T-mobile MDA/Sandisk 2GB

I want to get a 2GB Sandisk and I was wondering what is the cheapest way to get all of the 2gb to work on the tmobile mda? I heard i gotta buy a card reader or something but is this the only way? also what is the best brand 2GB/Card Reader (if i have to get a card reader)? Is 2GB the highest I can go with the MDA? thats all I hear people talking about.
Also what exactly would I need a 128mb backup card for? I already changed to the custom rom (2.17) so im j/w what its for

the cheapest way would be to put the card in your pda and transfer the data you want to it, no card reader needed, tho a card readers faster

so what exactly is the point of the card reader? I've read about some people being limited to 1gb with the 2gb miniSD cards

sorry end of my post should have read, a card reader writes faster.
think speed is the advantage

Not long ago a lot of people had trouble writing large files to an SD card via a PPC. As I recall, ActiveSync would take a dump during the write. I don't know how relevant that is anymore but I keep a card reader handy just in case. And as mentioned, it's magnitudes faster.

what exactly is faster? the transfer with a card reader? just a little confused what brand should I be goin with for both?

can anyone help with the brand for the miniSD and the card reader? Have seen people post about problems with formatting ni such

I personally use a generic 2gb card I bought off eBay for a total of $60.00 US. Similar to http://cgi.ebay.com/2GB-MiniSD-2GB-...temZ9705544950QQcategoryZ118260QQcmdZViewItem.
The reader I use I also got off eBay (it came with a 256mb MMC card I bought about a year ago for my old phone). It is basically the same as http://cgi.ebay.com/USB-2-0-SD-MMC-...94559134QQcategoryZ103409QQrdZ1QQcmdZViewItem.
Copying 1gb worth of MP3 files to the card using ActiveSync 4.1 takes about 20 minutes. Copying them using the card reader only takes about 5 minutes.
Hope that helps.

i got a sandisk one off ebay

SanDisk are a good reliable maker of memory cards and cheap. I have not had one fail on me yet. 2GB is the highest anyone makes at the moment on MiniSD. As for card readers, anything made in the last year should work as you just use an adaptor to put the MiniSD into a SD slot, if it doesn't have a MiniSD slot. Oh yes, SanDisk MiniSD cards come with the adaptor.

Has anyone focused on the SLC / MLC flash-chip layouts being used?
SLC is faster, more reliable, better compatible, lower power consumption and has longer lifetime but is more expensive. Chip mainly made by Samsung.
Mobymemory sells them in uk @ approx 60 GBP
MLC is the opposite. Chip mainly made by Toshiba. Branded as Sandisk, Kingston and others.
It is rumoured that a lot of high speeds cards are all SLC, but until now I havent found any confirmation.

Max card support?

Hello all, anyone know what the max card support for the universals sd/mmc reader is
Thanks

Hi there,
If I'm not wrong, the manual says clearly that universal can read/write SD cards up to 2GB (unless someone with a better expertise than me knows something different).
In any case, this is not completely right, many people uses 4GB cards (including me), but it seems that not all the applications can cope with them, photo camera is one of them, if I'm not wrong, it will not save the photos to the SD unless it has 2GB or less free space.
Somewhere else in this forum, someone else said that he even uses a sam..ung 8GB SD card (very expensive).
Hope this helps

Yup i use a 8GB Samsung SD Card to watch DVD's. I dont have the time to encode DVD's to avi xvid format so i just copy them directly to the 8GB card and watch them on the tcpmp player. Quite fun i believe. I am waiting for the 32GB SD Card release by samsung and sandisk.

im using the 4gb 150x sd card from mobymemory (£47) no probs! nice and quick too noticed tomtom load quicker.
also im using the newest qtek rom and the camera stores to card no probs (dont have to have 2gb used as per some other complaints)

Im getting the 4gb Transcend sd card soon.. im currently using 2gb transcend but I soon realized it still isnt enough...the bigger, the better of course

nuclear, I don't understand... how is an 8GB SD card possible??? 4GB should be the absolute max.
Does the Universal support SDHC in one of the newer ROMs or something?

Well the device will always show you 2000MB regardless of the ROM. But you can put more than 2000MB on your 8GB card and it will read all the files and you can use them. Its just that at this part the memory monitor will show your SD card in the negative section or full. All SD Card are compatible in the HTC Universal. Enjoy.
I am waiting for the 32GB SD Card by Samsung and SanDisk

Brain... does... not... compute.
Nuclear, I need more info. What card did you get? What brand? Is it SD or SDHC? How did you format it?
What's different about the Universal that makes it possible?!?

Its a SD. Samsung 150X 8GB SD Card for $200 or so. I formatted it when i insert it into the Universal. Then i hooked it up to my PC. Transfered a DVD into it. And then back into the Universal and it played the DVD!!!

Hmmm I got one of these
http://www.sandisk.com/Products/Item(1239)-SDSDPH-1024-SanDisk_Ultra_II_SD_Plus_USB_1GB.aspx
MUCH faster transfers when you put it straight in your PC. I'm thinking of getting the new 2Gb version soon

nuclear
We all want to see your super card 8GB. Please will take photographs cards on background your universal or you have no photo?
In the same way report us address where we can book the card on 32 GB or you have no internet address?

Thanks, ordering one now

iv currently got every single photo we have on our laptop of the kids (thousands) on the card. all my non vital apps, i just have handy menu, journal bar and a few others staying in the phones memory
then dumped the movies, saw3, world trade centre, happy feet and jackass2 on the card, plus tomtom uk & euro maps and still got just under a gig left

My Universal screwed up my precious 4GB SanDisk Extreme III card and my 8GB Samsung. Literally it made my 8GB to 2GB and my 4GB to 2GB. I lost 6GB of space on my 8GB card into nothing. I am contacting tech support all day and this is what they posted. THE MAX IS 2GB!!!! >>>>>.<<<<< scary ;(
http://www.sandisk.com/Compatibility/Device(8016)-i-mate-JasJar.aspx

I was going through the SD specifications, and it looks like that SD 1.1 could support up to 64GB (!!!) using 32KB clusters.
Unfortunately, this won't ever happen, since SD 2.0 flags anything above 2GB as a memory error.
8GB should be possible because FAT32 defaults to 4KB clusters, which would match. Larger capacity would need reformating to match the larger SD clusters, but technically it should be possible, IMHO.
So probably some of the Samsung OEMs do work at 8GB using SD 1.1. But I'm seeing the new auctions say SD 2.0 compatible only.
Oh well, I can live with 4GB, but I hope Windows Mobile adds support for SDHC and MMCplus.

Nuclear, the 4GB Sandisk I believe is SDHC, so it will probably screw things up. The 8GB Samsung you could probably reformat on your PC.
If you have an SDHC and an SD USB reader, use the SD one, as the SDHC one might force you down to 2 GB.
Hey, it's just my guess from reading the specs.

My SanDisk 4GB Extreme III is a SDHC? I was sure i bought a SD only. It says SD on it....
As for my 8GB my PC detects it as only 2GB. Reformatted and again only 2GB. I know another way to fix it. Partition MagiC!!! I lost 6GB in partition space. And same with the other 4GB card. Once i partition it every 2GB it will make 3 cards in 1 . Well stay tuned and i will let you know how paritioning the space helped.

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.

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.

HD2 Largest Micro SD card?

Hey guys,
Whats the largest micro sd I can place in my Leo... Currently have an 8 GB in there but am quickly filling it since having movies / music on it like no tomorrow!!
Any help would be great, thanks dudes.

You didn't find the answer anywhere on the net? In that case, they can hold a max of 128GB.

I've got a 16GB in mine and it works perfectly. I'll get a 32GB but want the price to drop before I do. They're still quite pricey.
16GB is suiting me fine. I have a seperate 8GB one for putting movies and stuff on. It just means I have to have CorePlayer installed on the device so I can switch cards and still play movies.
Edit:
Ignore the above comment by lude219. 128GB cards won't be available until next year at the earliest. 32GB is currently the largest on the market. There will be 64GB (and possibly 48GB) soon, but not yet.

Thank you johncmolyneux, I think I might wait a bit and get a 32gb just to be sure!
Thanks for your help dude.

can't find any 32gb micro sds on amazon or ebay? only normal sized SDHC cards.

Samsung expect their 32GB to be in the market by February according to their recent announcement, I expect Sandisk will want to be released for sale by then also.
Class 6 cards are available from non-Sandisk manufacturers by the way.

im guessing the will charge a ridculous amount...probs about £50 or some ****

16 Gb is the maximum today.
There is NO 32 gb on the market at this time, but expected.

is that because of hardware or software? i had an old HTC Excalibur that ran winmo 5.0 back in the day. got a 8 gig card that wouldn't read in it until i flashed it to winmo 6.5. after that, it read the card no problem. funny thing is the 'fine folks' over at T-Mobile assured me that nothing over 4GB would ever work in my phone.
so i wonder, with our devices being able to run winmo, android, different variations of linux, etc... could it be just a software problem?

The HTC HD2 can only hold up to a 32 gig 2.0 Micro SD card. Click the link for proof, notice the "Expansion" in the spec list, oh yeah this is straight from HTC.
http://www.htc.com/us/products/t-mobile-hd2#tech-specs

interesting info
so i started surfing around, looking for more info on this topic. i found a thread from another forum citing some interesting conversation regarding the same issue. to quote from page 5 of that forum...
"What the SD 4.0 specification will add is another pin to SDXC cards which will enable the higher read/write speeds. The rest of the pins will still be present and will still act exactly like they used to. So SDXC cards will always be compatible with SDHC readers, you just won't be able to read/write from them at 300mbit/s. And that's where a firmware update can't change things; no firmware update will allow the camera to use an SDXC card at its full, currently-non-existent future speed because that extra pin interface won't be present.
'But a firmware update CAN add support for exFAT, so all the other benefits of SDXC can in fact be added to our cameras through a firmware update. These benefits include higher capacities, larger maximum file size, and faster file deleting (because that's an exFAT feature, not an SDXC feature).
'It should be noted that the higher capacities have nothing to do with exFAT. FAT32 can have volumes up to 2 TB in size. The 32GB limit on SDHC cards was artificially imposed by the SD 2.0 specification, and has now been lifted with SD 3.0. However, the larger maximum file size IS a benefit of exFAT, because files used to be limited to 4 GB on FAT32."
so i gotta think this will also apply to any other device that can physically run an SDHC card.

so i started surfing around, looking for more info on this topic. i found a thread from another forum citing some interesting conversation regarding the same issue. to quote from page 5 of that forum...
"What the SD 4.0 specification will add is another pin to SDXC cards which will enable the higher read/write speeds. The rest of the pins will still be present and will still act exactly like they used to. So SDXC cards will always be compatible with SDHC readers, you just won't be able to read/write from them at 300mbit/s. And that's where a firmware update can't change things; no firmware update will allow the camera to use an SDXC card at its full, currently-non-existent future speed because that extra pin interface won't be present.
'But a firmware update CAN add support for exFAT, so all the other benefits of SDXC can in fact be added to our cameras through a firmware update. These benefits include higher capacities, larger maximum file size, and faster file deleting (because that's an exFAuiT feature, not an SDXC feature).
'It should be noted that the higher capacities have nothing to do with exFAT. FAT32 can have volumes up to 2 TB in size. The 32GB limit on SDHC cards was artificially imposed by the SD 2.0 specification, and has now been lifted with SD 3.0. However, the larger maximum file size IS a benefit of exFAT, because files used to be limited to 4 GB on FAT32."
so i gotta think this will also apply to any other device that can physically run an SDHC card.

Hmmmm interesting conversation there, I read all six pages by the way. The one guy seemed to be pretty sure of himself. But from what he said if you use a SDXC card that uses extFAT in a decice that does not support extFAT. It will reformat it with Fat 32 making it a regular SDHC card without the extra advantage of the higher speeds that a SDXC reader that does support extFAT can use.

right, that's what i got out of it too. but the big bonus there is that even with the reformat, the space on that card is still accessible, be it 'just' sdhc speeds. that's ok though, cuz that's what we're used to. i'd really like some of the xda developers to take a look at this and see what they can do.
on a somewhat related note, there's a program i use on my laptop called 'macdrive' which allows me to view previously unrecognized files and partitions which windows doesn't see naturally. this allows me to tri-boot (linux, mac, and windows) and modify each of those partitions from any one of the systems.
point here, is that even if there is initially a problem reading the data on a sdxc card, it seems that problem is only with the software not hardware and therefore can be modified.
if i could program i'd start experimenting myself.

This is very true, and I am in the same boot as you. I wish I had the dev knowledge and skills to start working on something for this, or a real dev could get there hands on this and see what is possible. I guess the only true way to put this to the test is for someone to get there hands on one of these beast of a SD card (64 to 128 gig what ) and stick it in the HD2 to see what it does.

HD2 Maximum storage card capacity?

I am still deliberating wether to get the HD2. One thing that worries me is the quite limited storage capacity with the microSD card. As far as I understand the microSD (SDHC) standard only supports up to 32GB capacities. I know 32GB is quite large, but I anticipate my needs will grow.
My question is - will HD2 be able to use the 64Gb, 128GB .... cards that come out probably one year from now.
Thanks for your help

Seeing 32GB cards aren't available yet, and we've been waiting for them for like 2 years, I'm pretty sure you'll have changed your HD2 before 64GB cards are here
But to the question, no idea. That would depend on whether drivers that support the new format extension are made available.

I believe 64GB is here in couple of months. Blackberry rumours are that new devices will come with support for 64GB microsd cards.

My friend ordered 2 usb sticks 64GB - 22USD each but I haven't seen them yet (I hope he gets them). That tells me that prices are still in freefall.
Sandisk is actually developing 128GB micorsd card: http://www.physorg.com/news143893844.html
I guess the problem is not with the sheer size of the microsd (ok that is important if you have a huge music library or movies or something else that needs to be on your phone all the time), but how fast it is while copying. If you put it in your phone and connect usb, how fast is it in disk mode? 20 MB/s?

HD2 has a microSDHD slot, which supports a maximum capacity of 32GB - or will it be able to use microSDXC cards? Is's probably more than a "firmware" upgrade from SDHC to SDXC.
I agree read and write speed are very important to - has anyone done any tests on the speed of the microSD slot?
20MB/s seems optimistic...

It's microSDHC... which means a maximum of 32GB.
microSDXC cards with more than 32GB will NOT work.

Well, SD to SDHC was a firmware upgrade away for many common controllers. But I've just done a little search and it seems that it might not be the case for SDHC to SDXC indeed.

It obviously depends a lot on the card used, some will take 3MB/s while some will take 20MB/s...
It does seem that it's a bit slower than a usual card reader, around 5MB/s with my class 6 8GB Sandisk card vs ~12 in a good card reader.

does HD2 support micro SDHC 64GB card?
Hi,
Here is a real eBay link to buy 64GB Micro SDHC card.
So we can put availability-problem aside.
Is it written in Micro SDHC specification that the limit is 32GB?
I dont see any 32GB size limit for Micro SDHC.
I would like to buy 64GB Micro SdHC
Can someone please tell me whether HD2 supports 64GB Micro SDHC?
Thanks in advance
Edit: confirmed that 64GB card works and its in use over a couple of years.

Well if you do buy and try it, please tell us if it works

Just check in Google and don´t let Yourself be misled by wishful thinking: 32 GB mSD cards were announced by Sandisk in Feb 2009 and still we have to wait for shipping them by expansys or easydevices.co.uk until end of May 2010, maybe June..........
Do You really think an ebay-offer of 64GB is serious ? It is only that You BELIEVE in this offer since You badly want it ! It is like believing in a religion because You HOPE that someone else might tackle with Your problems and hopes. But there is NO such other, because it does not EXIST, as well as 64 GB mSD do not exist and will not exist for the next years.
Nobody will develop them, ´cause there will be no market for them ! When 64 GB + mSD cards can be built at a reasonable prize nobody would buy them ´cause everyone of the possible customers (esp. the people HERE = early adopters = tech freaks) will already have changed their devices 2-3 times to devices with mSDXC-standards (such as HTC HD3, HD4, HD5 .......... )
Don´t BELIEVE and HOPE, just KNOW and be REALISTIC: there will be no 64GB mSD-card .............

I just wanted to look for a bigger card than the stock 16GB, even a 32GB would do, nothing particular about 64GB, nor is looking for higher capacity card any pressing need.
I am least bothered to think so much about manufacturing trouble before looking for a higher capacity card, I dont give a damn about manufacturing trouble if any.
I just searched higher capacity card than 16GB and checked at one which happened to be 64GB.
There is no need to involve big things like hope or belief in something so unimportant or cheap as a SD card.

hello
Is there someone who really tested 64 or 128 GB SDXC, on HD2?

If i remenber well, 64gb is not possible
sent from my HD2 using XDA App

Yes, 64GB microSD works on HD2...
I've learnt to never say never...
