32GB SD card issue w/2.3.3 resolved

I recently upgraded my phone to 2.3.3 from 2.1.
After upgrading, my phone no longer detected my 32GB SD.
I spent a lot of time researching the issue and found that most people just went to a smaller card like I did.
I went out and bought a 4GB card.
After loading my phone up with apps and audio and images, 4GB was not enough.
So, here is how I resolved this...
I downloaded HPUSBDisk.exe which is an HP USB format tool.
Copied the content of my 4gb micro to my PC/Laptop.
I inserted my 32GB micro SD into a "micro sd USB adapter"...
Format the SD using the HP USB format tool (FAT).
Copy the contents from the 4GB to the 32GB.
When I placed the 32GB into the phone and powered it up it was now recognized.

weird, I own a 16GB card and never had problems with 2.3.3
actually never heard about this problem until today

16 GB are not really a issue.

I use a 32gb from Kingston and have no issues. ??? Think maybe it's not the memory size that is the problem. Maybe it got corrupted? I had that problem on a smaller card on a round of back to stock while playing around with ROMs and such. Formatted it on PC and all was fine... think it was 8? Was a while a go. But I've heard of it happening while updating, read about it after I had the issue with the card that came with my x10.

1. X10i officially supports cards by a capacity no more than 16 Gb. However, most cards 32 Gb work normally too.
2. A card can be formatted by standard facilities of Windows, it is important only, that a clustersize was 32 Kb

+1 to OP
thank you

I have an X10a... but whatever.
When I flashed my 32gb SD using Win7, regardless of the cluster size, it would not work in my phone. Period.
I am NOT the only one who has had this problem nor am I the only one who found success in my method.
The 32gb I have in my phone right now, was formatted using the HP Tool at 16kb...

FYI:
"Memory Phone memory up to 1GB
microSD™ up to 32GB, 2GB included"
(obviously the original specs, mine came with 8GB)

Yes but quite a few cards seem to have bad compatibility.

I'm curious if it's a certain class of cards that cause issues, or if it's certain vendors or brands? Do certain brands format them different and that causes the issue?
I researched what class was supported and bought a brand name (Kingston) that isn't high end but from a reputable business so I knew it wasn't fake. Bought a 32gb class 4 Kingston from Tiger Direct, popped it in and it worked fine. I put it in and tried it before transferring data to it.
I'm definitely not discounting the issue, but finding out WHY the issue is there is what I'm curious about.

i heard SDHC work the best but i'm idk the difference really, all i care about is the memory on the card

MY 16GB class 4 & 32GB class 6 KINGSTON both worked very well with no issue's.

Having the same problem!
I just upgraded my X10a to 2.3.3 and it's not detecting my 8gb SD card, I re-intalled the 2.1 android and the card worked fine, then I upgraded it again to 2.3.3 and formated the card, didn't work... I don't know what to do now!

Having a similar problem!
Hi, I've been having a problem with mi 8GB SD card, the thing is that I just Upgraded my X10 to 2.3.3, but it's not detecting the micro SD, it was working fine till I did the upgrade, so I took the card and plug it into the PC, it is working, then I tried changing the fortmat, didn't work either, so I changed it back to Android 2.1 and It got it working again, I tried one more time to upgrade to Android 2.3.3 and the problem persists, all the apps and features are working just fine, but the phone it's kinda useless without the microSD...
Anyone that knows what the problem might be, please reply, cuase it's very frustrating!!

The stock 8GB card in my x10 died quite fast.
They get scratched underneath easily.

Hate to bump up an old-ish thread. But I came across the following article and the pertinent quote from it is "We tested this card on some phones including Motorola Razr and Samsung Galaxy S2 and even on a year old Sony Ericsson Xperia X10 and it works fine"
So it looks like this old dog was still able to use a 64GB micro sdxc card.
But at 110$ USD (cheapest I've found so far)... might not be worth it yet.

SDhc problem.

Hello!
I just got my new SD HC (32Gb) card for my htc HD2 device, but im getting weird crashes when i just put some Gb of for example music. It deletes some of it, or changes it to thousands of 0byte weird files..
Can someone help?
/card wasnt expensive and its not Kingston or so./

I'm really not certain about this, but their a limit on the size SD card our hd2's can support. (Either 16 or 32gb which is what I'm uncertain of) try formatting your new SD card into two 16 gb partitions and then see what happens.
Hopefully either that helps or someone with more knowledge than I will comment and give you a better answer

Well the limit is definitely not 16gb because I have one of those and it works fine in Android but it for some reason cannot boot SD Android. Also, if I'm not mistaken MarkAtHome (I've seen him in many of the NAND threads, especially NexusHD2) has a 64GB SDXC card as he was posting something about that a while ago. He'd have to confirm though.

Where did you get your memory card?? You son are a victim of false advertisement. I purposely purchased a "cheap" 16GB sd card from ebay and it wasnt even bigger than like 300MB. There are ways to fake the memory size, and thats why when you try to put the music on your card is says its not there because there truly isnt any physical memory available. And also why it gives those weird readouts. Sorry to bust the news :/

According to HTC's website, the HD2 can support up to a 32GB SDHC (class 10 i believe)

Yes. You set up two partitions 32 gb each.

There have been threads discussing how certain sd cards do not perform well in android devices, including the HD2. It has to do with some of the access times the cards are rated at.
I have tested a 32gb patriot class 10 card in the HD2 and samsung vibrant that made both phones freeze and run terribly slow until the card was removed.
Sandisk cards run flawlessly in the HD2 and I have only been using them for the past year, including a 32gb and a 64gb SDXC. The 64gb must be formatted as fat32 inside the phone before it can be used, but the full 64gb is available.

I agree with elesbb. Infact the same thing had happened to me about 4 years ago. What they do it put a memory hack in the SD card fooling it to think there is more memory. I would say if you bought it from ebay contact the seller first and
tell them you think it might be fake and you wish to get a real card asap. If they don't send you one or sound like they may be un-willing to then you should report them. Here's some information found on ebay's site about fake memory cards.
If you bought it from a different online seller you should still contact them about it and say you did some research and believe you recieved a counterfit item. In the link i shared above there are a few examples of how to spot fake cards including some pictures if you go through the links. I've read somewhere that if you have a sandisk and the class rating is in the corner then you more then likly have a counterfit one. Sandisk's class ratings should be centered in the middle of the SD card.

Okay, i've just sent email to him, hopefully he will just re-send me new, (working..?) or give money back!

MicroSD card ejected when listening to music...

Hello everyone.. I've been a lurker of the forums for the last 3 or so years, and... Well finally decided to make an account as I really can't find any help anywhere else, plus you guys are awesome, really
I'd like to make it clear first that my problem is unrelated to similar threads as I will explain...
My S4 spits out my SanDisk Ultra 32GB (Most threads point to 64GB) MicroSD card whenever I play music, irrelevant of player.. (Samsung default Music app, and PowerAmp Pro.) Usually when launching, it is unnecessary to play a file.. Both ejecting and re-inserting the card manually or restarting the phone does absolutely nothing...
I've had this issue since firmware release AMDE, though it was tolerable as it only occurred once a week or so... Since EMK8 however my phone is absolutely useless when it comes music as this occurs when launching any music app...
I should point out, I've tested the card further on an i8190 using benchmarking and SD testing apps as well as the 2 music players I use on my i9505 and it had no issues what so ever...
PS: Suffice to say I did a wipe with every firmware upgrade....
I'm assuming this is most likely a device issue, but I tripped Knox Warranty to 0x1 when rooting the day I got the phone (I got it when MH8 released, but used the old firmware for a few hours..)
What can I try? Has anyone with the same issue found more luck with another music app?
Thank you in advance

Try to format the sd card.. and if you want, format it from the phone itself.. Good luck

Thank you, though I don't think I really wanna touch that.. Seeing as if the card decides to unmount in that way it may end up worse, I think....
I've been searching a bit more and found a thread on another forum, it appears that the 32GB SanDisk Ultra card is giving problems with many Samsung devices, maybe I was just lucky with my old S3 Mini... I guess it's time to go back to Lexar cards again for me...

Well, I've made a couple of new discoveries and am glad to say that the issue has been resolved! It did take a bit more investigating to find out the cause, however.... Apparently the issue occurs when using the early 32GB and 64GB SanDisk Ultra cards on Samsung devices whilst having the 'bloatware' version of Dropbox installed... Why? I have absolutely no clue.. But since removing Dropbox everything seems to be working okay.. Around 5 hours daily testing over the last couple of days and haven't had a single eject in the process... Admittedly the cause seems to be completely unrelated.... But, alas... Hope this may help someone with the same issue in the future.

Note 3 SanDisk 64gb SDcard owners BEWARE!

If you own a class 10 SanDisk Ultra micro SD card for your note 3 then BEWARE!! I don't know what causes it but it will cause a bootloop for some reason...
If that happens, take battery out, take SD card out, boot up phone, go into settings>wifi>Hit menu button and choose "Advanced> and uncheck "always allow scanning". Power off phone, put SD card back in and boot up. No more bootloops! I heard this happens to 32gb models aswell.
Some people did factory resets and it still kept happening, so just uncheck always allow scanning.
Even if you own the card and never got a bootloop, just uncheck it just to be sure, it's not really important, and you won't have to worry about any bootloops. And yes, this happened to me while i was Stock rom and kernel unrooted, you never know.
Hope i helped!! Remember UNCHECK ALWAYS ALLOW SCANNING!!! IT'S BAD FOR NOTE 3'S WITH SD CARDS!!

I don't know, but my old Note 2 fried my 16gb SD card. Samsung phones have a reputation for frying/corrupting perfectly good SD cards after long periods of use, i don't know about the new Note 3 though, probably.

I reformatted my to fat. No issues.

Why on earth would scanning Wifi Access Points cause a SD card to cause a Bootloop? I think you are confusing scanning the extrenal SDCARD with Scanning WiFi Access points. While there IS the possible chance that this somehow helps a reboot issue, the two items have ABSOLUTELY NOTHING to do with one another. Somewhere along the line someone confused MEDIA SCANNING (a fact of life with android and external SD Cards) and Wifi SSID Scanning, and true to internet style this piece of misinformation is EVERYWHERE.. I just found the SAME, WRONG information on someones Blog: http://www.etradesupply.com/blog/solve-samsung-galaxy-note-3-problems/ and guess what? HE states he got the info from... XDA... Its not in any way accurate, .. Please don't post information like this, because you saw it somewhere else... Google just published a report that shows that some 70-80% of all internet content is copied from somewhere else.
By the way, I have been running a 64 Mb. Class 10 SanDisk Ultra micro SD from release day for the N900A with zero issues, for what it's worth. I am well aware of the issues people have had with SD cards. I am simply letting people know that there is no logical reason the WiFi scanning would have any effect on the issue, when it's media scanning that people are trying to prevent.

Wow, lucky guy!!!! You got it working on the first day Sorry if you think it doesn't work or doesn't make any sense, or whatever, but it worked for me, and for my cousin on the Canadian Rogers Note 3 SM-N900W8, and probably a lot of other people too, so i'm just putting this thread out just in case someone (Like me) got a bootloop right after they put their SD card in, and trust me, you are not happy to get a bootloop the first or second day you get your phone.It is NOT pretty, well actually, the Note 3 is pretty pretty, but the bootloops are NOT pretty.

Her phone has no issue with 64GB Sandisk, but I have had issues with two (took first one back before 15 day period was up) Notes until I followed this same advice from another site. Not sure why it works. I just know that it does. I would not discourage people from posting advice if you aren't experiencing the issue. You could stear someone away from a solution that might just work.

One time on my Note 2 my 16 gb (not Sandisk) SD card got fried and lost everything in it. I guess Samsung devices just don't like SD cards.

That's weird I have a 64gb card and have never had that issue at all. Only problem I ever ran into is that S'S didn't support then at first. But other then that never had a problem at all.

It seems the common thing here is that all cards are class 10. Is it possible that a class 10 card is too fast? I know I never paid attention to class and most of my cards with no issues have always been class 4 cards at 8 or 4 GB.
It to could be possible that this phones hardware can't address 64GB correctly. I don't recall seeing documentation that said it supported above 32GB.

By the way, I have been running a 64 Mb. Class 10 SanDisk Ultra micro SD from release day for the N900A with zero issues, for what it's worth. I am well aware of the issues people have had with SD cards. I am simply letting people know that there is no logical reason the WiFi scanning would have any effect on the issue, when it's media scanning that people are trying to prevent.

I'm the person that found the original workaround as posted here:
http://forum.xda-developers.com/showthread.php?p=46446775
I validated the workaround several times. It has been copied or quoted at least two times and noted by numerous people that it actually works.
It may be that particular sd cards in combination with memory initialisation and particular OS components being loaded and/or initialized upon boot causes the problem.
Not all defects in software and/our hardware are 100% repeatable across all devices with the same basic configuration.

Problems with 64GB SD card

Hi.
I recently bought myself a 64GB class 10 Sandisk card from Amazon which I was going to use with my Note 3. When I first put it in I formatted the card in the phone. And then I took a few pictures and videos and all seemed to work fine.
The next day when I was taking some photos it suddenly switched over to the internal memory and I got the message that it was unable to save to SD card. I checked the gallery and the last picture i took was corrupted. So after this I tried taking the card out with the phone turned off, put it back in and started the phone. I was able to take some photos but when I was going to record a video it corrupted the file again.
After this I put the card in my PC and did a full format to exFAT and tried filling all ~59GB with pictures, videos and other files and from what I could see no files were corrupted.
Then I formatted it once again in my PC to exFAT and put it in the phone. After a few pictures it once again corrupted the files, even the camera app (default one) crashed at one point. Formatted the card in my phone again but same problem.
I then tried the card in my Gopro camera, first formatted it in the camera then recorded several videos in both 4K, 1440P, 1080P and took several pictures and everything was fine.
I'm not sure but the card seems to be working in other devices. Do you think the problem is the card or my phone? Before this I've used a 16GB class 4 Sandisk card with no problems at all.
Any tips on what I can do?
Thank you in advance!

It's stock and not rooted.

Could be a bad card, try unmounting and mounting the card again and see if that fixes it.

Yeah I've tried that a few times as well and it didn't help. But as I mentioned the card seems to work just fine it other devices. But in my note 3 files get corrupted.
Do you know of any program or any other way to test/confirm that it is the card that's bad?

Actually I do. I have used the HP SD Card Format Tool to fix cards in the past and it has worked pretty well. I also found this thread here on XDA that references it as well.

What write and read speeds were you getting in the PC? The Sandisk models are among the most faked models and that is by far the most frequent problem that I have seen. There have been also certain batches with problems, but Sandisk is always replacing those almost no questions asked if it is a genuine card.
I also have a 64GB Sandisk Ultra which was used about 1 year in my i9300 and now almost 4 months in the N9005 and so far I have never had any problems (but I am keeping an eye on the 128 GB models if those seriously go down in price).

I just ran a test in the program H2testw 1.4 and got these results:
Warning: only 60872 of 60874 MByte tested.
Test finished without errors.
You can now delete the past files *.h2w or verify them again.
Writing speed: 8.49 MByte/s
Reading speed: 17.5 MByte/s
H2testw v1.4
So the reading speeds seems fine I guess, it also filled the card with files and verified it.
I would assume that if it was a fake it would have slower speeds and maybe only 2-4GB of space?
I am using the SD card adapter that came with the SD card, and then I put it in a USB SD card adapter in a USB 2.0 port.

Is anyone else having problems with 64GB SD cards? It's as if my Note 3 wasn't compatible with the card since it is working fine in other devices and isn't a bad card according to the test I did.

Sorry .deleted.

Sounds like a hardware fault on the Note 3... I've been using both a sandisk and a samsung 64gb class 10 card on both my note 3's with no problems from the start...
Never had a problem with file corruption....
sdhc and sdxc are 2 different formats - sounds like you could use a 32gb sd card fine but it has issues with the 64gb sd card.... 64gb sd card is the newer format sdxc....
Unfortunately here you hit a snag... Unless the samsung sites list 64gb as ok to use on the Note 3 then they may just say to to warranty repairs.... If 64gb is the listed size (generally "up to ") you should have no problem. It does sound like your card reader doesn't like sdxc... Unless you can get your hands on another 64gb sd card to find out you not be able to use your 64gb sd card...
