  • ProRes file reads Zero KB on Disk, but I know it’s there……

    Posted by Jared Rogers on January 17, 2013 at 2:33 am

    Hello,
    Sorry if I picked the wrong forum. I’m looking for help repairing a corrupt file.

    We were shooting ProRes 4444 10 bit onto a PIX 240 to a CF Card and unexpectedly lost power during the take. This was the first clip of the 64GB card, but when we attempted an immediate offload, the disk image read as the following. (“Zero KB on Disk”)

    I really believe it’s still there because it only shows 42.4GB available, and this math works out based on the amount of time we were shooting before power loss.

    Any ideas? I have tried:

    PhotoRec (just recovered files prior to the most recent format)
    Grau GbR (also only saw a zero KB file)

    Thanks!

    Terminal is your friend here.

    sudo ls -lRa /Volumes/THAT_REDACTED_VOLUME

    See what the filesystem thinks is there versus Finder.

    Thanks Tim,

    I should first admit I’m Terminal-ly ignorant 🙂

    The result was hard for me to understand. The only reference to my file came at the end via:

    -rw-rw-rw-@ 1 4294967295 nogroup 0 Jan 16 09:33 XXXX1-15-13_003_001.mov

    The Xs are continuing the redacted text in the file name (for client privacy).

    Does this mean anything?

    Unfortunately, it means that the file did not get written to the filesystem properly, even though the blocks were allocated. You could try a tool like Disk Warrior to reassemble the blocks (they are a linked list, so they connect to one another internally), but I wouldn’t hold out much hope.

    Thanks. Some people I’ve talked to think it may just be a missing footer on the file? This makes sense to me because it was sudden power loss that caused the corruption in the first place.

    Is that something I can replace manually? I have a working file that shares the same specs.

    I’ll also look into File Warrior.

    Nope, not quite that simple – you have to find the interconnected blocks first before you can place an appropriate close onto the file.

    Thanks for the help, Tim. I enlisted Treasured’s software/service (by Aero Quartet) and was able to recover everything.

    For future Pix240 users who find corrupt files like this after a power failure, I recommend the following:

    1.) Create .img file of entire CF card SSD (what have you)
    2.) Use Treasured to run a “Deep Media Scan” of the entire thing.
    3.) Use the handy slices in iPhoto to determine if your clip is there, and follow the steps Treasured recommends.

    Overall cost was $299 which is I think their highest tier of service. Certainly worth it. Their tech support was also very quick when the first “repair kit” had the wrong frame rate output.

    Jared, I just contacted treasured. The empty file was not accepted
    Was that your experience?
    I’m hoping they will contact me with a solution.
    I basically have an identical problem.

    You need to do a “deep media scan” in their software. I remember that was the only way to find the footage.

    They then work up a “repair kit” based on the clips you want to save. Spendy but worth it.

    I too had the exact same problem yesterday. Lost about 65 gigs which was one long clip. First ran Prosoft’s Data Recovery and it was not found although it pulled out older QT’s that since have been erased. Just bought Disk Warrior on Sound Devices suggestion but it will not run on my MAC since it is a Windows formatted SSD drive.

    Very upset with Sound Devices, I just found out last night that they just released 3.5 firmware on the 5th that can help prevent a loss but I they neglected to tell me of the available update!

    Waiting to hear back from Disk Warrior as to a suggestion before I pull out even more cash.

    hello,

    I had quite a similar problem with my atomos ninja 2 record into an Evo SSD.

    I mounted the drive to my Mac and it was empty.

    I used Disk Drill, Ease Data Recovery, Found some files (unfortunately not the one’s I wanted) pro res, used Media Salvage to repair them .

    I used terminal :
