And my unit wasn't affected by the click of death apparently.
I still do not really understand why this wasnt more successful (at least by the time CDs existed/were used)
For Iomega, it was because of terrible quality control, leading to fiascos like the Zip drive "click of death" (see https://en.wikipedia.org/wiki/Click_of_death#Iomega_Zip_driv...). A storage vendor whose products develop a reputation for frequent, catastrophic data loss isn't going to stick around long.
For MiniDisc, it was because MD didn't offer a clear leap up from what you could get from compact discs, and because Sony couldn't help but be Sony and go off and develop their own system while everyone else in the industry was using a different one (DCC: https://en.wikipedia.org/wiki/Digital_Compact_Cassette).
