CF Memory- How to identify problems with it!

I am now using CF memory to record all my work i also use tape to back up my recordings as the Sony Z5 with attachment has this facility.

I hear about the nightmare of CF (or any type of )memory going down and then having to rely on the back up tape. As I think we all know transfer of video clips from CF memory is so much quicker and more flexible that using tape this is the way I now work.

Have recently aded to my stock of CF memory, I am really asking is. Is there anyway to test the memory to

1. See that it is fully / partly operational appart from the simple test of trying it out on the camera?

2. Identify any signals when working with the CF memory chips that may indicate that the memory is not operating as 100% and is likely to or about to fail?

3. Is there any way of recovering lost clips off the memory chip?

4. Anyones experience with this potential nightmare senareo!!

I look forward to your comments!!

I used to have CF with my Z7 and S270 camera's and relied on it all the time, in two years I never had a problem but always did three things:

1: Buy decent high speed CF cards, I used the 16gb 133x Transcend ones.
2: Always format the memory card before re-using it.
3: Don't try to put everything on one card and run the tape as a back-up just in case, the 16gb cards were similar size to a 64min tape.

I now use panasonic P2 and have no tape back-up at all but P2 is a more protected system, I still always format the card before re-use and do a safety back up to USB drives.

JG Hi!

Thank you for the information I note you comments though to date I have always just deleted all the clips once I had downloaded theem to the pc and have not reformated the CF memory card. I had read somewhere on DV Doctor (I think) where some person(s) had had trouble once they had formated ther memory cards!! Anyone else aware of this issue??

Thanks again for the info

Also still looking for the first indications of CF failure so that I will know what to look out for if there maybe a problem!!

Deleting will just remove the content but re-formatting will also re-set the directory structure (initialise the directory) and is always the best option when re-using any computer storage device as it re-sets everything and there is no chance of the directory structure being mis-read.

It's a bit like in the old days where if you recorded over a used tape there would be a chance that you would load some of the old material that you don't need, bulk erasing tapes made sure that they were totally blank and ree-formatting card systems does the same so that you are starting with a fresh recording canvas rather than over-writing what was already there with a chance of a directory corruption.

Personally I always re-format my cards before re-use and the only problems I have heard regarding re-formatting were on a bad batch of cards that were faulty anyway and the re-formating highlighted this!

I had problems with the 32GB Transcend 133x cards that, when formatted in the MRC1K, wouldn't then be recognised by either the MRC1K or the computer. So while I continue to use the 32GB cards, I simply delete all the files on the card using the MRC1K before the next shoot.

I always shoot tape at the same time.

It may be that when the MRC1K was designed 32gb cards were not really very available so that 16gb is the max size that can be used.

I use 32gb cards with my P2 but that is a different system as AVC intra is 1gb per min and is verified and protected on the card, It would be scary to be using such large cards with a Z7 and as said the problems was be down to a design mis-match rather than the cards themselves.

No. 32GB is in spec. Other people have not had problems with other makes, it's something about the Transcend 133x 32GBs that the MRC1K doesn't like.

Must be the chipset firmware doesn't conform to their spec then, this sort of thing always happens with computer devices and it is the hardest thing to chase.

Mark Hi!

Thank you or your comments, I thought that I had heard thet there could be problems with reformating which you have now confirmed. I generally use Transcend as the word on the street seems to point one in that direction. Though I also have noted comments about the use and security of using 32Gb CF and the possibility of them going down with a potential huge loss of data. I have one 32 GB CF card which I think is Memorex but as a result of the chatter about 32GB and the potential for loss I now buy / use all 16GB CF cards again using tape as back up!

Thanks again for your comeents

Looks like a good price but consider previous comments on 32 Gb regarding possible issues with re formatting them and also potential loss of a significant amout of data.

This nervousness appears to run though both videographers and several professional photographers that I have discussed this issue with and the photographers tell me that they usually work with memory up to 16 gb but never over that, for the reasons stated above!!

I've got two brand new Transcend 16 GB x133 that will not work with either of my MRC1K s.

They record for about 2 mins then the MRC1K shows error 12.01 (card speed not fast enough) and shuts down. I have tried formatting but no joy.

I think Transcend is the problem.

I was thinking of getting one of these.

It must be the newer transcend cards as I had lots of the 16gb 133x ones for use with my Z7 and S270 and never had any problems.

I suspect they have changed the firmware on the card and the sony unit doesn't like it.

I've no way of telling (or personal experience) but I hear there are fakes out there?

I have heard the same thing, so I did check my serial numbers on the Transcend web site and they came up as genuine.

I have got another x133 16GB Transcend that works fine, so it seems a random problem!

In which case, I would think you've got a good chance of returning them under warranty (unfit for purpose, etc) with your test results and error codes?

I have just purchased two new Transcend 16Gb x 133 CF cards via Amazon from My Memory in Jersey and have used them both without an issue so far, though have not filled either of them to capacity.

Looks like it could be a totally random chip issueissue!! I would have thought that as most appear to operate with the MRC1K then it would appear to be as replacement under the sale of goods act!!

Has anyone attempted to contact Transcend direct to get their take on the issue with their cards and MRC1K???

I've been having a few problems with my HVR-MRC1 and I noticed that sony have a firmware update to version 2 on their website.

http://support.sonybiz.net/knowledgebase/search.aspx#

And also that they only guarantee the following cards for the recorder:

The following CompactFlash cards have been checked for
operation with this unit.
Not all CompactFlash cards are guaranteed to work with
this unit.
Lexar Media, Inc.
Lexar Professional Series
8 GB
Lexar Professional UDMA Series
8 GB
16 GB
SanDisk Corporation
Extreme III Series
8 GB
16 GB
Extreme IV Series
8 GB
16 GB
As of June 2009

None of them are Transcend and I have two 32Gb x133 cards which are having problems with their directory structure and have in fact lost about twenty minutes of material. Fortunately I still have tape back up.

Thanks for the usefull link but as you correctly state nothing on Transcend. I attempted to contact Transcend the other day but having spent time constructing the email it direcred straight to a broken link!!

Nott tooo sure if it was a temporary issue with the website but I have not attempted since!!
