[Q] Slow MicroSD performance (Fat32, 64gb) - Galaxy S III Q&A, Help & Troubleshooting

I followed some instructions to organise FAT32 mode on a 64gb class 10 genuine sandisk card (I've checked / benchmarked) so that CWM would work on it.
Problem is, Winamp for example is taking FOREVER to load the thumbnails for my music located on the SD card :/ It's like there's a slow disk access problem.
Is this a known isue? Have I done something wrong?
Any thoughts on this?
Thanks all

Good morning.

No one, please? Should I reformat this to another format or not?

From Sony's support site:
"The tablet can recognize SD and SDHC memory cards (Class 4 or higher) up to 32GB in size. External USB Hard Disk up to 2TB (Terabytes) have been tested and will be recognized, as long as the drive is formatted in the FAT32 file system. Similarly, flash drives of any size will be recognized as long as they are formatted in the FAT32 file system."

ive read here some one has tried 64GB SDXC card on it
is that right can some one confirm before i buy it
thanks
there is this... http://forum.xda-developers.com/showpost.php?p=20273764&postcount=4
I use 64 sdxc. bought the cheapest and format it to fat32 with third party tool. works excellent.
I use a 128GB SDXC card with mine. works like a charm.
http://www.bhphotovideo.com/c/product/756124-REG/Lexar_LSD128CRBNA133_128GB_Professional_SDXC_Card.html
here is the link to the card I'm using.
I know this is an older thread and well not trying to be a noob. I see it does work with ICS update as well but my question is do you have direct access to it or do you have to transfer to the internal storage to use it?
I use MixZing for music MX player for movies and Astro for everything else. All these work with the specially formatted SDXC?
does the gallery app with the upgrade work as well to get access to photos on the card. I have heard that some programs will not find the card at all.
I don't have ICS installed, so many of these things will have changed.
In Honeycomb, the Sony stock apps required copying data to internal storage, but third-party apps could access it just fine. The only problem (which caused the occasional app to not find the SD Card), is that most devices mount their SD Cards as either /mnt/sdcard/external_sd or /mnt/external_sd but Sony instead (at least in Honeycomb) mounted it at /mnt/sdcard2 so some apps might not see it, but most still should find it.

Micro SDHC 32GB Class 10 Card Problem

Hi, I just recently bought a Sandisk 32GB card and have it reformated before transferring it with music and videos. All is well, I can play all of my music but randomly, the music player will stop playing and I can't access the contents of the SD card anymore unless I reboot the phone. Tested it with H2testw and its genuine. Is there any way to fix this?. TIA.
Sooo, I am NOT the only one who has this problem.
Yes, this happens for me, too, with a class 10 Samsung 16 GB SD Card.
Just yesterday the card also lost files when this happened. Checking the SDCard revealed no problems whatsoever.
So now I wonder: Is the card reader not okay, is it a compatibility issue between certain cards and the S III or is it a firmware bug.
Format the card via windows as FAT32 may fix problems .

screw...think im having one such problem now....anyone knows how to solve it?
Backup your files and format it again
Its recommend to use samsung sd card
Its very fast calss10 and designed for samy android devices.
Sent from my GT-I9300
Same problem for me... thougt it was CM10 problem but no, have same problem with Omega rom.
Formatet it multiple times with diferent systems. Having problems with pictures too, I only see 1 folder out of 5 :/

[Q] MicroSD card issue

Hello there,
I just bought a 32GB Class 10 Samsung MicroSD card.
After inserting it, I made sure the phone sees it, and the computer sees it.
So I started transfering files to it...
Every time I try to transfer files to it, the cards sort of unmount, the computer stops seeing the External/Internal storage drivers info (0/0 KB and no files).
I realized I might be needing to format it, so I went to recovery and formatted the external card. Still no good...
If I don't try to transfer files, the internal sd card still works fine.
Am I formatting it wrong? or some other issue? Did I buy a faulty card?
Thanks!
P.S. Some info incase needed:
Using Galaxy S2 obviously, Resurrection Remix ICS 4.04
My PC is running XP SP3
[edit]
Added some pictures to demonstrate what I mean.

Pic 2: The error I get, doesn't mean much except that the pc doesn't recognize the storage device, but just for the heck of it.

If unsure about the quality of your SD card google for h2testw. It is a Windows test software you can use to test your SD card.
Tried formatting it... still no good.
And h2test tries to copy a file repeatedly and after some time it also gets stuck like I do manually...
I was running into the exact same issue as you with an SD card awhile back. Tried many, if not all of the suggestions listed here. Sometimes, the cards just die on you, especially at the most inopportune times...

Open CMD
Type format [letter_of_external_card]: /x
ex.
format E: /x
and wait.
Then format again (through Windows Explorer) with this settings:
FAT32
default allocation size
fast formatting checked
and share the results.

Failure of h2test is normally due to defective hardware.
For SD cards I do not really know but when it comes to USB sticks there are many around that are just cheap crap. You could for instance buy a 8GB stick that will happily accept 8GB of data but only store 4-6GB!. This is where h2test comes into play: it will not only write but also read and therefore check if the data written was really stored in the flash.

Class 10? That card might be just too fast for your hardware.
I'm using Sandisk 32GB Class 4 and never had any problems.
I have tried some Class 6 and Class 8 cards with very various results.
Only class 8 card I found correctly working in my device was Memorex, but it was only 4GB.
So I gave up on fast cards...
its fake or corrupt,did you buy the samsung off a retailer , you always test flash with h2testw before you use it, speed is not the issue,i got a class 10 32gb i had many 16,256,4gb fakes, only 3.7 gb usable droped down to 1kb write then windows couldnt read the storage so you reformat again.

[Q] Troubleshooting Micro Sd for Galaxy S3 - My findings & Questions

So I purchased this Micro SDHC card when I was overseas thinking its a decent deal.
It was a Verbatim 16gb Class 10 (Verbatim 44010)
Long Story Short:
I had to format the card to exfat in order for my phone to write to it.
Using fat32, the phone can read the card just fine but can't write to it.
If I tried to format the card with the phone, I get the same problem (I guess the phone formats it to fat32?)
The card reads/writes fine in both formats when plugged into the pc
What do you guys think? Something is wrong with the card?
A its a question .
Probable faulty card .

I9300 and 8GB SanDisk Class 10 SDHC
This is the version that is branded as ideal for Android that came with a Sandisk application for you to download.The card has been working fine for 1 month and then suddenly while my computer can read/write to it just fine....the S3 can only read the contents from it but can't write to it. It is originally formatted to FAT32, now my phone can't copy files to it (whatever file types) using the stock file app and the camera won't even save photos to it with an error that says "copy failed" or "can't save to storage".....Having seen this post being the closest to what I am experiencing, I am wondering if I should try exFAT too.....

[Q] μ files on my sd card. is GS3 frying sd card?

First of all, im using a 4.1.2 stock and my device is rooted
So i had an Sandisk 64 GB class 10 for some time which one day became a "read - only" card...
So afterwards i bought a Samsung 32 GB class 10 which I found out also had problems because i could put about 10GB of files and everything more that 10 GB turned into wierd folders that their name starts with "μ" and there where no actual content inside and i couldn't delete them.
So now i'm at my third try, again with a Samsung 32 GB class 10 which also has the same problem, only now i can write on it about 20 GB of data before files start to get curropted.
Just want to say i bought all 3 SD card from Ebay, and though i guess they might be fake (tons of bad luck), after searching the web I found out there are many GS3 users with the same problem...
So i just want to put an end for this question..
Is GS3 frying SD cards? is there something i can do to stop it from destroying SD cards? can i fix somehow the SD cards?
thanks alot!
Hi! when you are asking a question you should include details such as operating system(4.1.2 , 4.3, 4.4, stock, rooted and so on) and file system. I noticed while searching google that the majority of "s3 fried sd cards" so to speak are sandisk and in your case it seams that there is no such "limitation". Maybe if you give more details someone might be able to help.

Well, I edited my post.
you can see the first lines contains the detailes you described.
can't think of any other relevant details.
What type of file system do you have on sd card? is it fat32 or Ext4?

not sure. I formated it with my GS3 and the computer won't recognize it without reformating it.
Worst case scenario is your phone somehow corrupted the sd card and that is that. I had a similar problem with my usb flash drive which i used on-the-go and unmounted it before removing it but when it happened i didn't make a backup(as always) and got stuck with a nice keychain. If you have the possibility to format it under windows with a card reader and choose fat32 at least you have a working sd card, otherwise use your warranty for the sd card(if you have one) and always BACKUP.

but do you think that my device is malfunctuning in a way that will keep frying my SD cards..?
well since this is the second sd card i personally send it on warranty(as hard as it may be without the phone) because it seems that something is not right with the contacts of the card reader circuit board. I read somewhere that on some phones the card reader slot had some contacts partially detached and so the sd card kept getting corrupted. Search a bit on google about this issue and take into consideration using your phone's warranty. Best of luck!
That is a bit strange. Unless you're used to remove the sd card with the phone accesing to it (no safe removing) or removing the battery while the phone is running, that's absolutely not normal.
I have my 32GB sd since 2010 and I never had any problem. I formatted it this year because it had tons of useless data and I liked to have it clean.
Of course it's not from Ebay! That is bulls**t and use to fail suddenly.
