View Full Version : Data on CF B needs recovering. Attempt to recover?
Jim Martin October 16th, 2010, 05:07 PM We were shooting today and every 3-8 minutes, this would pop up. The manual mentions this as a recovery tool when a card has been ejected while recording or if power cuts out while recording, but neither was the case. We would say yes, just to be sure, but then it would "recover" and then stop the filming. It's very odd. Anyone else have this problem?

Doug Jensen October 16th, 2010, 05:27 PM Sounds like a sub-standard card.
What was it?
I had a SanDisk Extreme Pro give me that error during overcranking and now I will only use Hoodman cards.
FYI. whenever you are fprced to let the camera try and recover the card, you risk losing EVERYTHING on the card.

Doug: a "SanDisk Extreme Pro" is NOT a "sub-standard card."
A reasonable starting point for card selection is the list of cards
Canon Professional Network - CF card compatibility for XF305 and XF300 pro camcorders (http://cpn.canon-europe.com/content/news/CF_card_compatibility_for_XF305_and_XF300_pro_camcorders.do)
Google for "canon xf300 approved cf card" if this URL does not come through.
I do NOT see "Hoodman" in the "Canon XF305 and XF300 camcorders: CF card compatibility " list. But I do read "Canon cannot guarantee operation of third party CF cards in all circumstances." So by Canon's word, your "Hoodman" card is "sub-standard" even if it works for you; a SanDisk Extreme Pro" has been tested by Canon and "Works with all recording modes". Please stop spreading FUD.
Anyway, Hoodman does not manufacture CF cards, and there are known to only be a few CF card controller chip-makers. Hoodman could be a rebranded Sandisk for all you know :-)

Doug Jensen October 18th, 2010, 05:01 AM Brett,
Obviously if the SanDisk card failed during overcranking then it is a sub-standard card. Period. There's no arguing with that. I was not doing anything unusual with it, pushing the limits, or anything out of the ordinary. The fact is, it failed and I even captured the failure on my NanoFlash if you'd care to see it fail.
I don't care if Canon, SanDisk, B&H, Consumer Reports, or anyone else puts their stamp of approval on it. 3rd party recommendations mean nothing when compared to my actual experience.
And are we going to take Canon's word for it? They couldn't even get the XF Utility software written without major bugs, and it is going to take months to release an update. Is this who you want to take advice from on cards? Canon[s recommendations are just a starting point anyway, and even Canon would not say it covers all the cards that are compatible. Why doesn't Canon produce their own brand of cards that they can get behind 100%? Panasonic has their own cards. Sony has their own cards. Why doesn't Canon produce their own cards, even if CF cards are widely available technology from many sources? The card itself is such a critical link in the whole recording system that you'd think they want to have a little more control over it.
I've been shooting on XDCAM since 2006 and have never had a single failure of any kind in all those years. Yet, on the XF305, I experienced a failure within the first 6 weeks. I want that same reliability out of the Canon that I've had with my XDCAMs. Is that so much to ask for?
I've shot tons of overcranked footage on the Hoodman cards and they have never failed. They also import 20% faster than the SanDisk card. In my book, that makes the SanDisk a substandard card. If you have a problem with the term "substandard" then let's call it "inferior" instead.
Getting back to Jim's problem, he didn't say what kind of card he was using, so I stand by my initial assessment that he's using a substandard card -- and I'll hold to that opinion even if it turns out he's using a card that Canon recommends. A card that results in frequent error messages is a SUBSTANDARD card.
I don't know or care how Hoodman manufactures their cards. They say they are built to higher specifications and with better components than other cards, and from what I have seen, that is true. Until I have a Hoodman failure, they have my full confidence.
Jim Martin October 18th, 2010, 09:46 AM Hey thanks for the responses.....it is a Delkin 16gb 450x card.....we're trying to figure out if we have a bad card or a bad camera. We'll do a test with a Hoodman 675x card and I'll report back later.

ps- We were recording our seminar on the new Cube wireless transmitter so we can put them up on the web for everyone.
Jim Martin October 18th, 2010, 01:10 PM Well..........we put in the Hoodman 8gb 675x for 20 mins and......no problem. Looks like we are going to be safe and spend the money for the Hoodman cards.

Mark Moreve October 18th, 2010, 01:46 PM For my 10 cents worth on this conversation.I'm yet to have a sandisk problem but I have heard that the Hoodman cards are meant to be great. As in more reliable and faster write and read speeds.
Jeff Anselmo October 18th, 2010, 02:04 PM Hi Jim,
Sorry to hear about your CF problems.
I agree about using the "best" possible media with your camera. And I really appreciate the work and tests of other XF users regarding cards. Real world applications can't be beat (that's why I ended up buying 2 16G Hoodman CF cards as Doug recommended).
But I am still curious what other brands work with the XF cams. Hhmm. Wonder if the Delkin Combat CF cards (rated at 91MB/s and 625x) would work?
Brett Delmage October 18th, 2010, 08:47 PM Brett,
Obviously if the SanDisk card failed during overcranking then it is a sub-standard card. Period. There's no arguing with that.
Not to be pedantic, but I believe you mean "defective", unless you can cite the timing specs that the card is failing to meet. I think you then overgeneralize that specific failure to all cards by that manufacturer without basis.
I don't care if Canon, SanDisk, B&H, Consumer Reports, or anyone else puts their stamp of approval on it. 3rd party recommendations mean nothing when compared to my actual experience.
It is your clients and your work so you get to pick your tools. Nobody is arguing with that. We also welcome hearing about your experience.
I could say, just as strongly that your recommendations mean nothing when compared to my actual experience - years of experience using Sandisk and Lexar cards without a single failure.
And are we going to take Canon's word for it?
So far, I've seen you complain based on one single failure. Have I got that right? I am not denying that failure is not real, but statistically it means nothing.
They couldn't even get the XF Utility software written without major bugs,
Now this is a red herring. Sorry, this is a meaningless statement when referring to the CF card situation.
Furthermore, it is unlikely that people developing software for a PC application had anything to do with the camera development. I say that as a software developer who worked for 25 years in companies that developed both firmware-based hardware, and software-based products. In one case, I worked on a firmware-based product, with another employee who worked on the associated PC software. His software and its bugs in no way affected my firmware reliability. (Coincidently, I wrote software to use, erase and write Flash memory in that device, 15 or so years ago.)
Is this who you want to take advice from on cards?
Actually, yes. In my opinion Canon has likely spent a lot more hours using, testing and qualifying CF cards than you.
Please show me where Hoodman states that their cards have been tested on the XF-30x cameras and are standing behind that use?
Canon has posted their list on the web. Their reputation and sales stand to suffer if the cards they recommend do not work reliably in their camera.
even Canon would not say it covers all the cards that are compatible.
We can agree on that. I'm sure they wouldn't know all the existing and future small-scale manufacturers of storage, and they would want to test and recommend cards that are widely available.
Why doesn't Canon produce their own brand of cards that they can get behind 100%? Panasonic has their own cards. Sony has their own cards. Why doesn't Canon produce their own cards, even if CF cards are widely available technology from many sources? The card itself is such a critical link in the whole recording system that you'd think they want to have a little more control over it.
You've touched on a key point: the card IS critical. Now, if I remember correctly, the Panasonic cards are NOT CF, they are a completely different storage architecture. Unless I am mixing them up with the Sony, their cards are actually internally redundant - effectively a RAID 1 storage system - which, as far as I know is way beyond anyone else. As is the cost!
I think many have already spoken in this and other forums about the cost effectiveness and convenience of being able to use mass-market CF or SD cards for camera storage. I think that is the answer to your "why". Users may value high reliability but there is also a limit to our budgets.
I've been shooting on XDCAM since 2006 and have never had a single failure of any kind in all those years. Yet, on the XF305, I experienced a failure within the first 6 weeks. I want that same reliability out of the Canon that I've had with my XDCAMs. Is that so much to ask for?
I do not believe anyone here wants to risk losing unrepeatable footage because of a media failure. I'm sure that would be a nightmare to all of us.
Please remind me again of the cost of your Sony media (at time of purchase), and the cost of your failed Sandisk CD card?
Have you received any consideration or discount from Hoodman, or are you just a happy user? You mention them frequently in a forum where marketing is supposed to be prohibited; it makes me uncertain.
I'm just a user. No discounts, deals or consideration from any supplier. I wish though! :-) I spent a grand on CF cards in August and I sure hope they are not too sub-standard ;-) Or defective. I have allegiance to no manufacturer except the 'best' one.
cheers,
Brett
Josh Dahlberg October 18th, 2010, 09:17 PM I have several Sandisk Extreme cards but I'm paranoid about losing footage so I ordered a Hoodman 32gb just to be sure. Though rare, some users report Sandisks failing: I've never read of a Hoodman card failing. To be fair though, there are so many more Sandisk cards in circulation sheer volume could be a factor.
A word of caution on the Hoodman 32gb CFs: on Hoodman's site they are listed as Type I. However, I purchased one from B&H that turned out to be the thicker Type II - it won't fit in the XF.
This is really annoying - B&H don't specify in the listing that it's Type II, there's no mention of Type II either on the packaging or on Hoodman's site. I'll have to return it but I've already paid shipping and import duties. So just be doubly sure you're getting a type I card if you order Hoodman.
Steev Dinkins October 19th, 2010, 01:01 PM This thread is quickly getting messy, so sorry if this is redundant, but in my testing, there are perfectly working high quality cards that simply just won't work for long recording times with this camcorder. It's unfortunate but true. I've seen faster cards fail while drastically slower cards were totally reliable. It's not necessarily about good or bad cards. I suspect something else going on with the structure of the card and how the Canon writes to it. Bummer. The trick is getting cards that work reliably.
Lastly, I've found that when you see the recovery attempt warning, it means that it couldn't write to the card anymore and if you see that message early on, you won't have lost much. Bottom line is when it chokes, that message comes up. If you didn't realize it till say 5 minutes after the fact, you're screwed - that 5 minutes is gone. So, best to keep your eye on the camera - which is usually the case. But lastly, again, establish through long recording testing that the card is reliable.
My troubleshooting with incompatible cards has been confirming a specific time length that would consistently fail to record past.

Steev Dinkins October 20th, 2010, 12:34 AM Steev, are any of your cards that don't work on Canon's approved list?
Nigel, no, none of the non-working cards are on the list. That is to say, I have not found Canon's list to be in error. But I am surprised that the camcorder is so picky. It's not a data rate issue, it's something else.
All cards tested have passed a lot of other tests with other tools. And work fine in other devices.

-steevAt least it's reassuring to know that whatever the reasons one can at least rely on Canon's list of blessed cards or at least know not to rely on any card that is not on the list.
James Redmond October 20th, 2010, 08:20 AM I have 2 cards:
ScanDisk Extreme Pro 64 gb
Adata 533x 32 gb
I do long recordings. I do not overcrank.
Luckily I have not had any errors on either one.
All the best, James

Matt Katz June 12th, 2012, 05:52 PM I bought a Lexar Professional 400x 64GB UDMA 7 and after a few minutes I'm getting the same message, which is very discouraging since I had the XF100 two weeks before I could afford to buy a CF card.. Now I'll have to save up again for a Sandisk
Josh Dahlberg June 12th, 2012, 05:58 PM Matt,
B&H have the Sandisks at a great price right now, just bought a bunch of them myself (have been using these with my XF300 for nearly 2 years now without a hitch).
SanDisk 32GB CompactFlash Memory Card Extreme 400x
Matt Katz June 12th, 2012, 06:45 PM Thanks, Josh. B&H is sold out right now but I'm on the notification list...
Steev Dinkins June 12th, 2012, 08:00 PM Yep, the XF camera's pickiness regarding CF cards is a big DRAG. At the moment I'm only buying SanDisk. 32GB and 64GB. Although I have several ADATA 32GB cards that work great. I have some 16GB Lexar's that work, but the 32GB don't - BUMMER! Oh well, I guess SanDisk has something to be happy about.
Matt Katz June 27th, 2012, 12:43 PM I received a Sandisk Extreme 400x 32gb compactflash card from Newegg on Monday and, sure enough, it works perfectly. No more "Data needs to recover" text. Thanks for the help, y'all...

Hi, I've had the same error & l am wondering if you we're able to recover the data. I've never had the error before but i was trying to quickly change batteries during a shoot & l think that's what's caused the error.
I haven't tried to recover the data as yet as I'm a little nervous about if it will work. Can you please let me know if it worked for you??? Or if its best to take the card to a data recovery place???
Brett Delmage November 18th, 2012, 02:24 PM I haven't tried to recover the data as yet as I'm a little nervous about if it will work. Can you please let me know if it worked for you??? Or if its best to take the card to a data recovery place???
Definitely *allow the camera to recover the data*. Only the camera knows the data formats. A data recovery place will only know about the VFAT filesystem, not the Canon MX journaling, etc that is used for recovery.
If you are really nervous, put the card into a card reader first and copy the complete card to a backup folder on your hard disk first, before putting it into the camera for recovery.
My XF-300 has done recovery at least 5 times without failure.
Just make sure you select the choice to recover, when asked.
I was saved by an unusual recovery in August. I started editing footage the day after an evening shoot and the audio and video was misaligned. it was an unusual mess.
I went to a shoot that night and when I turned the camera on, it asked if I wanted to recover. It did, and it produced usable clips from the previous night. I set the cards aside and used others. Fortunately, I had somehow not downloaded and wiped the cards right away as I normally do. Sheer luck! I lost no footage. I have no idea what caused the corruption in the first place, except absent-mindedly turning the camera off while still recording? (No, I don't do that as SOP!)
Best of luck,
Brett
Belinda Bowey November 19th, 2012, 12:56 AM Hi Brett,
Thanks so much for your reply...l stressed about it all weekend and then got up enough guts to just turn my camera on and l didn't even get the message...all the data was there except for about 18minutes, which l was very relieved about. I can pinpoint where the files were lost and their numbers and now l'm trying to find some recovery software to fix it.
I have tried a few programs, but nothing is getting me the results l'm after.
I've tried RescuePro Deluxe, nothing...
Stellar Phoenix - Nothing
Card Recovery Pro - Nothing either...
Any suggestions on what l can use ?
Martin Catt November 25th, 2012, 11:38 PM I got the dreaded Data Recovery question a couple of days ago on my XF300 using 32 gig Duracell-brand Pro Photo 600X cards. I'd purchased two on sale. Fortunately, it was on a test I was running, something non-critical. I got the same message using both Duracell cards, switching them between both CF slots on the camera, so it isn't likely to be a single defective card. Each time, the camera appeared to be functioning properly, but after hitting the button to stop recording, the camera took considerably longer to display the STBY on the display than usual, then popped the warning. As near as I can tell, the data recovered completely with no losses, but I decided it wasn't worth the risk. The Duracell cards are now marked for exclusive use on my 5DMk2 only.
I bought a 32 gig Sandisk Extreme when I got the camera, which has given me no problems. On paper, the specs for the Duracell cards are identical with the Sandisk, possibly even a bit better on write speed IIRC.
I did buy a couple of 32 gig off-brand 600X cards the day my camera arrived, a brand called Silicon Power. Frys had them on sale for less than half the price of the Sandisk. I bought them on the odd chance they would work, and would use them for the 5DMk2 in case they wouldn't. The Silicon Power cards have worked perfectly, even though they cost LESS than the Duracell cards. I have no idea who Silicon Power is, never heard of them, but they've been reliable through heavy use. It could be that SP is sold by the same silicon foundry that makes the higher-end cards for the name brands.
I think the difference is in the internal firmware the cards use to distribute "wear" on the memory cells. Every time you write to a storage location, it damages it slightly, and after a sufficient number of writes, the cell will fail. I'm told the number of write cycles before failure has at least six digits in it (reading the card supposedly doesn't cause any damage). The cards have built-in logic that automatically shift the write locations each time, transparent to whatever device is using the card, so the "front row" locations don't get worn excessively.
