32gb microsd SDHC problem!!

Hi,
I bought a trancend 32gb microsd SDHC class4 card for the note about 10 days back..Worked fine for 2 days then suddenly stopped working...Stopped working means does not get detected in the phone or on the laptop (there is no option for mount/unmount on the phone)..Ive tried my older 8gb card on my phone and that works fine..Ive also tried the screwed up card on my blackberry bold and it doesnt detect there as well..
Well, i thought its the card's fault and ordered a replacement...
They sent one and same story again!! worked for 2 days and same thing again
Now i dont know if its the card's problem or my phone's..Anybody with any idea??
PS - i am rooted and on criskelo v11.2 with speedmod 3-13 if it matters...also both times i had about 15gb of data in the card...
ive also tried blowing and cleaning the contacts..also tried inserting a piece of paper in the slot to cancel out loose contacts but nothing works
Thanks..

What was the file system on the card?

are there specifications to follow??

Very strange problem , but I am facing the same problem with a Trancend 32 GB card replaced twice and worked only for 1 day and then stopped recognising , not sure if it makes a diff the Mobo was replaced by Service center about 4 months back ,, may be a mobo fault? but my 16GB card just works fine

same thing happened to me also ..... i replaced a new 32g card let me see if it works fine or i will never buy another 32gb trancend card

since both r indians ill talk in tat context
flipkart now says they wont replace anymore and will refund the amount as credit! He also adviced that sandisk works better on the note for this capacity..i dont know wat logic he had! please do update if u find a solution/alternate
@anirudh - which company is that 16gb from? maybe ill have to make do with 16gb since 32 doesnt work

32Gb micro SDHC class 4 by Transcend, not recognised by GT N7000
Hi All,
I'm using a GT N7000 on Official 4.1.2 XXLT5 (recently updated). I'm using a Transcend microsd 32gb class 4 for about a year now with this note. But I'm facing this issue of 'blank SD' and 'unable to format' from 2-3 months now after I updated to one of the official OS upgrade.
I've tried reverting back to all the earlier versions of Android where it worked fine, but there seems to be no change. I can read the card using an external card reader in my laptop, but not through the phone.
I've tried formatting it to all the possible types (NTFS, exFAT, FAT32), nothing seems to work, for the note. I can read it on PC though.
I tried reading the same card in another device, but now it's not readable in that as well. Any suggestion/solution, much appreciated.
Thanks

Boot into recovery mode and go to mounts and storage. From there format the external memory card (format /sdcard). Alternatively you could try with a format from the "storage" in settings.

Use the card reader with ur pc. Go to disk management and format the card FAT32. Before formating, delete the partition/partitions on ur card. U should get unallocated space. Create partition and it should work. The big problem is that u may see some problems between note and 32gb card. The phone it may restart and u should go to recovery/download mode to restart it... good luck.

64 GB is not quite supported but can be made to work... -- my 64 GB Sandisk was formatted with ExFAT file system, which works fine with newer versions of Android JellyBean but not earlier. You may have to reformat as FAT to get it to work.
Do some searching on this topic, you'll find more information.

64 GB is not officially supported but works flawlessly in reality. Just format the card and you're good to go. I use a 64 GB card too.

Same here :good:

A whopping Class 10 64GB card from Kingston worked for me here!

There are lots of posts saying they work fine ,as mine is doing. Try looking,google
From box 13......

Threads with rich and objective information like this are always great to read.
Thank you, guys!

I have a class 10, 32 GB but I think that I'm going to buy a 64 GB

I ordered one from Amazon which I should get tomorrow.
Now I have a Samsung class 10 32GB which I am gonna mount in my girlfriend's Ace.
So, if I did understand, I only have to format from the phone and I should be ready to go. Is it right?

Yes.

OK. I give you a thanks.
I've got it right now from my mail box and I'm transferring all my data from the 32GB one.
My Note recognized the 64 GB immediately.

64 GB pendrive
Yeah, I could connect 2 of my 64 GB pendrives.

In my opinion, it is always a good idea to "re-quickformat" a microSD card after purchasing, and BEFORE you mount it in the device preferred. It gives the chance to the circuit to be "revived", and this is much better done through a computer, than a smartphone or tablet.
My SanDisk 64GB microSD arrived with exFAT file sytem and an 128K cluster size, which is the default by the factory. I re-quickformatted it with the same factory parameters, as those were suitable for my needs.
Let us note that with bigger cluster size, comes better performance with the expense of more wasted (slack) space.
The reverse applies to smaller cluster sizes, of course.
It's a good thing that the newest Jelly Bean Roms (I use this: http://forum.xda-developers.com/showthread.php?t=1970626) DO support exFAT!

[Q] 64 GB MicroSD card & OTG cable.....

Hi Fellow FLO owners!
Has anybody had any luck when using a 64 GB MicroSD card with their OTG cable?
I have already unlocked the bootloader and loaded a custom recovery and rooted my device, I then replaced my 32 GB microSD card with a new 64GB hooked up to my OTG cable via the USB port. For the life of me, I cannot read the newly formatted 64 GB MicroSD card? Has anyone tried this yet with a 64 GB sized card and was able to read their data? Was there something special I needed to do as well, download some other app or what have you?
If so, please tell me HOW you got that working or PM me.
Thanks!
Far-from-new-to-rooting and unlocked bootloaders, but, baffled nevertheless.

While I don't have a tablet in my hands yet to confirm or deny this theory, my guess is this:
A 64GB microSDXC card is going to come preformatted with exFAT; your stock Nexus 7 can't read exFAT partitions.
You can either reformat the card, or use a program to mount exFAT partitions (like this thing), or install a ROM that can read exFAT partitions (CyanogenMod 10.2 can do so; so can others, probably).

Ah, that sounds good, I shall give it a try and report back on my results! Thanks very much!!!

Oh, before I forget to mention it:
What recovery are you using? There's a very good chance it will be able to read / format the card for you.

Really? TWRP v 26.00
Oh well, I already reformatted it to NTFS now, the Paragon App didn't work. Currently, recopying files over now to the microSD card as we speak, will take about an hour.
Thanks again!

[Q] Micro SD Card Compatibility?

I have a T-Mobile Samsung Galaxy S4 (jfltetmo) running Liquid ROM v2.37 and I was wondering if this ROM is compatible with a 16 or 32GB Micro SD Card, or do I have to format it in a certain way?

Put it in and see. Not like your phone will explode start WWIII...
But yes, it will work just fine.

It should work just fine but just to be sure it would be best to format
the 16 or 32GB card using a windows utiliity which formats in fat32.
That way you will never have any issues or problems with it.
Here is the direct download link for the fat32 formatter:

Yes even 64 GB - some roms l;ike Wicked which I have I noticed the SD card needs to be formatted in fat-32 not the standard out of the box format. Then it works fine.
Go to the Play store and search APARTED I use it and it formats in fat-32 super fast and easy! You can even use that program to partition it. I was on Wicked V8 (4.2 Android) using a 5 gig partition and links-2sd to move all apps and data to the external SD. Now when I re-do the phone to V9 (4.3 android) if It has Apps 2-SD which it should, I will still partition and see if I can't get all the apps on a certain partition and my stuff on another
So long story short yes will work. Any issues like won't mount aka not showing in storage - external storage - just get APARTED from google play and use it to format the SD card in FAT32

[Q] MicroSD Question/issue

I have the Tab pro 12.2 KK4.4.2 and purchased a patriot Micro SDXC 64 GB. My question is similar to other posts and I will try the posted solutions when someone can confirm the validity of the SDcard. Samsung specs for the Tab(SM-T900) state support for micro SDHC up to 64 GB. All of the reading I have done shows that the largest SDHC cards is 32GB and anything larger is a SDXC. So is my64GB SDXC card actually supported in my device? I have not been able to write MP3 files from my PC to the card or any other files with any success. Put I am able to do it fine on a smaller 16GB SDHC card. Can this version SM-T900ZKAXAC be rooted?
Thanks

I contacted Samsung and they are going to escalate the issue up the chain. It seems as though the tablet only supports Fat32 file system, while SDXC cards are only can only be formatted using exFat or NTFS. That being said I tried formatting my card with NTFS in hopes it might allow Fat32 after but it wouldn't format using NTFS.
Is no one else having this issue, as I have not seen 1 other post regarding this particular problem?

Mossey, do you happen to have a Windows computer?
plug the sd into a different phone if you can and connect as external. Click Start->My computer->right click and format to Fat32. I do this all the time

I thought for second you had the solution. I have another tablet and tried reformatting using it. I had the stick showing fat32 file system but it was 32gb vs 64gb. But the tablet recognized it initially, so l reformatted using the tab, but now the tablet looses the sd after it writes a few files to sd. Then if I try to view files on the tab, I get a message that the ext sd card may not be readable.

Hm interesting, it seems like it might be a permissions issue.
Can you try doing this on a device that runs something before 4.4.2? Kitkat is known to cause lots of problems with SDcards
hope you find the solution.

Again- Thanks. I thought it odd as well and it didn't add up. Although the SD card was working OK in my new Sony camera I decided to return it to C.C. for an exchange, voila problem solved. This still tells me that Samsung Technical support is useless. Everyone spent a lot of time trying to solve this issue. I still am finding odd things happening with Kies but I have found some work a rounds.
