If your hard drive is trashed, or the file system is seriously damaged it may take quite a while.
A sector is one block on the disk, usually 512 bytes. A cluster is one or more sectors in a contiguous group. The default cluster size for XP on an NTFS system is 4,096 bytes, or 8 sectors. FAT32 varies the cluster size in relation to the drive size.
