sure, from the backups you did before you installed an OS.

You did do backups, didn't you?

Hi,

Need help on data recovery.

Suddenly my disk device's geometry has been changed to something that
doesnot make any sense. Its a 1.8TB in size and had only one single
partition. Now I can see 3 partitions sde1, sde2 and sde2 of sizes
130M, 140GB and 10GB.

Is there any way to recover data from these newly created disk devices?

Thanks
Paras.

Hi Paras.

AFAIK disks don't get partitioned out of the blue.

They need some sort of intervention to make this happen.

What have you done just before this happened?

Did you try to do an installation of Linux, or something
else?

Also, is it possible for a trojan program to do this to your
HDD?

Kind Regards,

Keith Roberts

Yes true. We are trying to find the out how it happened when nobody
did anything to this server.

No. This is a production server and nobody logs in. Very very restricted.

Are there any know trojan that can change the disk layout?

Can you share the output of ...

fdisk -l /dev/sde

be interesting to see just what these partitions look like in terms of
the disk layout. those sizes sort of correlate with a typical /boot /
and swap partition

Have you checked all your logs? What ports are open?
What CLI tools to format a HDD do you have on the server?

I don't know of any. What applications do you have running
on that server?

You say a production server. What type of server - a web
hosting provider?

What scripting languages do you have running on the server,
if any?

If you give me an email directly, I might be able to do a
remote login for you, and some forensics, as that is one of
my many interests.

Kind Regards,

Keith Roberts

And then there's the other question: who has *access*, physically, to the
server? Staff? Have any staff recently been let go? Cleaning people?
