I wrote a bit more of Chapter Eleven this morning before leaving for work. Saved. Shut down my WP program. Took the Flash Drive that "Harry Potter and the Unbreakable Bond" is on, and came to work.
Here, I put the drive in my computer, and tried to openthe document, so I can get a few more lines in in my downtime. And the entire 150-plus page document was corrupted.
Fortunately, being the insecure bastard that I am, I had sent two of the crucial scenes to mrsquizzical for her comments, so she returned those to me, and I managed, with a lot of grunting and skull-sweat, to find the unformatted text of the rest in the hash that was my long, long document, so Chapter Eleven could be resurrected.
Thank God for mrsquizzical!
