The GCC-5241P should get any available drivers from Windows Update's Plug and Play option, if you have Windows Update set to retrieve device drivers. The only drivers supplied with the external drive were for Window 98 SE.
Looking at the online pictures of the GCC-5241P, the drive used a serial to USB adapter. If you have connected the drive to your computer, go to the Device Manager. (Right click on the Start button and look for the appropriate line or left click and type the phrase). Look in the appropriate sections (Ports, Human Interface Devices and Universal Serial Bus) for a driver with an exclamation point in a yellow triangle. Double click on this item and check the various tabs to get the details that Windows used to identify the device. This might be a Prolific USB to UART/Serial/Printer device. If so, you need to know which chip and the version. A common Prolific serial to USB is the PL2303. The drivers for this are available here:

I hope this helps.

(I have several devices around that used the Prolific chipset. Unfortunately the oldest one, which was Windows 2000 and XP compatible at release, is not supported under Windows 10. Some other units still work.)
