1. Matthew has decided to use the RAID integrated into the SATA controller on his new system. He uses the system for high-end video editing, and would like to improve the performance of the system for this task. What implementation of RAID would you recommend to improve performance?
2. In what situation(s) might it be appropriate to disable the motherboard’s hard drive controllers?
3. Brock, a new tech in your firm, informs you that the PC he’s working on can’t autodetect a hard drive he installed. He thinks the motherboard is broken. What’s the more likely problem here?
4. The second SATA hard drive on your company’s server has just died. You have a replacement drive, but it’s critical that the server remain up and functioning. What, if anything, can you do to resolve this problem and get the second drive replaced?
5. Sean would like to install four additional hard drives in his system. His motherboard has two IDE controllers and two SATA controllers. There is one SATA drive installed, and the optical drive is an IDE device. How would you configure Sean’s system?

3. Amanda argues that a hard drive must be formatted before you can set up the partitions. Samantha says the drive must be partitioned first. Who is correct, and why?
4. Kyle is running out of disk space on his hard drive on a Windows XP Professional system. He has installed and configured a third hard drive in the system to increase the total storage. He is plan- ning on converting his current drive to dynamic storage and extending the storage space to the newly installed drive (also dynamic storage). Pablo argues that the conversion is destructive and that Kyle would not be able to extend the volume anyway. Is Kyle going to be able to make this work?
5. Sean has created a RAID 0 array using three drives on a Windows 7 Professional system. After run- ning the system for a couple of years, he arrived at work one day to find one of the three drives had failed. He thought that if only one drive failed, he would still be able to access his data. What facts about RAID 0 did Sean misunderstand?

Explanation / Answer
1. Matthew has decided to use the RAID integrated into the SATA controller on his new system. He uses the system for high-end video editing, and would like to improve the performance of the system for this task. What implementation of RAID would you recommend to improve performance?
Here in this case we would like to increase te performance, for which we can use the RAID10 implementation. RAID having the combine features of RAID0 and RAID1.
RAID10 provide following features:
1) Increases the performance by striping volume data.
2) Provide disk mirroring features, that helps in case of any disaster.
2. In what situation(s) might it be appropriate to disable the motherboard’s hard drive controllers?
Suppose if your operating system is on your hard disk and if its now working properly then you can disable the hard drive controllers and can load the operating system from cd drive or from usb drive.
1. Name at least two indicators that you should perform maintenance on your hard drive
1. Perform a check for finding the bad sectors in the hard drive.
2. Perfrom a check if disk fragmentation is required or not.
3. Amanda argues that a hard drive must be formatted before you can set up the partitions. Samantha says the drive must be partitioned first. Who is correct, and why?
Hard drive must be formatted first, then we should setup new paritions. If the drive is not formatted and you are trying to partitioned it, then it will cause lots of problems.
