[Q] [Pro] Problem with new microSD card

I've just bought a brand new 32GB Class 10 microSDHC card from SanDisk, but I'm having terrible trouble with it in my Xperia Pro.
The symptoms are that, if I move apps to SD (using the built-in method in Gingerbread), they will start force-closing. Files stored on the SD card sometimes won't copy from one folder to another. The terminal shows "I/O errors". Eventually the SD card will seem to disappear completely from the system. Sometimes the whole device will spontaneously reboot.
If I put back in the original 8GB Class 4 card, everything works fine.
I am sure the 32GB card is genuine and it works fine on a PC (tested with h2testw). I have tried re-formatting it in both a PC (using Windows and Linux, and using native OS methods with various cluster sizes and with the SD Card Association app) and in the device. However I format it makes no difference.
I haven't yet tried a different ROM on my Xperia Pro (I'm using stock Gingerbread at the moment, although I have rooted it).
Do you think a different ROM might help? Or is it just that this card isn't compatible with the Xperia?

Default [Q] [Pro] Problem with new microSD card
:crying: Hi see you have tried the re-formatting option this is good because first thing people start suggesting is re-format option lol.There can be a number of things wrong and I have seen many post's with same problem as you(and after trying lots of options it does boil down to a faulty card) Even when the card as been tested.Not saying that is your problem but it is strange your old card works and also this being a new card so untested on other phones etc.It would be good if you could test on another phone although this can be unpractical I know everyone as not got a spare phone.
Also as you suggest could be the rom follow the link below this might help
Try this option link http://forum.xda-developers.com/showthread.php?t=1010807 it may help:good:
With regards to moving apps to SD card I have always found using the app link to SD the best solution for me it as never let me down.Only thing with that you need to partition your card with minitool but it is well worth it because you can link apps with widgets without any problems.
Just a few suggestions maybe some others have some too:good:

most of app won't read SDCard

Hi...
This is my first post here.
I have a problem with my SD Card.
My SDCard: 32GB microSDHC, some application like music player and gallery sometimes can't read file on my ext sd card (but my file manager can do it flawlessly)
Furthermore, sometimes it shows PREPARING SD CARD on top of the screen, although I don't even do anything. I tried to re-mount it again. But the problem still sometime occurs.
This problem started happening when I changed my stock rom to Ressurection Remix, I thought this problem occurred because of the ROM. so I change it to AOSP. But still... the problem still existed. So then, I changed it back to my stock ROM (with restore option in CWM)
But yeah... Nothing happen.
Any idea?
P.S.: Sorry for my bad english.

extSdCard/sdcard 1 issues
I have a Note II N1907 (ATT) running Liquid Smooth with a SanDisk microSD ultra 32gb. I have been trying to figure this issue out since I bought this phone 2 months ago. I screwed up the original card that I transferred from my old phone some how by trying different things to make the phone recognize it. It worked fine in my HTC Vivid. I have root and am able to use root options to try to access this card of installation, but the best I have been able to do is use it for storage. And I have to manually move things to the card, because most apps do not acknowledge that it is there (can't see it). TWRP recovery can see it after I did my first ROM Flash, but I have to use internal memory for my first ROM Flash, because recovery mode was unable to mount extSdCard.
Is there a kernel I can flash to remedy this. I am no developer, but I think the problem is that the internal memory is also SD in type. I have noticed that internal memory shows up as SDcard0 (zero) and the after market sd card is sdcard1. Maybe the phone automatically defaults to the first sdcard and ignores the other (because it is only designed to have one sd card).
I am sure others have hard this problem with this phone. Thank you for any help you can offer..

As soon as I saw your reply I scanned for the words "Sandisk Ultra" and then I knew this was your issue.
I had a lot of SD card corruption with this brand and searching a lot on the web I found many stories of people having the same issues as I did.
My 32Gb Sandisk Ultra was the cause of many of my problems. 2 months on with a Lexar 32Gb, no problems (touch wood)

[Q] tab pro can save to some sd cards only

Hi guys.
let me say first that I am aware of whole writing/permission issue with KitKat.
And I am happy to use the build in file manager to copy stuff around.
But as I had some issues with my sd card(files were copied then dissapear etc) I bought Samsung! Sd card Class10 32GB and to this card i am not able to write at all!
I can format, create a folder but that's about it. Not able to copy anything using the 'internal' file manager.
Everything works fine if I can connect the card via OTG.
Any ideas? As i am stacked now with 2 SD cards I cannot use.
And btw with all this write restriction explanations. Why I cannot write to internal card slot only?! If it is OTG I can do anything with any application. Somehow all the explanations I have read do not add up in this part.
Any enlightment highly appreciated.
Cheers

Sounds to me like you bought a counterfeit /fake MicroSDCard , if you purchased it off ebay then chances are it's a fake. the packaging looks identical to real Samsung products and it is very hard to tell the difference.
Do you have a card reader for your pc, you can do a test on it to tell if its fake, there are several programs that can do this but the most popular is H2testw .
Take a look at these threads for more info

http://forum.xda-developers.com/general/accessories/fake-samsung-evo-64gb-micro-sd-cards-t2852818
The issue you are describing where files just disappear is a telltale sign of these fake or counterfeit cards, usually the cards only have about 2GB of writable space and the rest is bad memory.
Btw on a side note: I have no problems on my tab pro 8.4 , I have every single GB of my Sandisk 64gb sdcard filled. and have no problems with it..

Unable to move apps on SD Card after 6.0 update

Hello,
After upgrade and factory reset and micro-SD format, I am unable to move apps on the SD Card of my LG G4 H815.
I know that some can't be moved, but some can, and I am unable to move some games that before I was able to move, because I don't get that option. I also tried with a different micro-SD, although the card worked just fine before the upgrade.
I just don't get that options - I don't even get the option to format the external SD as phone memory, as I know it should do.
I wanted to post screenshots but I can't, because I'm a new member, so I'll try to explain:
- I go to Settings - Apps - choose a game - storage - there are only 2 options, clear data and clear cache
-I go to Storage - SD Card - settings - (here I have only Eject and Format, and if I choose Format, the only option I have is format as portable storage)
Did anyone faced a similar problem? I digged around bout couldn't find anything like this.
Thank you

I have the same problem, wen i upgrade to 6.0 i have some games with the option to choose were the data goes, less than 5.0 but i can move few.
I hard reset to stop batery drain and now i cant move any data from apps to SD card.

Same problem here! Even link2sd doesn't works...

Did you format your sd card as portable/external? How did you format your partitions and what formats when you tried link2sd?

Just tried it link2sd works for me using Fat32 on first partition and second one ext2. It had to reboot once but I guess it has something to do with my systemless root as it simply dissappeared and I had to reroot again.

The only option is portable in the format on the phone. I was under the impression under marshmallow you would be able to format either to portable or internal.

Just checked move 2 sd isnt showing up in options my guess it has something to do with the new internal/external feature, did not test with link2sd only linking tested and that works for me. I guess that you can only format as external is caused by stock rom. After all I have read internal seems not to be a good choice for mobiles with enough internal storage

Link2sd was formatted as ext4 that worked on lolly, but the big problem is I formatted as external (only choice) and the "move to sd" button does'nt appear at all! Maybe I should format all the sd as ext4? In a nutshell the 20B is using my sd as an otg storage, can read and write, but not considered by games and so (luckily the camera srill save pics and vids on sd).as far as I can see there is only thi thread and we are the only one thata have this problem!

I search about it and seems, LG dont implement 6.0 feature to use SD as internal memory if SD card have the minimal speed requirements

Try ext2 on second partition then it will work. I only have the problem that it wont mount at reboot, I always have to wait after complete boot and some time more until it recognizes second partition and mounts it. Perhaps an issue with systemless root (supersu 2.65beta) I am using but as long as no system apps are linked there is no problem with this (and I dont reboot often)

Ext4 on link2sd used to work, but in 6.0 (20b) it looks like I deleted a lot of "trash" so I was able to reatore all the app without link2sd and I would like not to use it, just to move app to mi samsung64gb sd to save other internal space for the future.I know it doesn't move the complete app, but one day maybe you will need even just 5mb...never say never....and one day you may need even just 5mb of internal memory...never say never... anyhow it store lictures in my sd, so I'm really afraid is about a limit of the rom or the memory card (I miss the format as internal memory too, while someone has that option on G4, am I wrong?) I have the classic silver 64gb samsung micro sd not the ultrafast version I used to make 4k vids on my old S5!

I personally bought link2sd as the old move 2 sd didnt work well with my samsung galaxy tab s, most apps crashed but using link2sd they worked (not all but most of them). As for SD card I have a sandisk ultra 128GB and no problem recording 4k to it, I use the mod with the highest bitrate from the forums here

I was talnkig about my SD not to say if I can record or not 4k (we are off topic here), but just to say that is NOT the ultrafast that samsung requires for recording 4k video without modding.
I just mean that now I have a "Samsung MB-MP64D/EU Micro SD XC EVO, UHS-1, CLASS 10 orange/wite" not the "Samsung MB-MG64D/EU micro SDXC Pro 64Go Class 10 UHS-I silver".
The latter was required by samsung to record 4k video=superfaster compared to the hal priced one I have.So, MAYBE, the SD does the difference in Marshmallow, it detects the kid of SD and allow us to use it as internal memory and/or to move the apps on the sd without the Link2SD app (for the record, I used ext4 withou problem with lollypop, now Link2SD doesn't find the partition, I won't waste time trying other ext till my phone will be full).

Merge internal & external memory in Samsung J2 Prime

Hi guys! First of all, I'm not sure if this is the right place to ask this question.
I have a Samsung Galaxy J2 Prime, with 8GB of internal memory. But 8GB is not enough in any way for android, upgrades & apps.
Ok, I read that Android v6.0 has support for merging internal and external memory in the way that Android reconizes it as single storage. My problem is that my phone doesn't show me that option. Just says "Format as portable storage", not “Format as internal” as I read at a forum. I have installed a SD card class 10 but this is not the problem.
This is a Samsung custom setting? I need to root my phone? It's possible to do it?
Thanks for any help!

Yes, Samsung disables this option from all their devices with the excuse being: "If your MicroSD card fails, which is totally common to fail, you will lose all your apps and apps' data" (but in my opinion and a lot of people's opinion, they disable it to force you to buy a device with bigger storage )
There are two ways to do this, with root and without
If you have root, you can use the app "Root Essentials" from the PlayStore. It'll show you step by step on how to set up adoptable storage.
If you do not have root, you have to input some commands via adb, which I do not know how to do. You will have to research this on your own.
But, just as an advice. Even with adoptable storage, it doesn't work as you would expect it to work. Not all apps will be transferred to the external memory and you'll still get the message that you are running out of memory even if you have 7 out of 16 GB used up. It's not that great.

Hello, i would like to ask about this too.
I have adopted a 16Gb sandisk UHS-I SD Card to my 8Gb Samsung J2 Prime G532G, but the storage at file manager is still 8Gb and no SD Card access. BUT at storage settings it shows 13.40Gb used out of 22.80Gb. So, where did the rest go at file manager?
