SDHC "check Card" Error Message Urgent help !

That' s an interesting point about DSLRs. Photographers have faced this issue a lot longer than us.

I think redundancy is a must in the next HMC150. I don't mind doubling my card expense. The footage is too precious.
 
Denwa:

I don't think you said what brand your card was. Can you let us know?

Did you turn your camera off immediately after stopping recording. Maybe it was still writing to the card? I have done this without losing anything, just asking.

It's not that I think the failures are certainly tied to a card brand, size or type, but it's good info to know what cards are failing.

Has anyone had a Sandisk brand card failure yet?

I shoot weddings with my cameras and this all makes me very nervous. Hopefully, it is a very few having issues. But even a few is too much if it's a non-repeatable event.

Currently shooting Transcend, Ritek & Sandisk. Going only with Sandisk in the future.

Although this may not be any Panasonic issue, I think they need to analyze the failed cards and get to the bottom of this. User error is one thing, equipment failure is another. Or if there is an intrinsic problem with SDHC, lets do something about it.
 
@Jeff- I made the same conclusion. My Transcends are for emergencies. I only use Sandisk Extreme II. (The Extreme III are overkill for event video).

A-DATA Turbo series 32GB SDHC

No, I had hit stop at least a minute before turning off the camera.

A-DATA is going to attempt data recovery from the card and will replace the card.
Now I know this isn't a Sandisk III, but even the panny cards (about as expensive as a sandisk III) have had problems.

Trancends have been recommended...until lately as I have heard of problems with some of those now. Possibly a new factory in Taiwan or something. Patriots; the same thing.

Now if it is due to mass production = less quality in the builds, is it the MC ship burning out due to continuous (long clips) use/voltage intolerance ? Or is it the connections to the circuit board? Or is it the MC getting scrambled for some reason? or ???

It would be interesting to know if this is more prevalent a problem for video vs still pics and what is actually the cause of the problems.
 
Hi everyone,

I would like to know 3 things about these cards that fail.

1. What is the manufacturer , the size of the card and the Class # of the card?
2. What is your workflow to offload and get ready to reuse the card?
3. Approximately how many times have you used the card?
4. What were you recording at the time of the error message?

I am trying to see if there is some commonality in the incidents. I do know that all SD memory is not equal. Some have bad sectors, and just make minimum spec for Class 4. Any how if you want to help out in the research, I would be grateful.

Best,

Jan

You prefer PM's or just post in here Jan?
 
I can't report on what has failed.. but in 2 years of use, my transcend 8 and 16 gig cards have worked flawlessly in the SD9 and the 150. My panasonic SD cards have worked the same way for a year. So far no problems with cards.
 
1. Panasonic 16GB Class 6
2. I drag and drop the PRIVATE folder onto my hard drive to back it up. I format it in-camera before each wedding.
3. Brand new card. After fiddling with the protect switch it ended up working for two weddings, then stopped working. Panasonic replaced it and even checked the new card before mailing it.
4. I put the card in the camcorder in order to format it and I got the dreaded 'Check Card' message.

I suggest also posting the part number. usually on the back of the card. Maybe it will shine some light. For example. I have heard good things about trensends, until recenlty when (from what I read) they opened a new factory in Taiwan. Some of there taiwan made chips were having problems (at least according to what I have read online).
Not sure, but hopefully part numbers are different.

Anyways,

My Dead Card:

1) A-DATA Turbo Series
32 GB Class 6.
Part# G32GNMB970393
Purchased around November 4th
Completely Dead, not just a scrambled file system

2) I format in camera before use of the card. I dump footage to computer and reformat card in Camera.

3) The card had been used 5 times for roughly 6 - 18gb of multiple clips per use. And a half dozen times for just a few short clips for experimenting with the camera settings.

4) I was recording a football game and stopped recording after each play. Stopped recording then about a minute later I turned off the camera (at half time). At start of second half I turned on the camera and immediately saw the "Check Card" error.

Sorry! I have been using mostly Transcend, some Panasonic, and one PQI card for over a year with no problems at all. I have had TWO cards fail - both SanDisk!

i think its amazing how each of us are having problem with different brand of card.
is there a software to check on the performance of the card before usage?
 
Before critical usage, I test each card by loading it up with data a few times (just random files from the computer). No card I've ever tested successfully this way has later failed. Clearly not a guarantee, but it seems to work.

Various discussions have pointed to the write-protect switch as the culprit in many cases. I exercise these a bit, and firmly switch them to the non-protected position before each recording...
 
Coming from a engineering point of view - card that have higher quality check like scandisk and panasonic might have less problem. Of course there are also mid range and more mass produce.

Beside checking recording on the camera, you can tell the lifespan and condition of the card. doing a record check for this moment, you record the card with power on. Does not mean the next moment, you on the camera, your card will be function properly. Honestly, how many times do we have the time to check if the card is recording properly by doing a few test on the spot. Ideally, there should be a software to check the card before usage. at least we know that its still in good working condition.
 
Integral Ultima Pro 16GB class 6 card. Used in a brand new hmc151. New card, recorded on several times over 3 days, never removed from camera. Failed; says "check card". Camera will not format and AVCCAM restorer will not work (PC reader will not recognise card).
 
I have 4 Panasonic 16GB class 6, 2 Panasonic 16GB class 10 and 1 Panasonic 32 GB class 10.

I only had one small problem with a Panasonic 16GB. My recording stopped about 1 sec. after having pressed record and the file was corrupted. I had to press record again and everything went fine since.

I have recorded a few times with this card before. I used it maybe 10 times since this problem.

Your card is corrupted. i think this is the situation that we all want to avoid. it can happen even if you test the card before usage.
