If you upgrade the firmware on a SCSI device (such as a hard disk, a RAID array controller, or a tape drive) and then restart Windows, the Add New Hardware Wizard may run. The wizard prompts you for the location of drivers to install for the upgraded device.
The Windows Plug and Play manager obtains the firmware revision number from SCSI devices. This revision number then becomes part of the device's Plug and Play ID string. When the upgraded device is enumerated, the new firmware revision number causes a new, unique Plug and Play ID for the device to be generated. Therefore, the device is seen as a new device instead of as the same device that had been enumerated previously.
