    I saw a deal posted here for Sandisk 32 GB CF cards from B&H... I recall it expired on 04.25 --- did that message get deleted? I can't recall the specific terms of the deal, but I thought it was a 2 for 1 -- anyone remember?

    Also, when B&H make such offers, they seem to offer something called a "$100 rebate." What exactly is this, and how does one take advantage of it?

    @filthy I got that SDXC card reader a few months back: http://www.ebay.com/itm/250915332288

    Works fine, although it was a bit cheaper then. YMWV.

    ah nevermind, I just found the description in the FAQ ( http://www.personal-view.com/faqs/gh2-usage/gh2-usage )

    guys sorry for the noob question, but I can't translate "Spanning" in my language, can you please briefly explain me what span is ? Thanks

  • filthyfilthy

    @thepalalias, @blazer & @mo7ies - Thanks for the tips. Tried and failed to transfer footage over on an old laptop running XP. Will have to run into town tomorrow to see if there are local options for newer card readers. If not, guess will be ordering online. Figured this kinda thing would happen in the middle of a week-long project!

  • alcomposeralcomposer

    @balazer going on experience the GH2 uses FAT32 on a SDXC card... however there may still be parts of the card that are exFAT... I am not a Memory specialist so I can't answer your questions. Suffice to say that I didn't have any love with my laptop and SDXC. There is always the possibility that I got this wrong. :-D In that case my bad. Can someone chime in Yay or Nay?

  • balazerbalazer

    What do you mean the underlying system is still exFAT? exFAT and FAT32 are two different filesystems. A volume can only be formatted in one or the other.

  • alcomposeralcomposer

    Sorry @balazer, they are NOT reformatted to FAT32. They are formatted 'over' with FAT32, the underlying system is STILL exFAT. I had an older file system with a SDXC reader and it was not joy... :-( Plus this is stated in Apples release notes for 10.5 and 10.6 (I believe 10.6.4 is the first time SDXC is supported) YMMV

  • balazerbalazer

    alcomposer, no, only 'new' OSs support the exFAT filesystem. But when you use an SDXC card in the GH2, it gets reformatted in FAT32. This isn't an operating system issue. It's a host device issue. He needs an SDXC card reader.

  • leonbeasleonbeas

    @mo7ies yes i've just put two of those 64gb cards in shopping list, its always better to have more than less, its an inversion.

  • alcomposeralcomposer

    @filthy only 'new' OSs will read SDXC. (Example- Mac 10.5 won't - but 10.6 will)

    So don't be fooled into thinking that its a 'bad' card. 64 gig has been my most robust card... and with the $15 price drop I may get a few more... ;-) (Still Cheaper than SSDs!)

  • mo7iesmo7ies

    @filthy - my card works fine on either of these two readers, connected to the USB 3.0 hub and then into my video PC workstation (win 7 x64):

    http://bhpho.to/I4qyJw

    and

    http://bhpho.to/Id35EZ

    It was also fine in my Vaio laptop that has an ancient built-in SD card reader. So I'd say something must be off in your setup?

    @leonbeas "its better to loose 32Gb of data due to whatever may happen, than 64GB. Did you have any problem with the sandisk SD cards?" - never had a problem with any SD cards. Except last week my Transcend 16Gb Class 6 became unreliable - it would not read in one of the USB readers after the umptieth long timelapse put on it with thousands of images each. Still, I was able to read it in another reader, got all images off of it fine, and just retired that card as a precaution.

    While I agree in general that smaller media size prevents large data loss... in practice... the problem is data management: if you have too many cards, it becomes a nightmare, especially on location. Then you get operator's errors and - guess what! - data loss :) So IMHO it is better to take a chance and have 2hr+ recording on this 64Gb bad boy, than to try and wrangle 32Gb cards !

    Price just fell by $15 !! http://bhpho.to/I0B8Tj

  • balazerbalazer

    filthy, you need an SDXC card reader.

  • thepalaliasthepalalias

    @filthy It's more finicky than others cards - seems to have something to do with the 64GB aspect.

    Without knowing what card reader and OS you are using, it is difficult to give specific advice, but normally I just use a different card reader when I have a problem. That may actually be enough to solve it, but if it doesn't you can provide more details and someone may have more specific advice.

  • filthyfilthy

    Finally broke down and bought the 64GB 95MB/s card. However, I'm having issues using it. Loads, formats and shoots fine in camera. However when inserting the card into a card reader, my computer states that the card must be formatted prior to use. Otherwise, it won't even recongnize it. Obviously, doing so clears the card of all contents and losing any footage. Problem is when inserting the card back into the camera, it won't work as is. The camera gives a message that the card must be formatted prior to shooting. So camera formatting and computer formatting appearing to be conflicting with each other. And round and round we go. I normally never format via computer. In camera only. No issues on any prior cards (older transcends or sandisk 30MB/s). Read through everything here and didn't see any mention of others experiencing similar issues with this card. Am I overlooking something simple here?

  • thepalaliasthepalalias

    @leonbeas When I have data for both the cards I mentioned above with EOSHD 88, I will let you know. My guess is that the SanDisk 32GB 45MB/s would perform somewhat similarly to the Delkin 16GB 95MB/s (with the latter performing slightly better). If it works on that Delkin card, there is a decent chance it could work on the 32GB 45MB/s.

  • leonbeasleonbeas

    So even if i want to go for example eosHd 88 unified you recommend 64GB 95Mb/s card.

    My only concern apart from price is that I believe its better to loose 32Gb of data due to whatever may happen, than 64GB. Did you have any problem with the sandisk SD cards?

  • mo7iesmo7ies

    This 64GB 95MB/s SDXC card spans my Sanity 4.1 vids in 24H mode!

    This was not happening with 32GB 45MB/s SDHC SanDisk. So here, me happy! :)

    @leonbeas It is not just a matter of bitrate, each setting (Sedna, Orion, Mysteron) is different, and each mode (24H, SH, FSH, HBR) is different. Also, for anything but 24H, 80%, 200%, 300%, the results may be different for PAL and NTSC.

    Here is a look at some recent spanning tests I did with a Delkin 16GB 95MB/s and a SanDisk 64GB 95MB/s. The performance of the cards you listed should be closer to the Delkin 16GB. http://www.personal-view.com/talks/discussion/comment/56746#Comment_56746

    In terms of spanning in 24H mode, unless you have a 64GB SanDisk 95MB/s, I would try the next set down (Rocket, SpanMyBuV2, Picturis) to see. I have used Sanity 3.1 and SpanMyBU v1 for that in the past but haven't needed many shots that spanned more recently.

  • leonbeasleonbeas

    Ok Hi there everyone so after reading a lot, i have some questions.

    What is the highest tested bitrate that the 32Gb 95Mb/s can handle with spanning working, and no errors?

    And what is the highest tested bitrate that the 32Gb 45Mb/s can handle with spanning working, and no errors?

    Can you please advise on what better quality patch to work error free on any of above cards?

    And last how much footage (min) can i fit on those cards, using the recommended patches?

    Thanks a lot to all of you spending hours testing, and sharing your time and knowledge to all of us?

  • nomadnomad

    No, the GH2 doesn't use exFAT.

  • adamquesadaadamquesada

    I'm going to ask a stupid question here since I am not sure if it has been brought up:

    Comparing the Sandisk 32GB 95MB card to the Sandisk 64GB 95MB card is the filesystem.. The SDXC card uses exfat.

    Could it be that the SDXC card is spanning due to exfat supporting larger than 4Gig files and thus not even needing to span?

    Does anyone know if spanning will always happen even if the card is exfat?

    Has anyone tested spanning on a slower Sandisk SDXC 45MB card?

    @balazer. Got it. Thanks!
