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.

The Card Reader stops with Windows Error Code 43 at times (Unknown USB Device (Link in Compliance Mode)). I can disable the device, re-enable it and it works properly after that. I will post some screen shots next time it happens. You may want to check under Device Manager -> Universal Serial Bus Controllers section and check if you have an entry with a yellow triangle and exclamation mark when this happens.

Ok, but that looks like a driver bug too: The card reader should not stop working... It might be ok for you to restart the device. But for me it is not an appropriate behaviour of a storage/disk device which i want to be reliable.


In addition your workaround doesn't help me: The device disappears in my device manager/error code 45. So I am not able to re-enable it in the way you suggested.

Since we not heading towards a solution I think we should stop here. Thank you for your help!

That's great!!! Thank you for submitting the bug.

I am also a Windows user on the MacBook Pro and this issue is really annoying, hope they solve it anytime soon. I think that the issue is related to the USB hub where everything is connected, because I have also put the computer to sleep with a USB Hard Drive and after wakeup it didn't recognise it either.

I have tried this but it does not work for me either. My conversation will Apple technical support has been absolutely useless. They claim that this is a Windows issue not an Apple driver issue. Obviously Microsoft/Windows technical support states that they don't support windows on a MacBook. I have reached a point now that the SD drive does not show up even when the system is rebooted or cold started. Drive works fine on OS X side. Hopefully Apple will address this soon.

Well, to my mind it is Apple who should at least take some action in this case. I reckon a somewhat big part of their sales is based on compatibility with Windows, in my case I bought it solely because of its supposed "compatibility" as I had no interest whatsoever on OS X. To my mind, having the SD card disconnecting, together with an issue that we had with the efi and windows and the trackpad's lack of functionality is not what I would call "total compatibility".


The EFI issue was solved, the trackpad is easily solvable by using trackpad++ or by configuring the Apple driver with a bit of care, but what about the SD card? It does not happen on my Surface Pro 2, so don't say "Windows' to blame" because it is obvious that it does not always happen, and the only customisation made to the os is apple drivers.

This may temporarily provide some relief. Get VirtualBox (it is free). Import Bootcamp as a VM. Connect the SD Card to the host OS which is OS X and the card works properly in it. This will allow the VM to see the device as long as the host can see it. You can also allow device passthrough to the Guest (Windows) from the Host (OS X).

I'm doing the same with parallels. With parallels you actually can boot from the bootcamp partition so you can choose if you want to use OS X with windows as a virtual machine or you want to boot into windows, both of them being the exact same installation of windows with the same data and programs. Do you know if you can do this in VirtualBox?


Apart from that, you're right in that this is a "workaround" but you don't get the full performance of the machine on Windows. Sure it works, and it is absolutely right to do it, but I hope Apple comes up with a solution soon 🙂

Well, the SD card is the only media that can be permanently attached (e.g. a Nifty Minidrive). Even though Apple and MS are rivals, that makes no excuse for Apple disregarding an annoying and serious issue with the software they provide. I suppose I am not the only one who uses the MBP for Windows. So I expect them to give a solution...

Guys,


I'm having the same issue on my lovable but irritating at times MacBook Pro Retina 15" mid 2014 running Windows 7 Professional 64-bit!

I have no solution to offer other than to rant off at Apple for not supporting us!


I was sold on the MacBook Pro when I was looking for a new powerful laptop with a beautiful screen but couldn't find one on the PC side. I kept hovering over to the Mac isle at the electronic store and I finally went for it! In this day and age, why can't we have the best of both worlds? I don't get why manufacturers won't get off their a**es and develope an awesome laptop like Samsung has with the smart-phone industry!


After having trouble with the bluetooth, touch-pad device, and now the SD Card, let alone the proprietary SSD drive, I'm starting to realize that maybe Apple doesn't want my business because I chose Windows over iOS, which is insane! After all, isn't Apple all about the bottom line? If there is enough of us Windows on Mac users who complain, won't they listen?


Unless I can a resolution to this soon, I'll probably be selling my MacBook Pro and going back to a PC Laptop and never buying an Apple product again! It's your call, Apple!
