A little background... I've been back and forth on the SD card issue with my phone. With stock/7004 it would reboot occasionally and I got worried that it would brick my phone (it already bricked one on me previously) so I decided to rip the card out. I unbranded my phone and installed 7008 and decided to re-install the SD card. It seemed to be rather stable although still would spontaneously reboot occasionally (maybe a few times a week). I installed NoDo with the Hungary trick and it started rebooting much more frequently (several times per day). This time it would even do it when plugged in! Ugh. I had tried the registry hack but it didn't seem to affect anything.
Then yesterday's update came and it hasn't rebooted a single time since. It's a bit early to know for sure but it does seem like the issue is gone.
I don't think it's a coincidence that AT&T is now offering "certified" cards. The cards didn't change nor did their level of testing... Samsung just fixed the underlying problem. Microsoft has shown that even their certified cards can vary greatly; it's just a product of the manufacturing process.
I will note that that I put the registry changes back to their original state (DisablePowerManagement=1) as that is how the firmware that shipped yesterday has it set.
Anyone else care to chime in? Cautiously optimistic that these absurd SD card issues are behind us.
I have not had a single reboot or a stutter on my music. Its been running great!

I went through the same steps too. With the unbranded NoDo update, my phone restarted at least once every 30 minutes. After I applied the ATT NoDo update, I haven't had a single reboot yet. I feel confident in saying that my SanDisk c2 32gb card works now.
Leads me to wonder which other cards will work now.
Running a 16GB Sandisk class 4 card, about 4GB free. Before the official AT&T nodo update, my phone was restarting a couple of times per day. Post update, my phone has been up 1 day 19 hours (so far) without a restart.
File this in the "for what it's worth" department: an acquaintance of mine works on the phone 7 application team at MSFT. He told me that the MSFT LG team had made a bunch of fixes to the SD driver, but the Samsung team was on a different release schedule and was not able to pick up the fixes for the original Focus release, but rather they were picked up in the nodo release. Given my results and the results I am reading about, this makes sense.
Comparing my WP BENCH storage speed before and after the samsung update, it increased by over a MB/s. I also have not noticed any stuttering or anything like that.
The next test would be to benchmark a non-certified card against the 8gb AT&T certified card to see if there are any noticeable speed differences...
That would be GREAT info.
I can confirm that the Transcend 16gb class 6 card still does not work after nodo. It will not even boot up after formatting the card and starting the phone.
Will you guys reply with what card you have IF the Nodo update IMPROVED your card (model, class, size and everything)
I was having problems with my Kingston 16GB C4 card, and ended up having to do a hard reset without the chip to get the NoDo update. After reading a few comments here, I added the old card and did a new hard reset. Now I have the full 22GB, but the phone wasn't remembered by Zune like it was last time. On the plus side, it looks like NoDo and the firmware are now baked in so no worries about loosing these when resetting the phone.
Anyway I'll reload all my stuff which could take weeks and I'll let you know what happens.
[The Kingston 16GB C4 card was one of the more stable cards out there. I believe only the SanDisk 8GB, SanDisk 16GB and Samsung 16GB cards worked better. I have not lost any data with the Kingston card before NoDo, but it would be slow enough to prevent me from opening some programs ocationally. I would also get a random reboot every few days.]

16 GB Samsung from Nikolai on eBay. I think it's a Class 2, but I don't remember.
I have the microcenter 16GB Class 2 card loaded to 3GB free. Never had problems before Nodo, still no problem now after Nodo.
Same with mine...no issues or slowdowns or glitches of any kind. Still using the same 16GB class 4 card, too.
I purchased the new, Windows Phone approved Microsd card at AT&T before the NoDo update arrived. It installed fine, worked great before and after the update. It's an 8 GB Sandisk, Class 4 card. Everything is working great.
I jsut posted this on another thread, but it fits here too.
I just tested my Sandisk 32gb class 2 card and it screwed everything up. I had to re-establish my phone with the Zune software, then i had to sign into my phone again. Now i can't add email accounts to my phone. Tried to revert back to my backup, and now it is not showing. I'm assuming because i had to re-establish my phone with the Zune software. If i revert i will lose homebrew and Unlock, right? Does anybody know how to bring back the backup again in zune? What are my options? Problem occured over the 10gb mark.
When i got my focus , i removed the sandisk 8 gig card from my Fuze and put it in my focus and have not had a single problem from the git go. and i originally ordered it from the cell phone shop . com. lol guess i was just one of the lucky few.
Kingston 32GB Class 4
My Kingston 32GB Class 4 SDHC has worked well from day one with the exception that only half of the capacity can be used.
Once the Device holds around 20 GB of data the phone reboots when trying to add more.
As we approached the Nodo update, I had hopes that this barrier would go away, but alas after Nodo, I still cannot use the full capacity of the card. It exhibits the same behavior after filling to around 20 GB of data.
Has anyone had success with a 32 GB card that allows access to the full 40 GB available? If so, which card?

If you believe that it looks like we can add an additional 32 Gig SD card to the Samsung focus prior to initializing it (or at least requiring a hard reset after it is inserted), exactly what is the type of card which we may utilize? Brand and type, or even better, a link to an example would be an ideal answer. TIA.
If this thing really does need to be in the phone before it is set up, or require a hard reset, I may as well have the thing (SD card) in my hot little hand before I walk into an att store and the clerk tries to slip the battery in the phone.
Is a standard Micro SD all that is required?
http://wmpoweruser.com/expandable-storage-confirmed-in-windows-phone-7-required-a-hard-reset/
According to Microsoft it requires a special high-performance sd card so I doubt a normal one will work. If it does work you probably won't like the performance. http://www.microsoft.com/windowsphone/en-us/howto/wp7/basics/sd-cards-and-my-phone.aspx
i read that they will be availalbe at att store where you purchase your phone.. may cost more than other places but without knowing what type may have to wait til phone is released..
Hmmm...I cannot find a US vendor to purchase one of these:

Expected release date November 8, Carrier AT&T according to Phonearena.
From what I have read, the special part of this is the way the OS creates a RAID to combine internal and external memory. I suspect that a class 6 card will work perfectly.

With it being extra important that the Micro SDHC card doesn't fail; which brands of flash do you people recommend?
I have had a 8GB class 6 Transcend card in my LG Xenon for almost 2 years. Used it in my GPS, and my daughters DSi, and have added countless movies to it. It's been heavily used and hasn't failed. But when I go to buy 16GB the reviews aren't so high on the Transcend.
* I can't find a reference on PhoneArena to the above mentioned Samsung 30nm-class, High-density NAND Flash for Mobile Devices. Were you referring to the phone it's self being released on Nov 8th?
Has anyone any word of the type of SD card we will need to get?
On the AT&T wireless message board there's a posting of an email from Jeff Bradley, AT&T Senior VP of devices, that states it will support a class 2 or higher microSD card.

AHHHH....
"Windows Phone uses a special high–performance SD card that works differently than SD cards in other devices.
When your phone is built and first set up, its internal storage and SD card are combined and recognized as one storage system," -Microsoft
I believe this is referring to the 1GB ROM internal storage(for operating system) and 8GB internalSD card flash both being the Samsung 30nm NANDHP Flash
I've read posts around the net about a Samsung rep stating the MicroSD just under the battery cover would be removable. I'm starting to see that as a possibility.
I just received an email back from Samsung Tech Support.
My Question: " SGH-i917 Focus for AT&T, need clarification on MicroSD slot
Are MicroSD flash drives used in the slot under the battery cover capable of being removed with out hard resetting the phone/operating system (Windows Phone 7)?
I'm not referring to the internal 8GB memory in the core of the phone. "
Their Answer: " Thank you for your inquiry. If you are referring to the memory card that you have on the phone, it will not affect the functionality of the phone either the operating system of the phone.

***EDIT***UPDATE***
OK, just got off phone with Samsung tech support, via the phone # above.
She told me that the MicroSD card slot under the battery cover WILL BE REMOVABLE WITHOUT HARD RESET of the phone.
That I can use multiple MicroSD cards with the phone, i.e. adding movies to multiple MicroSD flash drives for a vacation.
AS LONG AS the flash drive is only used in the SGH-i917 Focus and a Computer.
If added to another phone or device it may require reformatting before using in the Focus again.

That is just so contrary to anything and everything we've seen so far that it is hard to credit.
I've already ordered a class 6 16GB card (the Transcend, I hope it fares better than the reviews cited above) but I ordered it for the additional storage, not with any expectation of being able to swap it in and out or use on a computer.
As far as hoping for anything more, it would only be that a class 6 card might perform better than a class 0 or 2 which others in the HD7 forum report are being shipped in the HD7.
Well I doubt the tier one tech support agent knows more then the hands on reviewers online. Based on the comparisons, I think the Focus uses at least class 4 or 6 speed internal memory. Every video and head to head comparison Ive see thinks the Focus is faster the its comp. I did notice updated spec stating 512MB RAM, 1GB Flash Rom (Prior was 1GB ROM), 8GB Flash Storage. I think the Flash ROM is Samsung's Nano Flash chips, the 8GB storage Ive read to be ScanDisk. Does ScanDisk use Samsung flash chips?
A week from today the answers and im sure more questions will start flooding in.
I got the Focus this morning, and I tried a run-of-the-mill class 2 SanDisk 16GB card, and after doing a hard reset, its working like a charm. 22GB of memory for me. Doesn't appear to have degraded my performance, either.
Where do you lookup the available memory? I've inserted a class 4 16GB Lexar card but I don't know where to look to verify the memory.
memory card
what's being told to all att employees is that we are not to sell any memory cards with the phone because they're not supposed to work with any of the ones we carry. I've been afraid to put one in mine because of this but if its been working for ya'll idk what to believe now.
Rep at the att store told me this morning that theyre working on an OTA software update to correct this SD card issue, so hopefully it'll be sometime soon.
Has anyone tried using the 16Gb Kingston Class 6 card in the Focus? Results?
My 16GB class 6 card is working great. 22GB of storage.
Go to settings, about and it will tell you have much storage. I had to hit reset phone under that page for it to work.
I installed a 16GB class 6 card in mine this morning and it was working fine, then after reading of a problem after a soft reset I tried it and sure enough, it forgot everything I'd set up and I had to start over.
I have been using a pny 8 gb class 4 card in my phone for the past 3 weeks. It had been working great, but today it reset and lost all my data. God the phone up and running after a hard reset.
anyways, I want to purchase a 16gb card now. But i want to get one that I know will work. I read through the working sd card thread, but I found it challenging to pick out the ones that really worked. many people had success stories, but often they were from cards they only had for a few weeks, or with little of the memory used.
so my question, is what is the safest 16gb card for the focus. One that no one has had any trouble with. After reading through the thread i saw no one complaining about the samsung 16gb class 4. Can any confirm or deny this?
I've been running the Samsung 16g for about a month now without a single problem. Bought it off eBay from seller doctorwatsonsclinic.

I have had it about 3 weeks and I only have about 10 gigs free on my phone. I will try to fill it up all the way and let you know how it does.
anyone else?
Going by the posts, the safest would be these Class 4, 16GB cards: Patriot & Kingston.
I've been using a 16gb Samsung class 2 for the past 2 weeks. No resets or lost data. I've noticed some slowdown at times but nothing major. Much better than the 32gb SanDisk class 2 I was using, which had multiple resets and data loss after just five days

Goodnight/Good morning my fellow XDA-ers!
Okay so I have a USA T-Mobile HD2 I installed WP7 the day after it was released by DFT but the day after I was forced back to WM6.5 due to the SD card issue, my device was constantly restarting every 15-ish minutes. I was wondering if anyone has any experience running WP7 successfully on their HD2's for a decent amount of time with a specific card. I'm willing to purchase one of these cards as I want to get away from WM6 as soon as possible, but I really want to know if the card will work!
What I'm looking for is a 16Gb card that works. So if you have purchased a 16GB micro SD card that has been working flawlessly with your HD2 for some time now, please chime in, and please include a serial number as I want to get the exact thing!
Thanks for your time.

Just recently purchased a Sandisk 16gb card. Works flawlessly. No crashes, hangs, resets or whatsoever.
AAARRRGGHHH!!!!
how many times do a few others and myself have to tell people this!!!
no two cards are alike, you could buy two identical cards and one might not work, there is no "working card list"
Statistically you will have better luck with a class 2 or a class 4, ive personally had better luck with sandisk class 4
but that is it, its just luck
I've been running mine flawlessly since the first rom (now on my second) on my HD2. I'm using the stock 16gb SanDisk that came with the phone. Indeed it is "luck of the draw" but most people I've talked with and/or flashed for others have had no problems with the stock sd cards.

Yeah, the class 2 sandisk with serial ending in A11M were called wp7 certified by sandisk for about a day before they pulled that certification. What dazza said is true... at the moment, card makers don't test their random access speeds and don't keep them consistent enough batch to batch to guarantee any specific card will work. Sandisk makes very high quality cards and I think you're best chance of getting a card that works is to go with class 2 or 4 sandisk. I have few Sandisk class 2 cards ending in A11M... 1 8gb, 2 16gb, and 1 32gb. All work... All work flawlessly except for 1 of the 16gb cards, which give a little lag, but no resets or anything like that. After testing, the access speeds are very different on the 2 cards, even though they are the same brand,class, and model number. Were even bought from same store, but 6-9 months apart.
So yeah, if you want to try wp7, go for a class 2 or 4 sandisk. It will most likely work... but there's no 100% guarantee. But sandisk has good warrantee... if in the rare case it doesn't work, tell sandisk it's brok or something and try to get them to send a different one.

No this is only 8gb so far. Hopefully when they make it official they'll have 16gb and 32gb versions too.

Yeah thats what I was going to say. I just picked up a 16gig for $25 at Fry's this weekend. Not for a WP7 though mind you.
If I had to justify that $32, then I'd say that Microsoft and AT&T worked with Sandisk on selecting the manufactured cards that met the minimum performance requirements; all other manufactured cards get the regular consumer packaging.
Personally, I'm running a Sandisk class 2 8GB card (vs the Sandisk class 4 8GB card) and I haven't run into any detrimental issues yet. Performance is choppy/laggy once in a while though...

Hey, I bought my ATT approved Windows Phone microsd card April 15, 2011 and I'm glad I did. I know it was a little high, but it works and it is reliable. It has not caused any problems. Given past memory card problems, I am not complaining. I didn't mind paying extra for consistant performance and reliabality. By the way, the packaging of this card does have the Windows Phone and round WP7 logo located on the top right hand corner of the packaging and the AT&T logo on the lower right hand corner of the packaging. As of today, 5-25-2011 still no issues and working perfectly.
I note under the AT&T site for accessories for the focus it lists a Class 2 Sandisk Micro SDHC card for 79.99

I called ATT support because I wanted to find out something about the focus. Fake tech issue you can call it
But during the conversation he said microsoft has not certified any cards as of yet. He said they sell cards that work but none yet is officially certified by microsoft. Idk if thats true but I have not seen a sd card with windows logo yet. He also was explaining how the focus was the only phone to have a sd slot.

I dont know when if ever MS will put their stamp on a card, but trust me the sandisk cards work.
Yeah I am running the 16GB Class 2 sandisk from the AT&T store and have had zero problems yet and its been 5 days.
Editting to add that it is NOT labeled windows phone 7, it is just a repacked standard Sandisk Class 2 card.
So an AT&T rep told me that if you bought the AT&T WP7 approved SD card that you could pull it out, put it in any PC an read the info on it without issue just like any other SD card.
????
Thats a load of crap Tiggah. The card is formatted using the Secure Digital technology. Locking it to the phone and ONLY that phone.
Can you put it in another phone and see data? No. Can you format it? Yes.
Can I put it in my computer and see data? No. (I tried this FYI and nothing)
Can I see data via the sync cable and the two reg hacks? yes.
So just wanted to update this with a few things. After more than a week with teh 16GB Class 2 Sandisk SD card my phone has worked perfectly.
Yesterday I needed to take some data home from work and used the reg hacks to see the Phone in explorer and transfer enough data to leave it about 600MB free.
When I got home I did the same reg hacks and started having trouble copying the data off. On one file the phone would just reboot.
No matter what I did it would reboot and come up and tell me my SD card was corrupt and to format it.
I would just pull the battery and reboot and it was ok again. I was never able to get that one file but was able to get the rest.
So a word of warning... if you want more memory to do what I did, don't complain if you start having problems.
Your taking an unsupported SD card and using it in an unsupported fashion via explorer. Don't cry about it later.
Ever since I bought my Focus in November, I couldn't get it to go for more than 24 hours without randomly rebooting. Sometimes it would reboot as much as several times per hour.
After applying the April 19th update, my Focus has not frozen or randomly reset in the last 48hours. I am using the same exact SD card that I had in there before the update, which did not work.
Are others finding the same thing? If so, this is really good news!

All of that sounds very promising. I will get my hands on another sandisk class 4 32gb card during next week and test it again (this time hoepfully without destroying it).
48 Hours and SD card is still working!
I have a 32GB Sandisk Class 2 card that I tried in my Focus prior to the NoDo update. The phone was somewhat sluggish (scrolling web pages, app lists, etc would lag and stutter) and would reboot itself every couple of days. It appeared that it returned to factory settings after the reboot but all of my data would return after power cycling the phone. The reboots didn't start until two days after installing the card.
I decided to try the card again after installing NoDo and reading this thread. I reinstalled all of my apps and filled up the phone with over 15GB of music, videos and pictures. I noticed immediately that the phone remained responsive. It has been 48 hours and I have seen no sluggishness and have had no reboots. I am crossing my fingers that this will continue. If they really did fix the SD card issue with the NoDo update why aren't they making a big deal out of it?
Using a Sandisk 16GB class 4 pre and post update. Mine is more stable and very pleasing now. I don't see the slow main screen loading I did pre update.
Sandisk 16gb card. Rebooted constantly pre-Samsung update. Don't think it's rebooted a single time yet. I'm a happy man.

Good question, until MS or Samsung actually come out and say they fixed the SD Card situation or come and say they did "something" concerning this issue I'm holding off..
You would think if they addressed this problem someone would say something!!! Lord knows if they did sales for the Focus would jump, the ability to add up to 32Gbs is a pretty big deal..
I am getting inconsistent results for the storage card write rate using WP Bench. I ran it multiple times, back to back with the following results: 5.6, 4.9, 4.9 3.2, reboot phone, 3.6, 3.2, 3.1 . The rest of the benchmarks remained very consistent. The phone warms up quite a bit after running the benchmark. Perhaps the performance is affected by internal heat? It probably is just unstable performance with this SD card, even though the phone has been very stable and responsive after the NoDo update.
SanDisk 16GB Class 2
I installed a SanDisk 16GB Class 2 when I purchased the Focus in late December last year. Some random reboots, maybe 3-4 in all that time, no lost data. Since I updated to the official ATT Samsung Update, not problems at all. Still too early to tell of course, but looking good.
SanDisk 32G class4
before nodo: Works but reboot ~ 2 days a time (sometimes don't find the card after reboot, and need another reboot)
hacked installed nodo: Works but seems to reboot less, about 4 days - 1 week a time (Still sometimes don't find the card after reboot, and need another reboot)
Samsung official nodo: works and don't notice the SD related reboot yet, but too early to says.
After NoDo i bought a Sandisk 32gb class 4 and no issues since 3 weeks. No reboot, data remains after soft reset. Have almost 23gb of data.

I had nearly the same issues, except mine would reboot even more often than that. I have gone for 5 days now without a single reboot. I am glad to hear that so many other people are having similar success!

I would highly recommend the less-expensive one sold and fulfilled by Amazon. Amazon is an authorized seller and highly reputable. You aren't likely to get a fake from them. The other sellers at Amazon...I can't vouch for.
Question
Are the 32 CLASS 4's fakes or are they real. (sandisk)
I cannot find the 32 class 4's on the sandisk website.
I purchased one of the newly released Windows Phone approved Microsd cards from AT&T on Friday before I received the two AT&T updates the following week. The card is an 8GB Sandisk Class 4 card. The installed fine and works fine to date. No problems or issues that I have seen so far. I am very pleased with the card and the updates. I am using a Samsung Focus which I purchased in January. I currently show 14.59 GB Total Storage and 13.10 GB Available Storage.

i get it in ebay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemVersion&item=280652928461&view=all&tid=652993750018
the card doesn't have blister, but trust me, is genuine. The card arrives in 3 weeks to my country (Mexico) and comes from korea a think. I search the inferior code in google and found is a real item code in sandisk website.
My experience with Sandisk Class 2 32gb. I do have homebrew apps installed.
i just tested my sd card and it screwed everything up. I had to re-establish my phone with the Zune software, then i had to sign into my phone again. Now i can't add email accounts to my phone. Tried to revert back to my backup, and now it is not showing. I'm assuming because i had to re-establish my phone with the Zune software. If i revert i will lose homebrew and Unlock, right? Does anybody know how to bring back the backup again in zune? What are my options?
