4gb mini sd cards, anyone tried one?

hey, I've seen some ads around for 4gb mini-sd cards, most with totally unknown brands. I'm talking about the non-sandisk, non-HC format ones. Has anyone tried these in a tornado-type device? Do they work?
thanks!

I did - be carefull - might not work!
I ordered and got my 4GB card last week (mobymemory). While the card is recognized in the phone, my phone keeps crashing ever since. When i put in my mobymemory 2GB card, my phone doesn't crash. I also noted that the card is getting corrupted quickly in my QTEK 8310 (using chkdsk in a cardreader to confirm).
I mailed HTC and they said that 2GB was the maximum supported by my smartphone device. I stated that on their website they claim miniSD up to 12GB was supported, but they say that is a typo on their website they will correct soon.
I also mailed mobymemory but haven't got any response yet. Still it might be that i just got a faulty one.
I am now on my latest experiment. I partitioned the card in a 2GB (2048MB) partition and the rest (1.9GB); my phone recognizes the two storage cards (second is now named 'storage card2'). However, i already had my first crash quickly afterwards (using navigation).
Right now, i am formatting the card to FAT instead of FAT32 (still partitioned).
Running out of options, will keep this thread updated.

thanks for posting about your experience, and good luck!

In the end it kept giving errors and i requested an RMA which they accepted.

[HEADS UP]SanDisk Ultra 16gb MicroSD Class 10

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?

Your SD card likely isn't the problem

I was going to post this in response to a couple of people in the development sections but my post count is too low so I'll post it here instead.
The SD slot in this phone seems to have an issue with corrupting SD cards, I've had to format both my old and new SD card multiple times with this phone as it becomes unusable every few days. I'm not versed enough in hardware to know if this is a bad connection between the SD slot and the "motherboard" of the phone. I've seen a number of people have their SD cards go bad with this phone and I assume that means we had a manufacturing issue. It would be really cool if a hardware hacker experiencing this issue could take a look inside and confirm whether or not the hardware is connected correctly.

Well, perhaps there's a high number of bad readers....
I've had the same card in my Q since the day I got it (mid-September), no issues.

Mine wouldn't read the day I swapped up from My Epic 4g Touch to This phone, So I popped in an sd reader backed up my data then let the Moto format it, no issues sence

Curious to know what class of card you guys are running. I've been running a Patriot class 10 but my previous was a class 4 without branding that came with my old Transform.
I'm really hoping that I just had my old SD card die at a bad time and that my newer SD card was just sent bad. Today I couldn't get the card to read from the SD slot in my computer, and it would not be cool if my phone caused it to become that way.

Class 10 Maxell
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2074251
No issues here. I tossed the crappy class 2/4 that shipped with my Epic long ago.

Well I found an extra class 4, 2 GB SD card lying around the house when I was cleaning today. It may be that the local shipment of phones was bad, so if this SD card goes on me then I'll try exchanging the phone in another town just to be safe.
Just out of curiosity does anyone know whether Sprint orders enough phones for replacements with their original shipments? I'm not from a very large town so I'd imagine they would keep replacing with phones from the same batch.

I've got a Samsung 32GB class 10 mSD.
Nearly everytime I reboot my Photon Q it says "SD Card is damaged".
Go into settings, Mount SD Card once or twice and it works.
I've read, that other Android Devices have also problems with that size of SD Cards. (Google)
I had also problem in recovery restoring a backup, the restore process didn't went correctly
(said that everything was fine), had to use my 2GB mSD, which worked nicely and the backup also.
So I think it's an android/kernel issue than a hardware issue.

I have noticed that I get the corrupt sdcard error everytime I try to use the "mass storage" or "media device" setting with Windows.
I use Ubuntu 99% of the time and leave it connected in "camera" mode, have never had that pop up like that...
I usually just use ADB to copy everything anyway so I do not miss the "mass storage" mode at all.

Just had a 16gb class 10 microcenter branded card go belly up on me. Phone just all of a sudden said it was removed and now nothing seems to recognize the thing. The mount option is completely greyed out, and does the same on my note 10.1 if i pop it in there.
When your cards have gone did they completely disappear and refuse to read?

I wonder if it's the c10 cards...
You guys really shouldn't be using high class cards in a phone - there's really no benefit, as phones use SD card's very differently from camcorders or cameras...
On my ooooold phone, anything above Class6 was bad juju. I have always had class4 or lower cards, no fried cards (yet... lol)

kinda what I am feeling too. Not sure what class card I have but it was just a cheap 32gb from wallmart... Only had that error pop up once with this one though, and that was after trying to use usb storage.

Class 10 shouldn't make a difference to a device. The class/speed only comes in to play when transferring data from/to a computer, which will be faster on Class 10 vs Class 4 or 6.

As best as I can tell, thats a negative. Ive been running with a 32GB class 10 since around when the phone was released, and Ive had no issues. Quite surprising on its own, seeing as I abuse the poor thing. True that class 10 arnt useful for the phone specifically, but some shops only carry class 10 cards.
@hfase
I dont seem to have any issues with mass storage, with ~1GB written a day. Im quite curious as to why some people have this issue.

Maybe it's all down to the quality of the actual card itself?
Perhaps the cheaper no-name / off-name brands have a much higher failure rate....?
I'm not really sure, short of actual hardware issues on the device.

AW: Your SD card likely isn't the problem
Well here is my experience:
I am using a new san disk 32GB class10 micro sdcard. It was never format ed/ used before. The q itself formated the disk.
I have had no problems until using the twisted asanti prebuild
Version. Since then I only got problems with the qu saying the sdcard would be corrupt, after reboot. ( I expected some additional wired things, like the currents widget, which I deleted before reboot reappeared). So I would suggest it is an error in un mounting the sdcard before shutdown, which causes this failure.
Since I usually do not reboot the phone expect for flashing new roms, I had no trouble since then.
Hope this might help to further circle the problem, and maybe find a solution for this.

Since CM10 I haven't noticed any SD-Card issues, but I have the feeling, that there are some issues, which aren't detected.
In the last few days my CM10 was acting weird.
1. The gallery (together with the camera app, 2in1 app) disappeared in the App Drawer (was still in /system/app) and didn't appear again after overwriting gallery2.apk again.
2. The Google Weather App had a graphical issue, so I was sure, that there was a flash issue by restoring ASA14 and flashing CM10 (from SD-Card!).
I solved this issue in copying the nandroid backup and CM10 to the phone and flash it from there.
I have tested my SD-Card in my external cardreader, it had no issues in doing so.
My guess is, that the SD-Card needs more power than the Photon Q can give and is losing some read/write commands.

I think This may have hit the nail on the head. I have had a couple cheap discount cards die but they really died. Cant even read in the PC and one even got really hot when plugged in. Got a good branded card from amazon and havent had a problem since.

I've used better Samsung and Sandisk cards and have had this issue. It just randomly wipes all my data and creates the LOST.DIR with it all in there, but file names are all renamed and would takes years to sort through and try to figure out what is what. All my photos, music, etc.. were basically gone then. It didn't matter that the card was a name-brand or not. I've had the issue with several cards.

I constantly have this problem as well, and I've found that mounting the SD card with a reader or in another phone in a Linux environment fixes it for the most part. I think files still get lost, but you get most of what you had back.

I got a 32GB UHS1 card last week and it hasn't had a problem.

Galaxy S7 has corrupted my SD card

I have had my S7 since pretty much the beginning, I was fortunate enough to receive mine fairly early compared to others. Along with purchasing my new phone, I got a Samsung 64GB EVO Class 10 SD card to take advantage of the expandable storage. Everything had been going find until earlier today. I noticed that I got a notification that my SD card was corrupt, I didn't think it was that big of a deal as I didn't have very much data on the card as of yet so I clicked the option to format it. The phone seemed to be having issues reading the actual card as it couldn't seem to format it, an error kept popping up saying that the command had failed. I then put the SD card into my laptop to see if I'd have any more luck with it, and sure enough windows told me that the only way the card could be read was if it was formatted. After formatting the card through my computer, I put it back into my phone. It worked for about 5 minutes or so before telling me it was corrupt again, I'm not exactly sure where to go from here.

I had this Samsung 64GB EVO Class 10 Micro SDXC Memory Card with Adapter (MB-MP64DA/AM) from amazon with my S4 with no problems since it went on sale back in December. Last Friday I got the same message that it was now corrupt and I need to format it. My computer cant see it and I have some intense data recovery software that cant help either. Since those little SD cards have a 10 year warranty I got on the phone to Samsung. I spoke with a Samsung Galaxy expert and they advised me to call their Micro SD support team at 1-800-726-7864. I'll call them tomorrow and report back what they say.

Prolly got a fake from amazon

Amazon do insist they don't sell fake cards, however I have had the exact same problem with the exact same memory card, also bought off amazon. I've used this card in a few different phones with no issue, however upon installing it in my GS7, within a few days I got the same error message as described here. I have contacted Amazon and have had a replacement card (same one) and will see how it goes. I'm on about day three so far with no apparent issues. Tick Tock Tick Tock.....

I'll probably call them up also.. but I think I'll see what happens with yours before I just destroy another SD card

Just got off the phone with Samsung. They're sending me a RMA form to fill out through my email for a replacement. After the whole amazon fake SD card fiasco they're going through they are being very helpful so far. If you can return to amazon it will probably be quicker but I am at day 100 or so with this card.

I think I have the same problem. I have a Samsung card also (not evo) and have used it in several phones without a problem until now. In my case the card corrupts at reboot. I managed to f around and somehow the card was readable again (after re-inserting several times). However on the latest reboot I the phone no longer detects the card at all.
I doubt I have a fake card as I have been using it for over a year now and almost filled the capacity (64GB). I even formatted it when I first inserted into the GS7.
I have since ordered a new card but I hope this phone is not going to be killing cards!

RMA received. Samsung wanted a jpg or pdf of sales receipt and a pic of the back of the card. Card will be mailed to Samsung at my expense ($2 ish) and a new unit will be sent out. Fingers are crossed that the fast charge tech isn't sending card killing voltage spikes through the phone.

Just a quick update guys, in case it helps anyone, but my new card replaced from Amazon is working OK so far without issue.

Update, whilst it hasn't killed my SD card, I've just had an update and after that it refuses to write to any memory card I have. So I'm returning it tomorrow, it will read OK, but not write to.

I'm using a samsung pro+ 64GB card with my S7 and that annoying SD card notification keeps popping out. Sometimes I could see another notification said SD card removed/unmounted unexpectedly then the annoying notification. I've tried using an old 32GB TF card and I've never seen this annoying notification.
My guess is that S7/S7E have some compatibility issue with even Samsung's own newer and faster SD cards.
I'm waiting anxiously for an OTA hoping this is a software issue. I hope my S7 won't corrupt my SD card.

Update: Just received my replacement micro XD from Samsung in less than 2 weeks, very cool. I like their new usb card reader, very slick. Well see how long this lasts. I also just had a OTA update to the S7. Lets see what they fixed.
BlueT

Same issue
Exactly same scenario as bensto23 first described, same SD card, however....I replaced that 64GB Samsung EVO with a Patriot 128GB and after about 2 weeks the same message popped up. But when I put this card in my laptop it couldn't see a problem (the Samsung was unreadable). So the Patriot went back in and everything was good until about a week later....same thing. S7 says the card is corrupted but it's not and works fine after removing and replacing. Haven't had time to call Samsung support but obviously this looks like an ongoing issue. So frustrating since this phone has been so flawless otherwise.

My S7 is in for repair as I type this. It's 6 weeks old. I had a 64GB SD card that I had used in my S5 for 18 months with no issues. I didn't have an S6 due to lack of SD slot and not waterproof. At 3 weeks old, the 64GB card developed a problem. I removed it from my S7, put it in my laptop, only to find it was corrupted, and I couldn't do anything with it. I put it down to being one of those things, and bought a 128GB SD. 3 weeks in again, and exactly the same fault! It is a hardware issue with the S7. I put my 32GB SD card in from my LG Leon, and the S7 wouldn't read that either. Be interesting to see what Samsung will do about replacing cards that have been destroyed by a phone!

Think i might be facing the same problem. When i put in a Sd card my phone freezes up a couple of times a day and without a sd card it running fine. I even think it messed up my first sd card because even after a format i cant write files bigger then 1 gb onto the card without getting a error on the computer. Also i can only do a quick format and if i do a full/long one it will eject the drive and fails every time. Im to scared to try a new sd card and think ill send this one back for warranty.

corrupt sd card
i have same problem with A7(2016) but i use 64GB U3 kodak SD card. it works fine until last week. i saw that i cant play musics so open memory by ES file Explorer and it says that empty. but when connect it to my loptop it had no problem and i find some files that recently created and remove files with 0 byte size. then connect memory to my phone it works nice but some day later the sd corrupts again and i repeat every thing i do last time and it work but sometime later corrupt again. i am confused how i can stop this cycle
help if can please
sorry my english language is not good

Every phone I've had, every forum for that phone, complains of issues with Samsung cards, I would never touch Samsung cards. I've never had an SD card corrupt or fail but then i've never bought a Samsung card.

Got the same problem. Every time I reboot or unmount the external sd-card, the card becomes "corrupted". When I put the card in my PC it's just fine. I can read and write to the card.
I've got the 128gb sd card from Samsung (got it for free with the purchase of the phone).
Getting sick and tired of having manually backup and restore to my SD-card when I reboot my phone. Does anyone has a solution for this?
**EDIT
This must be software related, since when I do not reboot, the SD-card works perfectly fine. It only happens when I reboot or unmount.

had the same problem in my s7, it turned out for me the culprit is when I enable the pics saving to extsd option in camera. this corrupts my extsd.
before extsd it worked perfectly fine for days and weeks and survived plenty of reboots in the S7 (and in my previous phones as well), but as soon as I enabled the pics saving from camera to extsd option in the s7, at next reboot the message about corrupted camera came out. I can replicate this problem with these exact steps, so it is 100% sw issue for me, and related to that option in camera settings... if I use my intsd for camera pics, everything works just fine, I can see and access all my other content in the extsd etc.......

MicroSD card not being recognised.

I have been looking for a solution for days but it seems it's broken. But I shall just ask again, if there is a chance it's not...
So I have a MicroSDHC card by SanDisk consisting of 16GBs worth of storage. Now this MicroSDHC I had used a lot, this SD card worked on other phones, tablets and PCs. It was really convenient. So it was a shock when after nearly 2+ years of having a bricked device, I finally found how to fix it but when I pushed in my MicroSDHC card... nothing registered. It didn't even notice. Not a notification. The screen did not automatically turn on. No noise. Nothing.
Now, what's weird is that when I bought this card it worked with this device 100% fine. Until I bricked it and something probably happened to the SD card reader within those years of sitting around collecting dust.
So let me give you a quick run down of what I have tried:
- Formatting to NTFS, exFAT and FAT32
-Switched it off and put the card in and powered it on again
-Did the same as the 2nd point except just holding it down manually the entire time
Any help would be greatly appreciated.
