I have a 32gb Kingston usb stick(flash disk). I do not know why, but this stick does not seem to be 'compatible' with my mbp, osx-lion. When I want to eject it, several times I have to 'force-eject'. Not always though. Other times I try to empty the trash, with usb stick connected to mac, which means that the trash can has also usb stick deleted items, and my mbp crashes(halted - I have to restart mbp). I tried to format it, I used disk utility also, I formated in pc-windows as well, I tried so many different things. No convenient result. It seems that something is wrong and I do not know what it might be. I use other usb sticks with no problem. I use this stick in windows without problem. I have 'blueharvest' pane installed in my system. I cannot believe that this usb stick is faulty, because is Kingston, and I use so many Kingstons without problems. After all, if there was a problem with the stick, wouldn't it happen in windows machines too? But I use it in windows without problems. But something bad happen in this strange relation between my mac and this stick. Can you help me solve the problem?
