Hi,
here is the scenario:
You Windows 2000 Server computer contains four hard disks of different sizes. Each hard disk is
configured as a basic disk and has a single 5-GB partition. All four disks have the amount of
unpartitioned space shown in the following table:
Disk         Unpartitioned Space
Disk 0              3-GB
Disk 1              4-GB
Disk 2              3-GB
Disk 3              8-GB(i think there is a typo here)
On each hard disk, you create a second partition that uses the remaining unpartitioned space on the
disk. You create an 18-GB stripe volume that includes all four of the new partitions.
Six months later, disk 1 fails. You replace it with a new hard disk, and create the necessary partitions.
As quickly as possible, you need to retrieve the data that was contained on disk 1.
What should you do?

I have to choose one of the following:
1. Delete and re-create the stripe volume. Restore the contents of disk 1 from the most recent tape
backup.
2. Delete and re-create the stripe volume. Restore the first partition on disk 1 and then stripe volume
from a recent tape backup.

the proposed answer was the 2nd one, but i don't quite understand why. here are my questions:
1) if disk1 was physically impaired, would i be able to retrieve the data on it?(i guess the answer is no)
2) if disk1 was not physically impaired and thus failed, what could be the reasons for the failure?
3) why am i supposed to restore the "first partition on disk1" rather than restore the "contents of disk1"?
4) why am i supposed to restore "from a recent tape backup" rather than "from the most recent tape backup"?

Thanks in advance
KEN
