4 GB Mini SD durability poll

Hello all,
I used a 4 gb mini sd for around 4 months without any serious issues (soft reset fixed everything for me.) Then, out of nowhere, the card just became unreadable. Couldn't access any data from it and I couldn't even reformat it. Completely dead.
So I started poking around about 4gb cards and found (like I probably should have done before I bought the card) that the current mini SD standard stops at 2gb. These "4GB" cards are really 2gb cards that have been hacked and reformatted to 4gb. Now, apparently this works, but drastically shortens the card's shelf life. It is said that most of them die within a few months, if they last that long.
I just wanted to post a poll regarding this issue. Hope this is of interest to everyone.

Well if what you are saying is true, then shouldn't the same apply to SD cards? I had used a 4gb SD card for 2 years in my Magician and Prophet without a problem...I think it was a Transcend.

I think it does apply to standard size SD cards too:
I looked at the Sandisk site and the only 4 gig cards that were being sold were listed as SDHC. Nothing on the official site over 2gb that wasn't high capacity. I was able to track down the Trancend card you were talking about from a reseller (and numerous other ones including Ebay) however, if you go to the official Transcend site you see that there are no standard SD cards in a 4gb size.
This leads me to believe that the info I have been reading regarding this is correct. If the manufacturers are really putting out 4gb cards, why are they not on their official websites?
But the point remains that these 4gb cards (hacked or not) do indeed work in the Trinity (as well as other devices.) It's just for how long that is the question. I just want to find out with what regularity these cards dying so we can judge whether or not it is a worthy risk to buy one and trust our precious data to it.
Matterhorn, I appreciate you relaying your experience with the 4gb standard SD card. Perhaps the hacking and reformatting is more stable in the standard size as compared to the mini version? Hopefully this poll will help us figure it out.

The label on the 4gb SD Transcend looks exactly like the official Transcend color scheme. The card itself is in blue plastic and the label is in vibrant colors with Transcend, 150x, and 4GB written on the label. I believe this is the same one http://www.newegg.com/Product/Product.aspx?Item=N82E16820208086. It also has a serial number stamped on the back. I really don't think it is a fake Transcend.
My Topram 4gb miniSD continues to faithfully work in my Trinity. I don't know anything about this ebay vendor, this link is just for info http://item.express.ebay.com/TOPRAM...320102528838QQihZ011QQtrZexpQQcmdZExpressItem. It came packaged like an authentic card, some others have no professional packaging. Perhaps it will give up one day, if it does I'll report it right away. I know there has been quite a few people stating that their miniSD cards have quit on them, which I'm sure is true, but I can't help but believe that the squeaky wheel gets the grease, meaning that people that have no problems with their cards are less likely to post results.

I've been using a 4gb card in my Trinity for about a month now.
Gave me a few problems with Media player at one stage. The MSME files for the library dissappeared and I couldnt get them deleted to fix the media library problem.
Put the card in my desktop reader and suddenly they appeared again!!
Since then - no probs. Have it well filled up with mixeded media and prog files.

I know I sound like a conspiracy theorist, but this still doesn't account for why 4gb standard SD (non-HC) cards are not on the company's official website.

Wouldnt it stand to reason that if they were 2gb cards "hacked" to 4gb they wouldnt have the capability to store 4gb worth of data? What you are inferring is the "Tardis" effect. Bigger on the inside than the outside which to my knowledge is not currently possible. A bit like having a normal sized mini car with 7 MPV seats inside. I think is just a matter of intermittent hardware to hardware clash/incompatibility not a 2gb hack.
Must admit,have suffered from the card corruption syndrome for the first time in my life whilst using the M700 trinity.Talk about heart attack!!!! The thing that makes me think it is a hardware compatability issue is that I have used that same 4gb miniSD in my wizard variants,prophet variants,treo's etc for over 7months no stress. Hence I know the card is good (thanx mobymemory!)

4GB Problems
I bought a no-name 4GB miniSD cheap on ebay. It worked fine initially in my Trinity, but only took a few launches of TomTom to get corrupted - "no maps found" and hundreds of smiley faces in File Explorer. I was always able to reformat and start over, but soon got tired of that. Strangely the same card performed perfectly when used in an I-mate Jam (inside an SD adapter) or when in a card reader on the PC. I got rid of the card and got a Kingston 2GB and have had no problems since.
I just got more TomTom maps and am trying to decide whether to take the plunge again. Anyone got any positive 4GB stories?

I do not have the Jam but tested on my XDAII and works perfectly!!
How can I format it?

well i have a 4gb trans. SD 150x it works in my other mp3 player now for a long time, but as far as mini i dont know
i got a topram atm and it seems like it worked for a format or 2 and died after didnt even get to use it in my pocketPC, sending RMA request now :/
i was really looking forward to hear more good news about the 4gb topram miniSD but i dont know atm

I think maybe the poll should be changed to include SDHC cards since that is a variable that is very important on judging the 4gb cards. SDHC cards work but are just not reliable yet in the current roms.

Now this is very strange:
Go to http://www.topram.com/
look at the picture in the middle right under "MiniSD" (orange background): The picture shows a 4.0GB MiniSD Card
BUT
If you click on the picture they tell you only the following cards do exist:
120X 2GB miniSD
120X 1GB miniSD
60X 512MB miniSD
60X 256MB miniSD
no 4.0GB MiniSD
What is this??????????
I tried very hard to find Matterhorns Card in Germany. No success. Simply cant find them. Not on any german online shop. Not in any real world shop. Very very strange.

Oh ye of little faith
I bought mine from an ebay shop. You won't find them in Germany because they are from Asia and they're not marketed here. It came in sealed plastic and looked very professionally packaged. As far as the web site goes...how up to date are half the manufacturers web sites on the web?...not very.

That's very good news. Thanks for that info!

good morning guys.
let me share some information i have about flash memory.
few month ago one big electronic shop in my ciy was offering usb flash disk of sizes up to 16 gb. in very cheap price.
alot of my frinds buy that memory.
after few days alot of them returen to the shop to exchange them becuse the memory damged.
some of them did not have anyproblem untile today !!!!!!!!!!!!!!!
the reason is .
these memory are just 4 gb memeory and haked to be like 16 gb.
so if u try to write one bite over 4 gb you will start write this bite over the first bite of card and you will damge the data on that bite. and maybe the card will not be usable again.
this hake is known to be used on other media before flash memorys.
it was used in some hard disk to foll consumers.
the same story here.
if u have a 4 gb Mini-SD . just try to put more than 2 gb and your data will be gone (bye bye bye). maybe the card will be not usable again .

This theory has been proven to be not true over and over again...search the forums.

hm, hello and from me..
I bought 4 gb minisd Albatron, and after 2 days, the card just stopped. I tryed to format it, but no success. The card just died. After that i read this topic and searched on the albatron site to find some mini sd 4 gb card, and i cant find... after that i exchange the card with 1 gb Kingston and since then - no problems at all.. And i think that this 4 gb minisd cards are really hacked and if you have luck - you may use it maybe 5-6 months.. but i really dont buy 4 gb card, until the manufacturer says that they have one.
Regards,

4Gb Topram mini SD - fine. I've used 2 of these and they have been OK.
2Gb Transcend mini SD - useless. Would corrupt in a few hours no matter what I tried.
1Gb O2 branded mini SD - fine.

I'm still using a generic 4GB card that I bought of EBay and its settling down fine after about 3 months use. although at times, it can be just about noticably slow.
I've had a lot of trouble with the card 'dissappearing' ow and again and the Media Player library going awol. However, the fix's for those problems are well published on other threads.
I purschased a Sandisk 4GB SDHC card hoping it might be a bit faster, th Trinity cant even see it!! So much for SDHC support.

32GB Class 4 Micro SDHC card problem

i bought a 32gb class 4 for my hd2 so i can run android off it, but when i insert the card into the phone. the phone freezez, wtf. i left it in there for half an hour and still nothing, the phone is still frozen. after i took the card out the phone unfroz and was working. i put it in my brothers HD2 and same problem, it freezez. i put the card in to a htc desire z and the phone picked it up, it looked through the files on the memory card. why the hell dont it work on my HD2. Now i bought this card from ebuyer. i hope it works man:
http://www.ebuyer.com/product/218439
any ideas why it wont work and makes my fone freeze. looks like i will have to save the 32gb for a dual core nvidia tegra 2 phone.

does it freeze when you launch android or just freezes in winmo 6.5?
if it only freezes when you are launching android, backup the card then format it in winmo (you'll find under settings) and restore all files to it and give it a try

That link takes you to a 16gb class6 SDHC card made by Lexar.
It also happens to be the highest capacity card they sell on that site. Trust me.. I looked.

Download h2testw, run a full test of you micro sdhc card and make sure it's functioning properly.

dont you read anything. i said now i bought this one with the eprovided link from ebuyer

it freezez in winmo.

Just in case someone is still having issues, this is what I experienced.
I bought a Sandisk 32gb micro card, formatted (quick) with windows, put it in the HD2, and had nothing but problems (many hours of trying different things) trying to watch AVI's, or even install larger CAB's.
I read here about the SD assoc. having a free format program (SDFormatterv3.0.zip), I downloaded it, installed it on my WIN7 machine, did a quick format, not much change, did a full format (took over 3 hours!) card now works perfectly. Amazing.
I sure this is not the case with all Micro cards, but it sure helped me. Oh, I did the formatting while the card was in the phone, the card was set as "Disk Drive". (settings, other, USB)

I can vouch for the official format program fixing problem cards.
Sent from my Atari 600XL using cassette tape and a stamp.

Well an update. The program does a very good job on formatting the micro card, but it does not detect a fake card! H2testw.exe does, excellent little program. Turns out my 32gb card was 2Gb! Windows and the SD format program both reported it Ok, but If I wrote over 2Gb, files disappeared or didn't work. (doah) just couldn't believe I got ripped. Anyway, buyer beware, and check those cards before you loose important data.

32 gig card
As far as I know the hd2 does not support any higher then a 16 gig micro sd.

It supports sdhc so up to 32GB.
Sent from my Atari 600XL using cassette tape and a stamp.

Shows what you know. Almost all the HTC phones produced in the last two years have the abilty to use 32gig cards.

That's what I said... Unless you're replying to another post, in which case - quote, if it's not directly above yours.
Sent from my Atari 600XL using cassette tape and a stamp.

Well I finally locked onto a 32gb card. Got it from Buy<DOT>com, quite a few for under $50 now. Ebay... <sigh> 99% of them are fake, defective or scams.
My Tmobile HD2 runs great with a class 4 32gb card.
All I can say is avoid Ebay for your cards.
For those running on Tmobile firmware (I do still) there is a new ROM release that radically improves battery life, I am getting 100% more op time. I am not a heavy user. (5 days now, vs 2 before)

Micro SD cards weird issue

I've just experienced a weird issue with the SD cards.
So whats happen.
After I started to use Android on my HD2 my 8GB Kingston Class4 SD card just get a bit small. So I decided to buy some bigger one. First I bought a 32GB unbranded micro SD but soon I found that HD won't take that much so I sold it straight away.
Than I've looked around here on XDA and I found that so many guys using 16GB without probs.
So I bought another SD this time 16GB unbranded ( to keep the cost low) Class10 what's probably fastest at the moment.
I backup my old 8GB card ( just copy all content into my comp ). Than copied all content onto new 16GB card and sticked it into HD2. I thought all should work without any probs but it wasn't.
Phone was really slow, unresponsive, many fc.
OK I set its just need to flash the ROM again so I deleted content of .data folder and did a fresh clean flash with all caches wiped. I thought after this it have to be OK but again it wasn't.
So I started to be a bit worried by that time than I decide to buy another 16GB card but this time I spend more and I bought a Kingston 16GB Class4 ( same brand and class like my old 8GB ). That was for sure it will work 100% if my old works fine. And many people using 16GB, also one of my friends got 16GB SanDisk with Jaws MIUI ( I flashed it for him ).
So today I received that new 16GB Kingston Class4.
I did the same again - backup/restore all content and surprise *** NOT GOOD again; slow, unresponsive, fc's
So reinstall again and surprise *** NOT GOOD again; slow, unresponsive, fc's
I've almost rip of all mine hair (I mean the few bits whats still there )
So after all of this I came out with the last chance idea....
To do total wipe - thats included
- delete all data from the card
- flash stock Winmo ROM
- flash latest MAGLDR
- flash latest CWM Rec.
- flash latest Jaws MIUI
.......
.......and surprise *** All is OK, the SD is working just fine, finaly
So weird and I don't understand this.
I know this was probably long reading post but maybe someone have an explanation for this or some one have a same issue like me and can use this like a last help.

Where did you buy the card from? The market is flooded with low quality counterfeits, so always buy good brand from reputable source. I always buy sandisk, and never had a problem.

well normally I buy a Kingston or Sandisk. This was a first time I get unbranded cards but anyway at the and it wasnt caused by card quality cos this Kingston didn't work, only after I've done all that steps all is OK.

I have the same issue with Kingston 8GB Class 4 SD card, it is very slow, unresponsive and sometimes it doesn't come back from lock screen... i have to restart it... right now i am using Scandisk 4GB Class 2 card, it is OK but my phone heats up pretty quickly...
How can i resolve the heating issue... any idea?

Well, Kingston re-brands their SD Cards, so you never know what you're getting. I have a few and you can just pull the "Kingston" labels off to see what the original manufacturer is, and often thats just another rebrand anyway. I'll assume they do the same with their Micro SD cards.

maybe its a fake card
If u want to verify your card genuine or not, go to fake-memory.com,
u can download some tools over there.
your card might be ok today, but once its near full, you will see weird thing happening again, I also bought OEM card. (unbranded)
lucky my "32GB" is really a 1GB, so I spot it early.
Just get refund from seller through ebay.

I would have think about the SD also. But due to the solution you apply, I think now about a corrupted file somewhere. Maybe at a low level of your NAND.
That's just a thought (so maybe not so helpfull).
We play sorcerers with our phone... so I'm not surprized this happens.
I also have a corrupted SD few times. The validation processes are important and I don't think we can do the same as manufacturer on this point.
As the first level loader is never touch we can't brick our phones but this is the price to pay. DO NOT PUT VITAL DATA WITHOUT BACKUP IN YOUR PHONE !

What I meant was where did you buy your kingston from? Kingston cards counterfeited alot. Kingston is also known to sell many low quality or defective cards. Kingston doesn't do any of their own manufacturing... they just rebrand cards, so many times they get bottom of the barrel cards. I won't buy kingston anymore after I did some research. Sandisk actually owns their own factories and create the chips they sell... they probably keep all the good ones for themselves and sell the bad quality or defective ones to kingston. I really don't understand how kingston is known as a good brand-name, because they shouldn't be. Buy sandisk cards from a reputable seller.

I got 3 micro cards
1. adata 16gb class 10
2. pqi 8gb class 6
3. sandisk 8gb class 2
All cards are without any errors and works with WM6 well. Unfortunatelu on Android with ext partition isnt so good.
There is no single rom using ext partition and working well on my class 10 card!!!
On PQI some works ok, some not
And on Sandisk every rum is running without errors.
What's going on? Ported android to HD2 probably is not 100% compatible with HD2 card reader ;-((((

I thought all is OK.well it was a day and now im back to sh*t.phone its slowing down,sometime cant wake up from lock screen or have to wait 30 or more seconds. i dont know whats the problem. looks like i have to sell my card and buy another one.this time i go for Sandisk but 100% genuine. its gona be expensive but what else i can do :-(

Maybe you have tried before...
Why don't you try another build before buying another SD? This at least will cost nothing. Just to be sure.

it seems we're all agree to say that Kingston sucks...

I've already tried and its same. Its definitely a card issue.
Damn, I have to buy another one, 4th card in week or twoo
will see, hope die last...

[Q] Should I give WP7 a go? For the second time.

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.

Alright my man no need to freak out. I guess this isn't the thing for me since I don't believe in luck and I don't feel like wasting my money.
Thanks to the others for your replies.

I like you had the same problems with a few SD cards. I remembered seeing a post going back about Sandisk selling SD cards as being HD compatible. So I did a search and found the cards and their model numbers, bought one and have had no problems at all, no lag and WP7 runs perfectly!

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.

Thanks a lot my man.

I got a Sandisk Class 4 at radio shack (good sale at the time) and it works perfect. Not a single hicup.

I am using the original class 2 16GB card that came with my HD2 and it works flawlessly.

Swapping out the MicroSD card of HTC Surround

Ok... I'm not so sure If i was supposed to make a new thread or reply to an old one... but If you replaced your MicroSD card, then what kind did you replace the 16gb card with? I put in an older 8GB C4 card and my phone is not working as well as before. It is not responding during sync and it opens applications a bit slower. Every time, after about 5 minutes into the sync operation, it stops responding and I have to reconnect it to my computer, and I fear that it is overcharging the battery.
So just curious, what brand, model (if you have it), size, and class, are you using currently?

Hi Kuree,
The first time I replaced my SD i used a Lexar 16GB Micro SDHC (it has a 4 in a cirlce on it as well). This one worked perfectly, syncing and there were no slow downs what so ever.
The card i have in my surround now is Also a 16GB MicroSDHC (with a 2 circled on it) this card also works perfectly. i'm not sure on the brand name as this one doesn't say it but I'm pretty sure it was a Lexar Mobile version.
I've only used 16GB cards so i can't exactly tell you if the 8GB card is the root of your issues.
Hopefully this helps you out!
If you have any more questions let me know and I'll see if i can answer them.
Take care,
Coockoo

problems....
I guys, sorry to resurrect an old thread. I'm having issues with upgrading to 32g... after hard resetting the phone and setting up time, the phone just gets stucked in "installing apps". It just seats there.
Any suggestions or things I should try??...
Any help will be highly appreciated...
thanks

Hi,
Is "ADATA" micro SDHC 4
They told me (were I bought this) that this card should work.
Now I can't even read or format the SD card....
Thanks!!

I didn't even know the surround had a memory card slot, where is it?

Any chance to revive the "adata" card?. I would really hate to trash 26 bucks...
To LKMR, search youtube, there is a nice tutorial on how to expand the memory of the phone.

Click to expand...
Click to collapse
In this video how to disassemble, locate, and swap out the microSD card in an HTC Surround Windows Phone 7 on AT&T. Please note that undertaking this project will most certainly void your handset's warranty.

I used a Sandisk Class 4 32GB. No problems at all... WELL worth the price and effort. They are also VERY cheap if you keep an eye on Deal a Day. I've bought 4 from there so far, the last was like $20.
