Cfv cfv-39 formating the cf-card

Now , as the delivery of my CFV-39 is coming nearer , I would very much like to know , if there are differences in formating the CF card in a CFV/CFVII and the CF39II/CFV-39 .
I do not mean the handling of the keys .
Can a CF card , formatted in a CFV/CFVII , be used in a CF39II/H3D39-II/CFV-39 and vice versa ? ? ?

Has anyone ever tried this ? ? ? and if so , what is your experience ? ? ?

Starnge question to me. I use micro-SD cards for my smartphone on my camra and some time I use the free space to transfer video from one pc to another one and even use the card as back up for my Internet site.

By the way is there any advantage to use CF card as SD are more popular and allow 32Gb ?

For my Leica M8 I used only 4Gb sd cards, one day I got a phone with 16Gb micro-SD inside. 16Gb allows 1500 pictures in RAw at 10Mpix with Leica.

I have to use unpratical 2 CF card (of 4Gb) in my kodak proback
 
Formating for CFV39

Just put in the 4 GB or any other flash card, push the format button, and off you go. Same way I format my Nikon D2X card. No sweat ... simple and easy.
 
HELP ! ! !

I am misunderstood or asked a strange question .

I know how to format a CF card in my CFVI . I have done it many times .
And I know , I could use that card in any other device using the same type of card , format it and shoot .
So that is not the issue .

Therefore here the following scenario :
Assume that I have two backs . A CFVI or CFVII and a CFV-39 .
I formatted the CF Card in the CFVI and did a couple of shots .
Now I would like to add some images to that very same card , but using the CFV-39 . If I would format the card in theCFV-39 , I would loose my shots .
Can I use that card in the CFV-39 without loosing my previous shots .:confused:

As long as you skip the step of formatting the card in the CFV-39 you should generally be OK.

The problem is that digital back and camera manufacturers implementation of the FAT-32 filesystem (the guts of how information is written on the card in such a way that other computers and devices can read the data) is usually incomplete.

This means that if you use a computer or other device to write to that card (say to delete a picture), then pop the card back into the original device, the device may give an error (or worse, lose data) when writing to the card.

In my experience, this is entirely due to some assumptions (or shortcuts, if you will) that are being made by the device. This is why the safest thing to do is to format the card in the device you plan to use it in--this guarantees that all 'assumptions' made by that device are met.

Since the CFV backs are from the same family, it is entirely possible that Hasselblad re-used the software which writes to the card in both back models. (Why re-invent the wheel?) If so, both devices should be making the same assumptions, and thus you won't run into problems sharing the card between them without formatting. (It's also possible this software wasn't re-used...)

There's no way to know for sure but you can try shooting, swapping and deleting images for a while between backs to see if problems crop up.

Jürgen,


I know your plate is empty.

Who says my plate is empty as well?

I love pudding, can't get enough of it!

Hi Jürgen,

Just did a quick test with my H3DII and my wife's CFV. I can use the CF
card formatted with the CFV in my H3DII and the one's formatted with
the H3DII in the CFV.

BUT: I would agree with Brad and in general we format the CF cards
with the device the CF card is used for. Just good to know that it seems
to work between systems.

Funny enough, browsing images made with the CFV on the H3DII back, the image is displayed correctly but some noise pixels are created to fill the gap
between the square format of the CFV and the rectangular format of the H3D

Best Regards,
Ralf
 
BTW, I always read 4Gb card for Hasselblad, is it possible to feed biger ?
My phone has a 16 Gb micro SD. Is SD card not more confortable ?
 
I have 8GB Lexar CF which works very well. The 16GB are supposed to work
according to Hasselblad, haven't tried them personally though (but remember
some forum members use them).

Thank you Brad and Ralf for your contributions .

It is not my intention to swap cards forward and backwards between my CFV and the CFV-39 .
I will definately use one card per back and leave that card in that back .
I was thinking of an 'out of normal situation' , where it might be neccessary to use one card for two backs .

BTW , I use SAN DISK EXTREME IV cards , 4GB only and have several cards.
I do believe that working with 4 cards of 4GB is better than working with one card of 16GB .
But this might also be a question of personal preference .

I wouldn't be too worried about moving cards between devices, on occasion. It would make sense for Hasselblad to use the same software to write to the card in each back, so any assumptions that these devices are making should be the same.

The way to minimize risk (but not eliminate it) is simply to not delete anything from the card once it is written to by the digital back. This can dramatically reduce the odds of getting an error or experiencing data loss if you're swapping between backs or devices.
