Now, there’s a solution to get it back, thanks to XDA Senior Member [vertigo]. This problem has unfortunately common after installing ROMs on the Sensation XL. As it turns out, it’s due to flashing a ROM that’s not meant for the hboot version of your phone.
The solution is really simple, and can be done multiple ways, all of which are described in detail at the forum thread. So just head over to it and reclaim your lost SD card space the XDA way.
