ok

#

{Delayed Write Failed} Windows was unable to save all the data for the file P:$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere.

#

oh no, this is a pretty serious problem

quick panther Apr 1, 2025, 9:34 AM

#

you would think.. yet all data it there

#

windows not being able to write to MFT seems horrifying. i have no idea what couldve possible happened behind the scenes for evrything to magically come back

#

have you checked your drive's health recently?

quick panther Apr 1, 2025, 9:36 AM

#

indeed, oh, but the one thing lost was the new project i created. it is like it reverted to a snapshot the moment before i deleted Library. everything after that (an entire Unity project created and running) gone.

#

chkdsking now

#

#

so after deleting library, i assume the changes were queued up in memory but were never committed to disk for whatever reason

quick panther Apr 1, 2025, 9:39 AM

#

yep. would be the first time my cat-like reflexes screwed up my computer :/
I had initiall hit the regular Delete. it was prepping to send to recycle bin. I cancelled that, and did Shift-Delete. i think your theory is just about right on

#

oh that makes more sense then. i guess windows reverted to the last stable state on its own after detecting the writing failure, but i had no idea windows could do that on its own...

quick panther Apr 1, 2025, 9:42 AM

#

i didn't either.. but, been a couple decades since i worked as a tech, so, much has changed

obsidian pecan Apr 1, 2025, 9:43 AM

#

ohhhhhh actually, it never actually rolled anything back, it just never saved in the first place because of what i assume to be a NTFS hiccup

#

not writing to MFT could feasibly cause something like this

quick panther Apr 1, 2025, 9:44 AM

#

yep, seems that way. odd though it was able to accommodate something as large and numerous in files as a Unity project, and then, just dump it :/

obsidian pecan Apr 1, 2025, 9:45 AM

#

yeah i would never expect ~~unity ~~ windows to act like its commiting all of these changes to disk without actually doing anything

quick panther Apr 1, 2025, 9:45 AM

#

i don't feel like examining the swap file, but it may have held it here, or possible it was just in in RAM, like you said. 64 GB

#

i am just going to thank my lucky stars that i did not lose all the work i thought i did. 🙂
