SD Card shows wrong size/Free Space (double) 128 >> 256 GB - Xiaomi Mi A1 Questions & Answers

I have an old Lexar microSDXC 633x UHS-I 128GB (previously used in 5 other Android devices)
I opted as internal storage.
It shows up as 256GB and free space calculations are cuz of that messed up.
External Apps can either see the onboard or the internal memory (not both)
Should I be worried? (Or how I can test its all working good?)

Can you try formatting it once from inside the phone and not the computer? Be sure to take a backup first

Not sure it would make a difference.
I already did that. It would not let you use it as Internal Storage if I did not Format it first.
And you cant take a backup of internal SD. IIRC it will not be usable and apps that had data there will be also corrupted.

A couple of options. 1st is to try a cleaner like ccleaner and see if that sorts it by cleaning the cache, last resort is a factory reset which has worked before now. The other thing is that it could be either a fake card (possibly) and/or damaged but the last is highly unlikely.

Tried ccleaner. Factory reset I will try only if I see any issues.
And ehm... no ... the card that I bought in a normal shop and used for many years (as I said) is not fake or damaged.
Antutu reports all correctly, so this lets me to believe its just Xiaomi or Oreo issue.

Hmm weird that it is showing 256gb as the phone specs only allow up to 128gb. My guess is the card itself as I have a 32gb in mine and it shows up fine.

Man, I'm having this exact problem but with a 128GB Sony UHS-1.
This should be a bug in Oreo.

I have the same "issue" with a brand new 64 GB Samsung SD card. And: before updating to Oreo, the storage capacity was shown correctly. So this seems to be a bug in Oreo. However, I don't find any other comments on this on the Internet, so it's probably limited to the Mi A1?

On the same Oreo version I had no problem with 64 GB Samsung Evo plus but found bug with same type 32 GB card. Not native apps shows correct size but Android says that it's half of memory occupared by system files

My wife's A1 has a problem with SD card. It doesn't format either as storage or as internal memory. It's a original Sandisk 64Gb UHS-I. She used it in her former Moto X Style and I formatted in a LG Pad 8.3 without problems. I took a crap SD Card and it formatted as storage without problem in A1.

I am experiencing the same problem, this is still an issue. If anyone has an idea for a fix, please let us know.

Yes, same problem with a genuine Samsung EVO Plus 64GB SDXC card. Shows up as 128GB card with 64GB used when formatted as internal system storage, but as a 64GB card when formatted as "removable" storage. So it's a phone-specific bug in some way.

Same here, my phone is 32gb, installed a 32gb sd card and format as internal, now its show total 96gb and the card is 64gb with more than 32gb used.
I think it add internal onto sd card and show that 32gb is already use, which mean its show 64gb sdcard but actually we get same useable amount.
Btw its still show correct available free space so its not a problem.

Hello ! same thing here with a samsung galaxy s5 sm-g900f on resurrection remix oreo 8.1 with four differents card : size 16 gB on esxternal memory , 32 GB on internal memory and also for 128GB it goes to 256GB on internal memory
just want to try with android 6.0.1 with the patch which unlock this feature https://forum.xda-developers.com/samsung-a-series/general/patch-adoptable-storage-enabler-t3470648 and its not good either. i can see the right size of the phone 16GB , the right size of sd card 119 GB but the sum above show: 256GB

I do have the same problem with my LG G6 and Samsung Evo Plus 128GB memory card.
If any workaround, please post.
But it doesn't affect the functionality, it works as intended. But when I see the storage in settings showing odd numbers.

I have the exact same problem. Same SD card. Although everything seems to work okay. Btw. I am on Android Pie.
In Solid Explorer the internalstorage isn't even shown. Only the SD card. Unlogical since the SD should expand the internal storage.
Imho a major f*ck up.
How can you trust your phone if the storage info is unreliable. ?

I have the same problem. I think it's a bug. See here: https://forum.xda-developers.com/ra...al-storage-t3782347/post79349711#post79349711

Hi,
Any news about this bug ? I have the same on LineageOS 16.0.
Thanks

SD card damaged

Hi everyone,
i have a G900F running on the current version of the ALEXNDR Rom, rooted, Knox 0x1, Android 6.0.1.
I have my SD card formatted as (mixed) adoptable storage (via adb), so I have 50% of space as SD card memory, 50% as adoptable storage.
And now for the problem: The SD card is repeatedly shown as "damaged". As soon as I put it into my PC, it'll work without any problems, but the SGS5 will work for quite a time with it, and then suddenly shows it as damaged and will not mount it unless you format it. It usually happens when a larger amount of data is written to the card.
So I thought that the card might really be damaged (was an old and small and slow one) and went vor a SanDisk Extreme 64GB card - same thing here. Then I read about some problems with Samsung devices and SanDisk cards (may the be true or not, I dont know) and swapped it for a Samsung 32 GB Pro SD card - same thing here.
Does anyone know why this is happening and how to stop it? Or will the adoptable storage just not work?
In addition: I could reproduce this when I was downloading Videos to the SD card from Amazon Prime Video for offline use. Seems that a) this is a large amount of data and b) split into thousands of small files. I dont know if its the number of files or the amount of data, but when I deleted the folder on my PC and put the card back into the phone, it suddenly worked perfectly again. Any ideas on this?
Hey there how are you?
I recently have had an issue with my samsung 128 sd card that was formated in a 50/50 mix from adb too.
As the sd card was formatted in exfat I posted an issue on the exfat home page. https://github.com/relan/exfat/issues/49 I was provided with advice on my mac on how to reformat it using the dd command. This was the only command that I came across which gave me an input output error indicating a hardware issue on the sd card.
I have since purchased a new sd card. I'm thinking of formatting it as either an ext4 format or f2fd format to see whether this makes an impact of its longevity.
Hope this helps.

One query about adoptable storage in Nougat

Guyz one small help. 2day i formatted my sd card as internal storage on my g4+ then I had to copy all the files that were present before formatting sd as internal (i had taken backup before formatting) but when I connected my ph to pc after formatting I was able to see only phone storage so I copied everything in it having no other optionz then in ph storage settings I kept those files to be moved to sd card so it's been around more than 20 minutes moving is stuck at 27% ! What should I do now?? Ow crap i can't even post the screenshot as the system is detecting the storage is busy

When you format it as internal, it will not show your SD card because it's considered as internal storage itself.
That's literally what the function does.
For eg you have 32GB as phone internal storage and if you formatted your 16GB card as internal you would have 32+16 GB as your total storage.
And yes it would show you as Internal Storage as the SD card is now considered part of it.

If you don't have a high quality sdcard with U3 (not just high read but also high write speeds) then it make take a long time. I've just done this with my wife's Moto G4 and I gave up. It started moving but hung. I ordered a PNY Elite sdcard with 90Mb/s write speed. That worked much better and it moved stuff to the internal formatted sdcard.
One thing that is important is that it takes some time before it reports the entire internal storage that includes both phone plus sdcard storage. A reboot will help as well to have the sdcard be recognized by running apps.
That is just my experience. Your problem may be different.
The usual junk speed (or even normal speed) cards won't cut it as adapted storage. You need a card with minimum "UHS-I Speed Class 3". That's usually 90MB/s read and 80MB/s write average speeds. See the attached table.
The internal memory on the phones is much more performant than the average SD, that's why is more expensive when buy it in the phone (like when switching from 16 to 32 to 64GB internal, if everything else would stay equal).
PS: Some of the cheap chinese cards that are sold on eBay are really bad fakes, or just plain rejected cards from real manufacturers (meant to be destroyed but stolen and re-sold) and that storage will fail almost immediately.
I had this same issue. I sent my old SHIELD tablet back for RMA and got a new one. I got a new official samsung SD card, popped it in and formatted it to internal. So when I did that, it didn't combine the SD card with internal storage like it was supposed to. It just disappeared. 7.0 gives you the option to format it back to portable storage. So I did that and the SD card is usable again, but as separate storage :-/
something is definitely wrong.

SD card problems

Hello I have a Bolt and I am having problems with my SD card. I insert it and the phone recognizes it and mounts it as portable storage. I then format the card as internal storage which seems to work ok. Then I attempt to migrate data and the phone hangs up at 0% and never appears to actually migrate data.
I do not think the problem is the SD card, as I insert it into another phone and it works fine as internal storage. I have tried multiple cards in my Bolt and have the same issue. This is the card https://www.amazon.com/gp/product/B01HU3Q6F2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
any help would be appreciated.
You card may not be good enough to format as internal try putting it in and formatting as external I believe it has encryption I had to format card with phone then add my files

Considering this is a UHS-I Card, You shouldn't have any problems.
One thing I will recommend is formatting it twice. Format as internal then reformat as portable, reboot, and reformat as internal and then try migrating your data. That usually did the trick for me. I had issues with these SanDisk Cards though so be careful. I've had two of them die on me already. I RMA'd those and I am awaiting a exchange but I went and got a Samsung SD card as a replacement and haven't had any issues since. For some reason, I've always had to format all my cards twice for adoptable storage to properly work, regardless of device.
Edit: UHS-3. Those Speeds tho ?

I had the same problem until I bought a class 10 SD card now I formated it as internal storage no problem so it went from 32 gig online storage to 64 gigs with the 32 gig expansion using sd card.

MicroSD Corrupt/Errors

Hey all. Have tried multiple MicroSd cards from different brands and I always have the same problems. It reads as corrupt, photos/music cannot be read or seen, and it happens every time. This happens whether I format it as Internal or portable. (Portable is preferred.)
My G5 Plus is rooted, and is on Android 7.0. Would appreciate some help, not having any luck with anything I do.
I'm rooted and running pure nexus and haven't had the first issue with my portable formatted 32gb card. Are you on stock rom?
My kingstone 32Gb works great on stock, check if your SDs are fake. There are several test apps to check this
If it's asking to, let the phone format the card, I don't mean internal vs portable but an actual physical reformatting of the card. Backup any data on it, let it format, restore the data and see if that helps.
My good quality SD card used on a previous phone would give me the corrupt error on some roms but not others, and other users weren't having the error with their cards that I was, so I finally just let it reformat once and haven't had the problem again on any roms or stock.
Wondering if it maybe has to do with size of card? You both are on 32gb, but I am running a 128. Thoughts?
It is very possible my card could be fake (ebay purchase), but why would it run fine in other devices? How can I check for fake? It reads as a 125GB or whatever it comes out to when formatted.
Don't know where to do just a normal format. I have formatted it as internal and portable (which I want) and the same problems always resurface.
Thank you all for helping.

make a search over internet a generic site or in XDA a thread
They are used to flash the firmware of an old sd card (4, 8, 16 GB etc.) with a bigger one, so it will detect as a eg. 128GB but when you try to write more than 4, 8, 16 GB it fails. So i suggest to buy an original micro sd, you will pay more but it won't fail

Anyone having any issue with Sandisk Ultra 128GB MicroSD card?

not sure this is just me or does happen to others, I had the M2 with the latest firmware installed, and for no apparent reason, I had tried 3 Sandisk Ultra 128GB MicroSD and all 3 had show corrupted SD Card after being formatted using the phone as portable storage, but the strange thing was, if I use the ADB and partition the SDCard as Internal storage, all 3 cards just work fine.
all the 3 Sandisk cards were tested ok and were used all the while in my old phone, my PSP and some other devices. So it is not an issue with the card.
Any thought on this?
Well i have a 64 gb sandisk ultra...a brand new one...i did not face any such issue but i also didn't format using the phone too...i read somewhere that the new fota is responsible! I don't have links or proof to back that up at this time!

Try formatting as FAT32
I am using a 64gb sandisk ultra card since day one. I also formatted using the phone and have zero issues. It works with file transfers from pc, copying/deleting/editing to and from phone memory etc.
