Hi there, not sure if this is the right place to answer this question.
Gutted to know that the amount of storage lost on a 400GB Sandisk Card was close to about 32GB. Of the 400GB capacity, 366GB formatted was available to store files. I found this out by multiple people and by putting in the adapter to my computer. I also realised the read/write speeds were slow but acceptable and comfortable for normal use. Later, I put the SD card into my phone (Xiaomi Redmi 5 Plus at the time) thinking it would work without an issue. Well, it did. In fact, it worked even better. Read speeds were close to the advertised amount at almost 100mbps and the write speed was just under 50mbps so I was happy. I also came to realise that the formatted capacity on my phone was showing as 394GB instead of the 366GB most people get on their computers.
I now move phone to the Razer Phone, as soon as I pop the SD card into the phone, it asks me that it needs formatting to a compatible format I believe as the 400GB capacity may have been too large or in the wrong file format. I haven't done so yet since there's about 25GB of files I want to keep (transferred from my previous 32GB card).
So I couldn't find the answers online for these two questions.
1) Why was the formatted size different on a computer, and on the Xiaomi?
2) If I were to format the SD card to a compatible format, I'd lose out on a lot of storage due to an unused partition. Correct?
Any responses are appreciated.
Thanks a lot

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.

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...

Hello everyone.
I have this strange things going on with my microSD card.
Recentely i bought 32 GB card for my nexus one (using cyanogen mod 7)
When i use that card on my pc i can write all the files at 5 MB/s speed. Then i put it inside my phone and it doesn't mount. After few tries like 4 or 5 it mounts but after that some files are gone from sd card. Allways leaving like 30 GB of empty space. So if i write more it will delete some so it would be 30 GB. Then it mounts normally.
Ok now more then half of you will say that this is fake card or smth. But i downloaded H2testw program and checked my card. Everything is fine with it. The program wrote 32 GB of data and verified everything. Its just problems with phone reading SD card. Anyone can help me ?
Hmm........
So noone has any ideas ?
Check your phone for firmware updates that might raise it to the 32 gb ceiling. Maybe there is a Cyanogen 7 update that will take care of this for you. Also does your phone support SDHC cards?
SD Card Not reading correctly
If you haven't done so, you might want to check the specs of your device to ensure that it will accept 32GB. Some devices top out at 8 and 16GB respectively.

That, and I would upgrade to the latest nightly of CM7.
It is probably not "32gb" "Genuine" memory card.
I've purchased the memory card couple months back and
It says "16gb" when I put musics/videos in the memory card, it was unreadable and unplayable. I think it had actual memory of "2gb", so yes, I've been scammed by Chinese people =P.
I recommend you to check your actual memory by using this program
"H2testw"
I have gone through three 32gb cards now and none seem to be working. I try to swap the contents of my 16gb card to the 32gb card and the data gets corrupted each time. The data on the 16gb card is fine and I can transfer it to my PC drive, thumb drive, and even a different 16gb sd card and view all the files with no problem. But everytime I try to transfer it to any of the 32gb cards the data gets corrupted and the transfer fails. I have formatted each card with the panasonic card format software (ver. 3) and it still doesnt work. I have tried different format options and I have even tried to format it with my EVO and still no go. Any suggestions would be appreciated.
Thanks,
The Xoom's SD card slot doesnt work on stock Android 3.0/3.1. If you rooted to get an OS with an operational card slot, it is possible that the root did not install correctly.

Trying to understand...you are saying that the file transfer has failed from 16gb to32gb when using PC to transfer...not a Xoom issue yet? Have you just put a few files on the 32gb card and checked it in the Xoom? It sounds like you've done everything right...are you sure the cards are good?
I am rooted and have been using the card slot for some time.
I have tried to transfer the files by several methods. PC -> Card, PC -> EVO, PC -> card reader, PC -> Xoom, and vise versa. Nothing worked. I have tried putting just a few files on and it seems to work, but when I try to put all the files (about 9gb's worth) the info starts to become corrupt. I suppose its possible that all three cards are bad, but I have to think the odds on that would have been pretty high. The first card was a class 10, the second and third cards were class 4.

I hope someone with experience with a 32gb card jumps on this...I've never used anything larger than 16gb. It just doesn't make sense-have you tried transfering smaller chunks of data at a time? Anyway, I hope you can resolve this...if you do, please share. Good luck!
It really does sound like faulty cards. Where are you getting them from? It's well known that sd cards bought from eBay or Amazon Marketplace are more than likely fake.
For example, I bought a 16GB card from a guy on eBay and was only able to transfer 2GB of data to it then the card corrupted. I later found out that people are re-badging smaller cards to look like bigger ones. They also spoof the size on the card itself so it reports as a larger card when plugged in but they only take up to their former capacity before corrupting.
All were bought from Ebay so that would make sense. Where do you suggest buying the card? My local chain stores do not carry anything larger than 16gb right now.
Yeah, hopefully you can get your money back for them. I did but it took a little nagging.
I buy mine from ebuyer.com but that's a UK site so if you're elsewhere maybe Amazon (direct from Amazon only tho as the Marketplace is just like eBay for fakes) or maybe Best Buy? Definitely go to a reputable dealer anyway.

I either buy mine locally, or NewEgg ONLY.

Hope this helps!
Are you sure your computer isn't putting the usb to sleep while it's copying?
Just thought I should let you all know about my recent experience with this microSD card.
The Part number is SDSDQY-016G-A11 or SDSDQY-016G-A11A
I bought one from my local Best Buy after finding the item was marked down from $49.99 to $17.99. At first, my initial thought was "Done!" I took it home, opened the package and began transferring everything from my 8gb card to this new 16gb class 10 card.
Now, here is where the problem starts. I do not know if I did not take the necessary prerequisites for this particular card, but, after about an hour of just basic copying of data to the new card, I was struck with a CRC error and the card forced ejected itself from the USB host. I removed the card and put it back in to see what happened and found a corrupted directory from the last thing the card was copying. I couldn't access it or delete it. I couldn't copy anything into the card either. I tried formatting, to which it would complete the operation with a "This card could not be formatted." message at the end. I tried downloading different partitioning software to delete the partition, format the unallocated space and create a new partition to which I was "then" greeted with a variety of "This card is locked/Failed Operation/Space cannot be formatted/Partition could not be created." I gave up. I went back to Best Buy and exchanged the card for a new one. I thought "F*** me right? I got lucky with a bad card."
Nope.
Same thing with the new card, except it happened within 5 minutes of copying anything onto the card. This time around, I decided that I am not going through all of that again and returned the card.
Again, I do not know if I took all the necessary prerequisites before handling the card, but, to my knowledge I do not think there could be anything.
Instead, I jumped over to Hhgregg and found a different model SanDisk 16gb microSD card. I was able to copying over everything over to that card the first time and without a problem.
Also, in case it's asked, the phone did pick up the card initially before anything was copied. After the problem's arose, the phone refused to mount the card at all.
So, if anyone was considering picking up this card, its up to you what you want to do. Just Beware.
I found that the SanDisk USB device/ other SanDisk Adapters was causing errors in the 15 or so misc cards I put through it. Were you using it? or was it in your phone?
I went with the 64GB SDXC and no issues since.
At first I used the supplied adapter which is when the first card gave out. The second card I used a different adapter. A USB based one and it still gave out but much faster. Initially I tried with the card in the phone, but it kept force ejecting itself from the USB host as soon as I started. I thought it was the cable at fault.

I have the same problem i purchased 16gb ultra yesterday and today i m unable to format this card in NTFS system it formatted succesfully in fat32 bt the speed i get white transferring any file is jus 3.5-4 mbps olease help any solution for that??
I have a 7 months old SanDisk ultra 32gb and it's still very good. I have better speeds when copy inside the recovery than inside the rom.
Did you report it to Best Buy?
So there seems to be a big misunderstanding on how and what kind of sd cards can be used in the note 10.1.
I have seen a lot of posts talking about whether or not you can use a 64gb sd card, whether it needs to be formatted, partitioned, and I have even seen posts describing a 2gb file limit with unformatted cards. I have good news!
These people are all completely misinformed!
The truth is you can put an unformatted, unpartitioned 64gb sd card into a note 10.1 out of the box! (Both the chip and device require NO MODIFICATION)
I have completed this successfully on three note 10.1's GT-N8013 (us variant of the note) both on ICS AND JB.*My success came with a San Disk 64gb Class 10 sd card.I have also used san disk 32gb non class 10.*Both cards require ABSOLUTELY NO FORMATTING, OR PARTITIONING TO WORK OUT OF THE BOX!!!!
Oh and 2gb file size limit per file is bs in regards to any sd card I have EVER used!! Downloaded a 5 and 8 gb file simultaneously last night.
Enjoy Your Droids now with extra memory!!
Oh and look up about how to switch internal storage with external storage. (It enables you to use a 64gb sd card for your apps.. more games!!) Max from rootgalaxynote.com has a guide on it. Theres other guides to but max writes fairly intuitive guides in my experience.
