Nope, because the platters contain servo tracks. Those servo tracks is what tells the controller where the head is at any point in time as it floats on the platter. I assume when they low level them, they use a special machine that plugs into the headstack/spindle and lays out all the tracks first using fixed positioning information and actuator drive signal, then they put the controller board on the drive. It is a servo, and all servos require a reference and/or feedback.
Once you disturb the servo tracks, the head will get confused where its at and it will slam and jump all over the place. worse than the click of death. Stepper motor drives dont have this issue because well, its angular position is constant. 1 step is going to move a fixed degree angle, never more or less.
Same thing with a CD player. There is a positioning track on the disc, so the laser knows how to focus and track itself along the disk, and knows exactly where it is at all times. Without this, the laser would move and bob everywhere eventually giving up. (happens when lasers start to get weak, they cant see this track as easily). Same with CD-Rs, there is still a spiral track recorded even though it isnt "burned" with information, and the laser records the information into the track as well as tracking "to" it. otherwise the laser would never know where it is, and it couldnt focus or track. a servo track has to be present regardless.
