USB Minidisk/Pen Drive driver for win98

I have lost the installation CD that come along with my USB Minidisk/Pen Drive. This Minidisk can still work in Windows ME/2000/XP since there is no additional driver needed for these environment.
My Question is where can i download the driver if i needed to use this drive for windows 95/98 environment. I have tried to search the web for it but so far i cant get it.

Thanks
