Unable to mount SD card in recovery

I am try to update my rom to Darkforest mix and I flash the kernel with no problems but when I try to install the update.zip the SD card isnt mounted and cant be mounted anyone have any ideas? I have tried some of the suggestions from other phones forums with no luck any one with a play have some insight?

What file format is your SD card? What OS are you trying to mount to? Have you tried another PC?

The card works fine on the coputer it is the phone itself that cant use it. But if I go back to a different kernel like doomlords it works fine again. Oh I also forgot to mention that I am using a Verizon play r800x if that makes a difference.

You need to use a CM7 kernel
It shouldn't do that, because it is built from the same source, and is initialized in the same way. Have you tried hotbooting my recovery image?

Ah, I see. Maybe the kernel is missing some modules that allow certain file formats. I don't think kieran included ext4 support in his kernel. Maybe NTFS too. Maybe try format it to fat32 if it isn't already just as a test.

I am using a CM7 Kernel and my SD card is formatted to Fat 32 I fifgure my phone might just be picky so I will stick to Doomkernel for now Thanks for the input though.

Error: Can't Mount external SD card!

I just bought a 64GB micro sdxc card..brand new....when I try to do ANYTHING in the lates 6.02.03 recovery, I get this error....Everything worked before I put this card in...Windows CAN access it with phone plugged in etc. I formatted it from exfat to fat 32 using Easeus Partition manager, flashed CWM and same error...so I flashed CWM to the latest (6.02.03) and same problem. I am running Wicked Rom, and have had no probs until the card was replaced, and so I did some Google searches that lead me down the path of formatting...which I had already done..but nothing...Can anyone throw me a bone here?...Im not sure what else it could be...One post said maybe the rom didnt support it?...but to me that doesnt mke sense..Thanks in Advance...Larry..P.S..I also formatted it with the option in settings on the phone which it worked fine etc...but same thing...maybe the CWM doesnt support it?..if so...maybe a link to an older one?...Im almost sure that I had the same version on my 32G card as well..

Surely someone has a 64 gb card that is functioning for these purposes?

I had similar issue before but I got it solved by formatting to FAT32 using this program: http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm
The issue I had was not because the ROM didn't support it, it was the kernel that didn't support it. I don't know if you're having similar issue or not, but if you're willing to experiment, you might try that if your ROM didn't have the stock kernel in it.
Good luck

Works in other phones?
Does it work in another phone?

[Q] 64GB SD card on CM10.1

I recently bought a 64GB SanDisk Ultra MicroSDXC card and right after I got it, I started to play around with it.
Like I knew, stock-CM10.1 doesn't support exFat, but I decided to just plug the card in and watch if the phone would suggest me to format it to compatible format. But nothing happened. So I went to Settings->Storage, and boom, force close.
I thought that maybe it was just impossible to format the card on android, so I formatted it on Windows (to fat32) but no luck. Still fc when I try to go to Storage Settings.
Next thing I tried was recovery-mode:
-fat32 in koush's touch recovery -> cannot mount external_sd
-exFat in PhilZ's "exFat compatible recovery" -> the same thing
Then I really began to think that this whole damn card wasn't supported at all. So I tried one more time.
Clean CM10.1 flash, a try with fat32 and exFat, and after that (and after 0 successful attemps) those both formats one at a time with RedPill kernel.
And nothing worked.
But one of my attempts was not very far from success: when I was on stock fresh CM10.1, I also tried Paragon's app for mounting NTFS-partition and it actually worked. The app itself confirmed that "partition was mounted and it was nearly 60GB large". But in settings and in file managers the card wasn't recognized.
The second odd thing that I noticed (actually because of a half-accident) was that if I formatted the card to fat32 BUT set the size of the partition to exactly 32GB the card was up and running perfectly.
So my questions are:
Is there someone who has 64GB sdcard working perfectly on AOSP rom? And if yes, what is your setup?
Is it some kind of bug in CM10.1/even in all AOSP-roms out there that cards over 32 gigs don't show up at all? And if it is just a bug can we expect it to be fixed in near future?
Or is Touchwiz based rom the only solution?
And if someone is asking what software I used to format the card on Windows I tried:
- fat32format
- HP USB Disk Storage Format Tool
- EASEUS Partition Master
- and of course stock Windows' format tool
And what formats I tried:
- fat32
- exFat
- NTFS
- ext4
Thanks in advance

I have the same sd card working on tw and aosp. I had to plug it into the computer and google formatting exfat 64 micro sd cards and youll find an app online. Download it to your comp and itll guide you through the rest. 10mins at max is all it should take. Hope it helps

Do you remember what aosp roms/kernels have you used while the card has been working as it should?
And do you have any clue what was that app you used to format your card?

I'll get on my computer tomorrow and tell you. But as far as ROMs and kernels, since I formatted my SD card to fat32 I use it for both tw and aosp roms from miui, to aokp, jellybam and all tw ROMs. Once your formatted properly it'll work for any ROM and kernel

Okay, good, thanks
EDIT:
Thank god, I got it working. When I downloaded and installed MiniTool Partition Wizard to my computer I noticed that somehow the whole partition of the sd card was changed to logical instead of primary. I simply formatted it to primary fat32 partition and now it works, finally.
And last but not least I have to say a big thank you.

sd card issues android 4.2+?

okay, i've tried and looked for a similar issue but so far i can't find anything related.
I have a sandisk microsd ultrahc card 16gb.
the card itself works extremely well, both in my device when using the stock / custom samsung based roms,
Didn't really notice this untill i tried out android 4.3, at wich i thought first could be a bug in the rom, the settings kept fc'ing the moment i opened up the storage part, and a com.android.media kept fc'ing the moment i attached the usb cable.
as i thought 4.3 was the culprit i flashed 4.2.2 wich also had similar issues up until the moment i removed the card from my device and restarted, everything worked smoothly afterwards.
I've tried using exfat / fat32 both with cluster of 4096 and 8192 and neither of those helped in any way. Turns out that both TWRP and CWM (yes i tried it in both) also can't seem to mount the sd-card.
Is there any workaround for this issue? or do i have to get myself another sd-card?

I think it's the ROMs man messing things up...i tried android 4.3 yesterday and my whole android directory changed like I had to go into a folder called 0/0/0/my android files. to reach my files etc couldn't mount from sdcard couldn't copy things across from pc...I just flashed back my original stock firmware and everything is good..... android 4.3 is pretty messed up..give it time to mature still very buggy

The messed up folder i should get used to thoug its because of the multiple user profiles things are getting a bit messy.
Its something they added in 4.2.2 i believe
Best way to do it is to flash the rom and afterwards copy back everything to the sdcard.
Didn't have any issues with another sd card i still had laying around but that thing even thoug class 4 doesn't get more than 1mbps transfer speed.

if the sdcard works on your pc with directly like by using an mmc adapter or sdcard to USB converter then your card is ok if it just didn't work on the phone it has to be a software issue our maybe the hardware mmc port is faulty??!

thats just it, the sd card works like a charm untill i upgrade to 4.2.2 or 4.3. however both recoveries can't mount the sd-card either.
its not one of those black ones that goes to class 10, but an ultra hdsc class 1 so might be something related to not being able to work properly with anything higher than class 10

nope....the class issue has nothing to do with software.....that's purely the job off the chip electronics/hardware.... I would say a combination of your recoveries and ROMs like I had the same issue once the custom recoveries maybe can't point to the location/ section of the memory card...try changing to different version of the recovery...maybe that could help but be sure the recovery is supported on your device...these are risky issues...so only do it at your own risk

i've tried several versions of CWM both touch and normal, also philz (yesterday but touch didn't work as it should so won't stick with that one) and TWRP but none of them could mount/find the external_sd, the only think properly working with that sd card is the stock samsung and custom roms based on stock.
(not particulary fond of TWRP, i like the layout and how it works, i just don't like the backups of that recovery, can't copy them to my computer, the extensions keep giving me an error and they are located on the phone's storage)
the sd card couldn't be found in my sensation xe neither i remembered just now after i stopped using the 4.0 stock rom and switched to custom roms, at the time i didn't really see a connection and thought my sd card just didn't want to work properly in my sensation anymore, But having the same issues, and using another sd-card in the phone worked again. Used the ultra sd card in my tabled and because i didn't use that one anymore and someone in my family needed a 16gb one for tomtom europe i gave my good one away )
gonna get myself a new sd-card this afternoon as the 8gb i had laying around isn't getting higher transfer speeds then 1mbps at most even if its a class 4. a shop nearby has a class 10, 16gb for 13 euro's so reckon thats not a bad deal, might even go for the class 10 32gb for 26 euro's if they have it in stock.

I have a 64gig card and had similar problems. With phils recovery it only works when formatted fat32. Think that exfat is not supported. With stock kernel it mounts exfat with any other kernel i tried it would only mount fat32. I think samsung kernel has support for exfat and others dont. So it might not be adroid related but kernel related.

weird thing is though, even when formatted to fat32 and not exfat, android 4.2 and 4.3 will not recognise my card, also the recoveries i only get an error when i want to mount my sd-card
my tablet which is running an aosp version of android 4.0 or 4.1 (can't quite remember) could handle the sd-card just fine, while both my phones have issues with it.
solved it by buying myself a new sd card, ^^ now i can at least safely backup to my external card instead of the internal memory.

[Q] 64Gb memory cards

So after research before I post I found out thet the 64 cards use exfat and android does not support that, rather it supports fat32, after trying different software I cannot get it to work in my phone (sgs 4) running wicked rom. I have tried to format it several times and it will work in my camera just not phone so the card is fine. Is there a easy way and hopefully free way to get a 64gb card to work in our phone, as this would be a one time use. So any help is welcome, fyi I tried ease use partition master free, and also what came with win8 but windows pushes ntfs or exfat, no option to run fat32, one more thing there is no issues losing files the card is blank.
Thanks Rob

Try fat32 format: http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm

Out of the box the S4 support exFat.
I have a 64GB card exFAT format running in Infamous S4 ROM but with Infamous kernel. You'll need to find a T-mobile base kernel for your ROM. If you want to format to FAT32 there's a lot of free program to do it.

Thanks for the help. One other question, I remember with my s2 and even s3 (at first) kernals were separate from roms now it seems you cant find a stand alone kernals. I just looked at forum and everything is rom/kernel combo, so I guess it would be hard to run infamous kernel with a wicked rom. Both are great but I just have a liking to the wicked (rom) at the moment. Kernal is to far back end for me to know the difference from one to another. Although I I had infamous a while back, before sd card.

1) Install a Linux distribution to your computer.
2) Run Gparted.
3) Format SD card to Fat32.

The kernels are in the Original Development section along with a few other AOSP ROMs.

+1 on this. I don't know why everyone seems to think formatting in FAT32 is bad. We all ran FAT32 on our 64GB hard drives back in the day. Even if you have a ROM/Kernel that will read exFat, FAT32 is a better choice for compatibility with recoveries and with other devices.
