SD Card Slot Disappears After Sleep (Gone Until Reboot)

I love my new Macbook Air 2013. Its speedy Core i7 and lightening-fast 256GB SSD make for quite a wonderful experience in Windows 7, too. But I have a problem that is proving to be quite the frustrating little niggle, and I just can't sort it out. So I've turned to you guys for help.

Here's the thing: the SD Card (the slot, the device, the card, the folder, the drive, everything) just vanishes after the MBA wakes up from sleep. I've tried it with various cards with different filesystems (FAT32, NTFS, EXFAT) and capacities (32GB, 64GB, 128GB) -- always the same. I've reinstalled Windows 7 Pro x64 multiple times using up-to-date boot camp assistant and Apple Support Drivers.

The card works fine. Until, of course, the computer goes to sleep. When it awakens, the card is gone -- even from the device manager -- until the computer is rebooted. That's right, plugging the card (or any other card) into and out of the slot doens't fix it. Neither does resetting the NVRAM or SMC. Neither does adding an event to the Task Scheduler to disable the device prior to sleep and re-enable it on wake (it doesn't re-enable, the entire device vanishes).

Here are some more details:

- Putting the card in for the first time while the computer is asleep is okay -- the card appears when the computer is awakened. But putting it back to sleep afterwards causes the same behavior -- the card and reader disappear until reboot.

- The computer can go to sleep and wake up many times without a card inserted without the device disappearing. I can put a card in and have it recognized propertly after any number of card-free sleep-wake cycles. But the moment the computer sleeps with card inside, the reader disappears until next reboot, no matter what.

- This behavior does not occur in OSX to my knowledge (although OSX handles both mounting AND sleep states VERY differently than Windows, so I can't directly compare).

I have tried everything short of scripting a reset of the root USB hub (a highly unrecommended procedure that can disable the keyboard/mouse/etc). I've even tried new USB hub drivers (intel 8.10) to no avail.

Anyone have the same issue? Does this work for you? Does anyone have a copy of older SD card drivers (maybe the latest ones are screwy?). Thanks

MacBook Air (13-inch Mid 2013), Windows 7, OSX 10.8.5 too.

Bump. Anybody?

Am I the only one whose SD cards disappear after waking from sleep in boot camp?

I have the same problem too 😟. By the way removing the usb root hub doesnt make the sdcard come back. I have tried by remote accessing it with team viewer. However, i noticed that rarely it will be detected again after 10 minutes, this only happend twice.... when it comes back alive event logger says (below). Is this relavent?

I am having this exact same problem and I can repeat it on several MacBook Airs that we have in my lab. It doesn't matter if its Windows 7 or 8, it always happens. It does not matter if the card is in or not, the results are the same, when the computer goes to sleep mode, the SD card slot is not available anymore. This is defeintely a bug in the Apple driver. I hope more people see this post and confirm their results so that this situation can receive a fix.

I'm having the same issue - reboot is the only way I can bring the SD slot back. I've tried changing the driver from "Apple SD Card" to the native "USB Mass Storage" devive, but no change.

Hi,

I have the same issue. Tried different cards with same results meaning disappearing after sleep.

Installed latest Bootcamp drivers which didn't help either.

What I found out yesterday was the card appears again when you hibernate the macbook air after sleep and when it comes out of hibernation the sd card is present.

hreede --

I am not sure I understand your grammar here. Do you mean that hibernation works and sleep does not?

ok, will try to clarify.

SD card is indeed disappearing when macbook is returning from sleep status.

SD card is still there when macbook is returning from hibernation status.

SD card is disappeared after returning from sleep but when I put it into hibernation then, the sd card appears again when it is returning from hibernation. Point is that you don't have to reboot but can use hibernation to get it back.

Of course still not how it should work, but for the time being an alternative for complete reboot.

Tthis still leaves the question whether this behaviour is a driver issue or something else.

I have the exact same problem.

Late 2013 13" RMBP running Windows 7 64-bit.

Just tried the hibernation trick and that didn't work for me.

It was working just fine for me under Bootcamp 5.0.5033 but after upgrading to 5.1.5621 I've run into the same problem as the rest of you.

Mar 26, 2014 11:28 AM in response to TheFiZi

Be careful with the hibernation. I tried it and it did work, then I left my computer in hibernation for a few days. When I tried to wake it up it gave me endless blue screens of death. The boot sector got screwed and I was unable to recover - resulted in a format of my windows partition which was very annoying. I have often avoided using hibernation in the past, but this has confiremed that hibernation is to be avoided at all costs on a machine that you can't adjust bios settings.

The SD card slot issue remains. We wait for apple to release an updated driver.

Same problem 13" RMBP late 2013. The SD reader controller is BCM57xxx - some IC from Broadcom.

Hybernate/dehybernate helps to me so far. But You never expect such glitch from the 2kUSD+ notebook...

Hope Apple and Broadcom will solve the issue soon.

Jun 17, 2014 4:37 PM in response to Gabe-A

I am experiencing this as well on a late 2013 rMBP. Going into and out of hibernation seems to recover it, as some have found out for themselves.

Sep 8, 2014 11:16 AM in response to Gabe-A

hy.. i do have/had the same problem on my MBAir2013late with Arch-Linux..

the problem was, that i could not unload the driver "xhci_hcd" (USB_Driver) manually, since it was loaded in the kernel... i recompiled my kernel without this driver being load automatically (set on manual).. then i was able to unload the driver "xhci_hcd" before going to sleep-mode by a script and loaded it again when the mbair woke up..

now my sd-card is here after suspend, since the drivers are loaded everytime, when mbair wakes up...

I dont know if this can help for people using windows...

Sep 13, 2014 11:18 PM in response to lordvampire

Yeah, I have the same problem with my brand new MBP!!! Apple really needs to fix this!!!!!

Jan 5, 2015 3:44 PM in response to Gabe-A

I've had my sd card disappear as well after resume from sleep. appeared only after reboot.

though eventually after 4 times it happened , the card wouldn't appear at all on any computer until I've used

sandisk reformatter . that helped to make it usable again but erased all previous data (data recovering seems impossible too)

is this gonna keep happening ? where is apple support on that ?

can i even put new data on my SDcard without fear ill have to reformat and loose it in the future ?!?

seriously , this should be an easy fix

issue was on maverick and now on Yosemite macbook pro retina (late 2014)
