Please If you do not know the answer do not solve only part of it

Question.I Suppose a disk drive has the following characteristics 4 surfaces 2048 tracks per surface 256 sectors per track 512 bytes/sector .Track-to-track seek time of 1.5 milliseconds Rotational speed of 7200 RPM. c) if the head is mounted on track-0 and an order came for the drive to start recording from track 100, sector-0, then how long does it take to start recording? d) if you have a file of 20MB (MB 1024 1024 Bytes) and want to record it starting from sector-0 track-200. How long does it take for recording (including all times), if the head was initially positioned at track-50? Question.2 Next will be specifications of HDD disk drive and SSD disk drive. Calculate how much it costs to store 10 TB of data for 7 years? Assume that both the HDD and SSD are active 25% of the time and that the cost of electricity is $0.125 per kilowatt hour. 800GB SSD Drive cost $1000. The 800GB server-grade HDDs cost $400. Facility cost also applies. Price Cost/Month/GB $1000 Active watts | Idle Watts 10 0.25 0.015 None 15 HDD DRIVE SSD DRIVE N $400
