So, here's the thing:

This week a drive came in and this was the customer story:

Computer rebooted and ran chkdsk, upon starting outlook, he realized his .pst file has gone from 8GB to 0KB.
Obviously CHKDSK made this happen, and the file wasn't deleted, but was overwritten IMO.

After imaging the disk I ran a raw recovery, but no .pst files except the 0KB one was found.

Should I just give up or try something else ?

In my experience, one that size will never be recovered. I guess you could look in the FOUND.000 folder at the .CHK files and see if there is an 8GB one, but I seriously doubt you will have luck with this one

why you think it is overwritten, did customer use drive after this happen or create new data on the drive ?

atleast partial recovery should be possible. 8GB is alot sectors.
btw did you try more than 1 software for raw recovery ?

but a partial recovery on a .pst? is that going to be useful? I don't know the format, so maybe a tool can pull out individual .eml files or something, but it is probably going to be one of those jobs...

I've cloned the disk with MRT, then scanned the image with r-studio, gdb, etc. Only found one, the 0KB file, i believe chkdsk did this :s

Good old chkdisk. Who needs those mission critical files anyway, just delete them so the the system has no issues booting Windows. That's all you really want anyway Right?. :lol:

What's making me mad is that the file wasn't even deleted but somehow overwritten to go from 8GB to 0KB :'(

This was such a important client for us. MEH.

Magical update.

After running all some other recovery software I was able to find at raw files some .pst's

They weird thing is that I have 2 pst folders, with 4x 3GB files and 4x 1GB files. (some of the files have recent e-mails, but that's no good enough, im not sure if its the software I'm using or something else, but I'll give it some more shots.)

Does anyone know a good pst viewer /scanner ?

Oh, that's from ZAR!

I've tried it anyways, and after loading the files pops up a error message saying outlook can't open the files.

CHKDSK criminal.

Problem still not solved, I mean, not fully, 10% of the info recovered.

I might outsource this if someone feels like it.
