Consider the following scenario. You connect a PCMCIA storage device to a Windows Vista-based computer. For example, the device may be a PCMCIA card reader. Next, you put the computer to sleep, disconnect the device from the computer, and then wake the computer from sleep. In this scenario, you may experience one of the following problems:

• The PCMCIA storage device is still listed in Windows Explorer, even though the device was disconnected.
• When you reconnect the PCMCIA storage device, the device does not work.
• The computer stops responding (hangs).
• After the computer has been running for a while, you receive a Stop error message that resembles the following:
  

  STOP 0×0000009F (parameter1, parameter2, parameter3, parameter4)
  DRIVER_POWER_STATE_FAILURE
