[Q] [HELP] SD card can't mount upon flashing LeeDroid 2.3d

Greets people,
I have been using the LeeDroid roms for a while now, for some reason i like sense UI but i have encountered a problem when installing LeeDroid 2.3d from 2.3b. I made sure i NANDROID'd beforehand (I may be new but i saw that was important) but anyway, my SD card will not mount when i flash with or without wiping data and cache...I have a Kingston 16GB class 4 or 6 (i can't remember lol) and was using no A2SD+ on both versions.
Thanks in advance

Scan your SD card for errors, that solves it most of the time. Do this with a cardreader or from within the recovery.

alright, i will try that mate. If i copied everything off the SD card and re-formatted it as FAT32 will that do as well if there are any errors?

[Q] Galaxy Y Recovery problem with SD Card.

Hey guys,
So, having a little problem with my dad's Galaxy Y. I tried to root the device this evening and when I went to the stock recovery and chose "Update from SD card" it gave me an error.
E:Could not mount /sdcard No such file or folder exists.
This happened with a Class 4 Kingston 4Gig SD card.
However, when I used another SD card(1 Gigabyte-Class4 Kingston), it worked perfectly. However, I want to use my 4 Gig card for custom ROMs and link2SD. Is there any way I can keep using my 4 Gig card and NOT get that Error?
Thanks.
PS. By the way, the SD card is working fine, and it's working in the phone OS, Windows, Mac OS X SL and Linux.

Reformat your SD Card using MiniTool Partition Wizard and make sure the file system is Fat32. Report back after you tried this step.

Done and done, still the same error. :/

I remember having the same problem with a Kingston SDHC Card, repartitioning fixed it.
Try re-moving the card when in recovery and then re-insert it and try again. If that'll not work, re-flash it to stock firmware then root the device. Re-flashing won't take that much time, between 43-46 seconds only. Everything you need is in my Samsung Galaxy Young for Dummies guide, under ROM and Kernel Flashing.

Simply format the sd card in "full" i.e. Full format, not quick format. Fat32.
Prob solved.

Try mini tool this way
1. Delete the entire partition
2.Now create new partition
3. First one for links2sd 512mb ext 3
4.remaining space for the primary memory fat32
5. Now copy your update. Zip to the card. Try again

Guys, I know how to format an SD card. Been a Linux geek for seven years now. On the topic, I think there was a problem with the previous repartition. Formatted and repartitioned it with Linux.
Solved. Thanks for the help. Cheers!

[Q] 64GB SD card unformattable in AOSP & AOKP

I have had my GS3 for a little over a month, rooted and had no issues, I installed another rom with no issue. Unfortunately when I tried to install a CM10 or AOKP rom, each say my ext sd card is damaged and needs to be formatted. I try to format, but it hangs and then just quits without completing the task.
I have tried formatting to fat32 on my PC, downloaded EaseUS Disk utility to format, but none seem to work. When I restore back into the previous rom, it still says damaged and then I can format and start over only in that non AOSP/AOKP rom.
I boot into recovery when the AOSP/AOKP roms are loaded and it wont even mount or format in recovery either.
Any ideas?

I think I read somewhere that in CM10/AOKP that it won't read/understand exFat very well.
So, formatting to Fat32 is definitely the way to go.
When I used some other programs it would say the same thing... that my card was damaged and had to be fixed.
I had a heck of a time finding a program that would do it for me on my 64gb sdxc SanDisk card!
But I found a free one called GUI Fat 32 Format that actually worked.
Click this link and it will start to download:
http://www.ridgecrop.demon.co.uk/guiformat.exe
It didn't work immediately, for me at first, but after a few tries it actually worked very well.
I think that once you get it into Fat32 all of your problems will go away. Hope so anyway.:cyclops:
Let us know if it works!

This seems to have corrected the issue, finally

I had a similar issue... I flashed an AOSP ROM on my phone n it corrupted my sd card and wouldn't format. before formatting I went back to a touchwiz ROM and it still said it was a bad sd card and needed to format I ended up formatting my card in my phone and lost all my data. I put music on my sd card and removed the sd card from my phone before flashing another AOSP ROM. After I installed another AOSP ROM I re-inserted the sd card and it again said it was bad and needed to be reformatted...
So my question is...How can you use a 64gb sd card on an AOSP ROM...I'm back on touchwiz for now. Sd card works fine.
Does formatting the sd card in your phone format it to exfat and not fat32?

Wait, so you're saying that AOKP/CM10 don't have the necessary drivers to handle exFAT formatted sd cards?
Do you remember where/how you came upon this information? Was this issue particular to 64gb SDXC cards vs smaller SDHC cards or maybe to certain classes of cards?
I find this shocking, but I can't say it isn't unfounded.
I have a 64gb uhs-1 sandisk card coming from newegg in a few days, so I'm obviously concerned.
Any insight you could provide is greatly appreciated!

Hey guys... after doing some fooling around I've found out some (useful) information for people with 64 gb sd cards...
1. When you format an sd card while its inside your phone it will format it to exFat.... which is fine if you plan on only staying on TW ROMs. This format is not compatible with TWRP Recovery and has given me issues (causing me to loose all my data on my card) just by flashing an AOSP ROM
2. If you use the program posted in the second post(thanks iomega311) you can format your sd card to Fat32 and it will now work on TW ROMs, TWRP, and AOSP ROMs.
Hope this helps for anyone with SD Card Questions/issues.

In my opinion... Never program sd cards on phone... Always use a computer. Especially if you want it done right!!!!

CM 10 which all the AOSP roms are based off does not support exFAT since it is a proprietary format and they don't want any legal trouble. The best way to format a 64GB gard is with GUI formatter

What allocation size did you guys use? Just got my 64GB SDXC and need to format it so that I can use it on CM10.

[Q] Strange SD card problem

Well, I have a class 10 16 gb micro sd car. today after installing the Increase Internal Memory mod by XtremeSilencer, I partitioned it using the Minitool partition wizard. after booting it can't recognize the sd card but detects it in cwm. So I know my sd card is alright. so I flashed the whole rom(Revoluotion HD ICS) but still it can't recognize the sd card although detected in cwm just like previous times. After then I tried a lot like formatting it,partitioning it by both CWM & Minitool from FAT32 to FAT-EXT123..every format. But nope..nothing happened. I even flashed the stock firmware.. still no respite. please help.. :crying:

[LG D855][CM 13] Issue with sd card and what ROM should I choose?

Hi everyone!
Today I upgraded from CM 12.1. something to CM 13 and got a kinda weird bug, where google play services kept crashing, so i reflashed the gapps, and got another bug where the starting presentation program (don't remeber the exact name of the program, "guided assistance" or something, the one you get at the beggining explaining how to set up your device) kept crashing, making it impossible for me to continue using the device. Decided to restore factory settings (clicking between a crash and another xD) and everything works fine, except the fact that I can't use my sd card any suggestions? Any other info needed?
Is there a marshmallow rom with a working sd card?
P.s. I just read that is a issue that the developers are aware of, but i can't find anyone complaining about this error (the sd card not working) in the xda CM13 thread
Thanks to all!

MicroSD card support in CM13 ROMs is borked - the only thing you can do is wait it out!

Im on the latest CM nightly and I have no issue with my 64GB sd card. I used the built in format option and I seem to be fine

Does the current CM nightly that you're using support exFAT out of the box? The reason for me asking this is because on the 20151207 nightly, it was still complaining that the 'SD card is corrupted'.
FAT32 support for SD cards is fine on portable storage mode but when formatted as 'internal', people are still reporting problems as well.

I got that message as well but when I formatted I got my full sd card

If that is the case, then what file system is your microSD card using currently?

From what I can tell exFAT. My transfer speed was much faster then when I had to use FAT32. Is there an app that can tell me what format my SD card is?

Soorry if this is a stupid question, but what is the built-in format? Can I use an SDXC card from another Android device (Samsung Tab S) or this a special format option found only in CM-13/Marshmallow devices?

When you put a SD card in the phone on 6.0 it will ask if you want to format it. With 6.0 you can use it as portable storage or internal memory for more room for apps and such. I use portable storage but as of the last nightly I didnt have to format my SD card. CM fixed exFAT support in their latest builds.

Hey can you tell me your SD model? And filesystem? Just plug in your pc and see in the properties settings. Can you tell me your CM build?

Little update, I flashed Cloudy 2.5 and Gabriel kernel, thanks all

I figured out the SD card problem , i couldn't fix it for nothing until i did this.
FOR ANYBODY THAT GETS STUCK AT 20% or any other sd card problem with 6.0 roms
1. Backup all files on SD card (This will delete everything on your sdcard)
2. Install minitool partition wizard on your computer
3. Inset Sd card into PC with and adapter and/or card reader (NOT WITH PHONE)
4. Remove all partitions from SD card with partition wizard (Do not reformat) Be careful to only select the SD card
5. Place SD card into phone
6. Let the phone detect SD card and try to reformat
7. chose either Internal or Portable Storage
8. Enjoy because it works perfectly for me now.
btw. im running a LG G3 D850 ATT

there was a fstab issue with external sdcards, the fix has been merge already though.
