Does anyone know the biggest sized memory card you can put in the XDA Mini S?
I currently have a 2gb mini sd card in it - I saw you can buy 4 and 8gb cards - anyone know?
Much appreciated and thanx in advance
Some 4gb cards will work, but you have to make sure they are not the ones that are high compacity cause they are formated differently. The 8gb ones will probably not work at all. There should be a thread around here somewhere that has a list of 4gb cards that will work.

oh thanx so much
I read on the first link that there is a hack for the Treo 680 which works for the Treo 750 that allows one to use SDHC. How does a product which is supposed to be incompatible with a newer technology, become compatible? Can the same basic principle found in this driver be applied to WM5 devices such as the Wizard? Is it something in the hardware for the Treo only?
memory card query.
i bought a 2gb kingston card for my mini s 5 weeks ago and had no probs at all until today, i checked my mini this morning and it says there is no card installed, i checked the card in a friends mini and in a nokia and none recognized it used my mates card and my mini picked it up instantly. did my xda kill the card? i did take the card out last night twice while i was putting some data on to my friends mini, and i never checked it after id put it back in mine last night.
i guess what im asking is do you think if was user error or a bad card? as i want to order a new one asap, and dont wish to order the same make of card if it is due to the cards incompatabilaty with the mini. however if it is due to me being a ham fisted fool, il order the same, thanks in advance for your help on this
More than likely your cards not bad, it just lost it's format. The easiest way to fix it is to put it in a card reader and reformat it again. I have a 4 Gb card and I pretty much have to do that on a regular basis and when it decides to lose it's format my wizard doesn't see it at all either.

if it is broken, don't kingston do a lifetime guarantee? and if they do you don't have to buy a new one, just get it replaced

This site claims that there are problems with the sd card slot in the 2i - and the symptoms that they give seem very similar to the ones I am experiencing. Can anyone confirm or deny this? And if its true is there anyway of getting around it?
Thanks
http://www.digireader.com/view_blog.asp?blog_id=208&author_id=2
as i long user of the 2i I can say without a doubt there is a problem with the sd cards as i suffered for over 3 months or more of pure frustration and almost throwing the thing away .
but in the end it was down to the sd card speed ,it doesn't really matter what size you have but it's the speed of the card at the moment i am using a 512 transcend 80X card and it has been running perfectly for the past 4 months or so without any problems .there have been plenty people who have now tried the transcend card and found it to be well 1 of the best so i would recomend you buying 1 of these asap ,if you do a google you should find a place selling 1 of these but just make sure it's has a speed of 80x or else you will have the same problems ..also if you wish to get a bigger card the 1meg works okas well
Hmm, I can't say I'm at all happy with that. I have now borrowed a 512mb card and magically all my problems disappear. its the same make and model as my 1gb card so I can't see its a brand issue.
Are o2 aware of the problem? If they are then I think they're breaking the law by continuing to sell the thing.
Does the problem exist with the 2s as well? If not I might go back to o2 and insist they swap it over...
Thanks for your reply
Hi.
I've had an XDA IIi for a few months and had lots of problems with the phone freezing (especially with tomtom 5). The problems got noticeably worse when using "turbo" mode too.
I emailed tomtom for help with navigator and the strange locking up. After a month, they replied to me and said that the pda must use 80x cards or faster... i bought an 150x 2Gb card and haven't looked back...
The phone can now do it all... i use ttn5 with traffic addon whilst driving and use pocket music to play mp3s at the same time and i'm still able to answer the phone to accept calls...
the only problem i've had with a 2Gb SD-Card is that i can ONLY read/write it in the XDA IIi - no other PDA will touch it and no card reader will recognise it.

What brand is your card?
Having already sprung for a 1Gb card I'd hate to have to spend out again becasue of inadequacies in the xda hardware... however if it was an upgrade to 2Gb I might be able to better justify it.
Perhaps this info about card speeds should be posted in the FAQ so that new users have at least some warning of the 2i's problems with SD...
mine is an "a-data" myflash 2gb from here: www.emartbuy.com
£91.65 inc VAT
hope this helps you!

I would just like to say thanks for this topic, the two problems i've had with the PDA2 (XDAIIi) since i got it earlier this year have been fixed by taking out my 60 speed 1gb sd card.

problem 2: http://forum.xda-developers.com/viewtopic.php?p=166348
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?

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.
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

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)
Hey Buddies from all over the world....
Flashed WP7 on HD2 with the original SD-Card, which came along with HTC's HD2,
so far, so fine....
Tried the same with my Kingston 8GB SDHC, but WP7 won't be flashed....everything is soooooooooo slow and I have the feeling that the flash process gets stucked...
So, how can i formate this SDHC to be compatible with WP7 ?

Try sdformatter. Then inserted into the phone and do a full reset.
its worth pointing out that there is no "right" SD card that will work, well there is but not using a method other than buy and try.
Even within brands the cards may be different, just because one bloke gets it working doesnt mean you will with yours. I have 2 2GB Sandisk class4 bought on the same day at the same store, identical, one works one doesnt, i hve a 4GB Kingston that wont but the 8GB does.
Its a bit of a lottery im affraid, im sure folk will disagree but from my point of view i wouldnt go spend a fortune on a card that maybe useless, if you dont mind burning money or have another use for it then get whatever but just edge on the side of caution!
try re-formatting your sd card, if problem still happens then it's your sd card and you need a new one.

You're completely right... there's no guarantee that any particular sd card will work. Manufacturers don't rate the random access speed and they don't keep it consistent. One batch of the same may work while another batch made the next day may not work. Sandisk class 2 and 4 seem to most consistently work... no kingston has worked well for me yet, but 7/8 of the sandisk class 2 and 4 cards I've tried has... the one sandisk card that didn't work well was a 16gb class 2, but I have another 16gb class 2 sandisk with same model number that works great.
i cant find it just now, but there is a list somwhere of all the different types of cards over several brands that some chap managed to get, stacks of data for each card, and its shocking what the companies get up to, it "appears" in somecases, main stream branded cards may infact be cheap rip offs, im not talking dodgy Ebay sales here im talking propper branded cards may infact be rebranded tat. for that reason im happy with the card i have, its slightly smaller than i would like but i dont have another use for a large card so im buggered if im going to folk out for a tiny wee paper weight if it doesnt work.

Guys,
Maybe it will be helpfull for smbd as well. I have a Sandisk 2GB card (which was included when I buy the phone) and it was incompatible several times I flashed Windows Phone 7. But when I formatted it with FAT system (not FAT32), looks like this helped - using now several days without any restarts
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?
SD Cards
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...

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...
