Apparently yes: Police announced that part of the SD Card has since been discovered in Wakita's body (some Japanese blogs are reporting that they found it in his, ahem, poop). On the recovered card, officers apparently discovered the peeping pictures in question and arrested Wakita. They are pretty durable things. It sounds like in this case the guy ...

Let's do a little cost benefit analysis: A journaled file system is more complicated - this means longer development time, more bugs, more battery power drain, higher production cost etc. the problem solved by a journaled filesystem - corrupted FS data but file data intact - is handled pretty well by 3rd party data recovery tools. journaled file system ...

Fundamentally they are the same thing in a different package but they work differently. SD cards use their own protocol which was extended to go beyond 2 GB up to 32 GB with the introduction of SDHC (there were a few 4GB SD cards but not very compatible) and then to support up to 2 TB with the introduction of SDXC. The SD to SDHC transition if you remember ...

Initially the reason was performance and capacity. A lot of the pro-level cameras went CF because you needed the performance and, usually because a pro shoots RAW, the capacity which the original SD couldn't match. Not to mention there was a point in time where SD was more expensive as a result of volume sales differences. SD is now cheaper thanks in a big ...

I can't speak for Linux, but on Windows I've used the excellent "Recuva" product from Piriform to recover deleted files. Recommend giving that a go to see if the content is still retrievable and as Reid said - if there were more photos taken afterward then she's almost certainly up the creek.

It depends. My last camera only connected at USB1.1 speeds, so was slower than using a USB2.0 card reader. However, if your camera can do USB2.0 or you have a USB1.1 or USB1.0 card reader, you wont see that benefit. You can get Firewire or ExpressCard card readers for CF cards, which are faster than USB2.0, (and I think generally limited by the speed of ...

Check out TestDisk or the associated PhotoRec tool from CGSecurity. TestDisk will allow you to scan the file system and look for deleted files. (See How to Undelete files with TestDisk.) Provided the data hasn't been overwritten it should be possible to recover the files. You can also use TestDisk to take an copy of the underlying file system to stop any ...

Most high-end SD cards from a good brand are waterproof. It will survive submerging in a fish tank for weeks, acid proof or not, I don't know. Generic brands or low-end cards are not as well constructed and are NOT waterproof. However, taking the question seriously, since the card ultimately comes out with your waste. I think it would be better to wrap it ...

Mostly because CF has faster read/write speed than SD card. SDHC has a higher capacity (more space) but not necessarily faster read/write speed. Some high-end CFs allow parallel read/write (the interface allow this), but not SD/SDHC. So some high-end camera usually take advantage of this in combination with their buffer. Now Rob Galbraith did lots of test ...

I successfully recovered all the files from a formatted card by copying it using dd and then using the sleuth kit under linux. Fortunately no pictures had been taken since the card was formatted. I used the fls and icat commands as described in test image results from Sleuthkit Informer Issue #14 and the TSK Tool Overview

Journaled file-systems only ensure the integrity of the file-system. If a card truly fails, it fails with the whole file-system. Now if you have some bad memory cells, you would only use whichever photo occupied that space and a journaled file-system would not help either. In other words, this is the wrong solution to the incident you describe. The real ...

CompactFlash came out in 1994, while Secure Digital came out in 1999. Five extra years of adoption helps explain why higher-end cameras support CF over SD (and vice versa). Pros tend to standardize; they buy a lot at once, have supporting equipment to match, and don't want to switch frequently. Thus professional standards have higher market inertia, and end ...

Short answer: no. Long answer: no. Your Fujitsu point and shoot camera has a much lower throughput than your card's max, so the bottleneck with shooting lots of pictures very, very quickly will be the camera itself, not the memory card. Additionally, there will be absolutely no difference in image of video quality... this is digital after all.

There is an advantage to Compact-Flash cards which you get with the fastest models and sufficiently fast camera. This is not what accounts for most of the price difference, volume is. SD cards are sold on considerably higher volume than CF ones. When CF cards were more popular, it used to be the opposite. Nowadays, I would not worry at all about this. The ...

The GoPro HD Hero 2 states on the FAQ page: You will need to get a class-4 or higher SD card from a reputable brand and source in order to use the camera effectively. A class-10 SD card is recommended when using Time-Lapse mode or photo every 0.5 seconds. Class 4 isn't that fast by today's standards, and actually equates to 4MB/s read/write speeds. The ...

The short answer is that it doesn't really matter. The "protected area" is not important for photography; I'm not aware of any camera that uses it. This area is theoretically used for user-hostile copy protection and is not really for your benefit in any case. When using your camera to store photos, you can just ignore it. The concern about less than ...

The speed of the memory card is definitely one constraining factor but as you suspect there are other bottlenecks. First there is the internal memory buffer of the camera. Each camera only has so much RAM installed. When you shoot this buffer is filled first and the camera does what it can to quickly empty the buffer to allow for more shooting. The size of ...

There are several ways in which an SD card can go bad. Physical Damage First, cards can be actually physically broken. You can bend them in half pretty easily if you try, but in general they're actually pretty resilient. Many are effectively water-proof even if not marketed that way. I've sent cards through the laundry, and once I dropped one full of ...

There are two apps I have tried that worked for me: Ontrack EasyRecovery - Very good, comprehensive and reliable. Got me out of trouble more than once. Unfortunately a bit pricey. Windows only. The Lite version is good enough for you as it can recover up to 25 files. Sandisk RescuePRO - Not as comprehensive as EasyRecovery but gets the job done and is ...

And since this thread has now been resurrected, I'd like to add another reason that I'm surprised nobody has mentioned. Pro cameras tend to use Compact Flash because pro photographers prefer the size of Compact Flash cards. They're bigger, easier to handle with gloves on, harder to lose. They're also perceived as being tougher due to the size. Whether or ...

First make sure the metal contacts on the card are clean, and reformat the card in the camera using the menu. I assume you've done these things but it doesn't hurt to double check. Since you get the same behavior in both card slots, it seems likely the card is damaged. They are relatively cheap — get a new one, preferably a higher-end name brand. If you ...

I'd expect it to survive. Stomach acid is reasonably nasty stuff but residence time is not vast. You could try it now so that you know when needed. Swallow an SD and a micro-SD at the same time. Anyone looking is more liable to find the SD and may stop at that stage. Even if connections or PCB were damaged I'd expect the memory proper to have a good ...

The problem is that those reasons don't apply and if they did more consumers would be willing to pay out for better cameras with those features and the others that come with more expensive kit. If an SD card becomes corrupt, an amateur has plenty of time to change cards and less need to guarantee capturing the action such as at an event. If an amateur ...

The main disadvantages are: Slower speeds available in the microSD format as compared to full size SD Additional cost of the microSD format The addition of another piece that can fail, be lost, etc. The microSD cards are so small that some people are afraid of losing them or breaking them easily In today's market, the first two points are typically less ...

I would strongly recommend getting a new card. The danger to the camera, ultimately, is that it gets stuck in the slot because of the card seperating. While I would imagine that Nikon repair could sort that out, it may cost you a lot more than a new card to have it done because such a situation would not be warrantee.

If you observed the Extreme Pro is in fact faster than the Extreme than that does answer your question (it answers the faster part, we already know the cheaper part). If you have both cards you can always run a test, just set the camera to burst mode and hold the shutter button - this will tell you the maximum burst length for each card, or, if you don't ...

This depends on a number of factors but, in general, it would be true. The primary reason is that many readers are not attached via USB and so are not limited by the speed of the USB bus and are also not sharing the bandwidth of the USB bus with other devices. However, if your CF reader is USB, it wouldn't likely be much faster, if at all. Anyways, it can be ...

Some professional DSLRs do support SDHC, such as Canon's 1Ds Mark III. Historically, Compact Flash offered higher capacity with miniature hard disks, although with advances in flash memory, solid state media has long overtaken it. Manufacturers don't want to give any excuse for photographers from upgrading, so tend to carry on supporting CF.


5

I guess in part because CF cards are bigger, and so it's easier to develop faster and larger quantities of memory in large-sizes, before scaling down to the smaller SD cards later on. I think the added bulk and resilience of the more substantial CF cards. I'd imagine most of the professional camera body users also have a fair amount already invested in CF ...

I'm going to answer a different question. :-) Instead of planning to strain my poo for the next few days, I would happily format the card and show the goons. What I would be wagering is that they would not realize how easily one can recover images from a freshly formatted card. If that weren't good enough, I would voluntarily remove the card and give it ...
