sd card does not work - MTCB Android Head Units Q&A

My sd card does not work, can i upgrade from usb? Same steps
thanks

1) make sure any SD card is FAT32 formatted and not ExFAT. These can only understand FAT32 formatted storage. Windows will only format anything 32GB+ as ExFAT using the built in support, so you will have to find a utility on the net to do FAT32. ALSO, make sure the SD card is not fake, there are a ton of them that are out there and they look perfect, and are sold on Amazon.
2) Yes, when you go into recovery mode there is an option for USB which will look for the first USB storage device. That is actually how I do all my updates because I don't like pulling that little sd card out everytime, USB stick is easier.

Ok, thank you, I'll see if it works, my unit only recognizes usb2

how do i know which sd card do i have?

i want to use this app:http://forum.xda-developers.com/showthread.php?t=1889550 but i see it dosent work on exfat and i dont know how to know if i have exfat or fat32 please help ..
I'm using directory bind (latest version) on exfat and it works fine for me. You can just put the card in your computer and go to its propertes, it will tell you which format it is on.
64GB micro sd cards usually come with exfat format out of the box. 32GB usually FAT32
i think most sdcards are fat32 by default--may be wrong--but you can research phone specs or Google sdcard specs for n2.
Not aware any card comes with exfat--if you are original owner it should be fat32
you can also use partition programs like gparted or sdformatter that should list the sdcard and say how it is formatted--
either way backup sdcard first and even phone

thanks bro! however i already found a solution and i want it to share with you since i thinks its a lot easier. i format the sd card using the computer right click>format> i choose ntfs and quick format, it will fail. after that insert the sdcard on your phone and the phone will automatically detect that the sd card needs to be formatted. atfter that format it with the phone and thats it

Micro SD Card constantly needs formatting

My external card which I was hoping to use for Google music storage refuses to stay mounted . I also have to reformat several times per week to even use it. I've got two Samsung 64Gb cards and they both do the same thing. They work fine in my laptop!

I had the same problem with my phone. I found the problem was that they were exFAT and not FAT32. Changing this is hard because most software doesn't reformat anything bigger than 32 GB. If you're rooted, "AParted ( Sd card Partition )" by sylkat was able to reformat the SD card and fix the problem. It changed mine to FAT32 and my LG G3 no longer needed to format it.
There are special programs for Windows Vista/7/8/8.1 that can do this as well, but I didn't do this so I cannot help you. I will tell you that'll you'll need to hook up your SD to your computer via reader, card slot, or any other way you're able to connect it. If you're not rooted do a quick google search to format it via computer.
Hope this helps!

micro sd card problem

I'm having a problem with this brand new 32GB kingston canvas select micro sd card. Bought it for my dad, he's using a 100% stock G5. When first plugged in, the phone asked if the card was going to be used for internal or external storage, chose internal because my dad is kind of an app maniac (yeah, I know, tried to get him to stop but he's stubborn), formatting stopped at 30% for 10 minutes. Rebooted the phone, it stopped recognizing the sd card. Tried it on my phone, which is also using a 32GB kingston sd, and it didn't recognize it either, on the PC it works fine. Tried formatting it to every file system known to man and none of the phones will even know there's an sd card plugged in when using that particular sd card, but both will work fine with other cards. Could someone give me a hand with this?
I would use minitool (windows) or gparted (Linux)
Delete all partitions on sdcard
Create a new fat32 primary partition and format it

thanks for the suggestion, but it didn't work. it's as if the micro sd isn't even inserted into the phone, yet on pc it works perfectly. it even passed hw2test!

Other than factory resetting the phone or trying a different sd card there's nothing else you can do

SD Cards with Filesystem other than FAT32

Hey,
has anyone had any success with using SD cards formatted with something other than FAT32 on the Redmi Note 8 Pro? The 4GB file size limit and limits on usable characters in file names (although there might be easy workarounds for that one, haven't tried yet) make FAT32 a really poor choice for me. I have tried formatting the card with exFAT, NTFS, as well as ext2/3/4, but it recognized none of them. I get that Xiaomi haven't licensed exFAT or NTFS, but I don't see why ext2/3/4 wouldn't work. Probably just disabled in the stock kernel?
There's also this option to use the SD card as an extension to the internal storage. Not sure what filesystem that uses, but it doesn't seem like a very transparent and portable thing to do.
My device is rooted, so I'd be interested in root-only options as well. It's probably possible to get it working with external apps that include FUSE drivers (I have exFAT working using EDS on another device), but I'd prefer a "native" solution.
Thanks!

When I cannot answer your other questions ATM, I can already answer that one since I tried it with other devices and this one is no exception.
As you suspected, that's definitely is not a portable solution. You can no longer use the SD card as a plug and play portable solution.
That said it does not sound like a very good idea to keep ejecting that SD tray to transfer files, that would be done more easily with either an hybrid USB-C USB-A pendrive or just an OTG USB-C cable.
However that's always good to have an SD card in there to backup important files with a few thumbs presses at any time.
Speaking of USB-C drives/OTG cables, it is possible those do not have the same limitations SD card might have when inserted internally. I have not looked into it just yet because I usually do not put files that big on my phone, but I can see it could be a problem (large video files or backups for example).
Hope this helps (a bit).
Regards.
PS: As root have you tried to manually mount those drives formated as ext{2|3|4} from a terminal?
Try this, -
Connect SD card to PC.
Do back up of important files from SD card.
Open 'Disk Management' in Windows.
In 'Disk Management' delete all partitions on SD card.
Leave SD card unformated.
Download software 'SD Card Formatter'
Format SD card with this software.
Test SD card on Redmi Note 8 Pro.
