You can use ResEdit to change invisible files to visible files, but ResEdit is a large & powerful program. For something more convenient, I use Change Visibility, a contextual menu utility from Alsoft. Contextual menus pop up when you click on something while holding down the Control key. They offer shortcuts to often-used commands, or to new commands like Change Visibility.
With Change Visibility, when you control-click on a file/folder, a menu will come up that offers (among other things) to make that file/folder invisible. If what you clicked on was a folder/volume (and there are one or more invisible items in it), a second option turns up to "Make Contained Items Visible" with an arrow. Follow the arrow and you get a list of invisible items in that folder/volume. Select any of them and it will be made visible.
You can do this to each volume/partition in turn, making the Desktop.DB & Desktop.DF files visible. Then, move these files from one volume/partition to the trash & reboot. After rebooting, empty the trash.
Repeat with each remaining volume/partition, trashing, rebooting, emptying trash. Don't move the Desktop files from more than one volume/partition to the trash at a time. The Finder renames duplicate files in the trash, & your Mac expects the Desktop files to have the same name until you reboot.
Using Sherlock for this is not a good idea. While Sherlock will find invisible files & can move them to the trash, the trash will not hold invisible files. The Finder will insist on deleting invisible files at once, and you need the Desktop files to remain in the trash until the next reboot.
I don't actually know if Techtool will get the Desktop files on every volume/partition, or just on the boot partition. Sorry - power user. I like to have full control over the process, so I do it myself.
You can get the free Change Visibility
here. Select it from the pop-up Download menu.
If you want ResEdit (also free), you can get it
here.
Hope this covers everything.
