[Q] SD card unexpectedly removed problem! [Jelly Bean 4.2.2

Hey guys a few days a go I just flashed my HTC Desire HD with a new ROM (Jelly Bean 4.2.2). I have a few problems and one of the most anoying one is that every once and a while (once per day) the phone tells me that my SD card has just unexpectedly been removed.

Removing it and inserting it back doesnt fix the problem, I have to reboot it in order to fix the problem for a day.

Any help please...:)
