[Q] Strange problem with 32 gb card - Galaxy Tab General

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

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.

microSD disappearance.. SOLVED!

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..

Swaping sd cards over

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....

Need help with 64gb sd card

hello...here's my problem:
I just purchased a 64gb sandisk sd card and it doesn't not work...
more specifically:
1) whenever i re-insert the sd card, it shows "blank sd card, need format" (ONLY if i formatted the sd using my pc before i insert it back)
2) i tried to format to exFat and FAT32 through my pc, it works..but when i insert it back, it's gonna show either "blank" or not able to read any files that i copied to it.
3) when i connect it (inserted to the phone), i cant move a large number of files, it's either gonna disconnect or some errors.
4) i notice whenever i managed to copy all my files to sd, after reboot, it's gonna show "blank sd" again.
5) i also try copying the files to the phone first and then move them later using phone's application, but when i wanna use those files, it's not usable.
6) i think sometimes it deletes all the files that i moved from phone to sd card.
Please help! any suggestion will do...ihv been looking for answers in this forum for like 3 hours.
(English is not my first language so bear with me)
do not use sandisk 64g, mine got file not found at random, using 32g is fine
As mentioned sandisk has gone downhill...Ive had issues with them also. That said it sounds like your card is no good. Return It if you can
Sent from my SM-N900W8 using xda premium
If you can return it--recommend the Samsung 64gb Class 10 on Amazon
ZERO issues and pretty fast
Did you try to format it with your phone ? not PC.
Because i also have Sandisk 64GB micro sdcard i had it since Galaxy S3 and now use it with Galaxy S4 , and have zero problem with it , it works just fine. I keep it almoust always full and even encrypted it.

Disappearing files in MicroSD Card.

Greetings,
I transferred my Pictures and music from my old SanDisk ultra 64GB micro SD card to my new Samsung Ultra + 128GB card. My first attempt at loading the data was through the restore function on the LG Bridge app from my PC. 3 day later when the restore was finished the phone indicated that the data was corrupted and had to be formatted. The second time I got a "file Corruption" message on my SD card when I was transferring files while both cards were in card readers. The next attempt was with the old card in the card reader, and the new card in the device, with the device connected to my laptop directly by USB, the end result being the Corrupted file message (again). My most recent attempt is by downloading files from my PC to my device card. Now the files are gone when I restart the device. The Music file in my folders are gone but the music outside of the folders are still present. All my pictures on my card are gone as well. ANY help is desperately needed and appreciated!!!
Did anyone have an answer to this? I'm having the same issue with my V30 - the files I copy to the external SD card by any means (AFT, SyncMate, FTP, SyncTunesMac) disappear...
I don't have good news for either of you that sounds like the sd card or the card port are going bad. Is it possible your ad cards are counterfeit as in does this behavior happen with another known good card...
I would try the following
First backup anything you can
Try a known good card that works in other devices and see if the behavior persists if yes
It is an issue with the phone not the card if the behavior stops you both got bum cards be more careful where you buy amazon is not even safe.
If the behavior persists try resetting the phone full factory. If custom Rom reload the rom. If the issue persists past that you most likely have a hardware issue that requires mainboard replacement.
Also try uploading files to the cards using the computer(with the micro sd to sd adapter) and check if the files stay(using the phone)
I had a similar issue with Moto G Turbo with Lollipop. It permanently damaged 2 MicroSD.
I ended doing a factory reset and MicroSD worked correctly again.
Counterfeit

By the above description, this is almost certainly a counterfeit sd card.
Google "H2TestW_1.4.zip" to test ANY card you buy before you ever use it.
It's a solid, lightweight program that does its job well.
Anything that says it will do the job better / faster is blowing smoke up your skirt.

Tablet no longer recognizes SD card after October 2022 software update

My tablet kept bugging me to install the latest update, so I let it do so. After restarting, it no longer recognizes my 200 gb SD card. My computer has no trouble reading the card (it's backing everything up from it now). The card had been functioning just fine until the update. I put in a 128 gb (previously used) sd card I had around, and it didn't read it either. I then fed it a brand new (64gb) card, and it apparently formatted it and recognized it. Has Samsung changed the required file format for SD cards? It seems to want me to reformat my card (hence my backing it up first). Any other options? Of course, the info presented before the update said nothing about causing SD card issues
I dont know man.
I backed up the card, allowed the tablet to reformat it, and recopied everything by inserting the card into the pc. After the recopying it didn't recognize it again. AARGH! So I let it reformat it again, and am now copying just the essential stuff with the card in the tablet and the tablet connected via usb. Windows is telling me this will take 9 hours just to copy one folder with 6gb and 7k (smallish) files. I hope Windows is lying about the 9 hours! There was originally a folder .android _secure. I wondering if copying that over the first time is what prevented the tablet from recognizing the card. So that's not being copied over this time. There's another ginormous folder with about 100gb of largish files. But given the app they go with will probably insist on redownloading them anyway, I may leave them off.
I found there is a statement about the Micro Sd Card in the latest user-book (for Android 13). It says, the system support the format of exFat and Fat, but when you slot the sd card of different format to your device, the system will require a reformat to use it, or your device will not identify the sd card. You can check it on the Samsung website, for the edition I read is Chinese.
