SD-HC Cards - Windows Mobile Development and Hacking General

Hi, new to this forum so please be gentle! As my user name suggests I have a MDA-Compact II and have bought an 8GB SD-HC card. It works great in PC with adapter supplied, but is not recoginsed by my PDA phone. Is there a software patch/upgrade out there that will fix this? My existing 4GB SD card works fine, but it is not the HC version. If there is no upgrade, I guess I've just wasted £50! Thanks. Graham.

Hello and welcome.
It's too bad you haven't read / asked about this before buying. There are several threads on this.
For now there is no way to use SDHC on these devices.
Sorry.

Many thanks - you're my only respondee! Happily the nice people at Fast Memory Man (Ebay) have said they'll refund my purchase, so I guess I'm OK in the end - just have to rely on my trusty 4GB non SD-HC card.

XDA IIi SD Card problems - is this true?

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

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.

Is trinity 4 GB miniSD compliant?

Hello People,
I just bought a HTC P3600 and was wondering to purchase a 4gb mini-SD card.
I know that this topic has been treated already in other threads but after reading them all i am even more confused.
Is MobyMemory 4gb working fine?
Is 4gb TopRam working?
Which ROM should be installed to have 4gb working correctly (even after some time)?
If still not sure, can i be sure 100% that 2gb will always work?
Thanks for letting me know, i cant wait to order a 4gb!!

Many people are reporting serious corruption problems with 4GB miniSD cards both standard and SDHC (which are not supported according to specs).
Some people are also reporting problems with 2GB cards not being accessible when the device is turned on after stand-by, but I have been using a Sandisk 2GB miniSD card for more than 4 months now and I haven't had any problems with it at all.
There was a specific thread somewhere in this forum where people reported their experiences with several types of cards. As far as I remember the Sandisk 2GB card seemed to work fine for everybody.

Well, as I've stated in other threads, my TopRam 4gb is still working without any problems in my Trinity running the Dopod Test Rom, and now also with the 1.38 radio rom upgrade. Although the SDHC variety may well be working fine with some newer roms, at the moment a standard type card seems like a safer bet. I know some have had problems with all kinds of miniSD cards, but for every complaint how many quiet happy users might there be?

No! Don't buy that crap! If you fill the card with more than about 1.5 GB, bad things happen. Files get corrupted and the card can't be read in a normal card reader. They also refuse to answer mails when you want to return the card. Bad service.

OK, interesting, so it looks like a test&try approach.
Anybody elese in the Trinity world has ever tried TopRam without problems?
If i find at least another person who has it, then i may be so brave to buy it!...
Hi there,
the sandisk 2gb seems to work fine after what we can read in the forums - but does this include the ultra II version or just the regular 2gb-card?
THx, s.
Hi,
I also tried a 4GB from MobyMemory on my HTC-P3600 with latest french Orange SPV700 ROM.
Everything was fine until for unknown reason some directories & files started to be corrupted with weird characters. Then few days after, it definitively died becoming unreadable with any kind/ brand of reader. Formatting was not able to resuscitate it.
I get in touch with MobyMemory support and they kindly & promptly accepted to RMA it. I just get refunded few days ago.
So there are some problems with 4GB miniSD devices on the Trinity but none with MobyMemory support.

I'm using the Dopod Test Rom because people reported less problems with TomTom using this ROM. My TomTom doesn't lock up. I also have done the performance reg tweaks listed in the Wiki, this gives extra memory buffer for the system. Seriously, I have many apps installed on my TopRam card and use them daily. It has 3.2 gigabytes used with much of it being TomTom maps and ogg music files. I think that the cards may not be the problem, it could be the ROM version. Lots of people with other devices buy and use these cards all the time. I've checked other device forums.
I have a Kingston 4gb MiniSD card, after putting it in my Trinity it only has 1,9gb on it! Hope someone knows a fix or something
4GB MiniSD
It seems that whatever brand of 4GB card that is used in the Trinity it seems to lose files or becomes corrupted. It must be a phone problem.
I was using a 4GB U-Tek mini SD Card which made since the first of using a lot of problems, after a couple of days the card damaged, so I bought another 4GB mini SD Card (no-name) from a german ebayer, I use this card since 3 or 4 days with no problem!

I use a transcend 2Gb miniSd (since 2 months) and from time to time files become corrupted with weird character names, the only solution is to re-format. I also use a SanDisk 1Gb ultra II minisd and I never had problems with.
As Matterhorn said, that should be a ROM problem.
Personally I use a SPV M700:
ROM version: 1.23.73.3
Radio version: 1.29.00.01

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?

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.

Memory cards

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.

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.

4 GB Micro SD...Possible to use??

I use an 8525. Just noticed that a 4 GB Micro SD is now coming out. Before I buy one, does anyone know if it is possible to use these in the 8525, or will I need 3rd party software, or is there an update I can make??
I got a SanDisk 4Gb Micro SDHC card and it works fine in my SPV M3100 (HERM100) with Schaps 3.60a
Formatted capacity is about 3.8gb
Yes it will work as long as you are runing winmo 6. Next time do a quick google search for it (site:xda-developers.com what you are looking for goes here), this question comes up about once a month.

6 GB
I 've just seen a 6 gb micro sd card advertised. Would this work too?
6GB should work with WM6. Looks like ship date is 10/06/2007 in the US
Some cooked ROMs might not have the sdhc support cuz it wasnt cooked in, but that would be stupid and it will usually be listed in the specs of the ROMs if it is or isnt.
If there is sdhc (hc = high capacity btw) then anything above 2 gb should work.
HI Guys NEWBIE Question here...
I have a Tmobile Vario 2, Tytn, flashed to the htc tytn wm6 rom...found it here and seemed the most official so i went for that one...so my question is, does any version of wm6 support the 4gb or is it specific cooked versions? thanks
1GB
i have a 1GB card and i thought that would about do it for me but i guess not i had it full in 3 days......i will be looking for that 6GB, why not just come out and make us a 10GB card then i would be really happy :
