Flying Height

It was revealed to you that floating the read/write head on an air bearing improves the life of the hard drive. The distance between the head and the platter is called the flying height (sometimes called the Float Height). Without getting into a course on physics, the more data squeezed within a given size, the closer the head must be to the platter. If the head hits contamination or the platter, it is called a head crash.

[spacer]The Old Drives Were So Stupid That…

Old hard drives needed software utilities to park the heads. This author learned the hard way about the "dumb nature" of parking utilities. I had made the mistake of calling the utility program more than once a single batch file. The head assembly parked itself up on the spindle on the second park command! I had to use a pliers to get the head assembly back where it belonged :-(
