[Q] SD card not mounting?

so, I recently bought a new sd card for my shift. I plugged it in to my phone and as my phone booted up, it says that the sd card is safe to remove. I found that weird. So I went into settings and tried to mount the sd card that way. Same message. Can someone help? I dont know what the problem is.

You should Format the SD Card before you use it.

Wow. I was having formatting issues but turns out the switch on my SD adapter was set so that writing was locked. Thanks a lot!

Hi,
Is the sd card loose in it's casing?

What have your tried?
Tried SD in a different Phone?
Checked the SD for errors?
Is the SD loose in the carrier?
Formatted the SD (fat 32 and primary partioion) from a PC?
Tried a different SD in your phone?
It does help if you do the basics and add what you've done in the OP

No, I'm never inserting my SD card to any other devices
Previously i checked it for errors,and got cleaned
After I purchased it,i haven't formatted....
I found this "un-expectally unmount error" from this last week...

I had similar issues with my sensation my sd would unmount unexpectedly it would vary from rom to rom. I found that if re flashed my current rom without a wipe it would correct the problem. It worked in my case hope it helps

I would try the reflashing rom idea above as its easy.
If that doesnt work transfer all the sd card data to your computer then format the card. See if that fixes.

[Q] Galaxy S3 not reading any SD cards?

My i9305T Galaxy S3 is not reading micro SD cards at all. I have tried using the cards in my computer, and they work fine. My phone, on booting has a notification that states "Preparing SD card; Checking for errors.", Then after a minute or two, has another notification stating that the SD card is safe to remove. I have tried with multiple SD cards, they all work in a PC, but not my phone.

so the phone shows nothing when browsing trough your files with a filemanager?
In that case Are you using the stock rom? some custom roms may have problems with the reading of big (64 GB) MicroSD cards.

Format using fat32 make sure it's not xfat

Same problem
I'm close to getting a new phone. My s3 won't read any SD card I insert in. I tried formatting from exfat to NTFS and nothing changed. Also tried rebooting, switching roms, clearing my SD card, and pretty much anything else I can think of.
Any of you guys know a solution, or a potential solution?

What is the maximum MicroSd card capacity tested ? 256GB 512GB ?

Hi
Had someone made long term testing with 256gb and 512gb MicroSd card with Honor 8?
Thanks

I don't own a 256GB SDcard, honor mentioned the max is 128GB.
However, it could be possible that it can handle a 256GB card, we need someone to confirm.

Ok, thanks, I ll wait someone to confirm...

On GSMarena, it says MAX is 256GB
That's good for you

yes, but sometimes gsmarena is wrong about some phone specs... would prefer to find a real user experience...

Ok, I'll try finding someone who tested it

The only thing i can confirm is that 128 GB is working fine. Been using one since i got the phone

I am just using two cards on 128...wait...what if 2x256...

One in sd and one is hybrid between SIM and sd.

Using the hybrid slot you can fit 2 sd cards and a sim card (one sd card on the sim card)

I don't know exactly, however I saw somewhere (I don't remember exactly where) a member tried it and it worked

Great, I will try it with an old SD card first

Report once done
I will try it works for you

In fact, thinking about it, are you sure you have 2 sd card and 1 sim card?
As I know you can have 2 sim card + 1 sd card, but not : 2 sd card + 1 sim...
Do you have a link to such hack or a photo of your setup?
Thanks

It is not possible to use 2 sdcards. There is only one hybrid slot. The other one is sim only.

After searching, you are right.
This tricks works as the following 2 Sim cards and 1 SD card

Phone doesn't detect SD cards

I've run into a rather interesting issue with my FRD-L04. My bootloader is unlocked and I'm running stock B385 with TWRP. No matter what I seem to do, the phone doesn't pick up any of the multiple SD cards I have.
EDIT: I've had a breakthrough!
The SD card appears to function ONLY IF the SIM card isn't in the tray. What on earth?
My SIM card was manually cut down from a full size one but I didn't think it would cause any problems. If I take out the SIM card and put the tray in with just an SD, it reads it completely.
I think this might have something to do with my SIM card being really old?

I was previously testing an early version of RROS on the phone but quickly made my way back to stock nougat, but somewhere in the process my SD card slot may have lost functionality. I don't think I'm able to run the marshmallow rollback process if my SD card isn't detected. TWRP doesn't let me mount any of the cards I have.
I've tried using the DLoad method for the rollback package and it failed at 5%. I don't think it detects the card at all.
Is there something I can try to do to make the SD card slot work again? I'm formatting my SD cards in the appropriate format (Fat32). I have a 16GB Lexar 300x and a 2GB MicroSD card from Samsung, neither work.

That is weird, try to format them with your computer and use exfat. See if that does anything :angel: do slow format as well if you have Windows. Not quick format.

You are also able to run the roll back packages if you make a dload folder in the root of your honor internal storage. :victory:

I just tested exFAT and it also didn't work on either card. A friend of mine just got the same phone and his SD card can even be accessed through Windows while the phone is plugged in, this never happens for me.

When did this start to happen? Do the cards work in another phone?

The cards work in every other device except this Honor 8. It may have started happening when I switched from B360 to RROS and then back again, but I don't think I've ever seen them work on the phone, even with EMUI 4.1. I get no prompts or information in the files manager, just 32GB internal storage.

If you never have seen it work I would take it to a service center and have them look at the sd card reader :/ maybe someone with more experience than me with this matter could help you on the forms if you don't want to do that.

My SIM card was manually cut down from a full size one but I didn't think it would cause any problems. If I take out the SIM card and put the tray in with just an SD, it reads it completely.

If the update process in recovery even reaches 5% it means the phone detects the card with dload inside it. I'd recommend u to try and rollback and see.

I've partially figured it out - It's clearly something to do with my SIM card. The phone will 100% recognize any SD card as long as the SIM is out, if the SIM is inserted it immediately disconnects the SD card.
My SIM card has storage on it for contacts because it's from around 2008 or 9. Should I try getting a new sim card and see if that fixes the problem?

May be you should Service centre. It may be hardware issue now but may worsen later so better to send it now or ask for a refund if it is still less than 10-15 days of purchase

The phone is 9 months old, I doubt it's still serviceable. I'm going to try upgrading to a new SIM card and see if it makes a difference
EDIT: I just reflashed the stock recovery from B360 via fastboot, and then ran the OTA for B388. The "quick update" failed so I chose "download full package" during the install as it worked with my previous update from B360 to B385.
It installed, and when the phone rebooted, my bootloader was relocked. It relocked itself via the OTA.
This also fixed the SD card issue.
I don't even know how that works. I should lock the thread somehow I suppose!

If you have any further issues. I'd recommend that your contact Honor directly as they should be able to help you resolve your issue quite easily.
