. Operational visuals and sounds of a single 5.25 floppy disk drive, particularly a TEAC FD-55GFR 7149-U5 (that I just acquired and repaired a simple write-protect fault on). It's being tested by PC-Doctor, a DOS-based diagnostics and information program for back in the day on a Packard Bell Platinum 2220. The media used is a 360K 40-track diskette.

Tests performed are:
Hi-Low Seek (Head is moved from 1st track to last track repeatedly)
Funnel Seek (Head is moved from outermost tracks to innermost and then back out again)
Track-to-Track Seek (Head is moved up once each track from first to last)
Random Seek (Head is moved to a randomly designated track)
Linear Verify (Same as "Track-to-Track" Seek but disk sectors are read/checked)
Random Verify (Same as "Random Seek" but disk sectors are read/checked)
