I think I should post it here to, so here's the pm:

"Hi there,

My story is as follows:

I had a Sandisk Class 4 32GB that I tested prior the Nodo update. Actually I got a lot of reboots, some with data loss, etc. Finally the card stopped working and was tested to death.

After applying the Nodo, and the Samsung update I installed another one and since a week e.th. works flawless.

Keep in mind that, if you install such a card, you will have to hard reset and won't be able to do such a thing as a backup restore. So you will loose the Chevron unlock if installed, except you restore a preNodo update, install the sd card, unlock and update. That'll work with Chevron.

Sandisk Class 2 and Class 4 seem to be the safest bet. In fact I think Class 2 cards have pretty similar specs to the Class 4 ones, and were underated a long time.

There's no such thing as a model number on the card, just the serial number, and that won't help you.

I hope I could help.

Bye!"

Yeah, and keep in mind, I didn't fully load the card till now, and of course its only been a week. To be really sure we have to wait a few weeks more.

Additional I would recommend to install the most apps first, and then load up the card with all your music and video files. Just to be sure these programs are installed on the NAND and not on the microSD. Should lead to faster loading times. But that's just a guess of mine.

My Focus is now up again after installing the Samsung 16GB class2 microSDHC from JT (Nikolai)electronics Ebay store. Ran WP Bench and got 6.53 MB/s storage. Wonder why is wasn't 4.9 like everyone else who runs this card ?
[Focus General] MKohlman:
I've been trying to post to this group with regular updates and now seemed like a good time to do so again.

I've had a Sandisk Class 2 32GB (purchased from the ATT Store and on launch day supposedly was compatable) installed in my Focus since November and since the NoDo and 3.1.0.7 firmware update I have had zero issues. Prior to that I was one of the lucky ones who never had a data loss issue but I did have numerous problems with random reboots and freezes when playing back Media so as always your mileage may vary...

Mind you it took both as while stability did improve with just NoDo, I did not really get to "no problems so far" until the both NoDo and the updated firmware was installed.

Currently I have 21GB on the phone consisting of all types of media (Audio, Video, Applications, etc...) so the card is in use.
[Focus General] PaullikesWINMO:
That is great news. There are Sandisk 16 GB Class 2 on sale (in Canada) so I'll give that a try. If they have the 32GB I'll try to negotiate something close to a sale price comparable to the 16GB.

Edit: I now have the SanDisk 16GB MicroSD card and have it installed. I'm currently maxing it out syncing my music (16GB+). In case anyone is in Canada reading this and you are looking for a decent deal, here is the link...

[Focus General] TIGGAH:
I installed my new 32gb chip today. I put about 20gb of data on it and so far so good. I'm pretty sure there is nothing to worry about after the SD fix was pushed anyways. Still it's nice to have a reliable 36gb of space to play with.
[Focus General] seijuro:
Nice

Thanks to this thread and posts, I successfully installed a Sandisk 32gb Class 4 card on my focus (after updating to NoDo of course). Its been only one day, but zero problems so far!
[Focus General] OklaPony:
I bought one of the Samsung 16gC2 cards from Icemonkey and installed it last night. So far so good but if it fails I'll post up.
[Focus General] kms108:
can someone help me out on this, i want to buy this, but cannot send him a message, can someone send him a msg and ask him the cost of shipping to hong kong.

Any performance issues or slowness with going with Class 2 instead of Class 4??
[Focus General] PaullikesWINMO:
I have not noticed any performace difference with the class 2 card I have installed.
[Focus General] MKohlman:
Performance

I've not noticed any and running Winbench yeilds a storage result of around 5.6 MB/s on a nearly fully loaded card (currently using 29GB of 36GB available)

On the other hand, I've noticed that for Sandisk Cards at least there does not appear to be a lot of difference in performance on their Class 2 vs Class 4 cards...
[Focus General] OklaPony:
I just now got enough stuff loaded so that the available storage shows under 16 gig. So far so good, no hiccups of any kind.
[Focus General] BenJG:
I've had a 16gC4 SanDisk running in my Focus for about a week now. I got a couple of slowdowns and freezes (but no data loss) in the first few days, but no problems for a while now. Strangely, however, WPBench won't give me a storage result anymore (gets stuck once it hits the storage memory). Anyone know why this would be (the card has about 11g on it).
[Focus General] Sebo1985:
Two weeks later, the card still does run without a single issue.
[Focus General] jfreiman:
32GB Sandisk Working GREAT!

I had a 16GB Kingston card which failed before the Nodo and subsequent updates.

I just got a SanDisk 32GB C4 card from a local retailer and it is working flawlessly.

I filled it with 320+ CDs worth of music as well as about 10 or so apps/games.

I have restarted it several times, pulled the battery out several times and no loss of files.

Also, there has been no lag seen and everything is working wonderfully.

This has been the greatest purchase ever! :)

I attached the packaging and image of the card in case anyone wants to see if they can order the same one. (I got mine from centralcomputers.com)

SD Problem Fixed with Samsung Firmware Update

I posted back on this thread in November 2010 about the instability of my Sandisk 32GB Class 2 card. I tried all the suggested registry hacks and saw some improvement in stability, however, the phone would reboot randomly. This continued even after I applied to NoDo update. Nevertheless, a few weeks later (or about 3 weeks ago) I applied the Samsung firmware update on my Samsung Focus. The phone has not rebooted since. I have used 16GB so the card is being used. At least for me, the Samsung firmware update fixed the SD problem.
[Focus General] All5horizons:
Picking up my Focus from ATT today. Stupid question but should I add the SD card before the initial set-up and connecting to Zune or after? I know I'll have to do a hard reset if I do it after. Just wasn't sure if it makes a difference.
[Focus General] eondei:
Where did you get this Samsung firmware update?
[Focus General] msg95:
I have focus rev 1.3 and Nodo. Purchased Genuine Patriot 16GB class 4 card, reset and started sync (mostly music) with zune software. Sync was fine until I surpassed 7.5-8GB and then received timeout error (device not responding). I discovered if I synced 4 to 5 songs (50-60MB) at a time I would not receive time out error. Took a while to finish sync. Phone was hanging and having probs until soft reset. I have 13.3GB used out of 22.09GB available. I noticed probs (freezing) in marketplace and occasionally when playing games. Had card in phone for 2 weeks and zune software shows the phone having only 1.65GB of music, 20-something GB photos, and 16+ GB of reserved space, so something is not right. Other operations on phone appear to work as well as pre-card installation. However, I did notice some lag when changing settings, etc. If I download/install new apps, I have to soft reset phone or I have problems. When people post success with certain cards, I'm curious if they have been in marketplace, played games, etc. without these problems.

Card: "NEW 16Gb Genuine Patriot Memory Card for SAMSUNG FOCUS SGH-I916 Cell Phone" from Amazon

Patriot Signature 16GB works

Patriot Signature 16GB Micro SDHC Class 4 Flash Card Model PSF16GMCSDHC43P, works. No issues.
[Focus General] OklaPony:
Well, not knowing what state of update your Focus will be... I'd take it home, hook it up, make sure it updates, then install the card and hard reset.
[Focus General] jfreiman:
That sucks, I wasted $$ on a 16GB C4 card from Kingston which didn't work properly before or after the NoDo update. :/

Wish the memory companies advertised the read and write speeds etc....
[Focus General] vedichymn:
These were released in the US along with the official NoDo update.
[Focus General] gahbmwm5:
Hmm,

I may be incorrect, but as I review this from Windows Phone Blog:

"Apr1520

11by Eric Hautala111 I’m happy to report that two Windows Phones sold by AT&T are a big step closer to getting updates.

The LG Quantum and Samsung Focus are now scheduling both the February update and the March “copy and paste” update. We’ve refreshed Where’s my phone update? to reflect the status changes to these models. We’re now working hard to expedite the delivery of these updates to you.

Eric Hautala

GM, Customer Experience Engineering

P.S. I forgot to mention the update we’ll be shipping to AT&T customers also includes support for two special AT&T features. The first is “WISPr” protocol support, which makes it possible for your phone’s data connection to automatically switch over to AT&T Wi-Fi hotspots when in range. The update also includes support for AT&T Address Book."

I have a branded AT&T US Focus v1.3, no forced Walsie NoDo updates, nor other mods, and I am somewhat confused too, by this Samsung Focus Firmware update?

I have updated without issues to v7930 NoDo.....I do not recall any Samsung firmware updates that Zune picked up on (in-addition) to the official AT&T/Microsoft released March v7930 NoDo update...
[Focus General] msg95:
After reading more on this forum and internet, I may not have formatted the card properly. Reset the phone using the "camera+volume+power" method and synced my music and photos. First time I installed the card, I only used the "settings, about, reset phone" method. So far everything is running same as pre-card install. I used WP Bench several times during syncing (but not at same time). With about 8+ MB used I got 3.25ish MB/s, around 9.5GB used I got just below 4 MB/s, and currently using 11.2GB out of 22.09GB I'm getting 5.6 MB/s. I have to note that once I passed 8+ GB, the zune software would give me the "device not responding" error if I tried to sync too much. I will post if anything changes.

Look at package and card is "Patriot Signature Line 16GB Class 4 PSF16GMCSDHC43P"
[Focus General] All5horizons:
Thanks. Had the rep check before taking, unfortunately it is rev 1.4. It was the last Focus they had at the time. He told me I could take it & swap it out for a 1.3 once they had more stock in. I'm not mess with the SD at this point.
[Focus General] hx4700 Killer:
I'm using the Sandisk Class 2 16GB card that AT&T lists as compatible with the focus on it's accessories page and its been fine.

Edit to add... so long as I don't try to do things like use the card in unsupported ways such as the explorer hack to access the card directly instead of with ZUNE.
[Focus General] jfreiman:
The storage card is still working great!

On the RARE occasion, I have had to wait a second or two when typing for the screen to catch up. But that's only happened 3x since the installation of the card.

I now have only 10.57GB free and use my phone for hours listening to music while cycling (bluetooth headphones - of course) No problems.
[Focus General] JamesAllen:
????

Not sure what explorer hack you are referencing, but I have had a 16GB SanDisk Class 2 since December of last year in my Focus with no problems. I installed the explorer hack that allows me to view SOME folders on my Focus with no problems. I would think that any explorer hack would only see folders that are "allowed" regardless of where they folders and files are installed, phone memory or SD card memory. From what I know, the phone sees memory as total memory.
[Focus General] hx4700 Killer:
It wasnt the hack so much as the fact that I tried to move some data from work to home one day and left about 600MB free. When I tried moving data off one file would repeatedly crash and reset the phone. Move it, copy it etc... no go. I was able to delete it but it was very precocious about it. I decided I wouldnt do that again.
[Focus General] RoboDad:
Just as an FYI for anyone looking for a card, Walmart has lowered the price on the SanDisk 16 GB class 4 card to $29.99. Just picked one up tonight.

32GB Patriot CL4

I've been running a Patriot 32GB CL4 card for about a month now. I haven't seen any issues which is good since I've been holding off on doing anything serious with it until I saw it was stable which it seems to be at this point.

I wish they would put the manufacturer's part numbers with the descriptor in the 1st post so I know what specifically to look for since there are typically multiple cards that could fit just the generic description.

Here's what i have installed:

Patriot 32GB CL4 - PSF32GMCSDHC43P

[Focus General] OklaPony:
About a month into this card and no problems detected whatsoever. Looks like they got the problem solved as far as I'm concerned.
[Focus General] RoboDad:
Almost two weeks now for my SanDisk 16 GB C4 card, with about 4 GB of the card used for photos, music, and apps (Zune shows just under 12 GB free memory). No problems at all.
[Focus General] Funkadube:
Generic 16gb class 4 been working for months!

Hello, I have an unlocked Samsung Focus, now updated fully, and my generic 16gb class 4 sd card from ebay has been working perfectly ever since I got it. No problems whatsoever. I suggest getting one, putting it in, having the phone format it, and then never take it out. heard about too many issues from people trying to change them out.
[Focus General] jayman713:
I have had the Focus since December and have been waiting for "approved" micro sd cards. I had tried 2 different cards purchased off of ebay and they were both counterfeit and crashed the phone. I have read many opinions and experiences from blogs all over the internet and decided to take that knowledge and buy a 32 gb micro sd card.

After installing I did the reset twice (read somewhere that helps). I now have a total of 37 gb of usable space. I have had the card in the phone for a week, I have about 28 gb of music loaded on the phone (definitely using the card). I have turned the phone on and off many times every day and swapped batteries, many users reported that this is when they had problems, when the phone comes back on data is gone and memory is gone. Not so with this card, everything is working great, no change in speed of downloads or games loading, music is always there and sounds great!

I purchased the card off of Amazon from BlueProton who is a certified SanDisk dealer. It is a SanDisk 32GB microSDHC Memory Card (Bulk Package). There is not a class rating on the card (class does not matter in this case).

I hope this helps.
[Focus General] dbG33K:
Bought a PNY 32GB C4 card from Best Buy. I haven't had any data loss problems, but the phone goes QUITE slow sometimes. I've filled just over 10GB and wpBench tells me it's getting 4.95 mb/s, but I've experienced occasional slowdown in normal interface, as well as frequent lag in some apps, and MAJOR lag in the game, Flowers.

Should I opt for a smaller capacity, more reliable card, or are these responses normal/acceptable?

EDIT: Also, when syncing Videos, and other large files with Zune software, it will load consistently for about 9%, then pause for nearly 30 seconds, then continue, then pause again. All for one video, just repeating that cycle.

EDIT AGAIN: Added a few more videos (12.02GB of 37GB) and the wpBench is ABYSMAL! Ran the test a few times getting 1.01, .89, then, get this, .29 MB/s. I'm not sure if the extra videos did this, or if the card is just unpredictable. Will now try rebooting the phone (Power Off, then On) and test again, then possibly removing the videos and retesting.

Okay, before even rebooting, all I did was lock, then unlock the screen and retested, and it gave me 4.36 mb/s. Do any of the other cards vary this much in speed? Boy, I would love to have a reliable card right now...
[Focus General] dbG33K:
Alright, so I returned the 32GB PNY Class 4 microSD to Best Buy, only to find that they didn't carry any of the ones recommended here. The only brand they stocked was PNY, and they didn't have 16GB Class 2, but rather Classes 4 and 10. So I bought the Class 10.

I've been using it for the day, filled it up to 8.89GB out of about 20GB and many of my above issues have been resolved! In wpBench, I'm getting around 5 mb/s consistently and my apps have been running fine as well.

I then tried powering it off, then back on, and lo and behold, all my data LOST. UGH!!! Why can't these things just work?!!
[Focus General] minori_aoi:
Currently using 16GB Class 2 bundled with my Verizon Motorola Droid (not sure which brand). If there's abnormalities, what's the symptom ?
[Focus General] firewolf006:
I tried a

PNY 16GB class 10 card and it DID NOT work

. I did a hard reset and all was well, until i used up more than the phone's 8GB of storage. Upon soft reseting the phone said the card was malfunctioning and it would not start without hard resetting again.

Out of curiosity i tried out a card from one of my older phones. A

PNY 4GB class 4 DID work.

After several resets i've seen no problems yet. The phone reports 10.88GiB total and 2.61GiB available

Another note, it may not be card related but before i installed any card into my phone it used to get finicky when the available space started to get low, like less than ~500MiB low

hope this helps
[Focus General] firewolf006:
ugh, one day i'm going to destroy BestBuy >:(

I bought a

PNY 16GB Class 4 card and it DID work

. After a few soft resets it seems like it's going to hold in the long run. Right now the phone reports 22.02GiB total and 11.81GiB free.

Hope that helps =)
[Focus General] woodbane:
I've been using a 32GB Sandisk Class 2 for about 2 months now with no adverse effects that I can see.Total storage after formatting etc. was 36.90GB, got about 18GB left. Mostly music, apps and games. (LOL, what else is there I guess!)
[Focus General] swtrader:
What SanDisk model # is the 16GB what seems to work? I see the SanDisk Mfr# SDSDQM-016G-B35A typically sells for $28 is this the correct one?

Thanks in advance
[Focus General] Dieabolical:
I purchased a Patriot 32g C4 micro SDHC card yesterday. The phone recognized the extra storage correctly, but when I was syncing music to the phone, the phone would not be recognized (disconnect from the Zune software) after I hit beyond the 8gig mark. I tried many times with the same result. My music collection is approx. 25g. I put my 16g back into the phone, and it would sync beyond the 8g threshold without any issue. I am going to return the card, and try a Sandisk class 2 or 4 32 gigger. By the way, my Focus is a Rev 1.3, software version 7390.
[Focus General] Dieabolical:
I went and got a Sandisk 32g C2 to replace the Patriot 32g C4. So far, no sync issues. I am deep into the storage of the 32g card (well apast the internal phone memory). There has been alot of feedback all over the web about the Sandisk cards working well with the Focus. I will post if there is anything negative that comes up, but so far so good. Stay away from generic crap, for sure, if you are going to make the 32g plunge.
[Focus General] Prerna:
I just switched from Android to WP7, using a standard SanDisk 2GB. IT seems rock solid in terms of stability and speed.

The issue is it only shows 35MB total memory, and 0MB left!

I did not format the card before flashing. Could it be the cause, and what is the solution?
[Focus General] ssuluh:
Sandisk 16G C4

+1 for Sandisk 16G C4. This is the 2nd day on the device halfway into the card and no problem. I soft reset at least 10 times and data still there.:)
[Focus General] brettpfleiger:
Mango seem to be working better with my Kingston 32gig class 4

When I was running NODO my kingston 32gig class 4 caused my Focus to lag and sometime crash out of apps back to the tiled home screen. Since I have been running the Mango developers release. I am not seeing lag or crashes. Is anybody else seeing any improved performace with SD cards with Mango?
[Focus General] SuperSport:
Interesting you ask. I just ran WP Bench today and I got these amazing results on Mango:

data: 13.07 MB on both Main and Storage Transfer Rates

This is up from 4.9 MB using Nodo.

I'd say that's a marked increase in performance. :D And still no lagging, crashing, or data loss using my Samsung 16 GB Class 2 SD Card.
[Focus General] EnderPsp:
That's what I got too but I doubt that's correct (similar results and setup).

I couldn't get past 3MB with NoDo and I know for sure my SD is 3MB/s (class 2) so I suspect that WP Bench will test in Mango the Main memory as both Main and Storage, considering the OS sees the Main+Storage as one.
[Focus General] cloknem:
I am using the PNY 32GB Class 10 SD (P-SDU32G10TEFM1) with no problems so far.
[Focus General] EnderPsp:
Try filling it up past 8 and 16 GB barrier.

Can you please post your WP BENCH storage/main results? Also, are you on Mango beta or Nodo?
[Focus General] gsulliva:
Anyone? Seems like lots of people are using the SanDisk, which model #?

Thanks
[Focus General] EnderPsp:
No sure about the exact model but all who tried (including me) have reported success with Sandisk 16 GB Class 2. With Sandisk 16 GB Class 4 most people reported success and only a few had issues when, afaik.
[Focus General] kenikh:
After reading the long list of reviews for the SanDisk 32GB card (SDSDQ-032G-A11M), it became pretty clear that Focus owners are not having issues after installing this card, especially since May, when it seems that all shipped cards are Class 4. I went ahead, bit the bullet, bought it and installed it.

The net-net is that all of the new cards purchased from here don't seem to have any documented cases of issues. I have been using the card for several weeks, with numerous writes/deletes, I have restarted the phone numberous times and have had zero issues.

Some things of note:

- I formatted the card using the official SD card formatter, zeroing the card prior to use

- I run the Mango beta, which seems to have significantly improved memory management

I am very close to recommending this card with no reservations - I just want to get another few weeks under the belt. That said, there are no signs of weirdness. The phone runs great.

Here's the benchmark data from testing the card in Windows prior to install:

I hope this helps!
[Focus General] tytnlover:
The first card I tried was a Sandisk 2 gb random class. It worked with no problems. The next one I tried was a Sandisk 32 gb Class 4 sdhc. It gave me that black Storage card not working screen. Then I thought maybe I could try formatting it somewhere other than the phone, but nothing could read anything on the card...

It had me wondering, if I hard reset the phone with a card in there and it doesn't work, does it still affect the card? I didn't bother checking to see if the card actually worked before performing the hard reset, so is it more likely that the card itself was defective? Has anyone else had this issue with a card the Focus couldn't read?
[Focus General] wm.andrew.wilson:
The end of SD card issues/the need for this thread?

Did anyone else see that Mango developer build 2 has built in card compatibility checking? I got a prompt saying my card was incompatible preventing me from booting. It looks like they implemented major fixes for the SD card problems in mango. Build 7712
