HDD GURU FORUMS

My UPS has died and the PC turned off while I was working in Photoshop. After I booted back in, the PSD file is corrupt (the last 70% of the file data is now just zeros). Any way to recover the data with some advanced tool?

may be you should look for *.tmp file in the same folder and renaming it to *.psd will help, not sure but worth to try.

PS doesn't store tmp unfortunately.

Then maybe last resort was pagefile assuming you could "freeze" the HDD (no, not putting it with the ice cream etc.) and maybe even not . Otherwise, a lot of job to do again :S

that sods law that as your hard drive was writing and it went down

not much you can do unless you might try system restore and hope windows backed this file up

windows restore only modify system files, it has nothing to do with other files you created or deleted

if the file system restore possible the temp file would had been restore allso

Try this.

determine the locations where the file was being written.

this can be, your personal folder i.e. documents/photoshop/
and/or photoshop working folder , possibly ps folder at programs files.


On those directories, run some DEEP recovery software scan, dont scan just for *.psd but for any file.

This could* show some iteration of your file, at some point. try looking for the file sizes in the results, and recover those files that near your *.psd file size or are close to narrow results.

By this same process, you could try to recover the virtual memory that photoshop was using at the time the system went down.

So DONT run photoshop again, and run file recovery on the drive and hopefully place where photoshop stores its virtual memory.

Once you recover the virtual memory file ( bigger than 250MB file possibly), i have no idea what you can do. Maybe search the binary for a pattern taken form your partial save (and hex digit sequence...), and try to find and extract the file in the virtual cache.. but that must be harder than voodoo.

good luck.
