Error on SDHC Card

On my Transcend 32 GB SDHC Class 6 card, I am getting an error message on one of the files while transcoding . The error message is ""Conversion failed (bad stream or unexpected packet)"

Has anyone else ever seen this error message? I know it isn't good. However, while filming my project, I never received any kind of error message, like check card or anything. It seemed to be filming just fine during the filming process itself. No hint of anything going wrong. Yes, I actually did hit the record button, too.

I can see the file on the card and it is only about 14mb for about 40 minutes worth of filming which is not right either. The file will not transcode and just gives me the above error. I tried to manually open it off of the card on my computer and I get the same error.

When I try to play in my HMC-150 off of the card, it skips right over the file like it isn't there. Of course this file was a very large part of my project. The rest of the files on the card seem to be just fine. I formatted the card before use in my camcorder, however it is the very first project I recorded on the card. The file that is bad is file #22 of 51.

This is my first time using a 32 gb card. I have been successfully using 16 gb class 6 transcends for well over a year with no problems at all.
 
Try the clip restorer from the panny website (where you registered you camera).

Also, was the card formated in camera? It is imperative that cards be formatted in camera.
 
I have had problems with Transcend cards just giving up, and if you look on Amazon, many reviewers have had the same problem. It works for a while, and then all of a sudden, it stops working. I sent mine in for an RMA, and they returned a new one fairly quickly. Once you get your footage off of the card (if you are able to), I would suggest doing some testing with the card to make sure that it doesn't do this again.
 
Basically, my unscientific opinion is that with the the (now) huge demand for SDHC cards, the manufacturers have shifted a lot of production to "other" - cough Taiwan cough - facilities and quality has dropped over all. Even high end Panasonic SDHC cards have had issues.
 
I received an email from Transcend and they said: "It could be the format issue of FAT32, because the SD cards can't be transfer 1 file more than 4G under this format.
Maybe you can modify this problem by formatting the card into NTFS." Has anyone heard of this or reformatted their cards to NTFS?
 
I doubt this is the issue. Besides, yuou can format your card however you like but your Camera will only read fat32 (and fat 16).

Click to expand...

If you mean transcoding like one format to another, I wouldn't suggest doing this on your original SDHC card. Put those files to a HDD pronto.

The less back and forth of data on working 150 cards, the better.
 
fat32 vs NTFS might not be the issue anyways; if the card cant utilize NTFS, it wont record over 4GB in one file. i had a trancend 8GB that took a dump on me a while back, replaced it with a sandisk and havent had a problem since.

i think the issue may be the manufacturer or QC.
 
Thank you everyone, I sent the card back to Amazon. Kind of scarry...
Darn card didn't even give me a hint there was trouble while I was recording.
 
After having the plastic crack on three cheaper SDHC cards and the chip fail in one... I am switching to ATP Promax cards. Them and the Sandisk Extreme's are industrial rated and resin encapsulated.

The ATP's are 20mbps and the sandisk are 30mbps. The ATP's are also about 2/3 the price of the sandisk extremes. SO basically the same price per mbps and both high quality high reliability.
 
I may be a new user of this list but I'm an experienced shooter and PC user.

And I hate to seem critical but I feel I must chime in here. It has been stated authoritively by Panasonic in the manual and in Barry Green's book, etc. over and over:

Thou shalt always format the card in-camera.

Thou shalt not deviate from that commandment.

I must say that this easy to follow rule removes any doubt whatsoever about whther a card can be formatted in such-and-such file format, i.e. Fat 32 or NTFS, etc. Whatever the file format the camera formats the card in, is the format that is the correct format.

Now that that has been definitively answered yet again, I will also say that all small portable storage devices like USB thumbdrives, memory cards, etc. are never formatted in NTFS. People trying to be helpful by speculating or sounding authoritative on advisable solutions to other users' problems without knowing what they are talking about is not helpful and perhaps harmful.

I have a post on my particular problem re my 2 HMC150s is being covered in the technical section under my user name. Not that it really matters to me but is this not really a technical issue rather than a user operational or creative-usage issue?

My two HMC150s are coming back from Panasonic and I will discuss in the technical section. I'd like to hear comments from other users who suspect that their issue is similar to mine, in that it is the camera and not the cards.

Thanks
 
I think I may have figured out the problem....the electric in the auditorium went off during the performance, I was running on my battery power, so I didn't think to much about it at the time. However, I did have a direct audio feed into my camera running from the sound board, so is it possible that I got a surge when power was restored and it corrupted the file? The file that is corrupted on my card is the part of the performance when the auditorium lost power.
