I don't have a samsung card to try, all sandisk specifically for Android. I picked them up while I was in Malaysia this summer for about $15 per card. I have been using them in my T989, tab 2, and blaze with no issue. They are the red and gray ones with the Android on the package.

I have tried the format in computer and then format with phone but still have the issue after about an hour or so. I think it is software related but don't want to root yet to see if that fixes it. Has anyone that is rooted had this issue?

The same error with Sandisk 32G Ultra. :eek:

Having issues with my SanDisk 64GB class 10 card. Formatted to exFat and phone was seeing it it but now the card seems corrupt cause my PC doesn't reconize it now?
[T-Mobile Samsung Galaxy Note II] limpysmalls:
Has anyone that is rooted and running a ROM that is not Touchwiz having the same issue with corrupted SD-cards? We need to narrow down if it is a hardware or software issue that we are having.

I formatted mine to Fat32 on my windows 7 computer and then formatted it using the phone. It started acting up right away but has stopped unmounting itself, I think. I moved some music back on it today to see what happens but so far I can live with this since when I wake the phone the SD-card is there and I can access it. Before it was unmounting itself every few times and I would have to go into settings to get it back.

My son's phone has a 16GB class 10 SanDisk I should try for a few days to see what that does.:confused:

Here is a link for an excellent formatting and partitioning Tool. It's free and I have been using it for years without any issues.. I learnt of this Tool from very knowledgeable xda members.

Hope this helps, but I've used many different brands of miniSD cards and particularly

with SanDisk brand, it is best to just put it straight into your phone without reformatting.

I have the Note 2, SIII and my wife the SIII. Both SIII's are using the same SanDisk 64GB Class 10 card.

With my phone I put the SanDisk straight into my phone without reformatting. However, on my wife's phone I reformatted (Fat32) on the PC and reformatted once in the phone. Her SD card started acting up.

Contrary to what many people thought including myself, I thought the cards usually all came in Fat32...however, I come to find out the SanDisk's come formatted in exFat, which was a complete SERIOUS?! moment for me. I guess the 'newestest' phones like the Note 2 are exFat friendly?

So my theory is with SanDisk, just leave it alone and put in the SD as is. (For newer phones) I can think of a hand full of reasons of why I think SanDisk's crap out if formatted, but I'll leave the speculation to rest.

Good Luck!

(btw: The best cards I've used are by far Samsung, PNY and A-Data. What they all have in common is that the chip component itself is all made in Korea. Well obviously Samsung is Korean...but I'm referring to PNY and A-Data.)

Cheers
[T-Mobile Samsung Galaxy Note II] iunlock:
I've had ZERO issues with Samsung Cards. In fact, Samsung, A-DATA (parts by Samsung) and PNY are the most reliable and fastest (read/write) I've seen.
[T-Mobile Samsung Galaxy Note II] limpysmalls:
I used that to format the card with the same results, it is a great program and I have been using it for awhile.

From what the last few post are saying is that the Samsung Phone only works with the Samsung SD-Cards. That is interesting. I am a little pissed since I just had invested in 2 SanDisk cards which work fine with my T989 and my Tab 2. I would have thought that a phone that can run 64GB cards could also run 32GB cards correctly but it doesn't seem to be the case.

Any input from others that are not using SanDisk CARDS that are 32GB and above would be great.

I had hoped the update might fix things but no luck.
[T-Mobile Samsung Galaxy Note II] predation:
i think it maybe a loose connector to the sdcard slot as discussed http://xdaforums.com/showthread.php?t=2035854

possibly a hardware problem.

but since this issue doesn't seem like its solved, i guess i'll just stick to using the internal memory and forgo the sdcard until there is a definitive answer. :(

oh, for those brave enough to try and "re-seat" the connection, here is a youtube of the teardown.

seems easy.

http://www.youtube.com/watch?v=UT-2zrZ_aNo

for you guys attempting this route, please make sure that the connection isn't seated correctly, because if it is, then its something else.
[T-Mobile Samsung Galaxy Note II] PoorCollegeGuy:
I had a 32GB class 10 sandisk that completely died a couple weeks ago. As in wouldn't work in any other device or computer.

I'll try that hardware fix in the coming days. Has anyone dropped their phones at all? I have a case on mine but it still gets bumped to the floor. Could it be possible that the connection between the sd card and mobo is weak already. Most phones can take several drops without something like this happening, but if Samsung cheaped out on the connector ribbon, then a couple of not-so-bad-drops could be loosening them up.

I powered the phone off. Plugged it in then turned it on. Then turned the screen on one off a few times, then unplugged it.

You do have automatic photo backup set up on Google+ and Dropbox...right?

[T-Mobile Samsung Galaxy Note II] heiNey:
yea, i agree.

good thing i have G+ and dropbox instant upload, otherwise i would have lost everything.

im not sure how to restore the pictures from G+, but at least dropbox just saves a copy to my dropbox folder that i can just copy back to the sd card.
[T-Mobile Samsung Galaxy Note II] BACARDILIMON:
I here so many people having issues. I took my 64gb from my galaxy s2 and just put it in the note 2 and been working perfect. I even unmounted and then remounted to back it up just in case and still working. In the s2 roms sometimes the sd card reader files would not flash right. Try a reflash or do sd card pull and install in ur pc and check if the info is really lost.

N7100 here. My card (SanDisk 32GB Mobile Ultra Micro SD (SDHC) Card - Class 10 UHS-1) was working fine until 2-3 days ago when it started to get unexpectedly removed. Tried 2 different cards (8GB and 16GB) and they work just fine. I even flashed stock 4.1.2 Jelly Bean, but that didn't help.

I guess there is some incompatibility between Sandisk cards and Note 2?

I'm returning mine and will get a Samsung one probably.
[T-Mobile Samsung Galaxy Note II] kabuk1:

[T-Mobile Samsung Galaxy Note II] Harry Tuttle:
Same issue here. ..

Funny sd unmounted appeared yesterday and is on going today,using a Scandisc 16gb class 6 or 8. Like someone else pointed out i was listening to music off the card when the message popped up, my belief is that it is software not hardware related. This card has been around the block; from a HTC Universal, G1, and a couple of Symbian phones as well as a N900 so I think it is software, my 2cents.
[T-Mobile Samsung Galaxy Note II] limpysmalls:
I swapped my card intoy wifes blaze and it started acting up 2 days later. It might be the cards. Had no problems in my SGS 2 or Tab 2.
[T-Mobile Samsung Galaxy Note II] talox:
I have the multi window update and still have the problem.

I have been running for 24 hours though without seeing it again.

Here's what I did.

1 - Go into the Samsung browser (the one the phone came with) and go:

​

Menu - settings - advanced - default storage - set it to device.

(if after a while you see that it has reverted to memory card, then it means the memory card was remounted – at least this is the way I check)

2 - Back out of the settings - open up the tabs from the top right and close every tab so that all you have left is the "about:blank" page. press the home button from here.

(make sure you leave it on only the about:blank page every time you leave the browser)

3 – Disable anything you have that automatically toggles the Wi-Fi (e.g. tasker, locale, any other app.) If it toggles the Wi-Fi, disable that app.

I'm not sure if it's the browser or the WiFi causing problems for me, I just did both at the same time.
[T-Mobile Samsung Galaxy Note II] predation:
for you guys having problems.

are you running explorer apps?? ie. astro, file explorer etc????

maybe the stock "my files" app is conflicting with the play store apps???

try disabling the "my files" native app or uninstall the play store apps??

i'm thinking of sucking it up and getting a Samsung 64GB Extreme microSDXC Class10 UHS-I for $70 at a local store because it looks like the samsung cards aren't having issues.
[T-Mobile Samsung Galaxy Note II] derichio02:
For what its worth I am having the problem with the Sandisk 32gb as well. I have also noticed that when this happens it causes the internal storage to report incorrectly in the Pictures section. Before my factory reset the pics section in settings-->storage said over 40gb. I just factory reset and I have no pics or vids on the internal memory and its reporting over 400 megs. The totals don't even add up. Take a look.

After the factory reset Pictures said around 25mb then when I had the message I looked and it said over 400. Seems like software to me. Maybe being incompatible with the card

It seems as if the problem is with Sandisk 32GB class, as I have the same problem and I exchanged it from amazon the new is behaving ok now. From what have read, it seems the batch was faulty and new batch with fixes has replaced the old one since december. I tried my sandisk 16gb and no problem with that.

Another one to add to the statistic. 32GB SanDisk Ultra Mobile micro-SDHC Class 10/UHS-1 card completely and totally dead. Purchased mid-October and was used in a GALAXY S III and subsequently the Note II. The phone said that the card was unexpectedly removed, attempted to reseat it to no avail, tried in two different card readers and it doesn't show up at all to the operating system.
[T-Mobile Samsung Galaxy Note II] OwenW71:
Well, our theory that it was a bad batch has been disproved. SanDisk sent me a replacement and after about two weeks it has started doing it again. Before I lose anything, I'm backing up all my files and I'm going to buy a Samsung card.

This is ridiculous.

[T-Mobile Samsung Galaxy Note II] burnie022:
I also am having problems with my 32 gb SanDisk class 4. I started getting bad battery life and high drain from Android.process.media then started noticing sd unexpectedly unmounted messages about 2 weeks ago. The card is about 6 months old. When I'd remove the card the drain was gone and battery life was good. I tried cleaning up some files from the card but same problem then reformatted the card and added my files again and no difference. Now I added the same files to my 16 gb SanDisk minus a couple backups and game loft games and no more unmounted messages and the battery drain is normal.

I think that every time the 32 gb SanDisk would unmount Android.process.media would scan the card and that's what would cause the battery drain because there were a lot of wakelocks from media. The card is probably bad. I'm going to return it and try to get a new one though warranty
