Links to storage

Hi, I have a new Archos 80 G9 Turbo with ICS and rooted with 4.0.7... and i have a problem with storage...

I have 8gb internal and 16Gb external by SD card..

But seems to be a symlinks . I tell...

With aplications like File manager tells capacity of sdcard is exactly the same as internal, seems to be linked sdcard to internal storage.

also apps like Titanium Backup can't point to SDCARD for backup when setting destination of backups....

What happen????
