I used it once to copy files from my PC to my laptop and it worked fine. I tried doing it again right after and my laptop stopped detecting it. My PC still reads it fine.
If it helps the USB port still works for my portable floppy drive and Xbox controller. And I bought the USB drive because my laptop CD drive had suddenly (randomly) stopped working (still works for DVDs). If anyone has any advice for that too feel free to pitch in.
edit: oh, and my laptop dosen't have an internet connection.
