Micro SD Card Will Not Mount
06-10-2015 12:22 PM
- I have a new softwinerkf026 (also known as 9" Capacitive Allwinner A13) tablet* running Android 4.1.1 and the 32 Gbt Sandisk micro sd will not mount. (SanDisk 32GB Ultra Android Micro SD (SDHC) Class 10 UHS-1 30MB/s) I tried reformatting the mico sd on my computer with FAT 32 default settings and rebooting the tablet but it still can't be recognized or mounted. I also tried another older 1Gbt sandisk, tried reformatting the mico sd and rebooting the tablet but still not recognized. Under settings / Storage there are two places where it says internal storage/mount SD card but selecting either one pressing long or short does not appear to do anything. There is nothing there that says external SD. I have tried reformatting the 32Gbt card and 1Gbt card with FAT 32 default file allocation, exFat32 and also NTSF but still no recognition. Now its back to FAT32 default file allocation size.
I am wondering if this is a setting problem, a hardware problem or an android software or bios problem. Is there any way I can test if the micro sd can be detected by the bios? Your advice would be appreciated.

You can see if there are any errors on the card by placing it in your PC and right clicking on the card in the File Explorer. Click Properties, and then in the window that pops up there is a tab for tools. Repair should be there.01-21-2014 09:40 PM
- Thank you for your reply. There does not appear to be any problem with the sd card. In fact I have tried several sd cards below and none are recognized.
San Disk 32Gbt Class 10 for Android; tried reformatting FAT32, NTSF and sFAT32 and still not recognized.
Unknown brand 1Gbt FAT32; tried reformatting to FAT 32 and still not recognized.
Kingston 8Gbt Class 4; tried reformatting to FAT 32 and still not recognized.
According to the online instructions and instruction booklet this tablet can handle up to 32Gbt. When I sent an e mail to the online supplier I received the reply that only the 16Gbt class 4 in the link below will work on this machine.
16GB Micro SD HC MicroSD Memory Card TF for Mobile Phone Android Tablet 16G G GB | eBay
But if an 8Gbt Class 4 will no work I can't understand how the suggested 16Gbt class 4 should work so I am tempted to save my money and not purchase any more micro sd cards.
I believe a clue to the problem is that under settings/memory there is nothing that gives the option of mounting an EXTERNAL sd card. There are just two identical menu's for mounting an internal sd card. I wonder whether another setting on the tablet or bios problem is preventing the external SD card mounting option from showing up in the storage menu. I tried doing a factory reset but the option of mounting an external sd card still doesn't appear under storage.

- Thanks for your thoughts. As you say there is the possibility the card reader is bad. Convincing the Chinese supplier that the unit is faulty would be another problem as they insist only one recommended card will work; in the end I might have to live with using just the internal memory and put it down to experience.
Is there any other way I can test the tablet card reader? Why are there no options under settings/storage for mounting an External card? I figure I can't really test the tablet card reader unless I can mount a card. Is this because the tablet bios is faulty or is there another setting that is preventing this option from showing up? With Android tablets does the option of mounting an External card only show up when an external card is detected? What happens if there is no card in the slot, does the option of mounting an External sd still exist in the storage menu? Are there any suggestions why I can't see this option with or without an external card in the slot? All I can see are two parallel options of mounting an Internal sd card which don't seem to do anything.

- The micro SD card never did work. My guess it was a hardware problem of the cheap tablet. The micro SD card worked on my computer and another tablet. I was able to use the internal memory only. Sadly one day I dropped the tablet and the touch screen cracked so I kept it for spares. The lesson I learned is that its better to pay a little more to buy from a local store with a guarantee.
