My macbook won't read my sd card.

My sd card has worked in my computer before, but today it decided not to work. I've tried reformating it on my camera, inserting the sd card into the slot faster than usual, but my computer acts like nothing is going on. Help?

Remove sd card and insert and remove it multiple times from the card slot.... also try cleaning the contacts.... See what happens it worked for me... Hope this helps...

Won't read my memory card

Hello! My macbook pro won't read my memory card (transcend) anymore. It used to work fine but I don't know why just recently it won't. I've tried the little lock and unlock option on the card but still nothing.
Help?

Macbook won't read disks!

my macbook won't read disks, it justs ejects it immediately after insertion. It's a software based issue because I have my hard drive partitioned with linux mint, and on the linux os all disks work with no problems. It might be a red flag but I ran an executable file earlier labeled nocd. On the other hand though acouple days ago I inserted a disk for an apple tech utility and it just ejected the disk immediately as well which was the first time this happened, but i didnt think anything of it because I assumed the utility just wasn't compatible with my computer. I work at a help desk for a university so i thought maybe because it was not a university owned computer, I don't know, i'm not sure what my logic was there. but reguardless what i've tried was to kill backround processes involved with disk mounting and letting them respawn, there don't seem to be any unusual processes running on my system over all, after I killed those processes my home directory couldn't be located, I'm not sure if what I killed had anything to do with it, and don't really believe it did. I know the superdrive is not dirty or anything of that sort seeing as it read the disk fine in linuxmint. Any suggestion? thanks in advance for any replies

Macbook won't read card from Canon G10 in USB port

I can't copy Canon G10 RAW files from an SD card via a USB card reader onto an aluminum MacBook. I tried using Adobe Lightroom (the way I usually do this on another machine) to import the files but it couldn't recognize them. I tried to copy the files into a folder on the Desktop but I got a insufficient priveleges message. It seemed to copy the file names but tnot the files. When I tried to remove the card I got a "File is in use and can't be removed" message.
The card reader and the card work fine on a 24"Intel iMac.
Another USB card works fine in the card reader on the MacBook, too.
I'm puzzled.

Some added info, i CAN boot the bricked machine into Safe mode, but at reboot I get stuck in the same cycle again.
Oh, and in SafeBoot, the Macbook still tells me that no Airport card is installed, even though I know it does (and it's not knocked loose or anything).....

MBP won't read my SD card?

So here's the issue:
My MacBook Pro won't read my 4GB SD card from my camera. I was able to transfer all of my images earlier this afternoon but now it plainly won't show up. I checked Finder, I checked Disk Utility, and nothing. The Nikon software doesn't recognize it either. It's not like I have a whole boatload of photos to transfer (I only have four pics to transfer). Earlier, I installed the software after I ejected the card, but did not put it back in afterwards. Could it have something to do w/ the software I just downloaded?

If you are using a DSLR camera, like for example a Canon 60D, there may be an option to use a "Low-Level Formatting" on the card. This should make it writable when putting it into the computer.
To test this (and confirm it works) I did the following:
Hardware Used:
Canon 60D camera body
Sandisk 32GB SDHC Extreme Card
Macbook Pro 15" (mid 2010 model) with built-in SD card slot.
Steps:
Place SDHC card into camera (SD card may work as well). Navigate through menu until you arrive at settings that allow the camera to format the card. There may be an option to format it "low-level", which you would then select.
-Note that all files on card will be erased permanently.-
After the camera formats, eject the card from the camera, and place inside the built-in SD slot on the Macbook.
The card should automatically mount, containing both read and write priviledges.
Hope that helps.

Won't read the SD Card after going in for repairs

HELP - my 8520 curve won't read it's SD card? i know it's definately not the card as my wife just got a new BB also and it came with a brand new card that can't be read either. Thought i could live with it............ but can't. You can't have any music, video content etc............ My first blackberry died in a pint of guiness (don't ask), i took the sd card out before the insurance claim and had my fingers crossed that it would have survived the black death, but when my new replacement BB came it couldn't read the card.......... which i thought was down to the black stuff - initially.
However since then i've tried different cards leaving me to believe i may still have the data on the original and that the phone or card reader is cream-crackered? any clues?........ thanks in advance.

I've read on some forums this could be a card formatting issue, anyone got any thoughts on that?

MacBook Pro won't read the sdxc card from Panasonic GH2

I've got a MacBook Pro running 10.5.8. Just took my first pictures/video with the GH2 using a Lexar 64GB SDXC card. When plugging in the USB cable that came witht the camera I got - "The disk you inserted was not recognized by this computer". Does anyone out there have the GH2 that has experienced this problem? Solution? I've written to Lexar but so far they've been no help. I know the file system for this card is FAT32 which is a PC format. I know this card will work with the Mac...but how is it accomplished?

Your easiest & cheapest way to transfer the camera pictures is to buy (about $10 - $20) a USB memory card reader. Just plug your camera's memory card into it & copy the pic files to your Mac. Quicker & easier than interfacing the camera for pic transfer.

MacBook Pro won't read Sandisk SDHC cards since Lion 10.7.1 update

Hi all, just wondering if anyone else has had this problem. I know there are dozens of posts about SD cards not working with MacBook pros, but mine seems to have started when I installed the latest Lion update.
I have a high-end 13" early 2011 MBP and the cards I'm having trouble with are all Sandisk 4GB SDHC. Two are 'Extreme III's" and one is an Extreme II. The card reader is showing up in System Profiler, and a really old 2GB Sandisk card gets read fine, so there doesn't seem to be anything wrong with the MBP hardware.
Similarly, I can read the cards fine via a USB adapter, so it's not the cards that are causing the problem.
I had successfully imported photos from the cards before upgrading to Lion, and also before installing the 10.7.1 update. So, it looks like the problem may be linked with the update, but this is purely an educated guess.
I've tried resetting the SMC to no avail.
Has anyone else experienced something like this?

I've got the same problem. I've got a late 2010 MacBook Pro unibody running Mac OS 10.7.1 on it. I installed the 10.7.1 updated most likely on 8/17/11 the day after it was released by Apple. Since then I was able to read SDHC cards as I shot a number of photos and videos to my cards and they worked fine.
I'm not sure what has changed since then, it wasn't as simple as the 10.7.1 update then it didn't work. This is the problem I'm having below, just started to experience this on 9/2/11. I tested with two 32GB SDHC cards, one 16GB SDHC card and one 2GB SD card. All cards were manufactured by Transcend.
FAIL:
* SDHC cards (16GB and 32GB) will not mount and isn't recognized by the MBP via the built-in SD card slot
* SDHC cards (16GB and 32GB) will not mount and isn't recognized by the MBP via SanDisk 2.0 card reader connected via a short USB cable.
* If I put any SDHC card into a SanDisk USB 2.0 reader that is connected to my USB hub (I gave it a try in case there was a power problem with the MBP USB system) the card is not recognized either.
* Even Disk Utility will not see the card when inserted via built-in card slot or a reader.
SUCCESS:
* SD cards (2GB) mount fine when inserted either in the built-in SD card slot or via my SanDisk USB 2.0 reader.
* If I leave the SDHC card in my camera (Canon 60D) and connect the camera to my MBP via USB I can import the images via Aperture.
* If I put the SDHC card into the memory card slot reader of my HP inkjet printer (it has multiple card slots for different types) the card will mount normally like it is supposed to via the two failed methods above.
I'm also sending this info to Apple but wanted to post here since there are three inconvenient work-arounds.

PCMCIA Card Reader for MacBook or MacBook Pro to Read Panasonic P2 Cards

Is there a MacBook or MacBook Pro that comes with a PCMCIA slot that will accept the new Panasonic P2 cards that are used to capture the DVCProHD format? If not, is there an alternative to the Panasonic reader that uses an USB connection to send the information to the computer. Currently, the only way I can import the material is via the camera. Thanks for any help.
PPC Dual G5 2GHz Mac OS X (10.4.7)

Spot On!
I am completely sold on the technology and its future. I recently read an article on a future codec that will be available for the camera and card that will use the H.264 scheme in the compression. This will double the amount of content that a card will hold. In other words, from 8 gigs = 8 minutes to 8 gigs = 16 minutes. This will come in the form of a downloadable update for the camera and cards. REALLY COOL!!! You won't have to buy a new camera to take advantage of the improved codec.
As far as color reproduction, HDV cannot come close. If you look at the technical aspects of DVCPro HD vs. HDV, it's a "No Brainer."
Happy Shooting!

Macbook won't read my EZquest firewire external hard drive.

I need this hard drive to back up stuff for school. I only have one firewire port in my Macbook. It's not reading it when I plug it in though. Not even on disk utility. What am I doing wrong? Thanks.

I have a similar problem. Bought an external drive to store music and pictures, followed the instructions on several threads here on how to transfer these from my D drive (the back up drive on the computer itself) to the L drive (the Buffalo Linkstation); changed the location of the library to the correct address where all the music files are (I can see them there) having consolidated them there. It could not find any of them unless I individually located them (there are over 9000 tracks so I have not got time to do that). I changed the location back to the original and it found them again. Next I tried following the thread on the .itl file - using shift and selecting the library on the L drive, but it only found 300 tracks, some bought, some transferred, some full albums, some only part of the album, an apparently random selection. I tried going back to the original .itl file and the same happened - it only found the same small selection of tracks. I know the files are still there - I can see them, but I have no idea how to connect itunes to them. Please help!

MacBook Won't Read M-Audio e49

Hey,
Just trying to plug an M-Audio Keystation e49 into my Macbook Pro (retina) and it's not reading it at all. I've tried going into Audi MIDI Setup and still nothing. It's not the keyboard or the cable as I just tried them on my iMac.
Any suggestions?
Thanks

My macbook won't read the snow leopard disk but my macbook pro does...why?

For better or worse I ran a clean install of the original MacBook OS for an early 2008. It had been running Lion over the years it had never been wiped and reinstalled. In any case, I successfully reinstalled 10.5.2 with the start up disks that came with the machine when we purchased it. (That showed me the drive was operational.) I then attempted to install Snow Leopard with the install disk we've kept and the drive rejected it; however the MacBook Pro's drive did not reject it. (That showed me the disk is operational as well.)
Is the problem as simple as having to update Leopard to the max before the drive will accept the Snow Leopard disk?

Zap the PRAM and Reset the SMC; then, try again. BTW, does the optical drive show up in Apple menu item->About this Mac->More info?

Computer won't read my SD cards

I am trying to upload pictures and videos from my SD Card and also from a PRO Duo SD Card, and my computer doesn't seem to be reading them. I have done this before without any issues. Please help, these are wedding photos and the bride and groom are counting on me.
This question was solved.
View Solution.

Some of the new SD cards are not playing well with older hardware. since no mention of model number for the computer, I would suggest getting a new card reader (USB driven) that can read the newer SD card format. The easiest method, you could connect the camera with the supplied USB cable, that way the camera becomes the card reader.
