    I'm having the same problem here, noway to fix it :(
    My Z83-4 was fully reinstalled last May with the Creator Update and the drivers provided in the Win 10 drivers thread. All worked fine at the beginning, including the sd card formatted ntfs and configured as a subdirectory "c:\users\mydata\" (drive letter removed). After some time the sd card began to disappear and appear again after some time without a specific event to cause it. Now disappeared completely and I cannot manage to see it again.
    The sd card (a 64Gb C10 U3 manufactured by toshiba) keep working fine on other computers.
    I can exclude the card reader and the rest of my z83-4 is broken in any way and I can say it is definitely an issue with the driver.

    Is it possible that someone from Minix tell us how to manage this issue or if a fix for this issue is under preparation and when will be released?

    Can you please describe the steps to install the w8.1 driver. I tried to install, but still my ntfs Card with the users file on IT is not detectable....also tried the Fernando USB 3 drivers, without succes.

    I found that my SD card seems to stay active, but USB storage drops after power save kicks in. On system wake up, the USB thumb drive is not present and has to be unplugged and plugged back in Could this be related?

    I am having similar problems! I cannot transfer large (~5Gb) files reliably to my 64Gb SD card. It often works the first time at 25Mb/s but soon drops to zero and then spends a long time being erratic and finally times out and stops.

    BIOS 5.011 03/07/2017, W10 PRO v1709

    I also cannot get WiFi to work after upgrade. The Broadcom 802.11 fails to start. I have followed all of Ken's advice on file placement and reinstalled several times.

    I am stuck!

    Same trouble since one week.

    I just got my Z83-4 Pro from AliExpress. I booted an Ubuntu installer (from a USB stick), where it doesn't see the SD card. Then I booted Windows, and it isn't visible there. I have reinserted more than one different card a number of times. They are definitely upside-down with the connectors on top, and clicked fully into the socket.

    How can this be shipped with the primary storage expansion slot not working?

    I would prefer not to install an unsigned driver from an unofficial website in the hope it might work, particularly when some people report speed degradation or that it ultimately didn't fully fix the problem.

    Thanks for listening! I'm looking forward to a solution.

    Regarding Ubuntu, you may want to take a look here...

    Mr. Reis...
    I know this is a bit off topic but does this also affect the CR Z3735F processor? My friend is having issues with both sound and SD card slot disappearing permanently after the last Windows Creators Update. It might be a coincidental hardware failure, but I was thinking of trying your fix for the SD card slot and was wondering if the same drivers would work.

    Don't know. However, the problem isn't listed in "Intel Atom Processor Z3000 and Z3700 Series Specification Update August 2017" (Link).

    Don't know.

    The above solution works, using the windows 8.1 drivers, given the fact it seems to work for a few months then revert it seems likely that windows is "upgrading" the driver to one that doesn't work.

    All that seems to be missing is the ability to stop windows from upgrading the driver, this can be done by tellin windows not to.

    Control panel/system/advanced system settings/hardware/device installation settings/No.

    This should work, provided my supposistion is correct, that the reason it stops working is due to a automatic forced driver upgrade.

    It does seem that the 8.1 driver is slow, a class 10 card is not getting significantly above 4Mb/s, with most stuff moving a lot slower. It also seems that the SD card is NOT hot swappable, it needs to be in at startup and taking it out will "break" it until the next restart, not all the time but enough to persuade me not to :)

    If I can find one I may try a class 4, see if that's any faster (I seem to remember from my days of upgrading tablets that some had issues reading class 10s but not class 4s)

    Given I only use it for holding java, a kodi database, and a few apps, none of which are particularly speed dependant, this solution is acceptable.

    ETA - this is under 1803.

    All updates (Windows & drivers) are disabled on my two systems and the SD card still fails after some amount of time. Although some times a SD card will be recognized by Windows Explorer, but data can only be read from it. Attempting to write data removes the card from Windows Explorer (a HW restart may or may not restore the cand to Windows Explorer). This is a strange problem that propably needs some kind of HW debugging tools solve. I wonder if there are any microSD card emulators available that mini PC manufacturers may have a need for to debug such proplems.

    Thank you @MrReis

    I guess I will just have to wait until it fails before I can diagnose the problem and come up with a solution, a driver update was the most likely candidate but if you've disabled them....


    My SD slot worked fine until I upgraded to 1709, then it didn't do anything, no noises, no evidence it existed at all, apart from a driver that said it was operating normally with no problems.

    Hence my suspicion that it was a new driver, loaded when a feature update was installed. From a quick perusal of posts the timing before failure did seem to back this up, it could be working for months, then several people would post it had stopped working.

    I didn't try any fixes until after I had 1803 in (complete wipe, clean install), then I was bored so had a play.

    I'm currently not convinced that everyone has the same issue, but only time will tell (or official word from Minix who must be aware of this and have likely causes, done some investigations themselves)
     
  13. I do not use an SD Card but has someone tried disabling power management via the BIOS? I noticed by default it's set to "Efficient". If someone disables that, which will disable Turbo Mode and Intel Speed Step, that will keep the Processor at a steady frequency and may make the SD card use more reliable. I was getting some lockups until disabling those features in the BIOS.

    Me too. Just updated Windows to 1803 on my Z83-4, which worked fine but the SD-Card has been "disappeared". I get the plingy noise when I put it in and take it out. Using "Troubleshooter" with "Hardware" doesn't fix it. So I've got a slightly broken PC crippled by no SD-card.

    Why does Windows "updates" (which are meant to improve things) just give you a rather trashed PC afterwards?

    MINIX, can you please fix this?

    Looks like the BIOS update didn't fix the problem after all.... If I run the NERO video editor, while I'm editing video on another drive, the SD card goes to sleep and never wakes up. As soon as I try to access a feature the program needs to load from disk, all the USB ports reset, and the SD card disappears. It doesn't come back without rebooting. It causes NERO to crash and all my app icons that belong to apps installed on the SD card in the start menu are darkened. Really frustrating... I'm trying to get this video done and I keep loosing access to my programs. I'm thinking I'm better off install a USB SSD drive to install all my programs on.

    I'll try that and let you know. I'll reinstall windows 8.1 with disabling hardware update and see how it will lead me. thanks for the suggestion though.

    I tried MrReis' solution in his OP, but using the Test Mode method of replacing the SD Host driver failed. I just noticed that the driver that downloads in the instructions he links to at the end of his post seem to be for an AMD SD Host Controller or so the file name implies. If it's for the wrong device then maybe the post should be amended.

    Can anyone point me to a Windows 8.1 version for Intel that they have had success with?
