Not at all. If you don't post your questions, how are we to know which answersto give you?
As tomlee59 has pointed out, a formal Shut Down is an orderly process, with all the most recent bits dusted, polished and put away properly in order on the shelves. If the system is abruptly shut down without this housekeeping, or if the system even thinks that this has happened, it will whinge at you and set Disk First Aid loose on your drive before startup is allowed to complete.
If real damage has occurred, it is likely to be to the file directory, especially if the drive is already fragmented, and to such things as the boot blocks. Partitions (there are at least five on an HDD with but a single visible data partition, the 'volume' that you see mounted on the desktop) are not likely to be affected, but pointers are. A file utility such as DiskWarrior 2.1.1 is invaluable. The commercial CD has four bootable OSs from 7.6.1 to 9.2.2, and can straighten out HDDs down to System 7.1, but 7.5.3 is a recommended limit. It will also fix boot blocks after it has replaced the file directory, if need be.
And it comes with a companion app. on the CD, PlusOptimizer, which works only on PPC machines, and does a fine job of file defragmentation (as opposed to the directory fragmentation that is attended to by DiskWarrior).
All of this is quite separate from what a disk utility does, which is to look after your drive's logical structures, during setup and repair. DW will not touch a drive unless the partitions are in good order.
