1) Question: What is the drive seek time of the Macintosh Classic?
Answer: The seek time for all Apple 1/3-height drives is 25 milliseconds.
2) Question: What is the initial interleaving?
Answer: The interleaving is based on how fast the circuits can keep up with the data flow. The Classic has an interleave ratio 1:1.
3) Question: Can dealers install third-party drives without voiding the computer's warranty?
Answer: As long as you make no modifications to the Classic (the dealer must use Apple's mounting scheme, not drill new holes, and the like) then yes.
4) Question: Who makes the drives, and does Apple have multiple sources?
Answer: Apple cannot comment on drive vendors; vendors may change from model to model. The guarantee is, however, that any hard drive will have an average access time of 25 milliseconds.
