Partitions Currupted .. Urgent Help needed !

[Dark Star]

Hi
I recently installed Ubuntu 8.04 dual boot with Mandriva 2008.1 .. Now Ubuntu has some problem with my system so I formatted the HDD partition of the same using Mandriva inbuilt Disk Manager in Mandriva Control Center.. After I formattedi mounted it at /media/hd1 .. I restated so that everything work fine.. Now it detects only one of the NTFS partition and Filesystem, when I open Mandriva Drive Manager it says the following error..




Now I has some valuable data . how can I recover that ? Any help would be appreciated !

fdisk -l

[root@localhost shashwat]# fdisk -l

well,why not fix the partition table first?
remember,after fixing partn table,you may not be able to boot into Linux.you have to put "fdisk -l" o/p here:
So,do this:
boot a livecd,open a terminal as root:
run :

fdisk /dev/hda

press "x" now.again press "f".type "quit" to exit.now do a "partprobe" in root terminal

now,u seems to have made a raid0 partition?there is no need for raid unless you got identical harddisks

There is nothing wrong with that, but this is larger than 1024,

1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs

[praka123]

well,nothing much.you have to mount the raid partition and see.I dont know much about raid man!.follow the link I gave.

I don't have RAID only 1 HDD> Also that outputwas from Mandriva, boot into Ubuntu Live and when I tried the command I get this error

ubuntu@ubuntu:~$ sudo fdisk /dev/hda

Unable to open /dev/hda
ubuntu@ubuntu:~$

[CadCrazy]

Use
sudo fdisk /dev/sda

[r2d2]

You have a pretty messed up partition table there, hda3 and hda4 looks like primary partitions to me, in that case the extended partition (hda2) should be the last partition. Also hda5 is overlapping with hda2.

[Dark Star]

How do I fix it ! Ok will try sda

[praka123]

well shashwat,you accidentally made a software raid-0 like partition then
partition 70 means " 70 DiskSecure Multi-Boot "
I will recommend you,mount this raid(ntfs?) and backup your data.format it to a regular ext3 partition.

always make partitions manually or using gparted,then show the distro the path to install.
follow this as earlier told:
http://ubuntuforums.org/archive/index.php/t-706335.html

no other solution I can think of

Here is the output with sda in Ubuntu Live Cd

wait,shashwat:
do you have winblows vista installed on 80GB partition?

[Dark Star]

NO I don't have windows

[praka123]

again what is the output of "fdisk -l" ?
do u have 2 harddisks?

also,install this utility called "testdisk" .it will come handy.
dont delete the partition in despair and panic.

I am completely clueless reg something with winblows
still,look what I found:

DISKSECURE — Protects basic disk files from Viruses.
unrated
[added 1998-10-25]
Reviewed by Howard Schwartz (10-06-98)
DISKSECURE: There are three critical files (well, not actually files) at the beginning of your hard disk that perhaps up to 1/3 of the viruses in the wild like to hide in, or like to attack and corrupt:

1. The "Master Boot Record" contains basic software that your computer executes every time you start up and boot your computer. If they hide here, "stealth" and/or "boot sector" viruses can get executed each time you start your computer, and then hide in ram.
2. The "Partition Table" describes how many partitions you have on your disk, what type they are, and where they are.
3. The "File Allocation Table" probably should be called the directory allocation table. It describes where to find all the directories on each partition, and, where to go on the disk, to find out which files are in each directory.

By corrupting or destroying any one of these three items, a virus can make a disk completely unusable. DISKSECURE protects items #1 and #2 from viruses:

• Moving the Partition Table to a secret hiding place and replacing it with its own code.
• Preventing any program from writing data to these parts of the disk.
• Saving a good copy of #1 and #2 offline (e.g., on a floppy), so you can restore them, if the ones on the hard disk are deleted or corrupted.
• Preventing any accidental booting of your computer from a floppy disk. Most viruses still enter a computer from a floppy disk, or other removable media.
• If desired, requiring a password before your computer will boot to and access your hard disk.

DISKSECURE also includes a program that bypasses its defenses if you want a program to be able to access your hard disk's beginning sectors directly. DISKSECURE cannot protect your File Allocation Table in this way because it is constantly being written to and changed as new files are created, old ones deleted, etc. To protect this critical table, use a utility like STF.COM (save the FAT) to back it up each time you start your computer.

So,it will be some small file crapped by winblows? or freedos

not only the partitions, your keyboard has also corrupted.
look at the topic title.
