I recently posted a thread about an issue I'm having with pics being visible on my sd. http://forum.xda-developers.com/showthread.php?t=934080
I've determined it's the partitioning that's causing this. I'm starting a new thread cause I'm determined to find the answer.
I put a new card in without partitioning and it's working fine. Why aren't my cards working after I partition them. This has happened to several cards now.
To partition the cards I'm using RA and going to partition sd and then doing ext2 to ext3. And that's it.
I hope someone has some answers. I have a lot of apps and would like to use apps2sd.

Hello.
I have bought a new SD Card (kingston 16gb Class4).
I had a lot of problems with ext3 make. By Gparted it have errors.
I have readed this topic.
Can I repair my SD Card?
Sry for my english.
How are you connecting the card? Via a card reader or still in the phone? If it's still in the phone make sure you are in recovery and not booted in to android.
I made it by card reader. Formatting and partitioning by recovery - errors.
Have you tried erasing all the partitions and creating them again? What happens if you click the 'Repair' button?
I've always done my partitioning with my card in the phone, connected to my PC while in recovery and used Minitool Partition Wizard for Windows (this software was suggested in a thread I read a while ago) and never had any problems.
There is also the possibility of the card having a hardware problem, so you might need to swap it under warranty.
yes, first i have erased all partitions (deleted)
On repair ext - error, fat32 works fine.
first make an extended partition for your fat32 and inside that a primary fat32.
The unallocated space make it ext3

shouldn't both partitions be primary (no extended ones)?
erase everything 1st keep it unformatted then create fat32 primary then ext primary (optional linuxs swap) this is what i have done when installed miui rom data2ext
i suggest you dont use that card reader try through the cell....
I have tried a lot of methods - ext still no works.

Where did you get the card from?
Stupid question but two of my friends bought cheap (fake) cards from eBay and both had problems with them, either the card kept losing data or they go errors loading from the card due to the poor quality. In which case you need to spend a little more and get a proper card from amazon on a high street retailer.
If not then as suggested use try formatting and partitioning the card through the recovery on your phone, most of the up-to-date recoveries can do this and it's the easiest way to get the card ass needed for a2sd etc. if it still doesn't work then take the card back it's probably faulty.
I bought this card too and even though I had no issues formatting the card I do have speed issues with it. I've been in contact with Kingston and they're looking into it. My writing speed is 1.6Mb/s....
But now a tip for you, I couldn't use Gparted since it's Live CD wont start my monitors. So I downloaded Easeus Partition Master. Very easy to use and it worked perfect.
Start with your Fat32 partition and then your Ext partition.
You can find the program here: http://download.cnet.com/Easeus-Partition-Master-Home-Edition/3000-2248_4-10863346.html

Hi Again,
Right so i had a look at what i needed to do to install the Leedroid ROM. I had to partition my card. Which is a 2GB. ut when i go onto GParted it only shows the normal memory not the other 1GB which i had partitioned before. Is it susposed to be hidden or something? ive tried formatting the card. it hasnt worked. Any ideas on why this isnt working?
Thanks in advance
I had the same problem after flashing that rom. May be a coincidence but wouldn' see sd cards. Turned out to be hardware fault and had to get back to stock and return. Try another sd card of reformatting. A couple of my cards became corrupt and needed reformatting. Seems ODD
Please use the Q&A Forum for questions Thanks
Moving to Q&A
How did you partition it initially, and what do you mean by 'normal memory'?
Assuming you created a 1GB FAT and and a 1GB EXT partition, do you mean the EXT partition is missing? It may be that the partition table is corrupt, try running fdisk, post the output.
Ok, so I've searched around and haven't really found an answer to my question, sorry if it's been answered before.
I'd like to format my ENTIRE SD card as an EXT3/4 filesystem, and was wondering if it would register as a normal SD card under Android, or will it be used a "system partition"? Would i be able to transfer files freely using a file explorer and would apps using the SD card (not apps on the SD card) for data run properly. I'd like to have a different file system used as FAT32 is a little ancient, and EXT is much better. I'm running Ubuntu as one of my OS, so mounting it on my PC wouldn't be a problem.
Thanks.

It would still be seen as an external SD card whatever file system you format it as.
Thanks. Although, i was reading through that thread and it says that the SD card will be reformated to VFAT on reboot. Is this true for the DHD too?
Possibly. I wouldnt know to be honest. Might aswell wait until somebody who knows about this can answer.
I am not sure if this is a common problem but ever since I've rooted my phone (and changed to a new 4gb sandisk card), my SD card became corrupted twice! Once was with Supernova rom and another was with Runnymede rom.
Does anyone have a similar problem? Could it be a SD card problem or is it an inherent fault with the phone/rom?
Never heard / read of that before. Is the SD card completely unreadable (so even Linux cannot read it), or just unmountable by ROM / recovery?
Had the same problem with earlier Seb's Runnymede version. The sdcard was totally wiped, nothing left.. mounted in Windows, it said the card was not formatted. But it was not ROM related, it was the recovery I guess. Change to CWM 2.5.0.7 and redo everything, never face the same problem anymore. Anyway no more on Seb's Runnymede but on my own modded ROM with RMD Recovery.. running good till now.
I had the same problem back in the day when I had my G1. My old 8GB Sandisk had been partitioned for the use with A2SD and for some reason I can't access the ext partition from phone/unix but I can access the fat partition. I can't even format the card as a whole.
I think the SD cards headers might have become currupted or something.
Had the same problem twice with a 2 GB class 2 Sandisk card. Both times the card was totally unreadable and Windows asked to format it before it could be read. Both times it happened all of a sudden. The 2'nd time i used "chkdsk -r" to scan the card for bad sectors and i've found some 8 kB of them. I have since replaced the card and all is good now.
Yeah, I think my 8gb broke due to bad sectors. If you are using A2SD, you are constantly causing many read/write cycles and the SD card might have not been able to handle such I/O.
Some SD cards come with a massive warantee (maybe even a lifetime). If you can find a receipt/packaging then send the manufacturer a repair request. They'll likely replace it. Do try everything you can to get it working. If you can't get it working using gParted then it is likely to be broken.
A2SD is constantly reading and writing to sd.
Also the type of file format used for A2SD matters.
The least relyable but the fastes and the most coserning the lifetime of sd is ext2, this isnt common due to stability issues.
ext3 is mostly the most common but it doesnt really do too much good in terms of lifetime of the SD card.
so there is ext4 which has all of these in mind and is as fast as ext2.
Also the scize of the A2SD format matters alot. The bigger the better one may think but that is wrong.
More apps have more reads and writes. And there is a limit that Roms can handle. This is usually 2GB, however not all Roms.
Cheers.
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.
