Help Galaxy S2 : no more access to internal storage

[batz09]

Hi,

on my GalaxyS2 I'm no more able to access my personal data/folders located on /mnt/sdcard/
I only see 2 (empty) folders "external_sd" and "usbStorage".
But I'm quite sure my personal data is still there, but it doesn't show up because access rights are gone ?

- All the apps I previously installed (partially on internal storage) are still working
- When I take a picture with the camera : no picture is stored on the device !
- When I check the storage parameters, I get 12 Gb USB storage free / 12 Gb total
- Access from my PC : same result, only "external_sd" and "usbStorage" are visible

My phone is rooted
Anyone able to help ? I would really appreciate, thanks in advance
