You are working as a technician at Certkiller .com. Your boss’s computer has been running slowly
the last months and you suspect that the hard drive might be heavily fragmented. Which of the
following utilities should be run to check for fragmented files?
A.
CHKDSK
B.
DEFRAG
C.
FDISK
D.
REGEDIT
Explanation:
FAT: DOS 6.x and Windows 9x-systems come with a defragmentation utility called Defrag. The
DOS version is a limited version of Norton SpeedDisk, and the Windows version is licensed from
Diskeeper.
NTFS: Windows 2000 and newer include a defragmentation tool based on Diskeeper. NT 4 and
below do not have built-in defragmentation utilities. Unfortunately the integrated defragger does
not consolidate free space. Thus a heavily fragmented drive with many small files may still have
no large consecutive free space after defragmentation. So any new large file will instantly be split
into small fragments with immediate impact on performance. This can happen even if the overall
disk usage is less than 60%.
