Some SDHC cards mount-others do not

Inserting 32GB SDHC Lexar cards into this brand new iMac. The one that just started shipping a week ago.
The Lexar Platinum II 32GB SDHC 100x card has no issues.
The Lexar Professional 32GB SDHC 600x card will NOT mount. I tried two different cards.
I have the older iMac from summer of 2011 that would accept either.
This seems to be an issue with the new 27".
Anyone else experiencing this?
I read on a forum put the card in and put the computer to sleep, upon waking the card would be mounted.
I tried this and the computer would NOT wake from sleep.
Pulled the card from the SD slot and then the iMac would wake up.

Yes indeed! The iMac so-called SuperDrives seem to become choosy about what discs they recognize. Last year mine recognized a software CD (TaxCut) - this year it would not (H&R Block), it just spit it back out. Same problem with a particular music CD, worked last year not now. The drive recognizes another data CD just fine. Also will play a home-made DVD made on a combo VCR-DVD recorder/player. As I write this, it is now playing another music CD just fine. Apple should own up to this problem. The drive does not fail, its just becomes very particular (and unpredictable) about what it will accept or reject.

HP Pavilion dv6 card reader won't detect some SDHC cards

Notebook Hp Pavilion dv6-6104so
Windows 7 - 64 bits
The notebook's card reader won't detect some of our SDHC cards. We have updated the driver to the latest version, Realtek PCIE 6.1.7601.90, and the BIOS, but it still won't recognize some of our cards.
We have six SDHC cards, three SanDisk (4, 32 and 32 GB), two Kingston (8 and 8 GB) and one Integral (4 GB). The card reader recognizes four of them (4 and 32 GB SanDisk cards and one of the two Kingston cards). What is strange and that you may have already noticed is that the card reader recognizes only one of two cards with the same brand and capacity!
About the two cards that don't get recognized in our notebook, they work properly in their corresponding cameras and are detected without problems by another HP Pavilion dv6-3138so notebook card reader, as well as by two netbooks of ours from two different brands.
When we connect the cameras (one Canon and one Sony, both point-and-shoot) to the computer via a USB 2.0 cable, the laptop detects the cameras and through them we can access the cards.
We purchased the laptop less than two weeks ago in Helsinki, Finland.
Thank you in advance for your help!

Hey Everyone,
Using a high capacity card in a standard card reader slot will cause this issue. Im going to guess that the cards you ar having issues with are the SDHC cards and not the standard SD cards. As Naoto stated, by using a camera as a card reader you an workaround this. You can also look into SDHC card reader adapters. Here is a good article on the SDHC cards: http://goo.gl/lj5Fq
Hope this helps!

Problems downloading photos from my camera (Panasonic Lumix). Some will download and others will not with error message that they are the wrong format (jPeg)

Never had an issue before. Have installed latest software update and now only some of my photos will download. The rest will be recognized as a bad format (jPeg) and the camera will be ejected automatically, improperly, causing me to have to reboot the camera by removing the battery from the camera.

As a matter of fact. After giving my camera a complete charge, I have had
no more problems
That is why a card reader is so useful. You do not have to wait for the camera to charge and avoid the kind of errors above.

Is it possible to clear some (preselected) Overlays and other overlays not

Hi there,
I am building a VI that is called the rontgenanalyzer. THe purpose of the VI is to select points in an x-ray image to analyse the movement of the bones.
I am busy with the VI, but i walked into a problem that i could not fix. I created an overlay point on an IMAQ image to point out, the selected point, but the problem is that all the previous overlays of that point are staying in the image. So if you make a mistake while selecting a point, you cannot correct this because the 'old' overlays are also displayed in the image.
I already tried the IMAQ clear overlay function, but it clears al the overlays, but i only want to clear the ovelay that is selected.
Could someone please help me
thx in advance
Jens Dassen
Ps. I submitted azip with the VI and needed files so that you better understand what i mean.

You can't just edit them from Accounts>Preferences? Other than that, first quit Mail and make a backup copy of your entire Mail folder in your user Library/Mail. Move it out to the Desktop by holding the Option key down while dragging, for safekeeping.
Then, with Mail still quit, navigate to the user Library/Preferences/com.apple.mail.plist and move that file out to the Desktop for safekeeping, in case you want it back. You want to remove that file completely from its original locaton. For this, don't use Option-drag.
Now open Mail and you will get a new setup routine. I've gone as far as being presented with the new Mail setup, then decided not to follow through by putting the original preference file back, so I don't know if your old emails will automatically be present. But, if not, you will have the backup Mail folder from which to restore them.

Some Canon CR2 RAW Files Will Not Open In Elements 8

I use a Canon 7D DSLR. Up until 30 minutes ago I never had a problem opening Canon CR2 RAW files in Photoshop Elements 8.
Some files still open others do not. I can think of only one thing. I was shooting a large number of frames and reduced the RAW Image size down from RAW Large Only to RAW Medium with Small Jpeg to give me more room on the Compact Flash Card.
The Large RAW only CR2 files open fine in PSE 8, the Jpegs open fine, but the smaller sized CR2 files will not open and I get a wrong file type message in PSE8.
Any ideas why this would happen? I suspect it is a function of the camera setting, but all RAW files download as CR2 files.
I appreciate any guidance in this matter. Needless to say I am resetting my camera back to Large RAW files only.
Alex

ACR 5.x only supported full-sized 7D RAWs, but ACR 6.x supports 7D mRAW and sRAW, so just update to the latest version of the plugin, following the PSE-specific instructions:
http://www.adobe.com/downloads/updates/
sRAW and mRAW files are not RAWs because the camera has already demosaicked them to RGB and encoded them as lossless JPG.
Here is technical information on the reduce-sized RAWs:

Read SDHC card in 10.3.9

how can i read a SDHC card in 10.3.9 G4 power book?
I try to use exress card reder, but not work
thanks

Hi, tm001. You'll need to buy a card reader whose manufacturer guarantees its compatibility with the new SDHC card standard. Many older readers and other devices that can handle 1GB and smaller SD cards easily are incompatible with SDHC cards.

Will camera connection work with sdhc card

I just got a camera connection for my new ipad and I have a sdhc card and it is not reading it. Does it not support this card?

That certainly sounds like it is the correct setup. When I use my card with the iPad, it opens the Photos App right away. If a restart doesn't help, you may need to do a reset. To do that, tap and hold the Home button and the Sleep/On/Off buttons at the same time for approximately 10 - 20 seconds, until the Apple logo reappears. Release buttons. No content will be affected.

SDHC card exchanges

Hi
I recently bought asus transformer tf300 online on thanksgiving day. Along with that I bought 16 SDHC card for it
A day back received both of them and realized I was stupid to order SDHC card as it is not supported. I want to exchange it with microSD card. So is it possible to exchange and do i need.to pay extra as it ws bought on sale.price and as unfortunately I have opened the pack.
Any help is appreciated.

Hi achalrshah,
That's exactly right. You would get the full price of your initial purchase to put towards the new purchase. The difference in your example would be $20.

If you have an SD slot on the left side of your MBP it reads SDHC cards.

Packaged iTune gift cards, some in pack activated others not

I purchased a pack of iTunes cards for stocking stuffers. I know two activated at purchase of the pack because they have been redeemed. The one I gave my spouse will not work because it says it is not activated. If Apple packages the cards, then all of the cards should activate when they are scanned by using the package code. If all do not activate, this is an Apple issue. Customer service is unhelpful and Apple makes money for nothing. I have been victimized by inferior technology from Apple. I purchased a Mac yeas ago when nobody wanted them. I have purchased no less than seven iPhones and a couple of iPods. I have an iPad. I have redeemed iTunes cards and codes for years with no problem.
Apple customer service has always been excellent.
But, buyer beware on iTunes cards from now on Apple refuses to assist without a receipt and pictures of the card. If the card came from a pack that has cards that work, Apple should be able to activate the one card from the pack that did not. Apple created this system and it now seems part of the scheme is to defraud customers and receive money without providing a tangible reward.

I understand the reasons. However, the necessity for activation is in "very small print" on the back of the card. Cashiers are often poorly trained, and not everyone purchasing is as savey as the critical poster. Therefore I would advise that anyone not request this type of gift from any person who might not be as educated in the niceties of the purchase. In addition you cannot know that the equipment is functioning properly. Further my husband is advised by apple that the cashier also enters the amount of card into the system separately for serial numbers/type number so there is no assurance that the amount is correct. But at the very least the need for activation should be clearly marked on the front of these cards.

Sandisk SDHC card won't mount

Hey guys,
I am using a Sandisk SDHC 4GB card. It's referred to as Sandisk-Ultra.
For the first time ever, I tried to use it on my iMac. I directly inserted it in the card slot on the left hand side of the machine [iMac view] but it wouldn't mount.
I am running OS X 10.7.2.
I have never used an SDHC card before so I may not know some of the specifics.
Any help?
Thank you
Regards

Yup. It was the firmware. I need to download the new firmware from SanDisk on a PC with the reader attached, then it will work on the MAC.
Thanks!
Great computing. Another pesky case solved
Sometimes it's annoying having to use a PC to update the firmware. I had to use my Dell to update my Verizon router firmware. I wish the world would understand that PeeCees are not the only computers out there

How can I convert my music, and CDs to MP3, for use in my vehicle's AM/FM/ Stereo? I have a 16 GB SDHC Card, that I would like to load up with some of my music.

Thanks for any help you can furnish.

Well, this question really belongs in the iTunes forum, which is where you will get fast answers.
Just go to iTunes Preferences. Click on the General icon. Set When you insert a CD to Ask to Import CD. Click on Import Settings. Set Import to MP3 decoder. Make sure you're using Good Quality.
This should deal with your CD's.
With your current music, as long as it does not have DRM restrictions (older iTunes Music did), select the song, right click on the song (or group of songs), pull down to Create MP3 version.

Nikon D800 raw files taken with Sandisk extreme plus 32GB SDHC card got corrupted. Able to preview them in Lightroom4.4 Library, but not able to import or transfer the files from card to computer. Any ideas on how to save images from Library Window in Lig

Hi, I have shot few pictures on 31st December night in RAW mode using Nikon D800 and Sandisk extreme plus 32GB SDHC card. It looks like card got some memory errors so not able to transfer the files from Card to computer. However I am able to view the pics thru Lightroom ver 4.4 Library, but when I tried to import them, it gives me an error stating that file can't be read.
Is there a way to save the pics from Library window in lightroom overcoming the card read errors ?
Thanks in advance

Hi SSPRENGEL,
Thank you for your response. Here is the error message I am receiving, I tried with various destination folders in the computer but it still gives the same error:. Just to let you know, I am able to import pictures into these folders from other memory cards.
I am able to finally at least extract the jpgs using the option suggested by elie-d
