I had a Wintec 16 GB Class 10 MicroSD in my USB slot, using an Elago Mobile Nano II USB 2.0 microSDHC Flash Memory Card Reader.
Worked fine for a couple of weeks.
Then, I tried to transfer a 500 MB video file from my dropload folder to it, and the transfer kept crashing. The file showe up only when I read the card in Windows, as 190 MB. And, it would not delete. So, I formatted the card, and bang, zoom, dead card. Won't format, won't read.
Happily, I am within Newegg's exchange period, so it is being returned.
But, has anyone else been able to transfer files that big? In the future, should I rely on Windows to put large files onto a MicroSD?
Wintec cards are pretty much crap... I bought 2 16gb class 10's at Frys and one of them worked for about a day. Now I can't even format the thing... I'd return it but I bought them in Vegas and took them home to Vancouver. I was a bit weary about them due to the price but bought them anyways... I have a feeling the second one will fail at any point too..
I moved 15GB to my Sandisk at once and got no error. Guess I'll stick to the brands that work.

Hey all
I just bought an SD card from eBay and I'm suspicious that it's an original Sandisk card... My first concern was about the box being decidedly homemade looking (and the card itself wasn't in any vacuum sealed container either) - but now I find I'm having trouble with it as well.
I couldn't find out what size SD cards are supported by my XDA2i so I just went ahead and bought a 1GB one. However, if I transfer around 512MB onto it - it then informs me that the card is 'full'? But when it's formatted and clean, it shows free space as 998MB... What is going on???
Any help is very much appreciated thank you.
Paul
1024mb unformatted, around 998mb formatted is about right.
I have a branded SanDisk 1gb card, and it's fine, there's no difference in file transfer speeds or use than with my high speed PNY 1gb card.
Although thinking about this more, I have read a few reports of counterfeit flash ram chips that report one size, when they are in fact much smaller.
It's apparently been reported on ebay many times where people have bought 2gb usb flash drives, and they are in fact 128mb, even though Windows reports 2gb.
Maybe you should see if you can get a refund?
Is there any way to check to see if the card has been tampered with in any way? It doesn't matter what I do with it, it continually reports being a 1GB card until I put up to 512MB on it and then it claims free space only up to 512MB?
Paul
Incorretct SD sizes??
What file system have you formetted the SD card as?
What size files are you putting on there?
Remember that there is always a lot of wasted space when using small files...
i've tried two 1 Gig SD cards in my XDA 2i now and both of them have the same thing go wrong with them
Seems the 2i doesnt support 1 gig cards properly and sometimes (especially when transfering large files) stop functioning and/or slow down to crawlspeeds.
Alot of the time mine has reported being full even though it isnt. Eject it then insert it again to fix it but the transfer will be rejected.
The only reliable way round it is to transfer smaller files, try Zip'ing the files into smaller chunks ?
I have a pcmcia 1 gig card, its an ata flash type, it used to give me the gig storage until i formatted it on an ipaq, now i can only get 512meg, nothing i do can fix it.
I've formatted it as FAT and I've transfered 56Meg of ScummVM stuff onto it, the rest are large 3ivx files (which are between 50 and 150Meg each). Thing is that I also have a Dazzle card reader which gives the same results? Mind you that's quite old now I guess...

I originally had an 8gb class 4 card and when transferring files between my Nexus and PC I noted speeds of up to around 3mb per second.
I recently invested in a 16gb class 6, but now when I transfer files I am very lucky to even reach 1mb per second. This card is incredibly slow, is this right? I thought class 6 were supposed to be at around 6mb's per second?
strange that the speed is less that the class 4 sd, but u cud confirm the card transfer speed using a card reader
but in any case, you shud note that the phone limits the transfer speeds so u mite never get the full transfer speed of a class 6 card...
Oh, I did not know that the phone would limit the speeds, still, it does seem strange that the speed is less than my class 4.
I shall do what you suggested and try and get hold of an adapter to use my card reader

Where did you buy this card from. If it was off ebay, then it could be a fake & that would explain the 1mb transfer speed.
I recently bought a Kingmax 16GB Class6 microSD card. While I was initially transferring my files from my Sandisk 8GB Class2 microSD card, I noticed that the transfer rate was kind of slow, so I decided to do some benchmarking.
Software: CrystalDiskMark 3.0
3 different microSD cards using same USB card reader
Card #1 - Sandisk 8GB C2
Card #2 - Kingston 8GB C4
Card #3 - Kingmax 16GB C6 (new one that I just bought)
Here are the results (Seq Read; Seq Write; Random Read; Random Write):
Card #1: 17.08MB/s; 5.13MB/s; 17.09MB/s; 1.05MB/s
Card #2: 17.23MB/s; 9.53MB/s; 17.23MB/s; 1.92MB/s
Card #3: 16.05MB/s; 5.22MB/s; 16.73MB/s; 1.02MB/s
Summary: My new Class6 card was about the same speed as my Class2 card.
I approached the vendor and they tested a few other Kingmax card that they had in stock... all cards were reportedly about the same speed as the one they sent me. They swear that it's not fake. Maybe its a bad batch of cards but somthing is weird/wrong. Anyways... I'm sending my card back for a refund. I am going to stick to my Kingston Class4 card now.
1MB/sec can be indicative of USB 1 speeds, is OP sure that its connecting @ USB 2?
The class is supposed to be the minimum write speed, and I assume that to be sequential.
>Kingston
isn't that ring the bell? I mean they are pretty expensive....
I think if you go beyond certain level of quility, the pay off of such c/p ratio will get narrowed and you can't tell difference......
either go dirt cheap or go super HD expensive, middle is kind of "uh they are more expensive than dirt cheap but not even close to those expensive things....."
like my AMD vs INTEL war, cheapest AMD almost always beat middle/low Intel by cost + performance, or just go get best INTEL and enjoy the hell out of it.
happy new year
I bought a micro sd of kingston class 4 16GB in the store, not happy with it at all.
In the beginning it had issues because i couldn't put any files on it. Eventually fixed that. A week ago i couldn't put any movies on it, let say files bigger than 100mb. Now i can't put any songs on it:S
Already did chkdsk, and formatted it like 20 times, still same problem

Go back to the store and maybe ask for a new one??they have lifetime warranty
is the card format are fat32?
Yes 1GB ext4 and remaining is FAT32
Then have u try to copy the file using the card reader?
Give the card back and buy another make. I bought one of these a few months back and it was causing me a lot of hassle. I had it replaced with another one and same problems again. In the end I just gave it back and went for a Samsung 8GB class 6- has been working fine so far.
Hello,
Just to let you know, I had a Sandisk 16Gb class 2 and I replaced it with a Lexar 16GB Mobile MicroSDHC Card Class 6 High-Speed and it's working not to bad, I'm really happy with it, much faster then the Sandisk.

Yeah, I was pretty certain it would work. It has worked on every Samsung Galaxy ever made so far. I think BestBuy had it for $70 one time. Still waiting for that deal to come around again. It might take a while...
But then again, 128GB might be better. It would be nice to carry every episode of all my favorite rewatchable TV Shows and all the TV Shows and Movies I plan on watching some day. Might take 2TB. Someday...
Wow crazy space. Let's hope they make batteries in the future to allow us to make use of all this video space
I put the same one in mine, when I saw that deal. Works fine. However as a word of advice from wasting time..........
Many state to use the sdcard.org's formatter which then formats it correctly and then put your data on it and then put it on your phone. However that doesnt work. sdcard.org formats the card as exFat and the phone cant recognize that. Let the phone format it which it will do as Fat32. Then it works fine.
Many threads state to use the sdcard.org formatter to achieve the best speed, thats the reason why I did it. So despite their recommendations, dont bother, it wont work.
On a side note of reivewing it. This 64gb card replaced my Samsung 32gb Class10 card. I have to say to say this 64gb card is REALLY slow when transferring data. It took a good 1hr to transfer 32gb of data on this card. The fatest I got was around 4-6MB/sec. The Samsung 32GB card (being it was class10) was at least twice as fast. But I cant complain too much, I mean its twice the space. Im sure a Class10 version of this 64gb card will cost over $200.
Dixit
Awesome good to hear, didn't think I would hit 32GB but I'm fast approaching, time to upgrade I think.
Like dixit said.... It's always best to format in the device you're going to use it in!

I'm affraid I will have to disagree with you on this. I purchased the card .. it was already formatted with exFAT. When inserted into phone, does not recognize it installed at all .. will not format, will not mount .. nothing.
I'm running Windows 7 Ultimate 64 .. does not format FAT32 unless you're doing it be command line .. however, here is the issue with that .. standard command: format ?: /FS=FAT32 for the 64GB card took 2 hours to format, only to find that it errors out right at the end stating it is not compatible and over 32GB .. waste of time.
Hense .. this is why I attached a link to a command line program called FAT32format .. I executed this program from command prompt .. and poof, 64GB formatted FAT32 .. plugged into phone .. phone recognized the card, no problems at all .. I did however reformat the card via the phone afterwards.
So, for the initial installation (out of box) our phone WILL NOT see it until it has been formatted FAT32
Well mine had no problems reformatting on the phone itself. When I first put it in after the sdcard.org format it was exFat. Phone as you stated didn't recognize it. Then I just on the phone told it to reformat it. It did it just fine as Fat32. But either way like you said as Fat32 it has no problems.
Dixit
The only issue here is that you can't transfer files larger than 4Gb to the card when its FAT32. Something to keep in mind if you have large files.
I bought mine about 6 months ago and haven't hd a problem with it in any android phone and I formatted it in the phone. Now I'm just waiting on this skyrocket hd to come out and I'm selling this phone and buying that one. Has any boy heard any thing about a size bigger than 64gb
Sent from my SAMSUNG-SGH-I727 using xda premium
thanks for the note, it's a great price, but media-scan kills me
I love the space, I don't care about slow speeds because I usually dump data on the card (huge mp3 collection) and keep apps on the internal /sdcard (16GB)
The problem I see with this is that my current 32GB class10 card is being scanned by the phone periodically. This scan takes a LOT of time and 64GB would be even worse
If I find a phone that is equal to or better than Skyrocket + support exFAT I would go for the 64GB card in a heartbeat
Do you know such phone as of today ?

thanks for the tip on FAT32format. my 64GB card showed up yesterday and i was fearing i had wasted money since i couldn't get it formatted to FAT32. i bought it after seeing that YouTube video (we've all probably seen it) to put in my Galaxy S i'm turning into a dedicated PMP. the phone wouldn't format it (would try but it would always say damaged) but this worked like a charm. i'm transferring my music collection as i speak. thanks again for the help!
Browsing this thread and checked out the Best Buy link. Price is $79.99 as I write this.
$71 on Amazon now.
Adorama Camera $59.95 and free shipping if anyone is interested.
^^^^ thanks for the link, i have a few friends looking for this

Just a thought, cuz I haven't noticed anyone say this but from what I've read class 6 and 10 cards are not ideal for mobile phones because they are optimized for faster sequential read/write (ideal and fast for cameras). Class 4 is faster at random read/write than 6 and 10(ideal for phones).
I just purchases a sandisk 32gb class 4 and I've never had it randomly scan and I use it for music, photos, some app data, backups etc.

this is unfortunately somewhat true. Class 6 in the OP should be okay though. I'm currently in an RMA process with Sandisk and in talking to their Technical support they said :
"We need to take the few information from you in order to process the RMA request. There is an ongoing issue is with Sansa Ultra 64 GB SDXC class 10 Cards the one which you have and on Android phones we need to use the Sansa Ultra 64 GB SDXC class 6 in order to make it functional. It depends on your requirement so please let me know so we can proceed with the request."

THANK YOU! So much, you helped me out of a jam. Found a SanDisk Class 10 online for $64 and was freaking out when my phone wouldn't recognize it but using the FAT32format program through the Command Prompt worked like a charm so my deepest THANKS! :good:
I have tried both a 64gb and a 32gb micro sd card and if I try to save or backup my documents on it sooner or later a few weeks down the road my Note Pro 12.2 reports that I have a corrupt card. I never take it out so that is not the cause. I do not have any apps installed on the card. I am not rooted.
All I am trying to do is keep my music, videos, pictures, and a copy of word and excel files on a micro sd card but I have no trust that my micro sd card is going to work.
I have formatted these cards using my Note Pro. I have formatted these cards using my Windows PC. But several weeks down the road I get the corrupt disk error... please reformat!
Is rooting the answer?
Any help is appreciated.
Sounds like a bad card to me. What brand is it?
Sent from my SM-P900 using Tapatalk
This usually happens with low-class or cheap-brand cards.
In general you're best off only using class 10 or above cards by Sandisk or Samsung. Anything else is highly unstable.
I have a San Disk Class 10 64gb but my other card is a PNY Class 6 32gb. I guess I'll look at getting a Samsung? I believe I had read somewhere about this device not liking 64gb cards? Or maybe I read something about it not allowing files to be saved to external storage. Something Samsung was doing.
Anyway thanks for the input. I would like to use a 32gb card as I really don't need 64gb so if my PNY isn't going to work I need to get something that will.
How does this card look?

If that samsung is as fast as it's rated that looks like a good card.
I'm using the Sandisk Extreme Plus 64gb but have only had it for a month and a half. So far no issues but I wonder if it too will be a time bomb.

There's no issue with 64GB cards. There's no issue with 128GB either. Some of the older devices had issues with SDXC UHS-I cards, but that was over a year ago.
There is, however, an issue with Android KitKat no longer allowing non-stock apps to write to the SD card. That's Google's doing. It has nothing to do with corrupt cards.
Samsung and Sandisk cards are both excellent. Just make sure they're class 10 or higher.

What is the best method to copy delete movies to/from my micro SD card? Should I unmount it and remove it or should I power off my tablet and remove it. Or will it be better just to copy them from a USB stick to the card while the card is still in the tablet? I'm hoping to keep 10-15 movies on my card and swap them off to put more on probably every 6 weeks and I want to know which way is the best way not to harm my card.

Unmount the SD card through Settings --> General --> Storage --> Unmount SD Card.
Or connect the tablet via USBcable to the PC and copy it onto the SDcard that way. (It loads as a network device in explorer)
I've got 11 films, two shows and a handful of concerts on my MicroSD and swap regularly, I usually use one of these two methods.
For me, I use a MacBook Pro which for some reason does not allow me USB 3.0 connectivity to the tablet (driver issue I'm sure but try as I might I have never gotten it to work). I therefore use a USB 2.0 cable and Kies to copy files to the tablet that way. I'm able to pick the external card as a destination and transfer at USB 2.0 speed.
