Thanks. That seems like an excellent resource (with reasoning, unlike 
what I'm used to :-).

I haven't delved into it, yet, but its description of how the drive 
actually writes data to the disk differs dramatically from what I 
remember described the last time I saw a description of the recovery 
process (it claims the 1 and 0 are merely encoded as magnetic polarity, 
while I remember them being modulated on a sine wave). Which it actually 
is, I'm not sure, but the reasoning your article states for using random 
data (create as low a frequency as possible given the disk's RLE) is 
negated if the data is actually modulated.

Unfortunately, I have lost track of my previous source, but pending 
further analysis, I'm willing to retract my definitive claim that 
needing to use random data is an urban myth.
