. Operational visuals and sounds of a single 3.5 floppy disk drive, particularly a Panasonic JU-257A135P with its top cover removed. It's being tested by PC-Doctor, a DOS-based diagnostics and information program for back in the day on a Packard Bell Legend 100CD. The media used is a 1.44MB 80-track diskette with some bad tracks around 76 onwards.

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)
