One way to use contiguous allocation of the disk, Basic Statistics

One way to use contiguous allocation of the disk and not suffer from holes is to compact the disk every time a file is removed. Since all files are contiguous, copying a file requires a seek and rotational delay to read the file, followed by the transfer at full speed. Writing the file back requires the same work. Assuming a seek time of 5 msec, a rotational delay of 4 msec, a transfer rate of 8 MB/sec, and an average file size of 8 KB, (a) how long does it take to read a file into main memory then write it back to the disk at new location? (b) Using these numbers, how long would it take to compact half of a 16-GB disk? (c) Dose compacting the disk ever make any sense?
