Hi all,
bought a samsung micro sdxc card from amazon... its the 64gb class 10 version here http://www.amazon.co.uk/gp/product/B009HPFUGI/ref=oh_details_o04_s00_i00?ie=UTF8&psc=1 received it and put loaded all the files from my 32gb card onto it and put it in my phone... all of a sudden the folders are all reading as empty and my card has 55gb on it (there was one file not in a folder that was read for some reason)... so put it in my laptop to see why they are empty or if they are and it turns out that a bunch of folders and files now had the u in place of the first letter of the folder/file name eg uovies, uooks, uusic etc... so I formatted the card using the phone and tried again... same thing... sigh... so formatted the card on laptop and tried again and this time only about half the folders appeared empty... soooo replaced the folders that were not being read and tried again this time more folders reading as empty... so I the replaced every folder individually and that took a while, checking every single time that the all the files had transferred into the new sdxc card... success... all files were there and so I put the card into my damn phone and ffs only the single file not in a folder was being read again... sigh...
to compound it sometimes the phone would say the card was damaged but I would mount it and it would read it was there fine... just nothing in the folders... I have read there are problems with these things and just wondering if anyone has found a fix yet... looking at returning it to amazon if I can not figure it out...
You could try changing the file system type, so for example if you're using fat32 you could try to format it in exFAT.
Sounds like a bad card or bad phone
For what it's worth, I've found out that the Samsung galaxy S4 will format your card to fat32. fat32 will only support files less than 4gig. The phone it's self will only support files in that range as well. Found that out after trying to share a few MKV type movies over 4 gig with some fellow S4 owners. Also the 64gig cards are defaulted to exfat, so no need to format. When I transferred my files from my exfat 32 gig card to my 64 gig card, all I did was copy all the folders to my computer and dragged them over to my new 64gig card and was easy as pie.

formatted it via phone and laptop... in the end I put folder by folder on the card and tried to see if it still worked... was going well till I got to a certain number of folders then the phone kept telling me that the card was damaged... getting a replacement from amazon now and will see how that goes... btw I dont have any files near 4gb... just loads of smaller files...
from my experience with 32 GB and 64 GB, both are corrupted regardless of they genuine or not.
i suggest you to go to 16 GB

hello,
i copied in the morning some folders into sdcard via.. card reader...
then i went off with the card..
on the way.. i found out.. my sd card was empty somehow..
i softresetted, nothing fixed it..
when i refresh and view all files.. i see only strange characters and strange folder names..
and the sizes all together looks like 50 GB.
but in fact the pda tells me.. there is only 1,7 GB free instead 1,9 GB..
my sd card is 150x Adata 2 GB..
how can i fix this .. please help me out.. i dun wanna reformat this card, as i have important files on it.
yup you are the proud owner of a broken partition (very common with Fat16 and mobile devices)
from expereince ive found it happens alot with Fat16 and lots and lots of files (like those found in many of the better games or if you have alot loaded onto the card)
my recomendation is to get to a card reader and get some partition management software ( i like the trial version of Partition manager) and rebuild the partition on the card.
let me know how you go,
You can try downloading PC Inspector File Recovery, and running it on the card. It's freeware, and should work well given your card is formatted with an older filesystem.

You'll likely have to reformat your card, but at least you'll get your files back. If you do have to reformat, and your device supports FAT32, please format your card in FAT32 instead. It has a higher "tolerance" against this sort of failure.

mmmk with a broken partition you wont have alot of luck recovering file clusters, at the very least you will recover things that look like file.001, file.002, etc as most recovery programs will recover pure clusters regardless on data.
and yes Fat 32 is good but you will still get partition faults if you load too many files onto the card.
People have been replacing their microSD cards not knowing that the problem is actually in the files and folders..
Ok here it is!
When i scroll through the hTC Sense tabs to music or photos, the applications try to load the thumbs from the Phone/microSD, that's when it suddenly freezes then the microSD vanishes..
I inserted the microSD into my PC and browsed the drive in "Thumbnail view" and guess what happened, it froze.. I figured since the idea was the same in hTC Sense when it tries to load any thumbs..
So i went to the microSD drive again and chose "detailed view" then went into each folder and changed to "thumbnail view" until i found two folders that kept freezing; "Program Files" and "My Music"..
In Program files the only folder that couldn't be deleted definitely had files that were behind the issue.. There was a music album too that froze, i deleted that too...
I backed up my files and formatted the microSD, i had to, because the folders behind the microSD disappearance cannot be deleted even with an "Unlocker"..
So far i'm playing around with my Leo and nothing is happening..
So by viewing the folders on the PC using Thumbnail view, you'll be able to identify the file or folder behind this annoying issue..
I had the same issue
I have (had) Sandisk microSD 16GB card. It was last week that it happened to me. Only backup of good files and re-formatting the card helped.
Today, I was copying 700MB file and suddenly it told me - cant write on a disk. I disconnected cable from the PC, rebooted Leo and SD card was no more present.
I put it into a card reader, tried to format it, but nothing is working. SD card is probably faulty.
So be aware, that that problem might be a first sign before your SD will break.
I think the fault is from some files somewhere in the microSD.. After going through the method i mentioned earlier, up until now my card is fine..

yup right, but be aware. I dont think that normal SD card should perform like that. I am using stock 2GB SD now, and it is ok!

My 16GB microSD is Sandisk and its 100% compatible with this device.. The Leo is doing something when loading the files creating some system files i suppose..

guess what? windows could not load sandisk microSD 16GB and I was already preparing to return it to e-shop, but I tried live cd of ubuntu 9.10.
It can read the card, it formatted it and it is working again! :-D

That's great, so you didn't have to replace it?
But strange, i've always been using the 16GB with my HD and now HD2.. The issue just occurred a week ago..
A day has passed and everything seems fine..
I hope it stays that way..
ok
I got exactly the same problem with my 16G Sandiskin and HD
and found that the problem was a damaged file in my SD
connect your SD to your computer throw card reader, using total commander or whatever, begin coping all SD files and directory to your hard disk, until get a message can't copy "file name", this will be the damage file, unmount the SD and mount it again and delete this file and your SD will be ok
ps: may be you have more than one damage file, try the this method until you can copy all SD files to your hard drive
When you have a write or read problem with a particular file, it usually points to more than just a corrupt file. In my experience with 4 16GB Sandisk microSD, it is the beginning of a failing card. The safest bet is to copy out the good files, reformat in your HD2 and copy the files back. But if it happens too often, it may be time to invest in a new card as your data is of primary concern.
The strange thing is that this usually occurs with the bigger cards, 8GB and 16GB. I never had this issue in the past with smaller cards.
I back up my card weekly or when I have updated large number of files just to be sure I have a valid set in my PC in case the card fails.

I know what you are talking about. Low format may help. I had the same issue with 2GB SD card 3 years ago (had to recover SD card to save few photos) and also on my DLSR with 4GB CF Card (linux helped to read the card). I don´t think it can be damaged so quickly as normal PC HDD, but when it happens often (damaged files on card), it may be a sign of something wrong with the card.
Unfortunately it happened again.. After a month of having everything under control i got the same problem.. The great news is I'm using windows 7 on my PC and when i plug my microSD card via usb reader, i get a choice of scanning and fixing the removable disk...
Now i'm happy without those annoying corrupted files..
Would it be possible for me to copy the entire contents of my 8gb and paste on folder on pc, then put in new 16bb card and paste the lot back onto the new one, would everything work ok? as i have most if not all my apps instlled on my storage card, has anyone done this b4 and is it possible?
Thanks
I've wondered that myself, as long as the new card is properly formated then in theory it should be fine..... never actually done it though so don't take my word for it.
Maybe someone can clear this up, by format properly what do you mean by this?
I have done that twice without any problems. Just rember to show all files in the explorere on the PC.
I have previously done it twice with no problems but i just swapped my 16gb to a 32gb and it wouldnt have none of it????? I have had to return the card thinking its faulty? But i will do the exact thing once i receive my replacement

I got a Sandisk 16Gb card and though it was faulty as HD2 wouldn't read it. Examining it on PC showed it was formated as 'exFAT'. Reformatted to 'FAT' and copied data across and now all OK.
i've done this on every winmo phone i have had where a sd card upgrade was required. Just make sure you have the phone off while to do it and use a card reader just to be safe
dont have a card reader, know how to format to fat on pc via disc drive mode, will just copying all to pc, and ensuring all files are showing and not hidden then would this be ok?
the 32gb came formatted in fat32? I have been told that my replacement will be here tomorrow
yeah if you format the card to fat your gonna damage the card. stick to fat32 and use a 32KB allocation unit size. you do it be finding the drive in my computer, right clicking and hitting format. Setup your options and go.
Card readers are best for this type of work and you can pick one up less than £10 from amazon.co.uk. Just make sure it says it supports SDHC cards.
CHEAP MicroSD reader....

Ok, so I'm going crazy now, but I just can't figure out what's wrong with my card.
I bought a new 32 gb card. I know, I know, you're gonna say it's a fake card, but it's not. I tested it with H2testw and it fill up the card with 32GB of random data.
So, here's what's happening.
1. The card came formatted, I just swapped it with the old card and the Tab recognized it without problems.
2. I took it out and copied backed up files from the old card onto it.
3. When I put back the card into the tab, only a few folders were visible and other data that was copied and visible via the card reader was no where to be seen on the tab.
4. Then I took it out and tried repeating the process - same thing.
5. I tried quick formatting the card through the PC, and tried everything once again. Now the results were different, but again not all folders were copied.
6. I tried formatting through the Tab. The format went fine. Then I tried copying files through the USB cable (mass storage option). That also went ok, but a few of the files could not be opened. Scanned it with disk check and automatic fix error option.
7. Back to PC, did a full format with a Panasonic sd card formatter. Ran H2testw. No problems. Put the card back, re-rooted the tab (since I started suspecting it could be somehow related to this).
8. The card is back in the Tab, but it's still showing some strange behavior, such as folders dissapearing or files not being readable.
Anyone have any idea what to do? I would also like to note that the card works fine when in my reader, I can copy files to it, open them directly from the card etc. No problems at all. But as soon as I put it in the tab it goes crazy.
P.s. The tab is rooted, firmware is out-of-the-box. I have app2sd, but I didn't put any of the apps on the old card, and all apps work normally with or without the sdcard.
I dunno. Bad card? Or maybe just incompatible with the Tab?
just wait android 2.3 to fix this program
Sent from my GT-P1000 using XDA App
the card is fake,
i had this a while ago, i could copy files over fine and the files showed in the file structure in windows explorer. BUT if i restarted the computer loads of the files went missing, i then found out the 32gb card was in actual fact an 8gb card but some trickery makes it look as if you have copied 32gb over. the best way to test it is to copy over say 25 films at 1gb each, see it copy over, restart your computer and then see how many are left after the restart, you will then see how big your card actually is!! Sorry to be the bearer of bad news but i hope you can send your card back and get a full refund.
I have tried a genuine 32gb card from expansys which works correctly in my galaxy tab (JM6 firmware) and my x10i.
AFAIK only Sandisk and Kingston make 32GB microSD cards now.
I got my Kingston 32GB card from Newegg and it works great in my Tab.
Where did you buy your card?
I would not dare to buy SD card from eBay or from a store that has no good return policy.
[Q] Move apps & files from full 64 GB microSD card to 128 GB card without corruption?
I filled up my 64 GB card with apps and files and so want to move to a 128 GB card. However, I've seen many cases of files being corrupt or cards being unreadable/unmountable after using a (Windows) PC for the transfer. What's the proper route to do it for the S5 without those problems?

you need to back up everything on your 64gb sd to your pc then before you put the 128gb card in your pc put it in your phone and format the card so you know its working on your device then after that put your 128gb micro sd into your pc and copy all the files over that you had backed up from your 64gb memory card, and know this works because ive done it.
