Hi John,
You can try searching the internet--I found a few by searching "cassette to CD":

If Scan disk will not run in Windows 98 safe mode, you may have a hardware conflict--try removing devices such as the sound card, NIC, extra devices, start in safe mode, then run scan disk. If you can afford a third party scanner such as Symantec's Windoctor, you could use that.
How's the air up there? Mutants for Nukes!!
