Windows 10: Windows 10 2004 makes SDXC card reader pause and stutter

My SDXC card reader was working perfectly. I would read PDFs on it, play music, and watch videos on it. I'm running a Dell Latitude system.


I waited three months for Microsoft to work the kinks out of the Spring 2020 Windows 10 upgrade version 2004. Then I upgraded to v2004 on August 24, 2020. Now after upgrading my SDXC card reader pauses all the time.

• When I am browsing via Windows Explorer, when I open some folders everything pauses for a second or two. Similar behavior has always happened on a connected USB spinning hard drive which would go into sleep mode. But this is an SD card, and my reader has never exhibited this behavior.
• Sometimes when I am playing an MP3 audio file from the SD card reader, the song will just pause for a second or twoduring playback.
  
• Sometimes when I am watching a video from the SD card reader, the video will pauseduring playback. Sometimes but not always the audio will continue, but then the video will race to catch up. I imagine this is because the data pauses just like with audio playback and audio and video are buffered differently.

Again this has worked just fine for years through many Windows 10 updates. But version 2004 screwed up access to my SD card reader. It's like it turned on some sort of sleep functionality that continually appears, even after a few seconds, and even if the drive is being used!


In Device Manager I could find no "sleep" or power management setting for the SDXC card reader.


Some of the USB controllers marked as "USB Mass Storage Device" have a power management setting "Allow the computer to turn off this device to save power", but it is not clear to me which of the two "USB Mass Storage Device", if either, corresponds to my SDXC card.


Note also that in Device Manager my SDXC card under the "Events" tab shows that on the day I upgraded to v2004, the device was "migrated":

• 8/24/2020 [time]: Device migrated
• 8/24/2020 [time]: Device configured disk.inf
• 8/24/2020 [time]: Device started disk

Why was this SDXC drive "migrated" to begin with, and what does this mean? Maybe I need to reinstall the Dell drivers and override the Microsoft ones?


No, I'm not going to reinstall Windows 10, so don't even think of suggesting that.

Trying to install apps onto an sdxc card

Hi John,

Conflicts with the SDXC card file system is one of the possible reasons why you are unable to download a file or install an application to your SDXC card. For us to assist you better, kindly answer the questions below:

• Have you made any changes to your computer prior to this issue?
• What troubleshooting steps have you done so far?
• Which version and OS build number of Windows 10 is currently installed? To check, press the Windows key, type winver, and press the Enter key.
• What is the make and model of your device?
• Do you received any error messages?
• Have you tried using a different SDXC card, and check if you will be able to experience the same issue?
• Have you tried to copy/paste a file from your C: drive to your SDXC card?
• Have you tried inserting your SDXC card to a different device?
• What is the file system of your SDXC card?

Meanwhile, I would suggest that you try to reformat your SDXC card to a NTFS file system and check if it helps.

We'll be looking forward to your reply.

 

SDXC card does not mount in Windows 10

64 gig SDXC (note: not SDHC) card does not mount for reading or writing in Windows 10. This worked on my system's SD card reader under Windows 7. The external reader is recognized on the USB bus but the media is not mounted as a disk.

{ANSWERED} Requires an SDXC-compatible card reader. My external USB card reader does not support SDXC.

{NEW QUESTION!} The internal card reader on my system -- which does support SDXC on Windows 7 -- is not recognized by Windows 10. That's why I was messing around with the external reader. Guess I need to hunt down a working driver for the internal reader
(10-in-1 USB 3/multiformat card reader, fits in the floppy disc bay)

 

Stuttering video on Nokia 810 (SDXC card)

When recording videos onto my Class 10 Sandisk ultra memory card, the video stutters and pauses as if the camera is dropping frames. recording anything which moves seems to make the pausing worse. Even short 5-10 second videos suffer from this problem.

When recording to the phone internal memory this does not happen. However the Sandisk Ultra is one of the faster memory cards available so there is no reason I should not be able to record videos straight to the card without this problem.

Has anyone else had this problem? Is there a solution?
