[Q] 16gb Sandisk Card not recognised - Desire Q&A, Help & Troubleshooting

Hi, I have a Desire which has been running many different ROMs today since i just got a Sandisk Mobile Ultra 16gb class 6 memory card for it. I had a Class 4 4gb card before which worked fine but i kept running out of space.
I put the card into it's included adapter and put it in my computer, successfully creating a 1.2gb ext3 partition through EaseUs partition manager. I put a new rom on the card, put it in my phone and flashed it.
The ROM (MIUI-Au ICS) worked fine but it said "unavailable" in everything to do with the sd card and isn't recognised by any file explorer. I thought it was just the ROM and installed Mildwild and a few more but they all said the same thing. All the computers recognise it fine.
Anyone know what's wrong? I've searched everywhere and found no solution.

Also now my 4gb sd card isn't being recognised. Is it my phone?

Using GParted I managed to put the Ext4 partition before my Fat32 partition and the phone certainly didn't like that. It wouldn't recognise the storage, my PC wouldn't mount the card. I had to put it in the laptop and only Ubuntu found both partitions and allowed me to re-partion correctly. If you have the ROM running, download 4EXT Recovery Control and see what that has to say. Otherwise I'm too much of a noob to help! Good luck.

[Q] N7100 Cyanogenmod - SD card woes!

Hello all ive recently installed cyanogenmod 10.1 and everything's running fine.
Bar my 64gb class 10 sd card - it's not readable by cm10.
Ive tried formatting it via CWM and its a no go. Just says error mounting external_sd then skipping then done.
When the device is on it just says "Blank SD card or unreadable filesystem"
Ive formatted the card to fat32 on my PC and it shows as fat32 with 59gb free.
However when booted it still says blank sd card and when i tap it and tap format nothing happens.
But if i boot into cwm and mount mass storage it shows up on windows as fat32 and accessible.
I havn't any idea what to do now. Everywhere i read Cyanogenmod doesnt support exFAT which my card originally was when using touchwiz.
And now that Iv'e formatted it to FAT32 and verified everything's working i cant understand why the darn thing wont work on my phone.
And i don't know what to do now.. I need the SD card and its not like its a cheap one the built in 16gb simply doesn't cut it ive got a titanium backup that has all my apps and what not that i need to restore and all i need is this silly card to be reconized. So its formatted Fat32. is there anything else i need to do -- so that android reconize it as a use-able card not just a Blank SD card that it refuses to like?
Sorry im frustrated
All help is much much appreciated
Can anyone offer advice? I've been looking around day in and out and I can't find anything ):
Any help is very much appreciated

[Q] P601 64GB sdcard unwritable

Hi folks,
I recently got a 64 GB microsd card ( class 4) for my galaxy note 10.1 SM-P601 ( build:JSS15J.P601XXUBMJ9,Baseband601DDUBMJ1).
This card works fine when I use it on my laptop but I am unable to write it on the tablet.I am able to read the data though.
Below is the list of what I have already tried and failed.
1)I have tried rebooting,remounting reinserting
2) As the default format was exFAT I reformatted it into fat32 using fat32 formatter.
3) I tried partitioning the card on laptop into 2 32gb partitions and then using it on the tablet.
4) I have tried SD card accelerators from Play store.
Once I mount the sdcard it shows TOTAL SPACE: 62.5 GB in Settings->General->Storage.When ever I try to write the card it somewhat gets unmounted and shows TOTAL SPACE :0.0 bytes.
Please suggest a solution to make it work

Have you formated it in the GN 2014?
Also, I wouldn't use a Class 4.. Just my opinion.
Also, they have some bad 64gb cards out there.. I would get a name brand 64gb class 10 from BestBuy, Staples, etc.. Format it GN 2014. If everything works, then the problem was the sd card.
I have a Sandisk Ultra 64gb Class 10 in my GN 2014 and my Note 3.. both work perfectly.
Hi gurus,
The Idea is to make the the 64 gb card (that working fine on my laptop) work on my note 10.1.
Please help .
What could be the possible reason.

As you have tried several things, can you please tell us exactly what your situation is now so we can help you.
If the card is a used one, it may have been formatted as FAT32, to work in a non-Sdxc compatible device. The Sdxc capable note may boycott the card because of violation of the specs, so reformat it to exFat.
It was similar with 4GB SD cards, which shall not exist by spec, but worked fine in Sd devices, not in Sdhc ones.
Experiencing the same

Hi maainux, I'm experiencing the same problem here, have you found any solution?
Mine is a SM-P601 / Android 4.3 / Build: JSS15J.P601UBUBMJ4 / Baseband: P601UBUBMJ1 (Fully Stock)
I tried 3 64gb micro sd card: SanDisk Ultra, Samsung, and a generic one. For both 3 the same results, as following:
1 - If I let the tablet format the card (exFAT), it can be mounted but gets suddenly unmounted when I try to write on it and shows TOTAL SPACE :0.0 bytes just like yours. I installed BTSync, when I tried to configure the sync on the tabled by selecting the sd card as the destination folder for the files, the app give a message saying it don't have permission to access that folder and gets unmounted. Tried rebooting, remounting, reinserting, and nothing change.
2 - If I format to fat32 as a logical partition using Minitool Partition Wizard, I get the same behavior as above description.
3 - If I format to fat32 as a primary partition using Minitool Partition Wizard, I can create folders but can't delete them, when I try to delete via "My Files" it says "deletion failed". I tried ES File Explorer, get the same. I was able to configure BTSync, it can copy the files from my PC folder, but when I delete some file in the PC it can't be deleted on the tablet and the BTSync app shows a message stating it can't identify the destination folder on the tablet.
I have some micro sd cards laying around, tried SanDisk 32gb, 16gb and 8gb, both 3 worked flawlessly on the tablet. I noticed the tablet format any <32gb card as fat32, and the 64gb as exFat, this make me think that was related to file system format, but it's not. Seems something related to permissions, like the KitKat 4.4 guys are experiencing. The point is I'm completely newbie on Android and have ZERO knowledge on Linux/Unix, so I have no Idea on how to solve this.
Can you guys help me?
Thanks in advance.
Hi guys

[Q] Ext4 Memory Card 64 GB cannot be formatted

Dear Brainaics
I've got an issue,
My sd card is 64 gb sandisk class 10
I was using Pro Bam android 4.4.1 on my n7100
So I formatted my memory card within the rom.. It was fat 32 or ntfs
Later I got some issues with the rom, So I installed the stock rooted rom.
Ever since that I've been getting an unsupported file system.
Format Card - It shows formatting - then unsupported file system error - This goes on and on.
So i tried mounting it in Linux Ubuntu & try to format using gparted & terminal.
My data is there.. The card reads & all.
But I can't format it.
These are all the steps i've taken, I even tried sd formatter I got somewhere from xda!
Any useful info would be greatly appreciated by me offcourse mentally.
I mean i crave for knowing the reason behind this anomaly!
Have a good day...
Cheers
Can you delete any files on the card? I had a 64gb SanDisk card that had all my data but I couldn't format it, copy files or delete files from it, either on my phone or laptop.
SanDisk replaced it for me as it had developed a fault.

Trouble with 64gb sdcard

anyone have issues with their sd card?? i have a sandisk ultra sdxc 64gb micro card. i have to format this thing about every 8 hours! insert the card and the phone will not recognize it. i take it out, format it on the pc, insert the card, format it on the phone and its fine. the next day i go to access the card and its not listed in the file manager or in the recovery. in settings i click mount sd card, phone shows "preparing SD card" then nothing. i have to do the whole format thing over again.
any ideas?? is there a firmware update i need? phone is build # 1.54.401.10
doesn't matter what rom i use, i have tried 3...phone is fairly new.
i have done root, s-off, recovery, SU, busybox, etc. phone works great! other than the sd card issue.
thanks

well i figured it out...did some sniffing around online and found a thread in the SGSIII forum. someone had a similar issue. apparently after doing a bit of additional reading, the htc one m8 does NOT like exFat cards. so while it CAN accept 64gb and 128gb cards, it doesn't really work right. to fix this i used easeus partition software, deleted the partition on the sd card, created a FAT32 one for 64gb, yes it will do it, and it works perfectly. hope this helps someone else.
I have problems with mine. I have a 128GB and haven't formatted it, and it works fine.
Thanks
