[CentOS] data recovery

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.
