I posted this question to share the answer: if your pen drive was USB2, and you incorrectly disconnected it (withouth using the taskbar icon), you may have damaged it. Many of those damaged pen drives still works ok if they are connected with USB 1 interface. try disabling USB2 in your bios, start your operative system, and if still not detected your pen drive, try making OS detect new hardware or hardware changes (to crange usb2 drivers to usb1 drivers). This trick rescue many electrically broken pendrives.

There are jumpers on the drives that differentiate the master from the slave. If the jumpers aren't set correctly, the BIOS will not recognize them. In addition, some IDE ribbon cables are also labled Drive 0 (or Master) and Drive 1 (or Slave). If the jumpers are set correct, but the drives are plugged into the ribbon cable incorrectly, the computer will not recognize the drives.
Of course I recognize this fact. Did you mean to ask HOW you recognize it?
