Dear Mrs. Plunar
A suggestion for a safer method of creating files.
1) Name each blank document: When you open a new document, get in the habit of immediately giving it a name and saving it to a sensible location on your hard drive (I like creating folders on my hard drive with client names and job descriptions, for example). Then, as you work you just have to hit Command-S periodically to save your work, it becomes second nature.
2) Never work on a file in a remote location: Whether it is a USB flash disk, floppy/zip drive, or an online volume such as iDisk, or a network attached volume, don't use it for primary storage of the file you are working on.
Always save the file on your local hard disk, work on it there, and then copy the file to the remote location in the Finder when you are completed. If you are doing more work on an existing document, save a copy to your hard drive first and work on your local copy, then move it back.
3) Save incremental versions: This is an excellent opportunity to also implement a versioning system where you save As... successive updates with a version number or a date in the filename. This allows you to go back to an earlier version if the current one gets messed.
One good reason why to only work on local hard drive files, is that remote storage, virtual storage (disk images) and removeable storage devices can go away unpredictably, which can have serious consequences in document corruption.
Thanks,
