SD card not being detected

When I tried to access an app that was installed on SD, my phone locked up. Upon a reboot I no longer have access to the card, all the apps' shortcuts are broken and all the options like mount SD card, format SD card are greyed out. Also when I connect the use cable there is no option to mount as disk drive anymore. I've rebooted, tried removing the card etc but no luck. Anyone else had this? I can't find my micro SD card adapter right now so I cart try it in my pc.

Did you try running checkdisk from windows to repair it?

No cos I can't mount it in Windows

Try repartitioning your sd card. Could be a corrupt ext partition, or your sd is completely screwed.

I'll have to find my adapter

Sounds like a bigger problem than a broken ext if nothing can read/mount the sd card. Might be the end of your sd cards life im afraid

I've only had it about 2 months.....get what you pay for I suppose (click). Anyway still no luck with the adapter so I'll see if anyone's got one at work tomorrow.

OK, I found my adapter (and my old microSD card hiding within), windows has no problems seeing the 16gb card and my old (original 4gb) card has the same problem in the phone. For good measure I did a chkdsk on the card.
What are my options?

I've performed a full reset and still got the problem. Anyone got any suggestions?

anyone? I'm thinking it's a desire hardware fault.

any help? cheers

A number of us have had failed SD cards. In my case, Windows could see it well enough to copy most of the data off but failed to reformat it. I suggest you try to copy the data somewhere safe and then reformat in Windows. If the reformat works it's probably a hardware issue. If the reformat doesn't work it's probably the card.
I'm sure others will have different views!

Yeah but it's same with both my cards. I'll give it a go anyway cheers.

The one that came with the phone .. ( 8GB Class 2 ) came up with with a read only error last week ...
The card was dead.
I got a 8GB card class 6... used app brain .. and restored all my apps fine... etc
fab.. phones faster .. no problems

After inserting my old card again I now get the dreaded -
SD card damaged. You may have to reformat it.
Of course when you follow the wizard to format it, it doesn't seem to format it. I did try a full format in Windows earlier, no luck.

Just to help anyone who stumbles over this thread in search of an answer, I've had to send it away for repair, it appears to be a hardware fault. 2-3 weeks.

Sdcard cannot mount!

Today I installed the rom called Pirate rum. But now I can't mount my SD card. I tried booting into recovery to flash another rom. But not even clockwork can mount it.
I have tried using a cardreader in my computer. It reads the card fine.
I then backed up files and formatted the card, but it's still unreadable.
Also tried another card.
Are there anyone who might be able to help?

Same thing happened to me a few month ago. Formated the card in both windows and ubuntu. Still couldnt mount untill i formated it using a program in windows. Took like 40 min to format it. I forgot what its called and im not home right now but i have it instaled on my pc. Ill tell you when i get home

does the device read your sim card? it sounds like a usb brck if, its happening with more than one card

It reads the sim card. It's the SD card which doesn't work...
Also tried with amon ra.

I got it!
It was usb bricked. I remembered a tutorial from modaco, and fixed it.
Thanks Androhero. (For making me think it could be that. )

sd card not detected on phone or pc

Hey guys,
A friend of mine gave me his desire to root and flash a rom, while I was partitioning the SD card - everything went well (I used a windows app to create the partitions while the desire was plugged in in USB mode.
All went well until I disconnected it after the process was complete - now the phone nor PC detects the card.
What are my options?
Cheers

You're using a usb card reader on your pc or whilst in your phone (plugged in via cable)?

Using a card reader with the microsd adapter

Use gparted in the reader to see what you can see.

Yup. Try that

OK this is unusual, I managed to boot into recovery and mount the SD and sd-ext without any issue - I even booted into a custom rom I flashed from SD, but I still can't get the phone to detect it when booted.

Like rootSU said, try it with GParted in your pc and see if it can find it. If so, format it all and re-partition it.

OK I managed to get it fixed - seemed like an issue with the partition - I used recovery to mount USB storage (it worked) and I re partitioned it and it is now functioning correctly.
Cheers guys and thanks a lot everyone for their inputs !

What did you repartition with?

I used MiniTool Partition Wizard Home Edition ! very nifty app !

You're very lucky, its an awful app. I feel so strongly about it, I even put it in my signature (incase you missed it).
I bet its because you used minitool that it broke in the first place.

wow, that is rather fine print haha, I hadn't seen that there - I too have a feeling it broke cause of the app, but it did manage to fix it - hopefully I won't have to go through this again - if I have to I'll use gparted - Lesson Learnt !

I'll make it bigger

Way aye, but I dont want it to take over other things

hi. i've faced the same problem too with my galaxy mini.
but, when i mount usb storage it said that "unable to write to umslunfile (no such file or directory)" . and when i format sd card it said "error mounting sd card, skipping format".
my sd card cant detected by any phone or laptop. cant be formatted or mounted. what to do? please help me. there's so much important things there.

Hi there,
Ive been through the same issue just the other day and after read and try lots of things, i had to do something stupid but has worked for me... If you have a digital camera laying around, put your sd card and camera will do its thing..will prompt you asking if you want the sd to be formated... Thats it sd alive and hoping to receive runny rom in my case
hope this works for more people. Take care. Peace.

Cannot copy anything to my sd card

Hello,
i recently bought a new sandisk ultra class 6 8gb micro sd card for my phone..but i can't copy anything to it....the drive shows in computer but when i try to copy something to it, it says "An error has occured. The destination you specified does not exist.It might be in an offline network location or an empty CD or DVD drive. Check the location and try again. "
Also, i received one adapter with it...through which i can copy stuff onto the memory card but the problem is that i can't copy anything on it directly when it is in my phone , i also formatted it twice but still no luckkkkkk
Do i have to use the adapter at all times?? is there any way so that i don't have to use the adapter??
Please Help.

There is no problem with your memory card, your phone software/hardware may has some problem.

do you mean i should format in CWM or did i do format in CWM???
and also my phone wasn't rooted before....i mean when i used both of those memory cards....

its just doesnt work, there is a compatibility problem with some sd cards in wfs, you have to buy another brand of sd card it will probably fix your problem, but i think you should try the card before buying it in order to make sure there is no compatibility problem.

I had similar problem. I formatted my new class 10 with cwm in my phone, then used minitool to partition to ext4.

[Q] Why can't I create my EXT4 Partition?

As title says , im unable to create the EXT4 partition on my SD Card. I have 2 SD Cards one 8GB class 2 , and other one 32GB class 10. Normally i use my 8GB class 2 card but I wanted to change it to the bigger one because the 8GB is not enough for me . I've 7GB Fat32 and 1GB EXT4 on it working perfectly , i partitioned it in the 4EXT recovery. Although , I wanted to change it with my other 32GB card. Everything seems to be perfect, i supposed to create the 1GB EXT4 again but... after partitioning i go to "info" it doesnt show me the EXT4 partition unfortunately ...just saying that my ext is not formatted , but i cant format it because i didnt create it on my 8GB SD Card it shows that i have the ext4 partition, but on the 32GB it doesnt... and the problem is i cant boot up any ROM with it could anyone help me with this? I really want to use the 32GB card but i cant for now

Hey Chromium Yeah so, I tried to partition the SD Card with Gparted but unfortunately , when I booted it up , I cant see my SD Card info.. Only the PC Partitions. Could the problem be that , my phone is in 4ext recovery?? I did turn on the Disk Drive from recoery but Gparted still cant see it. I tried several times "Search for devices" in Gparted but didnt help. Any idea bro? I never did it with the Gparted , i always partitioned my SD card by recovieres or Minitool Partition so im not used to it

Did you follow the partition instructions for gparted here?

Of course man ... But on the step that I should see the PC partitions along with the SD Card , There is no SD Card there are 3 ntfs partitions and the Unallocated Space one. I don't know what's the problem really

Yeah, might be the PC's fault. Try another one.

The fault was the laptop I tried on my other PC and it worked (I could see the partitions )i succesfully formated it by Gparted , but in phones recovery in the "Info" option the SD-EXT is still not formatted .. 30gb is fat32 , 1gb sd-ext and 30mb swap (I don't need it , but I really want to use this SD card so I just did everything like in the guide even if I wouldn't need it). I dont know If the problem is the SD card itself or..

Try without swap, you don't need it. It should be removed from the guide
Both partitions primary, FAT32 first (on the left) and the ext4 second (on the right)
What ROM are you trying it with? Have you checked whether apps are actually installing to the partition with something like DiskUsage?

- Have you tried partitioning the card completely from scratch again, max 2GB ext4, no swap?
- Does 4EXT recovery see and check that the partitions are aligned?
- Tried installing a different ROM which requires an sd-ext partition just to try something else and get it booting?
If you've tried all the steps, could be a bad card though unlikely in my experience.
