hi Greg thanks for the concern . but actually my question was very simple .. it wsnt so complex.
it was just that i was just writing for practice sake a sample block device driver example in LDD there they ahve given all this description abt sector size in ch 16 which confued me totally . so i thought if an of you can if clarify . its not related to any spl block device with me but i dont know how my ques became so complex that i got answers from seems to be third world... so i thought to reframe it for once again ..pl read my ques again ..i am sure any of u can help me ...
