hi, I have installed ubuntu8.04. And I am unable to see/access 5 out of 6 existing partitions which i had before installation.
My issue is quite similar to the people in the thread mentioned below but with the difference that I have installed and now I want to access the drives/partitions.
http://ubuntuforums.org/showthread.php?t=808757&highlight=partitions+ubuntu!
sudo fdisk -l
/dev/sda1 2370 2431 498015 82 Linux swap / Solaris
/dev/sda2 * 1 2369 19028961 83 Linux
/dev/sda3 2432 19458 136755032 42 SFS
Partition table entries are not in disk order
the above is after installation. I have 160GB HDD and I believe that the rest of the 5 partitions(130GB) are intact and just inaccessible.
please help.

Did some Google on partition type 42 SFS. Seems it could be some kind of NTFS partition for windows 2000.
Might try to access it as an NTFS partition.
sudo mkdir /media/windows
sudo mount /dev/sda3 /media/windows/ -t ntfs -o nls=utf8,umask=0222
and use the file browser to navigate to /media/windows to see whats there.

Yes u are right i had NTFS partitions in Vista.
one more thing i repartitioned drives with vista's builtin software some weeks back and repartitioned using "Partition Editor" with live CD to get 3 small chunks of about 1MB,4MB and 8MB.
I thought this information might help.
sudo mount /dev/sda3 /media/windows/ -t ntfs -o nls=utf8,umask=0222
NTFS signature is missing.
Failed to mount '/dev/sda3': Invalid argument
The device '/dev/sda3' 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?

Don't think I'm going to be of any help getting Linux to read your type 42 SFS partition. Haven't been able to find anything short of compiling a kernel with experimental SFS support. Even that thread did not say if it worked or not. Good luck.
42 Linux swap (sharing disk with DRDOS)
42 SFS (Secure Filesystem)SFS is an encrypted filesystem driver for DOS on 386+ PCs, written by Peter Gutmann.
42 Windows 2000 markerIf a partition table entry of type 0x42 is present in the legacy partition table, then W2K ignores the legacy partition table and uses a proprietary partition table and a proprietary partitioning scheme (LDM or DDM). As the Microsoft KnowledgeBase writes: Pure dynamic disks (those not containing any hard-linked partitions) have only a single partition table entry (type 42) to define the entire disk. Dynamic disks store their volume configuration in a database located in a 1-MB private region at the end of each dynamic disk.

Are your partitions Windows Vista software RAID? A software RAID set up through windows will show up as SFS also. Don't expect to be able to access that via Ubuntu.

Thanx for your help. It was informative as well. I'll read a bit more about it.
My problem has been solved. I repartitioned and recovered with loss of 5% data.
