Photoshop crash = loose layers i had created

Question

photoshop crashes  = I loose layers i had created (yes, i had saved the psd -- several times-- while i was working)
it appears the crash blows out the saved work
is this known?
is there any way to recover the layers if this happens?

Answer 1

Like Pierre suggests, I have a scheme of using Save, Save_As and Save_As_a_Copy, with regularity. Each has similarities, but also differences. Save is for what you have in your Image now, but overwrites all previous Saves. Save_As is slightly different, in that it does NOT overwrite, if you follow Pierre's rec. to increment, and it keeps that "new" Image Open in PS, so you can continue working on it, and your last Save is safe. Save_As_a_Copy is something that I do at the end of the day, as it does NOT keep that incremented Image Open. This then becomes a separate backup. I use that feature more often with my Premiere Project, than my PS Images.
I also do not Flatten, until the very end of the workflow, and ONLY after I have done a Save_As, or Save_As_a_Copy, to keep my Layers intact, somewhere. Then, and only then, will I Flatten, usually doing a Save_As to the format/specs. that the client needs for me to deliver.
Good luck,
