Micro SD Issue

[Hans Sprungfeld]

It’s obvious at this point, that there is some kind of hardware failure or constriction fault. It may work for you for some time, but eventually time and statistics will work against you, and the chance it will eventually fail will get higher and higher.

Let me try to format my sd card and i hope this is the reason why i cannot choose between internal memory and sd card in the storage

[Abu]

I formatted the sd card it shows in the storage,but it cannot be selected and apps cannot be saved in the sd card.what can i do? Should i root my tablet?or what else can i do,i suppose my tablet did not come with the feature to select between internal memory and sd card.guys your help will be really appreciated.

I gave up on it. I now beleive they use some sub-standard card reader which makes the situation much worst.

The sd slot of my iwork10 just totally gave up working, doesn’t recognize the card anymore, where it’s working on other devices. The weird thing is, this seems to be triggered when you boot from Android to Windows and vice versa, and if you do this a couple of times, the slot will break. Have no idea how this is possible though. Maybe there is a bug in the Windows or Android driver for the card slot, which somehow damages it over time. It’s one of the rare things I know where a software driver can damage a physical hardware.

ah shame. The issues with the SD card dont make a lot of sense at all..

Same issue with a newly bought iWork8 Air: my 32GB SD card worked great for about two weeks before became unreadable (among with other SD cards I’ve tried).

 

I’ve already reported the issue here:

Android reads tf card Windows 10 does not see it….

For the issue of unrecognized SDCard in Windows10, I just got it today I found out that it is a faulty working after the Windows10 update by assigning a signed driver by Microsoft.  Therefore, I update the driver with the Intel SD Host Controller (Deprecated) in Windoows itself and it works!  Damn it Microsoft, took me hours to restore the OS.

Thankyou Thamrong. I just wanted to confirm that this worked for me. Changing the SD Host Controller driver to the Intel SD Host Controller (Deprecated) got the MicroSD card slot detecting my 64Gb Sandisk card again under Windows 10 on a Cube iwork 10. It seems like whatever the new driver is that windows wants to use is not compatible with the micro SD slot.

Much the same as a lot of people here, my microSD card worked fine initially, but then after switching between windows and android a few times, it just stopped recognising that a card was even in the slot.

I wanted to try this solution, but when I go to the device manager, I have no less than THREE SD Host Controller’s 😐

I tried uninstalling all and rebooting but they all came back :O

Any ideas?

Uninstall the first two SD Host controller (and perhaps is a good idea to do the same with the other device with the “!” on it). Right click on the third SD Host (disable it, if you want, but not uninstall it) and then update the driver manually. Uncheck “Show compatible hardware” and click on “Have disk”, then select the older driver (Intel SD Host Controller v6.3.9600.16408).

The procedure must be done with device driver signing disabled.

1. Select the “Start” button.
2. Type “startup”.
3. Select “Change advanced startup settings“.
4. Select “Restart now” under the “Advanced startup” area.
5. Select “Troubleshoot“.
6. Select “Advanced Options“.
7. Select “Startup Options“.
8. Select “Restart“.
9. A menu will appear where you can press “7” on your keyboard to choose “Disable driver signing enforcement“.

SanDisk Ultra 128 GB microSDXC works very well in my Cube iwork 10 flagship Type C in Windows 10. The card was recognised without any issues and seems to be working very well. Unfortunately its not recognised by Android, as I probably have not formatted it.

The details of the microsdxc card are below I bought it from a local retailer:

Thanks for this, but this solution actually has a few issues:

1 ) If I uninstall any SD Host Controller, they come back after reboot

2) The “Intel SD Host Controller (Deprecated)” has a version of 10.0 . Do I need to grab this 6.3 from somewhere first?

If you see 3 “Sd Host controller”, uninstall the first 2, then  disable the third and use the proper driver to update it.

Take a look at this: http://techtablets.com/forum/topic/reading-sdxc-card/

The driver posted there seems to work for the Teclast X98, but I tested it on my iWork8 Air (that suffered the same SD reader issue) and it works as well, so it should be good for your tablet too, I hope.

I’ve tried the 8.1 driver and now the SD slot shows up in explorer – however, even with a card in the slot, windows asks me to insert a card…

 

I did notice after the reboot one of the 3 SD controllers shows v6.3 but the other 2 that were uninstalled show up as 10.0 again. Argh.
