Corrupt P2 Footage – Need some help
I have been using the workflow suggested over at HVXUser.
Shoot on location, place P2 Card in Mac Laptop, use disk utility to make a disk image (read only, no compression). Back-up DMG file to external hard drive.
After two days of shooting and 7 P2 transfers one reel will not import into FCP.
This is the first time this has happened and I am going crazy. I have tried everything.
I have tried to import direct (first clip is fine then get nothing but static in the preview window and the rest of the files will not import)
Tried moving the files back to the P2 card and using the Camera function “fix clip” but it is “unable to fix clip”.
Ran disk utility on the disk image – found several errors. Converted the DMG file to read/write and ran disk utility (after fixing the errors, was still not able to bring in footage).
Can pull some of the MFX files off of the Disk image. Is there a way to convert the MFX to Quicktime?
I don’t know what to do as I need this footage (will be almost impossible to re-create).
Also, makes me very nervous going forward. What caused this and how do I avoid this in the future?
I have two laptops – a new macbook pro (last model before intel switch) and an older powerbook (550 mhz) with a brand new fast (7200 RPM) HD. The corrupt disk image is from the older powerbook (I was using the older mac as it had plenty of space on the internal disk)…could this be an issue? I saved the disk image to the internal HD before backing up to external HD. Also, is there an issue with the PCIMCA slot in the older powerbooks?
Just trying to figure it all out.
Please help. Need some sugestions.

As an afterthought,
I am running FCP 5.1.2 on a G5 with all the latest updates from apple.
I really think this is a corruption issue with the disk image…what I need to know is how to fix it.
Is there any way to convert the raw mxf files to quicktime? Anyone use DVRack?

Sounds like the older Powerbook may have a corrupted hard drive. In that case you would need to go to a data recovery place to have them recover the lost data. Then it becomes a cost vs. necessity equation on the footage.

Why make a disc image???
I read that and it seems to like it could
lead to the path you just described….
Copying the files to another folder is
what we do and have had zero problems….
Of course we maintain all computers & HD’s
to prevent such problems…..
After we off-load the P2 cards we
quickly check clips using P2 log…..
Yes we could load up FCP but that takes
longer and I cannot see clips full-screen.
If the clips are good we start shooting again
and Back-up the P2 contents we just duplicated
to an external drive….so we leave the shoot
with two P2 copies…and at the office we
Back-up every P2 card to a DVD-R….. -
this is the workflow suggested over at DVXuser. As I understand it, making a disk image is the safest way to guard against corruption (current problems aside) as it keeps the P2 media in it’s native Fat32 format.
As I do more research and take a closer look at the card in question I wonder if there might have been a problem in the formating of the card.
There are 28 clips on the card.
I can import the first clip but the last frame of the first clip is from previous footage (from another reel shot earlier in the day) and everything after that clip is nothing but static. It is not carryover from a previous reel as the footage in question was one of the 1st shots of the day
I’ve looked at it in P2 Log and the FCP P2 import.
I’m going to try and move the footage to a PC and take a look at it.

Where do you read this on DVXuser? There’s a lot of folks making suggestions over there. Making a disk image of a P2 card is definitely not one of the things I’d recommend. Standard finder copying of the cards contents via dragging and dropping the whole thing is the method I’ve used with 100% success so far.

we are buying and lacie external drive for every project that we are working on. First thing we do is backed it up. I also makes me very nervous to loose material. Even with those back ups i am nervous itis kind of nice to have the tapes as main source. i guess we will have to get used to it. Hopefully we won’t hear too many horror stories about loosing footage.

I hate to burst your bubble but Lacie drives are the worst!
I started out with some Lacies and lost mucho work from
things crapping out on the drives.
Return it ASAP and get some G-raids….
And I would back-up P2 cards to a DVD-R as well…..
I never trust one-copy on a hard drive…. -

I have to agree about Lacie drives, they have caused me more head aches that I care to talk about! Had a 200G and a 250G die within a year and a half! I bought some Glyph HD’s………..so far so good!!
