SanDisk Ultra II Class 4 Emergency Plan
on May 16, 2009 at 4:22:58 pm

Interesting...

...a week after seeing the SanDisk Class 4 failure thread...I had one 16GB go unrestorable. second use/second format

More than half full... I thought from the existing thread that things were pretty much hopeless. The EX software said the media needed to be restored in the camcorder, the camcorder reported that it was unrestorable. The EX software wouldn't transfer any of it, and even Windows Explorer wouldn't move the data off the card.

But...I could see the damn QT files and even though QT wouldn't open them (ANY of them, not just the last one), on a long shot, I decided to open Premiere Pro and see if the editor would load the EX1 QT essence files...

...it imported and played all but the last clip.

So...next problem. saving it out.

I thought I'd try to be clever and bring all the shots onto the timeline and trim the project (in order to write all the clips in their native format to another location...). Failed...unknown error.

So...I took the timeline with all the clips and tried to export the whole works to an H264 file through the Adobe Media Encoder...somewhere about 3/4 of the way through I had another unknown error.

Now I'm putting each clip on the timeline separately and processing each out of PPro. I'm messing around with a couple different codec options, and I'm still not convinced that I can't do some sort of Project trim if I can disable the XML read/transfer process and restrict the trim to using the file essence...

For those of us in this predicament, this might at least offer a last-ditch option for those of you with critical media on one of these SDHC cards...

I'll post any other particulars I uncover...

you might try this
shoot 10 sec on a SxS card and put it in you sony browser
drill down the BPAV file> CLPR till you get to the Quicktime file and delete it. then go to the Sandisk and copy all the Quicktime files you have and paste them onto the SxS card in the browser. when you refreash the browser they might open.
or not, i have never had this problem so i don't know

Once you have the MP4 files, you just need the SONY Clip Browser to re-package them in a new BPVA.

Tell me more Rafael... I have the essence files, but I can only move them off the media in Windows Explorer through copy/paste...

PPro seems to import everything on the media, but will only play back everything but the last four clips...they create an importer error.

I'd rather not transcode them if I don't have to, but I'm not aware of how to use the clip browser to reconstruct the infrastructure. The clip browser keeps telling me I need to put the media back in the camera to restore...and as I said earlier, that doesn't work.

Thanks

Hi Tim,
You just need to import the MP4 to the SONY Clip Browser.
The application build a BPAV with those files.
You can upload the new BPVA to a SxS card and use the SONY Transfer as usual.
Even more easy, put the BPVA inside a folder in your finder and point the SONY Transfer to that folder.
I was able to recover everything from inside two SDHC cards. Except the two corrupted MP4 that made the cards fail.
Tim, I don't remember how i did it but was really easy. I will try to do it again and i post you.

Hi!

I recovered my 21 (2GB) lost files with Data Recovery. But they all were filed as .mov not .MP4. I tried to simply rename them to MP4 but the Clip Browser couldn´t import any of them.

Any suggestions?

Cheers

Lars

If they work as MOVs than be happy they work. FCP handles EX .mov. On Windows you'd need the CalibratedSoftware plugin but you can test with their free trial.

Well, I can´t do anything with them. Apparently its not a .mov either. FCP can´t import it, Clip browser can´t. I tried Treasured and the preview showed that its actually the footage I did lose. So I need a converter I guess to fix them...
(Edit)
I´ve just found out that my mp4s probably lacks "headers" which has turned them into .mov. So i guess there must be some software that can add a proper header to make them readble for Clip browser

Hi lars,
Try "RescuePRO". Is the SanDisks freebee application. It works better in cards than DataRescue, File Salvage or any other (I've tried all of them).
If you don't get that working you will need to contact "Treasured" if you want to recover the files.

Nope, Rescue PRO didn´t work - but Card Recovery did and Treasured completed the task.
It wasn´t any important material but for a reasonable 216 USD I could have 1 hour of filming restored without any losses. Good to know the day when the shit really hits the fan!

So I did use Kensington adapter and Sandisk 16 GB class 4 - was I just unlucky or should I use another brand or just another classification?

Hi Lars,
Is really amazing how it works Treasured. Expensive, but in cases, the only solution.
About the SDHC cards, I'm not updated, but sure don't use the Class 4.
These are the one that let me down. Since then I stopped working with SDCH.
Sure Craig will inform you better.

Hi Tim,
I tried again and it works.
I don't know how it looks the SONY Clip Browser in a PC.
In a Mac looks like that:



The only thing I've done is create a new folder. I've call it Recover.
Then IMPORT the clips to that folder.
When you import the MP4, the Clip Browser creates a BPAV inside that folder.
You can add new MP4 and the BPVA is updated with each import.
After that I've open the SONY Transfer tool and "Add Source".
The "Recover" folder shows like any SxS card.
Just select and convert.
Rafael

Hmmm...

'Import' works with the non-corrupt MP4 essence files. Nice.

The advantage over messing around with Premiere Pro is of course no transcoding is necessary.

I had four clips that were corrupt and simply lost...in this case, not a crippling loss because it was short b-roll shots on the card. If it had been a lengthy interview, I'd have been hosed.

Thanks Rafael.

(I'm considering attempting a re-format in the computer to see if the card can be salvaged for non-critical use...seems like a useful exercise)

Hi Tim,
You can do the formating in your computer, then when you put the card in the camera will ask you to Restore it.
I give up using the Class 4. Too risky. I will try to get some Transcend. Craig haven't had a single problem with them.
Is a pity that Christmas still so far away. I have ready the present for some of my friends.
Best,
rafael

Yes...having one fail so quickly is a cautionary note for sure.

These cards were tested by the MxM folks as well...it's pretty tough to see the future.

Although Panasonic probably has semi independent divisions but I wonder if the idea behind "Class 10" is that just as SDHC covers SxS (except for overcrank) Panasonic needed something to cover P2. I wonder if Class 10 can handle the 100mbps AVC Intra. If so, it should overcrank nicely depending on how hobbled Sony's USB interface truly is or maybe the Class 10 card is not compatible at all.

I tried the PANASONIC Class 6 few moths ago.
Don't work. They behave exactly like the SanDisk Class 4.
They worked some time 20 minutes, some times 2 minutes before asking you RESTORE.
May be the Class 10..

Hi Tim - I had a similar situation last June with exactly the same card. Card not readable on the EX3. However, I was able to rescue pretty much all the footage as I found I could mount the card on the Mac using a USB card reader. However there was a corrupt clip (the one which I was recording when I got the error message) which caused the spipnning beach ball whenever I tried to access it. Anyway, after trying a few things I found that XDCAM Transfer got me out of jail (Clip Browser didn't work). If you can get yours to mount, this might work for you:

In XDCAM Transfer, navigate through the BPAV folders to the mp4 files (and once it sees these), your clips should show up. It worked for me, Also I found that a corrupted clip would play until two thirds way through then gave the spinning beach ball. On restarting XDCAM Transfer and positioning an OUT marker a few secs before this corrupt bit, I was able to salvage the 'good' part of the corrupted clip.

Hope this helps - after this experience I decided to only use SxS cards.

Martin
