Twice now in two days my internal & external SD's become unavailable. The first time I noticed when I got a text message and it wasn't my custom tone. The second time today I went into Astro to look at some files and no directories would load. Resetting the phone fixes the problem and everything else works fine. Anyone know why this is happening? Did I good search on this but haven't seen anyone have the same problem. SGS i9000 unlocked. I'm on JM1 rooted with OCLF.
