I think I read somewhere that notebook HDD have special on-board controller memory or a partition where it stores "BAD Block" information. Why some have 8+ megabytes which could be shared memory. When the memory gets filled, it spends most of its time indexing what is good and bad constantly in a multi-threaded OS. Remember the days that you had to do a low-level format using the manufactures recovery tools. Doing a regular format was not good enough. You can check for bad blocks after format.
I tested this theory by imaging a customer's slow HDD and throwing the image on a fresh HDD. Seemed speedier. HP, our service provider, did not like that method under contract since they were always backlogged.
