Hi Pan Man. It is quite probable that you won't be able to find Windows 98 drivers for this device. This is quite often the case these days. You will probably find it easier to buy a USP flash drive for transferring files. These are quite rewasonably priced these days, just make sure you chooses one with Windows 98 (or whatever versoin you have) support. If you get a Lexar drive click here, you can download Windows 98 drivers from the Lexar site click here.
