[Q] sandisk 4gb class 2 - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

I have a question: a SanDisk 4GB Class 2 can work on wp7 hd2?

Yes, I have one and it works just fine. My everyday sd card, though is a 16 gig class 2 no reboot problems or sleep of death
If you look here:

and here:
http://forum.xda-developers.com/showthread.php?t=912904
you'll find massive lists of compatible sd cards
If I helped please hit the thanks button!

I have two. One was not recognised at all, the other one worked fine, although I only used it to set up an 8 gb card for dual booting, so not sure how it would have performed with WP7.

Thanks now i am going to flash my hd2 to wp7. I hope this works for me

4 GB 150X SD Card tried on O2 ?

I am about to buy a 4 GB 150x Class 2 SDHC Secure Digital Card for my recently bought O2 Neo handset. I would like to know if anyone has tried this earlier and knows if it works.
Umesh
O2 Neo
i have a-data 4gb turbo sd 150x and it works well
Thanks Speeed. Do you know if that is a Class 2 SDHC. I remember reading some post here which said a SDHC 2.0 format might not be compatible with HTC Prophet.
is SDHC working in a prophet?
Hey Umesh, I do have exactly the same question. I already have a 1 GB SD card. But now I need to upgrade and I am wondering if I can buy a SDHC class 2 or even SDHC class 6 card. Can you please post your experiences.
ADVAthanksNCE, Peter

I have the Transcend 150x 4gb SD working in my Prophet for almost a year. The only issue is one that applies to all SD cards and not just the 4gb, that is today plugins sometimes don't like to be on the SD card, otherwise everything works perfectly. It seems to me I remember at the time I bought my 4gb SD card there were some models that had issues with the Prophet. I guess you could just get one of the cards that has already been proven to be compatible.

Topram 4Gb
I have a Topram 4Gb 150x sd card and have had no problems. I got it from Ebay.
please note it uses SD 1.1, which is the maximum the Prophet supports.

Hi,
I have a samsung oem 4go 150x, bought on ebay from fastmemoryman, and it is also working perfectly on my prophet.
Topram and Soho failed. Still looking for a good 4GB card!
Hello guys,
Here's my experience with 4GB SD card dilemma using a Qtek s200:
1) Topram 150X:
*Works ok till 2GB but data written beyond 2GB can not read back.
*Surprisingly there's no error after chkdsk, xp-scan.
*No error when writing beyond 2GB but data is not really written.
*Original content of the sectors do not change at all.
*Deep analysis under WinHex states defect starting at sector #3964927 of about 8 million sectors.
* FAT16 and FAT32 all formatting combinations possible on Qtek as well as XP which is surprising. No error using Panasonic SD Formatter as well. This card doest not react to any write operation, even if it fails !!!
SOLUTION: Created a 2GB partition using WM5torage + XP and bypass defected area.
2) SOHO 150X:
*Looks horrible with 5th class sticker misaligned.
*Comes with 90MB of defected sectors already marked bad in FAT.
*Healty reformatting impossible.
*All sectors beyond 1GB are unreadable & unwritable.
SOLUTION: Sent it back to the seller.
QUESTION TO ALL POSTS CLAIMING TRANSCEND & A-DATA WORKS WITH NO PROBLEM:
Of course the 4GB SD's are recognized well when insterted in Prophet. But did you go beyond 2GB and up to 4GB? I strongly need someone who would confirm having written full 4GB and able to read it back with no data loss !!!
I think just inserting the card and seeing 3800MB something free means NOTHING and you should load the card completely without no data loss to be sure everything is OK.
Many posts claim problem with camera not saving to card. No sense anymore, it's not related to the cards but the cam.app as the free space calculation issue is well known now.
Waiting for some good news about Trancend and A-Data which i want to try asap...
SHHC not compatible with Prophet
Not yet tried but given all the information on various sources, Prophet has no chance to recognize any SDHC card. When inserted we will probably won't see anything. Like a RAW card.
The most logical explanation is that the CSD layer of SD2.0 is organized diffently than SD1.1.
Didn't see yet any opportunity to use them with a future ROM update. The hardware limitations of the reader on prophet may be the cause.

Friend. I have been using the Transcend 4gb 150X with my prophet for almost a year and let me tell you that baby is full!!! I have my GPS maps, a few videos, some big apps, and the rest filled with as much music as I can cram into the thing. It works without any problems at all, I also specify images to be saved directly to the card with no problems. I am not the only one that has reported compatibility with the Transcend.

I'm using 4go SD card for more than a month... it is almost full and no problem with any kind of data...
So, it work perfectly.
For those than can't save photos on SD card, this has nothing to do with the SD card format. It depends on if you've unlocked Ext rom or not. It depends also of the rom you've installed on your prophet, some home cooked rom than have native unlocked ext rom will show the same issue.
4GB SD cards on Prophet
Thanks matterhorn for making it more precise. It's very nice to hear such clear feedback.
...and Cedric, are you also talking'bout a Transcend?
I guess you both use your cards on the PC using regular card readers. 2GB and FAT32 compatibility should be enough o cope with 4GB. If the card is healty, i see no reason why a recent, non-SDHC reader would not work with 4GB SD.
I also guess you didn't have any problem using full capacity after re-formatting. Reformatting should not be a problem for a good 4GB card to become bad.
I think i'll give another try with Transcend which is a reliable company and registered to sdcard.org while SOHO and TOPRAM are not. In my language, we call them MANUFACTURERS WORKING UNDER THE STAIRS.

I use an normal SD card reader to format my card in FAT32 using XP every time I change my ROM, just to make sure there are no hidden nasties to cause problems. Newegg.com has good prices on the Transcend .
Also that tip about the unlocked extended ROM is a good one. When you can have 4gb, who cares about a few megabytes.
So can I assume to confirm the usability of a 4 GB card on my Neo -
If I slide in the 4 GB Card and it shows full memory (4 GB) as available in Memory Status --> Storage Card - that would imply that the full card is (read/write) compatible in the device?
Matterhorn, is your working 4 GB card SDHC 2.0 format ?
Practically, at best I would have only about a couple of minutes to test the 4 GB card at the store where I buy.

Let's put this to bed...Does SDHC work in Trinity?

Just wondering from users who have SDHC cards: do they work well in Trinity or not? I have read too much contradictory information...some say yes others say no. Let's settle this once and for all. Thanks!
Hi PSargent,
I'm using a SanDisk MicroSDHC 4 Gb with MiniSD adapter.
After applying "miniSD HC Patch v2.2.cab" it worked, but if I soft-reset the device with the card inserted it disappears. I have to remove it, reset, and re-insert after boot.
I'm still trying to find a way to make it work better.
Best regards,
Paulo.
I'm using the Kingston 4GB mini SDHC Flash Card Model SDM6/4GB.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820134518
No problems at all. I do have a strange issue where sometimes when I take out the card, when I reinsert it it shows as a new card (Card2, Card3, etc.) which can throw off some of the programs and email/internet storage. Reseting the device and running the SD fix usually fixes it though.
The Class 6 seems to be faster than my old Class 2.
Good luck all!
Mike
Works a treat for me
I run with a Sandisk 4gb in a mini sd adapter and it works perfect for me with no errors. It also loads files pretty quick too.
SanDisk MicroSDHC 4 Gb here. No problems for months. Touch wood.
I don't take it out as I don't need that, though.
MiniSd HC
I have a SanDisk 4 Gb mini sd and is working very well
So many threads with no concrete answer.. some say it works, some say it doesn't. As soon as more than one person says it doesn't, I suspect that there is an issue. Is there a fix that works 100%? Does it depend on the ROM you have flashed?
I suspect the truth is NOT out there.... Or does this thread need updating?

Problem with micro sdhc

Hi guys! I recently purchased HTC Touch Pro and A-data 8 Gb micro sdhc class 6. My laptop recognizes the card and I format it to FAT 32, so I think the card functions properly. The problem is that the device does not recognize tha card. I updated the ROM with the latest official release from the HTC site , and I was happy finally to see my card. The problem is that after restart, the card is invisible again. Can anyone help me? Maybe the storage card is faulty after all?
Possibly man, i am sure you have another card in there. Test it, if all is ok with it, then exchange your 8GB if possible....
The same thing happened to me; I don't know if it's faulty though. It is recognized at first, and of course I can transfer files from my laptop.

incompatability with SDHC
There is a known partition problem that can destroy your Micro SD (or any other size SD) if you every stuck it into an older reader that does not support newer sizes (any HC, or even standard SDs over 1GB).
Old readers can show your newer SD-family cards, and APEAR to work, until you fill them up past the size the old reader supports.
FOR EXAMPLE:
my old laptop has a built-in SD reader. Back when I used the HTC Wizard, I bought a 2GB miniSD, and dumped files to it from my laptop. Little did I know, the built-in reader only supports SD card up to 1GB. It worked back and forth many times untilI crossed the 1GB line (filled teh SD past 1GB). Then files disapeared or could not be accessed randomly. Kindgston told me it was a known issue of some older devices (readrer/camera/etc): the older device messes up the partition, which you CANNOT fix yourself: reformatting the messed0up partition does nothing. Ship back to manufacturer to fix. Now I'm careful to avoid the built-in SD reader
So I would advise: fill your microSD up aver half-way, and see if you desktop/ laptop has problems accessing files sampled from all over the chip. If it does, this is probabaly your problem.
I think it's just the card/brand itself. The HTC site lists card brands and sizes that have been tested and proven compatible, and the A-Data 8GB isn't one of them (although the 4GB SDHC is compatible). Sandisk is the only 8GB card that's supposedly compatible, and I've pretty much found that out since I had no luck with an A-Data 8GB but the Sandisk works flawlessly.
When I first copied files over to the A-Data and put it in the phone it didn't recognize it at first, but after a couple times of taking it out and putting it back in I was able to read and write to it in TotalCommander, but when I went to play music files the player froze up solid and the card was no longer readable until I did the in and out thing again. Bottom line was there was no way that card was going to work right in the phone, but as soon as I started using a Sandisk I never had a problem.
same thing happen to me
i think the phone will not recognise class 6 memory card
i will try sandisk 8gb class 2 when i got a chance

my touch pro two times had the same problem.The sandisk 8gb microsd HC (class2)collapsed.I can do nothing.My computer doesnt recognize the card.I cannot format it also.Does anybody can help me .What can i do.Thanks.
Card doesn't work in my Fuze. Oh well, I'll find another use for it.
Wierd.... I have two Adata 8GB cards, one works in the Touch Pro, the other doesn't. Both of them work in my Sharp EM One.
hi ive been looking like crazy to fix this problem but this seems to be the only post close to it.
i recently got a transcend class 6 4gb micro sdhc (listed on the website as compatible) for my htc fuze. the fuze (WM6.1) has been updated to the new rom version (5.xx).
i put it in nothing happens. it work fine on a computer (via usb reader). i have a kingston 2gb micro sd that works fine (but is used for another device). I really want to get this one to work so its not a waste.
so far ive tried reformatting to FAT, 64K and FAT32, 32K (via windows vista formatting).. none of which work.
really annoying, i dont have any other device that uses this card and i specifically checked this brand and type with the htc fuze and seems like everyone having no probs with it.
any other things i can try? is it a faulty card maybe (but it works through usb reader)?
I am having problems with the 8gb class6 cards as well. I have tried the Adata and the transcend cards. Here are some interesting things I have found.
1. The energyrom series of roms seems to be the only rom that lets me see the card.
2. I can't access the card until it the rom loads.
3. I can flash roms from the card even if I cant access them from the phone.
I did see there was a utility to help load SDHC cards called SDHC_WM6. I was never able to get it to load right but it indicates there is some kind of software driver that might help these cards.

I saw this utility too.. but its for windows mobile 6 not 6.1.. when 6 came out it had no support for sdhc so that thing came out, 6.1 should have support from the start
of course that didnt stop me from trying it anyway... doesnt work
I have a 8 gb Sandisk- Works flawlessly. I have a 16gb Adata( class 6) that worked for awhile then stopped. Put the 8gb- works, 16gb doesnt. tried different ROM- Still same effect. I has to be the Adata card. I am going to try a 16 gb Sandisk when my funds are available.
Oh- the 16 works fine in the microsd/SD card reader......
SDHC Class 6 works in HTC Jade
I have a jade and both cards that refuse to work with my fuze work just fine with the htc jade. I am not sure if it is a hardware problem or an issue with some software such as the sdhc.dll.
My thought is it is probably software. Why?
First the class 4 cards work just fine. In fact I am currently using a Dane-elec 16gb class4 card.
Secondly I am able to get intermittent class 6 cards access if I use one of the NRGY roms.
I have been using a 8gb Adata card that I bought from newegg, and it has been working flaslessly since november.
I recenlty bought another 8gb Adata from meritline, and this one does not get recognized by the fuze.
I then read in the above posts that somebody used Total Commander to copy files, so I opened up Total Commander, and the card is shown there.
I closed the the program, and now the File Explorer can see the card as well.
Maybe you can try the above steps and see if it works.
edit: actually, I have to plug in and out a few times for the phone to see the card...
I also have this issue with my transcend 8GB class 6 microSD.
HTC Touch Pro (T-Mobile), upgraded to EnergyRom. After upgrade, able to work perfectly. After few hours (the phone of course went into sleeping mode), then the phone was not able to read the card, so starting application installed in it makes the phone hangs.
After a while, the application (10-15 mins) was able to start, then everything is normal again. Very confusing.
At the moment I am assuming it's due to the sleeping mode, somehow the phone (software??) was not able to 'resume' reading from the micro SD.
Note: Previously somehow it clashed with the keyboard mapper software (pro_fuze_keyboard.ZIP), then I uninstalled it, then it was fine. Then I install another version of keyboard mapper (Shlomki TouchPro Keyboard in Fuze ROM.cab), then it's fine again, so I now stick with this mapper. However above issue is still happening.
I read some thread about changing some registry (pnp** set to 8196), so I set it. However still the problem persists.
I haven't tried other suggestion to tweak other registry values. Here's the thread on Hermes device: http://forum.xda-developers.com/showthread.php?t=294324&page=29
I am wondering if it's really class 6 problem. Is there anybody having the same issue with 8GB class 4?
Note: my PC can read the card without any kind of problem.
I put the microSD into N95 also without any problem.
and i have the same problem to touch pro will not recognize my sdhc 4GB class 6, and i have no problems with 4GB class 4.
HI Bobby,
Were you able to get the Transcend 8gb Class 6 work on the HTC Fuze? I have the same problem. I upgraded the rom from the HTC site and I could see it. But later I plugged the card using the adapter to the laptop to copy some files and when I plug that back into the phone, it says "Not Installed". My happiness of not losing 20 buck was only for a couple of mins Any help is appriciated?
Can you give me download link for the energy rom which actually worked with the card?

I had somewhat of a similar issue, wondering if anyone else has seen this?
8 Gig no name brand MicroSD card in my TouchPro, all of a sudden I had less than 1 gig left, using Resco I couldn't see a thing taking up all that space but it was all gone.
I put the card in the transflash adapter and looked at it on my desktop Windows Explorer and saw the following folders in \Storage Card\Program Files
one directory named (*#LD*))#KDP|} with some text after it
another directory named (#*(Y%*(#(*#*(@#kKD* with some text after it.
NEITHER directory could be renamed, moved, deleted, or anything.
Formatting the card hung the format process.
Finally, I put the microSD card back in my TP and all of a sudden Resco Explorer saw these directories and so I just deleted the Storage Card\Program Files directory (no programs in it) and formatted the card and everything was fine.
Anyone else ever seen this?

Does your SD card work perfectly with Windows Phone 7?
If so, which capacity, brand, model and where did you buy it?
If not, what problem did you run in to, and which capacity, brand, model and where did you buy it?

doesnt even work with magldr?? try formatting it on pc using panasonic sd formatter..
when it starts working on mass storage mode then perform the test on whether it will work on wp7 or not
----------------------------------
and to OP, transcend 2gb has issues for me.. sometimes wifi doesnt work.. sometimes it does but then wp7 gets really laggy and sooner or later just turns off (sometimes even hardresets)
multiple hardreset retries and it always ends up with the above issues.
Got mine with my HD2 TMobile usa, Scandisk 16 GB HC , WORKS EXCELLENT
Kingston 16gb, class 4 works fine. No problems... At least, not yet...
kingston sdhc 8gb class(4) - capacity avaible but phone have lags. reflashing wp7 nothing change
kingston sd 1gb - work fine
Kingston 8 Gb SDHC (Class 6) - Works great.
SanDisk 2 Gb - Works Ok.

I've tried that. It seems that there is an issue with MAGLDR - android, windows (PC) both see the card and read from it fine.
Perhaps MAGLDR doesn't like 32gb cards?
let me tell you..
I formatted my sd card in a thousand ways with all sorts of programs
NOTHING WORKED
you must have your SD card inside the phone when installing WP7,
then WP7 customises it and you are on.
Really strange though, I can sync in Zune but I can't view my SD card when I get it out of the phone.
Sd not working
I have the replacement SD from Samsung Class 2 16GB
It works with WM and Android, but not WP7
Honestly, I cant even find the location where I see the SD in WP7.
I keep getting the "Out of Space" message and I have to reboot to even get text.
Any ideas for some of this?
[UPDATE]
Fixed after reformatting the SD using my Camera, Then putting in the phone, and Re-flashing WP7
If your SD card was inserted when you first installed WM, then it's simply incompatible.
On the first boot, WM will format the card and initialise it for use. If it's not compatible, no go.

There is no pattern here.
Opening up this 2nd thread about SD cards is pointless and serves to do nothing but confuse, as it has been shown that two people with exactly the same cards can get very different results.
Suggest people just buy through trial and error/returning incompatible cards while waiting for some WP7 certified cards to come on the market. The fact that they havnt yet says alot.

Class 10 Micro SD Card Issues

Hi, I have been having problems with my Class 10 Micro SD, sometimes it would appear as corrupted, not detected, etc... Most of the time all I have to do is reboot and it would work ok again.
I'm using the latest MIUI ROM by langthang with this Class 10 Micro SD. I tried to reformat and partition (for A2SD) the card several times at PC using some utilities, tried also as well with the Recovery and still, same bahavior.
I have no problems using my 16GB Class 2 Micro SD, makes me think Class 10 Micro SD's aren't really compatible with Android, I tried "Googling" and some were also having issues.
Inputs anyone? Thanks!

Hi,
What is the make of sd card?
Generally brand names like Sandisk and Samsung make the best Micro SD cards, Lexar too are decent enough too, cheaper versions are tempting but ultimately wont last as long.

It has a local branding of a popular store here in our country. But hey, I think it works ok with PC, I got no problems with it when inserted in a card reader on a PC, even tried watching HD movies just to stress test this micro sd, and never gave me problems.

Hi,
The reason I ask is that there are known issues with unbranded cards in Android.
Sandisk and Kingston are ok.
So,therein may lie your problem.
As far as I understand it ,class does not come into it either.It's all about READ speed.

The reason I ask is that there are known issues with unbranded cards in Android.
Sandisk and Kingston are ok.
So,therein may lie your problem.
As far as I understand it ,class does not come into it either.It's all about READ speed.

Thanks for the input bro, appreciate it!
Format the disk to default 4k, single partition config... that should work fine...
Of course stuffs from good brands will always be better and will have longer warranty and reliability. But as I faced similar kind of issues where I re-formatted my sd card with 32kb file allocation size, my android was unable to detect it. The reason I later realised is that android has stripped down version of everything including the underlying linux, so I formatted my sd card with standard(4kb) allocation and its working flawlessly now! So I would suggest to remove the partition and other complex configuration for the sd and format it to plain default config and its should work fine! All the best....
