You have a harddrive with 8GB of data stored on it, and the files are fragmented. The average size of a file is 8KB. To defragment the files, the OS copies a file to a clean area of the drive reserved for compacting the drive, then writes the file back to contiguous sectors in the main storage area so there are no fragments in the file. Average seek time and rotational delay for the drive are 5 and 4 milliseconds respectively, with a transfer rate of 8MB/sec. How long does it take to write one file to the compression area and back to the main storage area of the disk?
