Question 1161659: Suppose the hard disk above has 1024 cylinders, 8 tracks per cylinder, 32 sectors per track and 1024 Bytes per sector. The maximum seek time is 450 msec, the time to move between adjacent cylinders is 10 msec, the rotation time is 14. If the entire disk was full of data stored consecutively, how much time would it take to read the entire disk if the read/write head is already positioned on the first sector of the first track of the first cylinder of the disk?

You can put this solution on YOUR website! .
This problem/text is full of technical details, whose meaning is unclear to "general public" - these details are known
and make sense for specialists in hard disks mechanics ONLY.
So, EITHER this problem is targeted to the technical specialists in the area, and then this forum is not an appropriate
place for it ---- OR all technical details should be clarified along with a detailed guidance/description attached
and explaining on how this mechanism works.
In particular, this fragment "the rotation time is 14." produces very strong impression to me due to its absolute nonsense.
If you ask me what exactly is nonsense in this fragment, I will answer you:
- The dot after the number "14".
I hope that you, the reader, do understand the meaning of my notes.
Have a nice day (!)
