memory stick problems

Hey im new to this thread and am unsure whether i posted this in the rite place but anyway i have a problem with my Psp mem stick. Its a sony pro duo high speed 2 gig and when i put on some music it just crashed my psp. I rebooted it and reformmated my mem stick coz it might of been corrupt data or something a rather. Neway same thing happened my psp crashed and i rebooted again but this time the psp couldnt read the thing. The lights that shows whether its reading is flashing but it says no memory stick is inserted. It wont formatt on the psp and i connected it to the pc and tried reformatting but it says there no drive in there. ANy help i heard this also happens to digital cameras, is there any way i can reformatt the thing or fix it up some how. Cheers PapaK

 

same here! it blinks but "there is no memory stick inserted" msg received!

no memory stick issue as i've tried other MS as well on this PSP (no read!!same blinking!!) & verified the MS on another PSP and PC as well(it works perfectly!)

it's my PSP ...is there any way to fix this without sending it to Sony?
