Looks like you've already solved it, but return to previous version usually works! c: I use Dropbox: [link] It can recover your files to any time you had saved it, so if you save frequently (like me for every stroke lmao), you can just go back to that version.
Well I was a data recovery specialist for about a year and i have some bad news. More than likely, there won't be any way to recover it. It looks like the machine was in the middle of writing to the file when it crashed. It likely only wrote some of the data and not all of it, resulting in an incomplete file. If it's the only file you have, it is going to be incomplete and very unlikely to be recoverable. Every time I have run into this issue with the sort of data that doesn't have inherit protection against this sort of thing (like databases) the only way to resolve it is to recover from backup. When I do work in Ableton or Inkscape, I save incremental changes to protect against that and mostly so I have something to go back to if i took a track/picture a completely wrong direction.
Ohh I see. Well I'm not too sad about it. :/ Well, I sort of found a solution. I went to a recovery point for my psd file and it actually wasn't very far from when I finished so I guess I can make do with it. ^^ Thank you for the information. I was actually pretty tired of looking for recovery programs.
