I’ve gotten the same error for all Scapple documents also =/ , and gotten this error for both apps on two machines (2009 iMac 27, 2012 MBP Retina) running DP7.
Both machines backup with Time Machine, but another common denominator was my use of the new Bittorrent Sync, which works like DropBox but without the cloud aspect. I read that it paused when apps were open, so I didn’t hesitate to open Scrivener/Scapple files from the synched directory. I also just uninstalled XtraFinder that I used for cut/paste, but I don’t think it’s involved.
However, a Scapple document stored and opened previously in a DropBox folder just came up with a zero-length window. “The XML data could not be read from disk.” Both apps had been used before DP7 with no problems. However I can’t duplicate the error totally on demand; there’s a short delay where I can keep re-opening the project then … no more.
The package folder hierarchy is the same between working and corrupted projects ( Name.scrivx, Files, (Name.scrivx), Quicklook, Settings). Note that some of my projects’ names have a space in the beginning (to move them to the top of a folder), but only the first Name.scrivx has the space. Also, not all projects have two .scrivx within them, but this doesn’t seem pertinent to my errors…
What I’m observing is that documents are diminishing in size within the .scriv file after opening. I have one working document that I have not touched at all — duplicated it, opened it successfully, closed it, then it won’t open.
Specifically, the first (not second) .scrivx diminishes drastically: 75Kb to 8Kb for example. The corrupted one even gets a new creation date of right now, not when I made the file.
In the Quicklook folder, the Preview.html and Thumnail.jpg get smaller to reflect the icon change.
In Settings, the ui.plist went from 77KB to 3KB, again with a new creation date.
One project has gone from 1.1 MB to 508 KB.
I don’t see any general errors in Console or a Scrivener-specific log.
So it’s isolated to the XML files, which seem to be wiped out? The only other Mavericks/DP7 problem is with my Money.app database going empty. Didn’t happen with DP6.
On the plus side!!! I have gotten a corrupted project to re-open by copying the untouched-project’s 1st Name.scrivx and Settings folders. The zero-length error still pops up, but it opens. If I don’t copy the Settings folder then it opens with all folders in the binder closed.
Here’s an image of the project folder and the main .scrivx files.
On the plus-plus side, thank the world for the backups folder. It looks like my projects are safe. But there are no backups of .scaps, are there? Here’s praying for Time Machine.
EDIT: Scapple files restored and locked from changes. (I don’t know how else to keep this corruption from happening. )
I last edited a Scapple file successfully on September 3rd. On the 4th I updated the MacBook from DP6 to DP7 and installed Mavericks over my ML install up to DP7 on the iMac.
