similar problem in a partition installed for virtual windows.
(1) installed a fedora core in sda5
(2) installed window xp on partition sda2, which is working.
I cannot mount using ntfs-3g, get similar error
When I used fdisk to view the file system. sda2 is 95 vfat, So I changed its fs id to 7. I was still unable to mount after rebooted.
Then, I rebooted my virtual XP, IT STILL WORKS! The FS in partition sda2 must be OK.
In my case, it is not file corruption, but some compatibility issue although corruption is a possibility in other reported cases. I asked NTFS-3G staff to look into possible compatibility issues. Thanks.

If the partition was marked as FAT by Windows then it is FAT.
If Windows shows it as NTFS then either the Linux partition detection code or the block device setup code is not correct, or the NTFS bootsector was corrupted by a virus, partitioner, boot loader, etc. Please see http://www.ntfs-3g.org/support.html#mbr.
This is not an NTFS level issue. Either repair NTFS or set the block device up properly, so it can be accessed by the NTFS-3G driver. NTFS-3G is neither a volume manager, nor a repair/recovery tool ;-)
