Secondly I'm not sure I buy the USENIX claim that you can limp along less one head. The last failed drive I took apart, was indeed failed on just one head, but it had scraped all the rust off the platter (down to glass! it was really glass!), and the inside of the thing was filled with microscopic grey facepaint. It had slathered the air filtering pillow and coated all kinds of other surfaces. so...I would expect the other recording surfaces were not doing too well either, but I could be wrong. It does match experience, though, of drives going from partly-failed to completely-failed in a day or a week.
Your point here is 100% accurate. Any physical damage inside the drive, even if initially constrained to a single head, quickly becomes a huge problem for everything inside the drive. Once you're looking for physically isolated heads and platters, you might as well just buy multiple smaller drives. -- Eric D.
