[Q] Can't format my sd card!

So about a week ago I downloaded new version of icecream tosti's ICS rom (v0.6) and booted into CWM to mount my sd card and move the zip file over. I noticed that it was taking longer time to move the file than it usually does but I let the process finish. I unmounted the card and went to install the zip from sd card but couldn't find it. I tried to move the file again and again but couldn't get it to copy the file onto the sd card. I tried moving files from the sd card onto the computer but that was not possible either. It wouldn't show me errors and complete the moving process but it actually didn't move anything. I thought there was something wrong with the sd card so I tried formatting it... no success!
I have used easues partition manager, mini tool partition manager, hp sd card utility, panasoic sd card formatter, tried formatting it through windows native options, used disk management, even tried formatting it through CWM but i kept on getting the same error, can't format. I was placing the micro sd card in a usb card reader and sd card reader in order to format it through computer. I have also tried using different computers but that didn't solve the issue. The problem is that every time I try to install a rom it reverts back to an older revision of the rom with old settings that I set before. It seems to me some how the sd card is locked in a previous state and it is write protected and won't let me format it.
Does anyone have any ideas on how I can solve my problem or does this mean the sd card is gone and I have to buy a new one?

I have exactly the same problem after using NexusHD2-ICS-4.0.3-CM9 V1.3. It seems this sd card was frozen, nothing on it can be changed. If I copy a file to it on computer, it shows copy successful, but that file cannot be read, and if refresh it shows nothing have changed in the SD card.
Anyone have any idea about this?
I have three broken micro sd cards now, two from WP7 and this one from ICS.

I waited a couple of weeks for someone to answer on this forum and tried all methods possible to format the sd card or revive it somehow but no luck so just recently purchased a new sandisk class 4 sd card hopefully this one doesn't go bad either. I just wish I knew why it was happening so I don't repeat the process again and end up damaging the card.

Have you tried to format with MAGLDR and after it on windows 7 pc ?

I did that, also followed this post:
http://forum.xda-developers.com/showthread.php?t=1283232
Contents on this sd card just refuse to change.

is there a solution to this coz im having the same problem and cant find a way to fix this

you can do it by this software's :
HDD Low Level Format Tool
MiniTool Partition Wizard
EASEUS Partition Master
Partition Wizard Home Edition
.
.
.
.
but i dont know how create swap and ext4 partitions on sd .

This happen because you formatted the card on the phone. I never recommend to format on the phone the cards but on PC. Try the application I posted on computer with FAT32 in 32768 unit size.

failed to mount /sdcard

Hi guys, i know this has come up on here before and i've searched through all the threads but found only a lot of information which is of no use at all.
Ok heres the info on my phone:
HSPL 2.08
Task 29ned
2.15.50.14 Radio
CustomRUU
Magdlr
CWM and also tried TWRP
I've used windows format from recovery (usb mass storage) and also minitool partition starting with fat32 and 32kb sectors then ext3 partition but on mounting it only returns the following:
E: failed to mount /sdcard (Invalid Argument)
Error mounting /sdcard
so far tried fat32, ntfs, ext2, ext3 out of sheer desperation
Any help would be muchly appreciated but i'm assuming it might be the sdcard at fault i really don't know.
Thanks in advance.

Hi Dan
In minitool, did you set the primary/logical box to primary?
Why ext3?
Also what rom did you install, and what install method?

Thanks for your reply, yes both were set to primary, ext3 as that what lots of threads on here advised. Formatted to fat32 first. I can see it on my pc but can't mount it on the phone? Any ideas?
No rom on the phone yet as i can't get the zip files to be recognised as the sdcard can't mount so you can see my problem now.
Am now getting a new error message saying:
E: Unable to write to ums lunfile (No such file or directory)
Thanks
Dan

Hi Dan, best to start afresh with your card. Use this https://www.sdcard.org/downloads/formatter_4/ to format it to fat32, and see if it shows up then.
I don't know of any latest roms using ext3, most use an ext4 partition on the sd card
Anyway, report back

Ok i'm slowly getting somewhere, twrp didn't work, minitool didn't work, cwm didn't work so then i tried the new version of twrp and formatted it on the sdcard which can now mount sdcard on twrp.
The issue i'm having now is that adb doesn't list it under devices. I'm having to use adb sideload as because its been formatted on the phone it can't be seen on the pc? Not sure if thats as i don't have the hd2 drivers on the pc but its got hd2 toolkit installed. Either way i now don't have any way of installing from the rom zips I have.
Thanks
Dan

Hi Dan, I don't think Android Debug Bridge will work if you do not yet have android on your phone (unless it works from twrp). It seems you have magldr installed, can you use usb mass storage to transfer your rom to phone?
Also I do highly recommend using the sd formatter i linked to earlier, but i assume you do not have a card reader, hence doing all from phone.
Best of luck

I had this problem to fix
i installed everything then formatted card to fat32 using mini partition wizard and then did EXt4 and swap partition from Cwm Recovery and it worked just fine

Just incase anyone has the same problem i had with the never ending unable to mount sdcard problem.
What this turned out to be was cwm would format the card but only a certain area, then if you format with windows it will again only format a certain area that it see with its own file system. Then minitools would have a strange arrangement of differing file systems and changing this by usb connection through magdlr kept creating these problems.
I was trying to use adb to connect the phone to the pc through usb drivers but in the end it simply wasn't worth the effort.
First I went over cwm with the latest version of twrp.
Then I went out to buy a new sdcard simply to get a sdcard to microsd card tool.
Reformat the sdcard (with minitool partition) once in the pc (using the microsd to sdcard tool) to fat32 or fat32 with an ext4 partition if yr doing nand and dataext. Both partitions need to be primary and make sure there are no other partitions on the card this may take a few goes as sometimes you get a random partition or I did anyway.
Then put your rom files on the sdcard using the pc.
Remove sdcard from pc and install in phone.
Boot phone into magldr and choose recovery and this will take you into twrp and simply choose install and find the rom file you want to install.
Don't worry if you have any problems in the rom install you can always go back into twrp and wipe the system which is the rom.
Hope that helps anyone who was experiencing the same issues.

Alternate workaround
I had the same problem others have above. I wound up using a different workaround, and was able to do it with just the phone, a USB cable, and a Windows 7 PC. No SD adapter was needed and there was no need to remove the microSD card from the phone.
I took a stock WinMo 6.5 TMOUS HD2, installed Black LK and TWRP and cleared everything (cache, etc.). Then I used Black LK (very similar to cLK) to re-partition the internal storage to accept my new Android ROM. All I needed at this point was to install the ROM. I tried to copy my Android ROM to a microSD card I had in another phone and then bring it over, but TWRP was unable to read the card. It also couldn't mount the card via USB.
I was able to use TWRP to format the microSD. Then TWRP was able to USB Mount the microSD, but when my PC dectected it, I received a popup indicating that I needed to format the SD before Windows could use it. I said "yes", and allowed Windows to format the card as one big FAT32 partition. It took a few minutes, during which I was a little nervous as there was no progress meter or anything else on either the phone or the PC to indicate it was working. But once it finished, Windows was finally able to access the microSD card and copy the .zip file for the ROM. Once that was complete, I told Windows to eject the microSD, then un-mounted it in TWRP. And, finally, TWRP was able to see the ROM file and install it to NAND from the microSD.
Anyway, thought I'd post it up in case anybody else runs into this and doesn't have a card reader or adapter.

first backup any data you have on your sd card
connect sd card to pc via card reader
remove all partitions with minitool (google it) and create a new partition of fat32 and format it with minitool
next boot up your phone with the sd card in
goto
settings

unmount sd card
erase/format sd card
now go into cwm - you sd card will now be mountable
you can then copy any backups back to sd card
An odin connection does not require an sd card - if odin is not connected you either dont have the usb drivers installed or you have a faulty usb cable/port

flash stock rom via odin - it doesnt require an sd card
if your odin doesnt show a connection under com id then you havent installed the usb drivers
you can format your sd on a pc via a card reader with mini tool as already explained

How to format SD card in fat32 or ntfs format?

hello everyone, i am using samsung sm-g900h with marshmallow in it and i have rooted my phone with twrp recovery. The phone is working very fine but i dont know from last 2 weeks i am not able to copy , paste , rename , move or delete any file from my external memory card using Es file explorer . i googled about that and did cmd things and disk management things too to format sd card using laptop but it always show RAW as format not NTFS or FAT32. I then deleted ( unallocated) the SD card and inserted it back on phone and formatted it from there and its showing everything fine... but while copying files from laptop it stops at random file for so many minutes and when i open the folder i see some coding languages files and folders in it like some virus or so...
Is there any solution of it or i have to buy new sdcard ?

Try putting the card into a USB reader in your PC, and use a program called "MiniTool Partition Wizard Free", delete all the partitions on the MicroSD card, create a new Primary partition, then format to FAT32, see if that fixes it for your phone

No format on SD card after marshmallow upgrade

Hi, I'm trying to find how to solve this problem with no success.
I got Bliss Rom with marshmallow and i formatted my sd card as an extension of internal memory. Something that marshmallow allows.
I got back to stock system and recovery in order to upgrade officially from stock but, the system doesn't recognize the format of my sd card, suggesting to give it a format.
After that, system keeps on not recognize my sd card and I'm stuck.
Do I have to format it taking it out and accessing via a cardreader to manage file system or there's a way to solve this?
Thank you in advance...

Try to format it with a computer

No success. There are 2 partitions that cannot be modified. I'm stuck...:crying:

I just [RESOLVED] an issue after inserting a brand new SanDisk 128GB microSDXC sd card.
The Honor 5X will format the blasted thing to exFAT which refuses to open up in my Windows 8.1 Laptop to access folders and the like. A try to format to FAT32 did not have that available either. (Windows only showed NTFS/(default) exFAT)
So what i did was grab this SanDisk formatter
Code:
http://www.verbatim.com/includes/binary_details.php3?show=1&id=840
and in an instant my formerly exFAT transformed to the more easily PC accessible FAT32!
Now it shows up perfectly whenever plugged into any PC via USB and you can feel free to reach your SD Card contents manually to your hearts content.
No need for Huawei's (in my opinion buggy) HiSuite which i find sorely lacking and too much wasted time with Import/Export stuff.
Hope this helps someone, anyone who thinks that they absolutely must use Honor's/Marshmallow's own formatting to exFAT.
