Apple System Profiler 2.1.1: USB Removable Media Appears Incorrectly

I have an iMac that shipped with Mac OS 8.5. I have connected a third-party SuperDisk drive to iMac's USB port. When I open Apple System Profiler, and open the "Devices and Volumes" tab, I can see the SuperDisk, but it is under a header called "Internal RAM." Why is this?
The SuperDisk you have inserted is not an internal RAM disk. This behavior is an anomaly under Apple System Profiler 2.1.1. It may also occur with other third-party removable-media solutions connected to iMac via the USB port. This anomaly has been corrected in Apple System Profiler 2.1.2, which is available for download from Apple Software Updates sites.
