&gt; the problem of people not being able to get their disks out of their machines if the OS for some reason refused to release it<p>My first time on a Mac, about 1990, I felt pretty confident having plenty of early PC experience. A graphic designer I shared a house with had left me alone with (and permission to use) her Mac.<p>I quickly discerned there was no software of interest actually installed, but found a floppy that looked something like a game. It wasn&#x27;t, and I went to hit the ... wait, there&#x27;s no eject button?<p>After a fruitless few minutes during which I failed to notice the eject key on the keyboard (of all places!) I eventually opted for tweezers, and gently teased the floppy out of the drive.<p>Imagine my surprise when I restarted the Mac to find it was unable to start, having apparently completely forgotten about it&#x27;s own HD! The thing had to go back for servicing before it would even boot properly, iirc.<p>My reputation as the house&#x27;s resident computer expert was severely impacted, needless to say.
