Hi all,
Currently, the Focus/WP7 in general is having some technical difficulties with external SD cards. Below is the list that users have confirmed compatible and incompatible. I will keep this updated until the issue is resolved, in hopes that new users find this list and make the correct purchases. Please post your results with brand name / storage capacity / class #. Also, please only post your results after installing the card using the prescribed methods from the Samsung Focus instructions or the Windows Phone 7 site. This includes formatting the card and then testing the stability with soft reset(s).
*Note* Some people are reporting that their cards will work for about a day, then proceed to make the phone go berserk, restart, and then return with the data cleared and only 15MB of available storage. If this happens to you after initially reporting a compatible card, please check back in with us! Use this list with caution, as the results are based on our short time with the device. Thanks

I just got the regular 8 GB Sandisk MicroSD in the AT&T store and it works just fine. I used the reset option from within the phone's settings, not by holding down the phone's buttons.
So far, no issues. Memory was detected and allocated properly and my music has been synced and everything.
So far I can gather the cards that are not correctly working, as in you can get them to recognize and sync initially but once you power down the phone and bring it back up everything is gone and the phone only reads "15mb" of storage space. Only way to get it working correctly again is a full hard reset / format.
Transcend - Works but has the listed issue above (I have a 8gb class 6, back to amazon it goes)
A-Data - Works but has the listed issue above
Kingston - Works but has the listed issue above
SanDisk - Works 100% reboots and all no issues (friend has a 32gb class 2, no issues at all!)
Hope that helps
Using a SanDisk 16 GB class 6 (whatever that's worth) that I bought back in May or June this year. Popped it in and ran the format utility via hard reset (vol down + camera + power) which formatted the device.
Have 22 GB or so of total space with about 12 GB in use via mostly music, with a few apps and games, and a handful of my favorite photos. The phone appears to be running just fine. I've soft reset twice ('goodbye' via power button) and haven't had any data loss / configuration issues at all.

So you have performed a soft reset and your data remained intact? Also, if possible, can you post what Class (2-10) you are using? As stated by MS, the class isn't so much of the issue as other factors, but just for reference's sake. Thanks!

For the brands that you listed as working, but with the issue listed above, I'm hesitant to post those as not working as it may only be for certain sizes or speeds with that given brand, and I don't want to cause panic for anyone who may have purchased that particular brand but has a working configuration. I will post the 32gb class 2 sandisk model and 8gb class 6 transcend, but if you can provide any specific configurations (size/class) for the brands you listed, that would be helpful. Thanks for your input
AT&T rep had me walk through the setup at the store when I bought it. I didn't have the microsd card with me so I installed it when I got home (Kingston 16 GB Class 4). After powering on the phone it didn't see the card. I completed a reset and after that it worked. I thought it has been said the cards wont be seen if it was inserted after the first setup because of the way it sets up the storage as one virtual disk from the first setup......

The reason I thought it might be useful to put this list together is many people are reported that despite meeting those requirements, there are certain cards that simply don't work. According to Microsoft's own website, simple matching the class requirement won't necessarily mean your card works, as there are other factors not listed that factor in to it. If it gets cleared up in the next few days with an OTA patch, then this thread will be moot but for all the early adopters who are trying to get an SD card in this phone before that, this list might prove useful
Oh I understand and agree. I more or less thought it was interesting that Samsung said that a class 2 would work.
Also this was posted in another thread. Too bad there are currently 3 or 4 threads on this issue. Microsoft has a KB on this now:
http://support.microsoft.com/kb/2450831
Still waiting on UPS to deliver my Class 6 Transcend 16GB card today. Will test and post here in a few hours.
The card in question will be:
www.amazon.com/gp/product/B0026L7DGA/ref=oss_product
ADDED: Product sheet/specs about the card is at:
www.transcendusa.com/support/dlcenter/datasheet/TS16GUSDHC6.pdf
Color me clueless yet maybe the built-in Error Correcting Code (ECC) to detect and correct transfer errors is key??? i felt everything has error correction nowadays, though i could be incorrect.
---------------------
---> ADDED DOES NOT WORK
---> First recognizes it all, then after reboot only recognizes only the first 8 GB
-----------------------
I put a 16GB Class 2 in lastnight, everything worked fine, lots of stuff sync'd to it.. then this morning after some music playing, the phone started crashing and rebooting itself.. then I lost all my settings and memory and had to do a complete format again without the SD card in place.. so far running without the SD card. its doing fine.
I'm thinking maybe class 2 is not fast enough and class 6 or 10 would be better.. I think I'll go get a class 10 later today try that out

I did a reset via the phone's settings (Settings -> about -> reset your phone) and everything that was on the phone was gone when it booted up again. However, since I did that, my data has remained intact on the phone and I've had no issues since.
The card I have is a Class 2 Sandisk 8 GB micro SD card.

What brand was the card you were using? Also, did you follow the instructions for inserting a sim card as per the Focus manual? Thanks

SanDisk, and yep.. I followed the instructions, Format, etc etc. 20GB or so was available.. and everything was normal for 12 hours or so.. then.. BAM.. it started crashing,, and then all settings lost.. and space of course.. it was like it just became corrupted.
I wonder if the mircro sd was loose or something. or dirty contacts. dunno.. I may try it again tonight. or just buy a faster class card

Sounds good, let us know the results if you try the SanDisk again, as most people have posted that they had good results with them.
Not working:
A-data 16GB class 6
A-data 4GB class 6
EDIT: let me rephrase "not working". The phone will recognize it and work fine until your soft reset. Then all settings, etc are gone.
I just tried my Kingston 4GB class 4 and it worked.
WORKING : Kingston 32GB class 4
I first tried volume down, camera and power button. That gave me the download mode window and it lasted for about 20min before I gave up and took out the battery. then the phone came on fine without the new memory. I then went to settings>>about>>reset and that worked perfect. I have re-setup my phone with apps and exchange.. then I powered off (goodbye) and then on twice.. all my data is still there and it says I have 34.17 gb of free space ..using 2.36gb
but 2.36 + 34.17 = 36.53
where are my other 3.47 gb? I suppose they are the OS
but the world is great.. a windows 7 focus with 32gb card.. AWESOME!

Hi All,
Does anyone else here suffer from continual SD card corruption? It appears that the early superblocks of my card are continually being corrupted by my Hero no matter how I format or partition the card.
Naturally I would assume that this was a card issue but running some load tests on a laptop shows the card to be functioning properly and reliably. Next thought would be that it's the phone but using an alternative card in the phone seems to be trouble free also. Any ideas?
My alternative card is a 2GB vs the troublesome 8GB card that I would prefer to have for music, etc.
I see lots of web results for people complaining about corrupt SD cards but no solutions or responses.
I had this problem too. Fixed by buying a decent class 6 microSD card. No problems since.
Okay... I know there are cheaper deals in the USA but for the cost and return policy I will buy this locally. This unit is going on sale starting May 6.

Question is though, is the Sandisk 16GB Micro SD Class 2 card a working card for this phone ? There are so many postings but hard to pin point if this is a good working card with no reboots or data loss.
Appreciate quick responses as I want to pick this up before they sell out.
Thanks !
generally after the samsung focus nodo update the phone is not showing the symtoms of earlier sd card problems. Sandisk should be fine, class 2 or 4 seems to be the best class right now for this phone; even though microsoft orignally said class 4 or higher. You should check out the sd card thread sticky
Card has been purchased... I've done 3 finger salute and connected to laptop. Seems there was an update from Microsoft, so let that run and update.
Now syncing the card to all my wonderful music. I've loaded 4GB so far. Another 12GB to go. Will report sometime tomorrow if any reboots or data loss occurs.
Oh my... I guess I had more music and pictures than I thought ! Anyway the total storage is 22GB and available memory is sitting at 1016MB. Essentially I have maxed out the storage. So far no lag, no blips, no reboots, and no data loss. It's only been about 90 minutes though ! Will leave it over night and then use it more. Play music, read emails, make phone calls and then see what happens.
Any othe suggestions for testing this out?
Seems to be working perfectly. If anyone has suggestions to testing the load and trying to get the card to foul up please make suggestions. Future Shop has a good return policy but it needs to be returned with in 14 days of purchase. So far though the card works !
Can you check the speed (using WP Bench)? If it's good, I think I'll buy one of these.
So, bought the card - only the one that showed up was a class 4 16gb San Disk (as opposed to class 2 as listed in the order). So far has been performing fine, although I have had the occasional slowdown / lock-up (which may be a function of the phone trying to find music on the card). WP Bench score for storage access has ranged between 2.8 and 5.6...

Class 4 for me too!
I Have HD7 Runing On HD2. My Memory Card Dont work. I Look around the forum and still dont Understand what type of memory card work or maybe there a trick to it.
http://www.google.com/products/cata...=X&ei=x0xXTpL3J4HLsQLql-m5DA&ved=0CGYQ8gIwAA#
Thats The Kind Of my memory card.
Brand: PNY
Size: 8Gig
Class: 4
Any help will be appreciated
theres no way of knowing if it works until you try it.
stick to class 2 or 4 cards, sandisk seems to have more luck than others but ultimately its luck, there is no list of working cards, and just because someone has a card that does or doesnt work doesnt mean you will have the same result
it is thought that it needs higher 4k random access speeds but we can be sure as everyone seems to have different results
And when flashing my phone..should memory card be in or out.

Just killed second SD card in my S7 Edge and by 90% its caused by GPM while downloading my archive to phone. After fresh install I cached maps to sygic navigation, one more other app and saved around 4GB of data without any problems. Then I let GPM cache my playlist worth cca 5GB of music. After hour or so checked phone and found card disconnected. And it was dead, didnt work in phone nor pc anymore. So I exchanged it for another one (RMA) and did exactly the same with another. Unfortunatelly same situation, other apps downloaded data correctly, GPM killed card after hour or so of downloading.
Both cards were Kingston 64GB U3 fast cards.
Not sure if I want to try third time in row...
I've had bad experiences with kingston microsd cards - randomly failing or getting a lot of errors. I initially thought it was bad luck.. now I use Samsung and Sandisk ones and I haven't had any problems.
There must be a quality issue with the kingston ones. Have you tried a different brand? I'll try an old samsung card and see if it messes up with Google Music
I typically stick to SanDisk and have about 10GB of music from GPM on my SD card at any given time. Never had any issues through various ROM installs and wipes.
Will take card to RMA (again) and get different brand, probably SanDisk. Hope it will be better luck, because not sure how many cards I can succesfully RMA befor they get some suspicion in shop

Are you enabling encryption on the SD card?
I had that setup on my Lexar 1000x to begin with and after a few days ended up with a corrupted filesystem in my GS7E.
I reformatted the card using Windblows, reinstalled it and reformatted it with the GS7E, but with encryption disabled, and performance has been more consistent (read and write).
I'm just wondering if SD card encryption could be mis-behaved.

I personally have used both 128gb and 256gb cards on my note 3 both seem to work however i am getting a odd issue on my 256 gb when i download a file over 5mb to be saved on the card the phone reboots. Not sure if it is an issue with the phone being able to address the space above a certain point. update it turns out it was in fat 32 im emptying it and going to format to exfat
