Using a diskeditor

I want to get some experience with using a diskeditor, for example that of Norton Utilities. Is there any workshop or howto or even collection of tips available?
Thanks for answer.

Thankyou mark2150 for your comment.
Of course I know that it is dangerous and could lead to data loss.
But what I wanted to know is: is there any step by step introduction for a first experience available, may be with examples how to handle special tasks or problems. May be this could be got online too. Or how to manage the first steps? Besides knowledge about FAT, are there others absolute conditions?
Thanks.

FAT knowledge *IS* the key to how the disk operates. It's really not that complex. The FAT is a table of the clusters and each cluster's entry tells if it's used, free, bad, etc. Files are chains of clusters. The Directory is a reserved area with a file name, time/date stamp, flags, and pointer to first cluster. Each cluster has pointer to next. That, in a nutshell, is that.

You get into Clynder/head/sectors and such, but overall the disk structure is fairly straight forward. I'ts a real thrill the first time you manually recover an "erased" file by changing the first char of the file name and *pow* the file is back!

The exact "step by step" process depends on what you're trying to learn. I've manually gone into the FAT and marked a cluster BAD and then seen it appear that way on DEFRAG. You can rename files by editing the directory entries and changing the attribute flags - fun stuff. Chase a file across the disk from the directory entry to the tail, one cluster at a time.
