ext3 data recovery after formatting

[dexter.deepak]

i was about to install suse and remove windows from my dualboot ubuntu+windows system. while partitioning i gave the option for formatting windows, and had only set the mount point of my 2 ubuntu partitions.
unluckily, after install, both my ubuntu (ext3)partitions are also formatted !! i have lost BULK of data of which i have no backup...and cant expect to get anywhere.
now what i want is a hope to get atleast some of my data back...is there any chance..or a tool ??
can undelete tools also recover data from formatted partitions ?

Check out Test Disk. Do not use that hard drive, unless absolutely necessary. If you do, you will lose more data.
