SD and SDHC cards will not mount after updates to OSX

Do you have the same problem when logged in to a different user account?

My software update says I am up to date, but my macbook pro, macbook and macbook air will not mount sdhc cards greater than 1 gb in size, either with a usb reader or an expresscard reader. CF cards of any size are no problem.

Actually seems my card readers were too old, I tried a kensington part # fcr-hs219/1 and all the cards were visible

I've been able to mount CF and SD cards of any size using a generic multi format reader on my Powerbook G4 but on my MacBook it does not mount the card/s if it has a capacity of over 1GB using the card reader.

I managed to get my card (Verbatim SDHC Premium 16GB 133Xread 60Xwrite) in the canon G7 picked up only through iPhoto. Nothing else worked.

Hope this helps

Kingston 512MB SD cards do not mount on my 1 month old MacBook Pro with the latest software. I tested two of those, one I just bought in a shop.

I need to use these cards, because cards >1Gb do not work properly in my iLiad eReader according to Mobileread.com.

Other cards do mount. I have an old 8Mb JVC or a 2Gb.

System Profiler says:

Kingston:
Capacity: 477,9 MB
Available: 476,8 MB
Writable: Yes
File System: MS-DOS FAT16
BSD Name: disk1s1
Mount Point: /Volumes/Kingston

The contents of the card are visible when I use Terminal to go to /Volumes/Kingston

How to proceed from here?

TIA!

Same problem, just happened 8 days ago! Using Mac OS 10.5.8(up to date). From one night reading my SD card and having everything fine to the next morning suddenly not reading it:(

I tested a few SD cards, it reads some, others do not register and others ask to initialize.

*Noticed it is the SDHC and HD ones, the low quality simple ones read fine.*

High quality SD cards and SD reader work fine on PC 😟

Also, I doubt this is a factor my higher quality SD cards are 4GB and 8GB while my low quality cards are 2GB.

Reset SMC does not seem to help. May need to re-install operating system but do not know if that will help as it seems to be an update problem. Please let me know if you noticed the same problem, here is to hoping this is fixed SOON :}

Same problem here after updating to 10.5.8. The SDHC cards have been working perfectly for 5 months with a card reader and this evening they all just stopped working.

I managed to get some images off using Image Capture and connecting the camera via a USB cable, but the cards (one Sandisk 8GB and one Transcend 4GB SDHC) will no longer mount on the desktop.

Was a solution ever found to this problem?

I'm having the same problem mounting a leica m8 using 8GB sdhc class 4 card. I heard this camera did not initially support sdhc, so it might be an issue. I was able to mount my dlux4 just fine using the same card. I'm really confused, not knowing if the problem is with my camera or the OS. iPhoto can detect the camera but i can't access my DNG files.

This still appears to be an issue. I have a card reader that I was using with my laptop and desktop and now it works on neither. What is the fix??

As per an earlier post in this thread, I looked for the OSX 10.5.8 Combo Updater and installed it. Though my 10.5.8 was current, the Combo Updater seems to have repaired the USB connection issue. I would recommend this to attempt to solve the issue, but be sure to get the combo updater for your system, and BACKUP before installing.
