Why does my SD Card power down on it's own?

[MRode2]

 Friday November 29 14:07:08 MT

I own a quad Celeron NUC = NUC6CAYH. I came with a

Realtek PCIE CardReader 

Manufacturer    Realtek Semiconductor Corp.

Status  OK

Driver Provider Realtek Semiconductor Corp.

Driver Version  10.0.15063.29094

Driver Date     5/3/2017

Device Id       PCI\VEN_10EC&DEV_5229&SUBSYS_20678086&REV_0

I purchased a

SanDisk Ultra 200GB microSDXC UHS-I card with Adapter - 100MB/s U1 A1 - SDSQUAR-200G-GN6MA

I formatted it with NTFS and copied files to it. The CardReader reads and writes without any issues. However, after a few hours..maybe 4 to six... it turns off and becomes unavailable. If I pull it out and plug it back in the card reader drive reappears. If I reboot it does not reappear. I have to physically pull it out and put it back in every time I want to use it. I am running windows 10 PRO. This is a media box plugged into my TV so I have disabled power save completely....in the OS and I checked the BIOS. I have had many laptops, and have three now, all with cardr eaders and have never had one power down seemingly on it is own. This seems like more of a driver issue then a power issue but there have been no driver or OS updates that resolved it.

Did Intel design it to behave this way? Is anyone else having this issue? Thanks.

Hello MRode2,

Thank you for the information.

Can you please try to perform a clean Realtek* Card Reader Driver installation?

• Download the latest driver from our website: Realtek* Card Reader Driver for NUC6CAY
• Disconnect the computer from the internet connection.
• Open the device manager.
• Click on Memory technology devices to expand it --> click on Realtek* PCI-E CardReader.
• Select the tab that says ''Driver''.
• Click uninstall driver.
• Restart the Intel® NUC Kit NUC6CAYH.
• Run the driver previously downloaded.

Note: Can you please check if by any chance you see on device manager a power setting option for Realtek* PCI-E CardReader? please let me know if you see it.

Hi MRode2,

When the SD card stops responding, can you check the Windows Device Manager?

Please go to >Storage Controller>BayHub Tech Integrated MMC/SD controller. Is it still there? If yes, can you please check properties and look for any issue?

What happens if you plug-in a different SD Card? Is it recognized?

I haven't solved the issue. I did discover that while the SD card is not dismounting while the OS is running. It is disappearing on every reboot. In order to get it back I have to physically remove and replace it. I was confused on this point because long ago had written a script to reboot the computer at 4AM and I had forgotten that it was running. I use it for my TV and it runs 24/7 so once a day I do a fresh reboot. When the SD card is mounted it works perfectly until it reboots and then upon start up it does not auto mount. I must physically take the card out and put it back it for it to mount.

I have tried other SD cards and have the same problem.

I have checked Windows Power settings and turned all power saving off.

I have removed and SD card driver and then rebooted and reinstalled the driver.

I have never tweaked the BIOS, but just to make sure I re-set the NUC BIOS to defaults.

Is the SD card intended to dismount and not auto remount on a reboot.?... if so I have not seen this before on any device. A SD drive should operate like another driver controller.

I have another issue that has come up in the last couple of days that perhaps you will be able to help me with. The Intel tray app informed me that there was a new Graphic update. I ran the scan, clicked download, click install. When it asked to reboot I did so. However, it just keeps telling me there is a new graphic driver and Scan shows

Intel Graphics - Windows� 10 DCH Drivers for Intel NUCLatest version: x.x.x.7529Installed Version: x.x.x.7262

So it appears I have the latest version but there is something wrong with the scanner and the tray app.

Hi MRode2,

Thank you for your response.

Our apologies for the delay replying back to the thread, we were working on your case by trying to test this behavior in our end, we also used a PassMark rebooter to create a rebooting cycle and never had any issue, the card was always recognized and data accessible.

This might be related to the OS, our recommendation is to contact Microsoft support.

I tried a lot of different ways to fix this without result. Bios changes, OS power changes, remove, and reinstall the driver but nothing worked. Then one day the Intel update utility informed me I had driver updates which turned out to be a graphic driver. I installed the update, and instantly the SD card started working normally.

Hello MRode2,

Thank you for your answer.

I am glad to know that after the update the SD card is working fine.

Hopefully, this will help other peers.
