I have 2 CHUWI tablets. CWI526 Model HiB PQ64G45160600054 AND CWI527 mODEL 4G+64G Hİ10 LQ64G42161204564 unfortunately no matter what I do the sd card reader does not seem to work on CWI527. It works fine on CWI526.

There are 3 solutions posted so far: 1. Plug in a usb drive to tablet and launch Windows, any usb drive, and sdcard will be recognized: DID NOT WORK. 2. Launch into BIOS settings and save without saving then when windows launches shut down or sleep and then re-launch windows. sd card will be recognized: DID NOT WORK 3. Change bios settings for sdcard from ASPC to chipset\>south bridge\>lpss & scc _configuration_ \>scc _sd card_ support change “acpi mode” to “PCI” . DID NOT WORK. Does anyone have any ideas how to work SDCARD on this device since without it I have very limited space and I dont want to use it around with a pen drive sticking out. ---

So, your tablet is dual-boot? Does the card reader work in Android? ---

Yes I have 2 dual boot tablets. I have 2 sd cards, a 4gb formatted as NTFS and a 128gb one formatted as EXFAT No they are not recognized in Android as well. however on Windows the 128gb sdcard was recognized for one time when I was trying to plug it in first few times. Never again. Windows recognized sdcard being plugged in however Device Manager shows the second SD STORAGE CLASS CONTROLLER as “Device Cannot Start” ---

It’s most likely a CPU problem. Try writing to [service@chuwi.com](mailto:service@chuwi.com). ---

I have been working on this problem for many months myself. It is apparently a problem with the BIOS. They do not want to fix it so we are stuck with the problem. I have tried all the supposed fixes too and none worked any longer than a reboot. You have three choices. Either make the tablet all Android or all Windows making more storage space. I choose to change my android partition to 20GB and do a clean install of the latest Windows 1909. With this set up I am able to load any apps and Windows programs I want. I use storage on my home network for files or you can use cloud storage for file. One last suggestion. I made an image of the tablet using Acronis once I had it all set up because I also have been having problems with the Android partition storage shrinking with no apparent reason or fix. This way I can restore it if the storage mysteriously gets filled. I also bought a very small USB drive but do not like having it stick out too so I do not use it much. **Link how to load newest Windows** > [@\[Other\] \[Tutorial\] How to compile an install file of the latest build of Windows 10](https://forum.chuwi.com/t/other-tutorial-how-to-compile-an-install-file-of-the-latest-build-of-windows-10/1174): > > How to compile an install file of the latest build of Windows 10 for a Chuwi tablet I would like to reveal the essence of the problem in a few words first. As you know, Microsoft usually releases its Windows 10 updates every half year. Updating process lasts an infinitely long time and often ends in a failure on your tablet with too small eMMC disk space and minor CPU performance. Therefore, it’s very important to have a ready-made package for a clean Windows installation.
