OS X :: IMac Card Reader Corrupts SD Card

Dec 4, 2010

I've had a pleasant experience with my imac so far, and it read my SD card fine at first. For some reason I put my SD in the SD card reader and copied the pictures from it. I take it out and put it back in my camera. "The SD card cannot be formatted. It may be defective." Really? I put it back in my iMac. It doesn't mount. I check Finder and Disk Utility. Ya, it's nowhere. I put my other SD card in my iMac. Same issue. Now my camera won't read that one either. I put them in my sister's $300 netbook running Windows 7 Starter. Funny! It reads them! However, my camera still doesn't and my imac still doesn't. I try formatting them. No go. I've tried every format I can. They are just dead. Useless. My sister's computer can read them, and even format them, but something in that stupid iMac made my SD cards defective. I can buy new ones, but should I have to? I can't even see if they'll work through the camera while connected via USB because the camera won't even read them. I bought a Mac to avoid ridiculous problems like this. Was I wrong? Is it just a ticking time bomb like every other computer on the market? Should I immediately go buy a backup drive? If it's doing crazy stuff like this out of the blue, how can I trust it not to randomly crash? I think I overestimated Apple's competence. This should never happen. It actually made my SD cards defective.

MacBook Air :: It Won't Recognize Class 10 SD Card From Card Reader Or From Nikon D5100

Mar 2, 2012

I simply can't take any of my pictures off of my SD card. I've tried using the USB cable that came with the camera itself, as well as a USB card reader. iPhoto, and the laptop itself does not recognize the card, or that there is any device mounted at all. I've also tried checking "External Disks" in Finder Preferences, didn't seem to work.

IMac (Intel) :: OS X Mavericks (10.9.4) Memory Card Reader Not Detected

Sep 7, 2014

I have an iMac, early 2009 OS X 10.9.4. Up until a few months ago I didn't have a problem with my memory card reader. The computer no longer detects the memory card reader. There is no indication by the computer that the memory card read has been plugged in. I bought a new memory card reader (different brand). The computer does not detect the new memory card reader. I have tried rebooting the computer. That did not make a difference. I tried unplugging all the USB devices plugged into the computer. That did not work

MacBook Pro :: Won't Read SD Card But Will Read CF Card With The Same Card Reader?

Dec 26, 2010

As the title says, I have a card reader that works great with a CF card, but the MBP won't recognize an SD card. This is a new problem for me. I also have an express card adapter for SD that won't read the card, either. I have tried 4 different SD cards, and these exact cards have worked for me in the recent past (within the past 2 months). They work fine in the camera. I also tried connecting the camera via usb, which was unsuccessful. I tried blowing air on the cards and the reader. I cannot get the cards to be read on my wife's macbook. This makes no sense to me, as it worked fine the last time I tried. I find it hard to believe that all cards are corrupt, or the cable is the problem because it reads the CF card.

IMac :: Interference Between Airport Card / Wifi - Graphic Card

Apr 24, 2009

How certain are we that (physical?) interference between the airport card/wifi and the graphics card can be cured with a download, and not actual hardware fix/repair? I mean, I know technology is advancing rapidly, but I'm not sure I can believe that a download can solve the issue that the 4850s are experiencing.

OS X :: Card Reader Is Not Working?

Apr 5, 2010

I have a AMICROE 42-in-1 USB 2.0 Card Reader that I use to transfer pictures from my camera's memory stick (SanDisk Memory Stick PRO Duo 1.0 GB) to my mac. It always works but the last few times I have tried to use it it wont show up in iPhoto or anywhere else. I looked in disk utillity (which I think is the right place to look) but it is nowhere on my computer. What is wrong, what do I do? I also don't want to spend any money buying a new one or getting it fixed if it has a problem, but it is working coz the little blue light is coming on.

It has many different ports for different memory sticks and it works with some other cameras in different ports, I can't work out why it is doing this!

MacBook :: USB Card Reader Not Working?

Oct 10, 2010

I have a USB all in one card reader that doesn't seem to work when I connect it to my Macbook. It's an aluminium Macbook running snow leopard.

Ordinarily I would suspect that my �2.99 card reader is faulty and just buy a new one...however I also have an iMac, and it works perfectly with that.

Any ideas on what's wrong with my Macbook??

OS X :: Card Reader Not Responding After 10.6.5 Update

Dec 30, 2010

I have a MacBook Pro since september, which came with 10.6.3 installed. It worked perfect. Last Nov 20th I updated to 10.6.5 (from the automatic software update manager) and everything more or less ok, except for my SD Card slot which stopped reading any card.

I have checked it is not a card problem. I tried installing the 10.6.5Update Combo and it didn't work. I tried resetting the System Management Controller and nothing changed, nor any other method I've found on the web.

I would like to know if it is known a concrete fixing of this issue; otherwise I think the best thing to do is to downgrade back to 10.6.3, which was the originally installed Snow Leopard version.

MacBook Pro :: All In One ExpressCard / 34 Card Reader?

Aug 4, 2009

I used to do DSLR photography with CF, but fell out of love with it and sold it, so now it's back to regular old SD for my point and shoot. I'm looking for a card reader that obviously supports SD, but I'd like some type of all-in-one so I can throw most anything at it. I'd also like it to be flush with the computer when inserted.

OS X :: SD Card Reader No Longer Recognized?

Feb 14, 2010

I recently bought an SD card and reader for my Macbook Pro. It was working fine for a good month or so but as I was copying something to the card today, an error message appeared which said something about not having the right privilege to copy the content over to the SD card. The SD card was unmounted (if that's the word you'd use) automatically. When I tried plugging it back in to try again, nothing happened. I've tried plugging it into my PC but it says the device I've plugged in is not recognisable. The SD card reader has a red light that goes on when you plug it in which doesn't switch on anymore.

I've put the SD card itself into my TV as I was copying some video onto it. 15 minutes of the video has been copied and it's playable which to me suggests that the SD card itself is fine? Is there any way I can get it working again? I don't really understand what's happened.

I am ready to purchase a MBA; however, I am in the Army and have to use the Army ID card (CAC card) to access certain areas on Army websites.  Does anyone know if the software required to run the CAC card reader can run on the MBA OS or will I have to use Boot Camp or some other software to run MS Windows vista or 7?

Intel Mac :: Recommend A CF Card Reader For It?

May 21, 2012

I have a iMac (Intel) desktop and also a Windows based PC. I use the newer Mac to process JPEG photos in Lightroom 3, but here's the catch: most of the time my older Sandisk ImageMate 8-in-1 CF reader does not show up in LR3 (I connect the USB plug directly to the back of the Mac's USB slot). It works just fine with the PC. So it may be a hardware problem and I am willing to invest in a new Mac compatible card reader. My Mac runs on OS X (Lion).

MacBook Pro :: USB And SD Card Reader Not Working?

May 29, 2012

My wife's Mac Book Pro (around 18 months old) gets an error message when she hooks up our Canon camera.  It says the USB is drawing to much power and has been disabled. She has downloaded 1000's of pictures without problems and now that message pops up.  And she doesn't have anything extra plugged in since the last downlaod around a week ago. Also the SD card reader isn't working. When the card is plugged in nothing happens and we can't find the card in iphoto. So now she has no way to get the pictures on iphoto. It's not the cord or the card because I can download them without any problem on my Windows computer.

MacBook Pro :: Does Not Recognize SD Card Reader

Sep 7, 2014

Lately, my macbook pro has not been recognizing my SD card reader. SD cards do not mount, and it looks like the computer is not recognizing the SD card reader at all (When I check About This Mac -> More Info -> System Report -> USB, the card reader does not show up). I've never had a problem before, in the ~3 years I've had this Macbook. I'm running Maverick.

Hardware :: Expresscard 34 - SDHC Card Reader

Aug 20, 2009

I really need to get hold of an Expresscard 34 - SDHC Card Reader for my MacBook Pro 15" late 2008. My Mid 2009 MBP has it all built in which is great. I have had a look on the net and they seem scarce. All of my SD cards are over 2GB in size, mostly 8GB so I need it to support SDHC. I would also love it to fit flush with the MBP and maybe be grey in colour! Please can someone help and let me know what model to 'google'

Mac Pro :: Will Read Thumb Drive But Not CF Card Reader

Feb 19, 2012

I just erased everything off my Mac Pro and reconfigured everything (as new). I installed all my programs, primarily Aperture3 and Photoshop CS5 (using Leopard).I had no problem uploaded some photos into Aperture3 from a thumb drive using the USB port, butwhen I tried to upload photos from my card reader the MacPro does not recognize the card reader using the same USB port. I figured the problem was a bad card reader.

I tested it on my PC and it recognized the card reader and uploaded all the photos. Also, the card reader's green light turns on when attached to the MacPro, as if it is working and connected but it does not register in Finder or desktop to indicate that the card reader is installed.I even tried to upload directly from my Canon 7D and it also did NOT recognize the camera.Why would the MacPro recognize the thumb drive on the same USB port and not the card reader or the camera?

MacBook Pro :: SD Card Reader Not Working In Windows

Feb 20, 2012

So here's a weird one. I have a Macbook Pro 15" (MacBookPro 8,2). SD card reader reads my SD cards just fine on the OSX side of things. I have Windows 7 x64 installed as well, with BootCamp 4.0 drivers installed, everything is fine (including device manager saying that SD card reader drivers are perfectly fine), except the card reader absolutely refuses to read any SD cards. I've tried several of them. The laptop isn't even aware that a card has been inserted. Anyone have any ideas? I'm stumped (which rarely happens, give the fact that I am an IT consultant by day). I've reinstalled the drivers for the SD card several times.

Intel Mac :: Ejecting A Usb Camera Card Reader?

Mar 18, 2012

How do I remove a usb cable for a media card reader after I have downloaded photos? I get the "you just screwed up your card dummy" notice.I finally figuered out how to eject a cd/dvd. The Mac only takes small media cards and I have to use a card reader to load photos onto my Mac from a SanDisk CompactFlash camera card.With the cd/dvd's I can go to Finder and hit "eject" and it will. With the usb for the card reader I have to pull it out, of course it will not eject like a cd.
