Chapter 4: Completing Advanced Disk Operations62
Changing a Drive Letter
The Change Drive Letter operation lets you change the drive letter assigned to any
partition visible to and supported by Windows NT/2000/XP. If you are running Windows
9x or Windows Me, this operation is not available.
1 Select the partition whose drive letter you want to change.
You cannot use this operation to change the drive letter for your CD drive.
IMPORTANT! You should not change the drive letter originally assigned to the
Windows NT/2000/XP boot partition (the partition where Windows is
installed). Changing the drive letter to anything but its original
designation will cause severe boot problems and may cause your
computer to be unbootable.
2 Click Partition ➤ Advanced ➤ Change Drive Letter.
The Change Drive Letter dialog appears.
3 In the New drive letter box, type or select the drive letter you want to assign to the
partition.
4 Click OK.

The Bad Sector Retest operation lets you check sectors on FAT or FAT32 partitions that
have been marked bad and recover sectors that are usable.
The FAT and FAT32 file systems allocate disk space for file storage in units called
clusters, which are composed of a fixed number of sectors. Because the FAT or FAT32
file system tracks bad sectors at the cluster level, it marks an entire cluster bad even
