Question about Cameras

1 Answer

Hi, I have D90 standard package with 80-105 lens kit and I'm using it with 16 GB SD card. I'm using it almost a year now however last few weeks, when camera is on "off mode", little yellow light at the back of the camera (down right next to LCD) constantly twinkling. While I'm taking pictures, twinkling stops. And I assume because of this twinkling, battery dies after taking 100 pics. Do yo know the problem? Can you help me?

That is the card access lamp. It should light briefly when you insert a card and when you take a picture. If it's constantly blinking, something is wrong. Try removing and re-inserting the card. Try a camera reset with no card in the camera. Try downloading the pics to your computer and then formatting the card in the camera to completely erase it.

My lg does not read 2gb sd card.it tell me to insert a new one.Bt it can read 128 mb sd card


Your 2 Gb is not just an SD card, it is a SDHC card. The first 2Gb SD cards, still were SD, but 2Gb was the limit for the FAT 16 and 32 format and for the normal SD cards. The same happened with the hard disks. They developed the SDHC card, and made the new hardware downward compatible with the old SD cards. So in a new camera, you can insert SDXC, SDHC, SD and even MMC cards. But the cameras, card readers and phones, who were made for SD, can't use the SDHC or SDXC cards.
SDHC can work with memories up to 32 Gb and from that on, it is SDXC.
There still should be some 2Gb SD cards around, but not sure you still can fine one. The producers of memory cards now only make SDHC cards and up. Perhaps you only can get some 1Gb cards as SD card, but perhaps nobody will ever make these cards anymore.

I mannaged to buy a 4 GB SD card a few years ago, but that was the last I ever saw in the capacity. 25264488-uil2tdgcy05knvgzh4oup5lj-2-0.png

How to recover SDXC Memory Card


Storage is getting cheaper, smaller while offering higher capacity every year. 64 GB memory cards are extremely common in today's smartphones, digital cameras, tablets and media players. Due to their sheer capacity, a single failure can cause a local catastrophe with that much information being gone.

http://www.fixya.comwrite_tip-wyytcj10vubwvpdmj0eoj2yx-1-0_0.jpg

Fortunately, the market offers numerous data recovery tools that can help you get your data back. But there is something about these cards you should know before you reach for a data recovery tool.

Flash Chips: Riddled with Defects

Can you believe you can buy the whole 64 gigabytes of fast, high-quality solid-state memory for as little as $20, or does it sound too good to be true? Why is an SSD drive of said capacity three to four times as expensive as a much smaller SD card with similar capacity? Isn't it using exactly the same type of memory, just in a different shell?
In fact, you can't really buy 64 gigs of high-quality flash memory for under $20, and there is a good reason why SSD drives are that much more expensive compared to SD or micro SD cards. The answer is buried in the question itself. Why you can buy a 64 GB microSDXC memory card off Amazon for not much more than $20, the actual flash memory the manufacturer puts in these cards is of a completely different quality compared to that of a typical SSD drive.
So how exactly are manufacturers able to achieve these unbelievably low memory prices? They do smart tricks to make the memory card appear as 64 GB of contiguous space while in fact the actual chip is riddled with defects.
Each memory card employs a tiny microcontroller that maps flash cells to logical addresses. The memory chips are manufactured with abundant capacity. During the manufacture, the chip is tested for defects. Unreadable blocks are simply mapped out and become non-addressable and inaccessible from the outside. Bingo! We've just turned an imperfect chip into a perfectly usable memory card. These tricks are nothing shoddy; they are used by all SD card manufacturers, and they are part of the published SD standard. If not for these tricks, SD memory would probably cost the same (or more) as today's SSD drives.
Now when you know the truth about today's flash chips... can you trust them your data? In fact, you can. Granted, SD cards can sustain a much more limited number of write cycles compared to an SSD drive. When one or more data blocks reach their end of life, the built-in microcontroller of said SD card is supposed to take them out of circulation and assign their logical address to another (working) cell. But what if that cell contained some system information such as a part of a file system? If this is the case, the memory card becomes corrupted, and you'll need to use special tools to extract information from that card.

Recovering Data from SD Cards

Luckily, we have a large number of data recovery tools available on the market that claim to recover the entire content of your memory card. But were they really tested with any of those memory cards in their compatibility lists, or do developers simply assume the recovery will work based on the same principle as traditional magnetic media? In fact, I've seen both and in between. Some products can recover all types of SD cards as they claimed, some other tools can't deal with SD cards at all, while some other tools can only recover SD cards up to 32 GB.
Wait a minute... Why the 32 GB limitation? Why some of the tools can recover 32 GB cards, but fail miserably when reading a 64 GB one? Should the tool either work or not? The reality is more complex than the numbers. While SD memory cards up to and including 32 GB conform to the SDHC standard, larger SD cards (64 and 128 GB) conform to a different standard called SDXC.

Recovering SD, SDHC and SDXC Memory Cards: Is There a Difference?

There is in fact a big difference between smaller (up to and including 32 GB) and larger (64 GB and up) SD cards. The former conform to the SDHC standard, while the latter use the newer SDXC standard.
For you as a user this can mean two things.
  • First, if you are using a 64 GB memory card, make sure that both your portable device and your computer's SD card reader advertise support for SDXC cards (or simply put, they explicitly state support for 64 GB SD cards). If your card reader is old and can only support SDHC cards, you won't be getting anything but errors if you try to read that card with your computer.
  • Second, SDXC cards are formatted with a different file system. Let me explain. When SD cards initially appeared, they used FAT32 as a file system. FAT32 was good enough in the old days. However, this file system has inherent limitations, restricting maximum file size to 4 GB. Just a few years ago this would be a laughable limitation. Today, a typical HD video will already run you more than said 4 GB. If you try to save a large file onto a 32 GB memory card (formatted with FAT32), the write operation will fail.
This is why the SD consortium decided to use a different file system for the new generation of SD cards. 64 Gb, 128 GB and larger SD cards come formatted with exFAT.
exFAT is a new file system developed by Microsoft. exFAT is based loosely on the original FAT32. However, exFAT does not have the limitations of the older FAT/FAT32. exFAT is extensively used in portable electronic devices due to its lightweight design. This was one of the reasons exFAT was selected by the SD consortium as a standard file system for the SDXC format.
Are there downsides to exFAT? There's one, but it's a major one. While exFAT is designed and owned by Microsoft, it's not free. Microsoft requires manufacturers pay licensing fees for using exFAT in their devices. As a result, this has become a limiting factor for many portable electronic devices, especially inexpensive ones. This is one of the reasons why you can use 64 GB SD cards in some devices but not in others.
As a result, when recovering data from a 64 GB SD card, you'll need two things:
  • An SD card reader supporting SDXC (or stating explicitly that it can read 64 GB SD cards);
  • A data recovery tool that supports exFAT;
Not all data recovery tools can support exFAT because of the restrictive licensing model employed by Microsoft. Even if a tool advertises support for "all types of memory cards", it may or may not support exFAT. One of the tools known to support SDXC memory cards and exFAT file systems is Hetman Partition Recovery.

But I've Just Bought a 64 GB SDHC Card!

Sigh. This chapter is probably the most disturbing part of this article. Every other week, we receive an email from a customer describing a typical situation. Because there are so many reports, and because they all describe the same thing, let me just summarize it below.
A guy buys a 64 GB SD card for a price that's significantly below the market. When the memory card arrives, he tests it in his computer, discovering 64 gigabytes of usable capacity. Suspecting that 64 GB of flash memory for under $5 could be a scam, the guy tests the card by writing some data. The writes are extremely slow (3-7 MB/s), so testing the entire capacity would literally take the whole day. He writes some 1-4 GB of data and reads it back. All seems fine, so the guy formats the card and puts it into a phone, MP3 player, digital camera, or whatever portable device he bought it for.
Day after day, week after week the card is filling up with data. Pictures, music and videos are saved onto that memory card. 8 gigs, 16 gigs, 32 gigs, 64 gigs - the writes keep going, the memory card seems to be holding well. Then all of a sudden a photo won't show in a viewer, an MP3 file won't play, a video won't show up. The guy takes the card out and connects it to a PC in an attempt to save the rest of the data. But... oops! There are no photos, music or videos on that card, just garbage.
It is this moment the guy seeks for help and writes us an email. Sadly, in situations such as the one I described our hands are tied: that memory card was a fake. In fact, the "deal" advertises a 64 GB micro SD card for only $4.79. Yes, it's under five bucks for a 64 GB memory card. The description is Pidgin English and reads something like this: "New 64 GB Class 10 Micro SD HC Memory Card with Adapter Fast USA Shipping Dependable memory card for your favorite photos, videos, apps, and games Easily transfer files between phone, tablet and camera" blah, blah, blah.
Remember: if it seems too good to be true, it's probably not true. See that "Micro SD HC" designation? It's a dead giveaway. You can't buy 64 gigs of memory for $5. And, THERE ARE NO 64 GB SDHC CARDS, period. The SD standard dictates that all SD cards with capacities higher than 32 GB are made to conform to the newer SDXC standard. If you buy this card, you won't be getting anything but a fake.
Ditto. Do not buy these. Remember how the packaging looks, and ignore deals that seem too good to be true.

I can not put memory card inside the camera, this card is ritzpix 2GB. Can u please tell me what can be the problem?thank you


Your problem is that you are not using a suitable memory card for the D90. 2Gb SD cards have read/write speeds that are much too slow to work with quality DSLR's. Let me explain. When you take a picture with the D90, the data generated first goes into a small capacity buffer memory. The purpose of the buffer is to act as a conduit to your SD memory card and retain picture data until all of the data is safely written to the SD card. If your SD card can accept data as quickly as the buffer can pass it to the SD card, there is no problem. But, If the SD card is not capable of accepting the data quickly enough, the buffer will start to fill up since data is coming in faster than it is going out. If you take pictures in quick succession with a slow SD card or if you shoot video with a slow SD card, the buffer will overflow; i.e., fill to its capacity and become incapable of accepting more data until its capacity returns as the SD card accepts the data. During that time, the camera will prevent you from taking any more still photographs. You will push the shutter release and nothing will happen. If you are shooting video, the camera will continue to work, but the sound will loose sync with the picture.

For your D90 to function properly under all conditions, you must have an SDHC card that is rated at 45Mbs or faster. When I first bought my D90 several years back, 35Mbs was the fastest card made and I had the problems I described to you above. When Sandisk brought out the Sandisk Pro card with a 45Mbs speed my problems melted away. I should also ad that 2Gb is much too low of a capacity for the D90. It will fill up very quickly if you shoot Raw or fine quality jpeg files. You need a minimum of 8Gb.

I have a Polaroid i1032 10.0 megapixel camera. the user guide says that i can use up to a 1 gb SD memory card. I've used a 2 gb SD card and it works fine. My question is can I use SDHC cards 2 gb, 4 gb, 8...


At the time your camera was made, 1GB was the max size standard SD card. Then along came 2GB standard SD, but this card also used the same format as previous cards, so yes it also worked in your camera. Now SDHC is a very different format with different file handling (although externally it looks exactly the same). I'm sorry to say, it is very unlikely that SDHC will work with your camera. Here on Fixya you'll see many folks asking why the brand new card they just bought doesn't work with their older camera. 9 time out of 10, this is the reason why.

I recently purchased a 32 gb memory card for a Canon powershot sd 700 is Gigital elph. This is the second card I have purchased and I keep getting a memory card error message. The 16 gb card in the camera...


Here's the specs for your camera from Canon. Sorry, but an SDHC card is not listed as compatible with your camera. Only SD or MMC. Now look on your 16 and 32GB cards. You'll see SDHC stamped there. Although SDHC looks exactly the same as a standard SD card, the format the cards use are very different. Unfortunately your camera was designed before the SDHC format came out.
You'll need to instead purchase a standard SD card (those that are 2GB or less). Fortunately these are very inexpensive these days, with 2GB cards going for around $6 with shipping.

Camera will not accept any memory card over 2GB. Keeps saying "Memory Card Error"


Most new 4GB and larger cards are SDHC cards (look on the card). Although they look exactly the same as a standard SD card, they are not. Unfortunately, there is no way that these cards will work with your camera, as it was designed before the SDHC format came out. As you've dsicovered, 2GB and less are standard SD cards, and will work with your camera.

There were a few standard 4GB cards produced a few years ago, most notably by ADATA (I have one that I use in my A620). Unfortunately, these are rare now, and are somewhat expensive if found on eBay.
