Ext4 data partition not accessible anymore

[danifv]

Hi everyone! I've been using these forums for some time, and finally I decided to register today. :)

I had an old installation of Ubuntu 9.04 (Jaunty Jackalope) where I first tested the ext4 filesystem, creating a ~300 GB partition for data.

At that time I was dual-booting with Windows XP, and while using a partition manager in this OS, I got a warning that there were some mistakes in the table of partitions and the application would try to fix them, I accepted and screwed up access to all the files in the data ext4 partition.

I remember with some file managers I was able to see the folders in the root of this partition, but once I entered those folders, they appeared empty.

Could you recommend me any file explorer or tool in order to recover the files in that partition?

I would really appreciate any help, thanks in advance. :D

just so quickly I can think of software called testdisk.

It is available for win and linux and it may or may not restore all this partition.
Note that many partition manger apps still do not cope with ext4, therefore I was trying to awoid it if possible so far.
