SD card not recognized by ROMs?

Strange problem with this desire, I can access the SD card from recovery with stuff like USB-MS and flashing from SD but with stock it says the SD card isn't recognized (the options in Settings are all grayed out). With a rom that has Apps2SD like InsertCoin where some of the main apps are installed to the card it just leaves me with a blank screen on boot with the background/top bar still there.
Pretty strange desire really, when I first looked at it the problem I mentioned above was happening (it was originally on InsertCoin, worked for around 4 months before this started) so I reflashed it to stock and then had it returned to me with the owner saying that their SD was broken.
If anyone knows how to fix this it would be much appreciated as I'm as stuck as a brick wall right now :/

Explain your problem in no more than 2 sentences that actually make sense and I may be able to help you out.
Add on information such as
ROM you are/were using
Can you boot
Does PC recognise phone
Hboot (S-ON/ S-OFF)

Have you tried with another SD ? Maybe it is the SD thats broken ?

Sorry, let me dumb it down a bit:
In Amon Ra recovery it sees the SD card fine and lets me use it over USB fine too but when I boot up into a ROM it doesn't seem to find it.
Using InsertCoin/stock ROM and neither recognize it, it boots up fine and the PC can see the phone too, but since it can't mount the SD card I can't use disk drive mode :/ It's using S-OFF hboot too.

The SD is fine, it works in recovery and in my own desire but I've tried another SD card to be sure and still nothing

hmm ok try to reformat the SD card using recovery and tell me if it works

I've had/got a similar problem. I believe it's a problem with the contacts between the sd card and the 'holder' for the sd card.
Try removing the back of your phone, removing the sd card, pushing down on the metal 'holder', replacing the sd card, and rebooting.
This works for me for anything between 1 minute and a couple of days before the problem starts again.
I have no idea why the card is still accessible in recovery. If the above had no effect then please ignore!
The only solution, and it's really not useful, is to remove the sd card. I've returned my phone for repair and nothing got replaced (my guess is because the sd card is still accessible on recovery)
EDIT: No longer convinced it's the contacts as whenever my phone 'freezes' if I reboot into recovery the sd card is always accessible.
Now think it's to do with the file system/structure on the sd card becoming corrupt.
If I format the sd card as one single fat32 and keep ALL apps on the phone then I have no problems.

or your phone's sd reader chip thingy is broken somehow? if your pc can detect it, but your phone cant, it is mostly related to be more a phone problem than a sd card one.
backup all of your data on your sd to your pc, and than format it.
put it in your phone again, and if it still doesn't connect, there might be a problem

sd card issues

I have started having sd cards issues recently... (like 1 month now)..
1) i sometimes get usb brick according to 4ext ... when i boot in recovery, it says sd card can't be mounted and i need to use the usb unbrick tool (never had such issue with cwm.. maybe it's 4ext related).. often get this when i have copied big files to my sd card or i have just flashed a new rom or sometimes without doing anything special... maybe after a black screen of death)
2) when i copy files to my sd card, it sometimes takes a lot of time (at some point, progress bar remains static) or sometimes i get an error IO device error... need to unmount and remount to my pc.... and windows asking me to scan and fix
3) i often get scan and fix when connecting my htc desire to my pc...
4) i sometimes gets black screen of death and this most of the time results in "scan and fix" message by windows when i connect it to pc..
is my sd card getting old and not working well as i used too much a2sd based scripts? or is my phone sd card reader getting defective (hope it's the first one as i am getting a new class 10 card anyway soon)
how will know what is wrong? are the a2sd scripts damaging my sd card? thx for reading and waiting for your opinions and help thx

How did you partition your sd-card?

i used one of the tutorial on xda... (the one using gparted) and i have been using this partitioned sd card for about 2 years now with no major issues... it's recently that it started to show issues.

Try repartitioning it. If it's still faulty, then change it.

ok thx will try that... but how to know whether it's my htc desire sd reader which is faulty or it's the sd card?

Try using another card afterwards. If it's the same, then it's a reader fault.

haven't try repartitioning my sd card yet.. i have too much stuff to backup.. anyway is there a cause for usb brick/io errors? i got a usb brick today.. can't copy files and 4ext recovery can't mount sd card... i never got that before

[Q] SD card unexpectedly removed / Damaged SD card

Hello, I am on an HTC One V running PACman ROM 15.3, with the kernel JmzPrimoC+.
I started having this problem a couple weeks ago. It would randomly unmount my SD card saying 'SD card unexpectedly removed'.
This started to happen more and more often until it would say that as soon as I put the SD card in.
I did a factory reset, which helped for about 5 minutes before it started happening again. Now, more recently, it started saying 'Damaged SD card. SD card is damaged. Try reformatting it.'
I put it in my computer (which doesn't show anything wrong with it), and did a full format. It didn't help at all.
This problem is happening with both my regularly used SD card (SanDisk Ultra® microSDHC™ UHS-I 32 GB (the red and grey one)), and my ordinary SD card (8 GB class 4 Kingston).
I don't think this can be a hardware problem because when I boot to recovery, TWRP recognizes it perfectly.
But I don't either see how its a software problem, because a factory reset should have helped...
Please help me, any help will be greatly appreciated.

Maybe its a bug in the rom?

Hhmmm...
Good idea. What other ROMs work with JmzPrimoC+ kernel? AOKP?

OK, update, now TWRP won't read the card! Either card!
Now I'm getting really nervous...
Does this mean it must be hardware?
Is there ANYTHING I can do now?
Please help!

Wow, I screwed up really bad.
I was gonna use TWRP to flash a new rom, so I did a factory reset, and then started flashing the rom.
But in middle of flashing the rom it was interrupted. So I rebooted, rereset, and then I realized... it's not reading my card.
I can boot to bootloader and recovery, but that's it. No OS. I'm screwed.
Is there ANYTHING I can do?
Is it possible to flash a rom over USB? Or SOMEHOW get my card working again?

Just enter recovery and use adb sideload to flash a ROM.

But I need an SD card in order to use ADB sideload!
It fails every time because
Code:
E:Unable to mount /sdcard
Is there ANY way to do this without an SD card?

OK, I was able to do it following this guide.
I flashed the latest version of PACman. Still rejecting my SD card though.
I guess it's a hardware issue. Too bad my warranty is void from bootloader unlock :\

Try to partition SD Card in recovery
I am facing same issue and I came across this thread while looking for solution. Here is what I tried. That resolved issue for five minutes and then damn! same issue again but someone can find possible fix using the info here.
HTC One V rooted, currently running MIUI 3.1.2 with JB 4.1.2
Sandisk 8 GB SD Card.
Firmware CWM Recovery
I was facing same issue even before I rooted my phone while Original HTC ICS 4.0 Firmware was installed. MY observation is the problem starts few months after you start using SD Card. (Insert a new SD card in your phone, it will work fine for days / months and then will start giving same error.
While I tried thousand time to remove SD card, clean slot, clean card and reinsert, it did not work. May be worked just once for few seconds. When I tried to connect phone to PC and browse SD card contents, the card was not detected.
Booted to recovery, tried to format card, not detected. Tried to mount SD card, not detected. Then tried to partition SD card in Advanced options in recovery. The available options are 128MB, 256MB, 512MB, 1024MB, 2048MB and 4096MB. Since my SD card is 8 GB, chose the largest option. Now got an option to choose SWAP partition size. Chose 256 MB. Next chose option fix permissions, you have to wait until you see message permissions fixed message on screen.
Now rebooted phone, and voila! It worked!! SD card with 3.94GB memory is detected. But what happened to my rest of 4 GB?
Tried many apps to manage SD card from Play store. Using an app called APart, was able to delete partitions on SD card and create new ones. It worked for few minutes and then again I got SD card unexpectedly removed message.
Does this info makes any sense? I am not a developer and do not know much into phones but someone who know might be able to help. Buying a new SD card is not an option here because its going to work temporarily.

Have you tried formatting the SD card with your computer?

Help - not reading micro sd card

I have a PNY a 64gb class 10 had this card since the phone came out,
I noticed that you could update to marshmallow by LG Bridge, so i did so, everything went smooth, however i noticed everything used to be saved on my sd card then was saved to my phone and its not reading my sd card at all.
Ive formatted the sd card through my phone by storage-sd card-settings-format- while im doing this at 20% it will say sd card is ejected but then proceeds and says its been formatted correctly.
However the phone will read the sd card only in SETTINGS-STORAGE, it will read the files on the sd card, how ever if i try and play music/movies it will not read it through my apps like mx player/poweramp.
Apps like app manger 3 - which i use to transfer apps to sd card will not read my sd card at all.
Ive tried and formatted the sd card through my phone only around 5 times and still the same problem.
any help

i would check the permission thing just to make sure.. here is a how guide for that
i dont know what you can do more than that,you could maybe try to check another microsd to check if it didnt ruined the file system on it or(or simply if the sd you have is broken) or to if it is really a OS issue...
but as it seems for now a lot of people having problem with the sd part of marshmallow...

ive tried to do permissions but it wont allow to change to sd card,
Ive reloaded phone and before it comes onto my home screen says mount my sd card, ive gone into storage - sd card- mount, restarted phone but again the same issue.
When im in camera mode the phone allows me to select where my photos will be saved (onto sd card), i can go into settings_sd card and read everything onto sd card, however its just moving apps onto sd card it will not allow.
Ive read online saying marshmallow may only allow apps to be saved on internal memory now due to previous versions off OS- was a problem with viruses being attached on apps which were saved onto sd card- was the main problem. Could it be this?, marshmallow doesn't allow this.

Use TWRP to format, that was the only solution to get my 128 GB sd card working after update again. The integrated format function always tell me success while notification said card damaged. After formatting with TWRP everything worked again
Edit: Are you sure you flashed correct patched kernel as this can disable vfat reading? Look here in forums, there is a thread about different version names for different countries (e.g. German V20a is polish version V20b)
