Pls Help! My computer re-assigned names so the USB port is now called

[HopeHoops]

7. Do you have the same problem with other computers (and the same stick)?

Mine are all Toshiba or PNY, well except for a pocket knife (Swiss - really) that requires its own drivers. I've never had a problem even when crossing operating systems (including Mac and Linux). It SHOULD assign the next available letter after the last internal device. Your D drive is the factory restore partition so it shouldn't even think about installing it there (OS decision, not the stick). Formatting it on another machine is definitely an option. Also, do any OTHER memory sticks do this or is it just the one? The reason I ask is that if you can use it on another machine and not have problems, it is your machine at fault. If another stick works in your machine, that points to the "D drive" stick as the problem. If the "D drive" stick does the same thing with another machine, the stick is dead. Shit happens.

Another thing to try is taking a memory card from a camera and putting it in the SD-MS/Pro-MMC-XD multi-card slot. If you still get the "D drive" thing, then there's definitely something wrong with your machine.
