Some info:
SD vs. SDHC
The original SD card format is limited to 2 GB of storage. That's why the SD Card Association developed the SDHC (Secure Digital High Capacity) format, which has the potential for much higher capacities.
Although standard SD and SDHC cards look identical in size and shape, only SDHC-compatible products will be able to accept cards using the new format. This is because the original SD format uses a "Byte Addressing" scheme, while the new format adopts a "Sector Addressing" scheme.
my question:
Is universal compatible withc sdhc ?
What size supports, witch cards are working ?
more info
The fates of Secure Digital (SD) memory cards and handhelds have been linked for years.
Obviously, there is no way to put a floppy drive or CD drive in a handheld, so companies were forced to turn to smaller formats.
SD cards were an obvious solution. They are about the size of a postage stamp, while still capable of storing megabytes of data.
Over the years, these cards have steadily increased in capacity while at the same time dropping in price.
With a bit of research, it's now possible to pick up a 2 GB card for less than a 16 MB one used to sell for.
But recently the SD format has run into a bit of a snag. This has forced a change that might -- or might not -- be significant. It all depends on the device you are using.
FAT16 vs. FAT32
The original SD cards use a format called FAT16. This is a system that is only capable of dealing with 2 GB of data.
Clearly, this was workable several years ago, when an SD card physically capable of storing that much data was barely on the horizon. But it is now outdated.
That's why the SD Card Association (SDA) has put together the specifications for a new, high-capacity SD memory card.
This is called the SDHC (Secure Digital High Capacity) format, and uses the FAT32 format. In its present incarnation, SDHC has a maximum capacity of 32 GB.
Aside from formatting, there are no hardware differences between SD and SDHC cards.
Past vs. Future
As many people are aware, there are already SD cards on the market that exceed the 2 GB limit, and these people are almost certainly wondering about the need for the new SDHC format.
These people should know that these cards are formatted with FAT32, not FAT16, which means that they aren't true SD cards.
In many cases, this doesn't matter, as some companies have started adding FAT32 support to their products with SD slots. But not all of them.
This is why the SDA felt the need to come up with a new name for this new format. It is supposed to ensure than anyone who buys an SD card can be confident it will work in their SD-enabled device.
Other New SDHC Features
SDHC cards are also broken up into classes based on their minimum sustained data transfer speed.
A Class 2 card can handle 2 MB/sec., a Class 4 card can handle 4 MB/sec., a Class 6 card can handle 6 MB/sec, and so on.
This allows consumers to be sure they are buying cards that meet their needs.
Other Sub-Specifications
The new SDHC specification also offers three other SD sub-specifications: SD-Audio, SD-Video, and SD-Binding.
All of these include Digital Rights Management (DRM) functions, allowing them to carry various types of files with DRM protection.
For example, SD-Binding allows wireless carriers to bind files that have been downloaded to a specific phone, and prevent unauthorized copying to other devices or computers.

well if the only difference is fat16/fat32 they should work as Universals support fat32 (my 2gb card is formatted fat32)

So does the htc universal support 8 GB SD card? Or will it be possible through firmware upgrade? What is the largest sd card I can plug into my htc universal (helmi aku 3.5)? And wich brand should i buy?
4GB SD Cards
Hi,
just for information, I'm running a 4GB SD 150x card which my Universal recognises, shows correctly in the 'storage card' tab of the memory app. I use it for music and mapping and have no issues, yet!

Format with FAT16
If FAT is the only problem here, still there's a solution
1- Plug your SD into a card reader (or you can use wm_Storage or USB-HDD applications)
2- Go to PC --> Device Manager --> Disk Management, select your SD and try to re-partition it to 2GB based partitions with FAT16 as file system.
3- return it back to your device and report the result.

I didn't try it, but I think it will work.

Will it work on the xda IIs?
It may. A user on another forum just reported succesfully using a Tanscend 4gb card in his XV6600 even though he was told it would only support 2gb...http://www.pdaphonehome.com/forums/showthread.php?s=&threadid=61612
Have tested with 2GB SData SD card myself, works fine. Didn't have 4gb but it should work as well.
The SX66 supported SD list was created back when the highest SD card was like 512meg or 1gig, that's why the supported lists are different
hi, thanks for the replies. i see it everything should be fine using a 4gb sd card.
due to the nature of the BA, and as far as i kno all other fairly recent PDAs they will support all current and future SD cards as they don't suffer the limited memory addressing of smaller less complex devices such as normal mobile phones like nokias and digital cameras
i've read somewhere the SD card standard will theoretically go up to 16gb, lets hope they arn't too far away, and that the BA will support it.
Still hoping some random company will develop and release an SDIO USB host though. Damn the BA not having Compact Flash.

Hi guys,
I'm thinking of upgrading my 512mb SD card to 2gb, but I'm not certain that the phone (Qtek 9090) will be able to work with such a large card.
Does anyone here have a 2gb card working? Any brands/models that are known to work or fail?

2gb SDCard...
Hi!
I'm currently using a 2gb SanDisk SD Card, everything works great. Oddly enough, I cannot find a card reader to connect to my PC that can read them!?!? I'm still using 2003SE and transfer movies and MP3's to the phone by using the painful multi-hour process of Exploring via ActiveSync. Uggh! This is fixed in ActiveSync 4.1 but ONLY if you are running WM5... Just having 2003SE and 4.1 will still be totally laggy for file copy.
Enjoy!

Hi! Do you have a brand name or model number of the card reader you mentioned so I can search for it on the Internet? So far I've purchased 2 different readers and neither can speak "2gb" :shock: The one I can use for 1gb cards but not 2gb cards is Belkin F5U248 rev.2, so I know that one wont work!
Thanks in advance!
Does anyone know what speed the BA supports for its SD cards?
The transfer speed is limited by the SD card type
The transfer speed should be contained within the card specification sheet
As I understand it, the maximum transfer speed is 22.5MB per second
This is for a 133X SD card, so compare accordingly
thanks for the reply. I just wanted to make sure that there wasnt a limit on the SDIO bus on the BA.
I'm planning to buy a 2gb Sandisk, but i'm not too sure whether the ultra version will work, as the compatibility list on their website only shows the standard. So i might just get the standard one to be on the safe side.
I currently use 4Gb SD card! I had only hard time finding flash card reader for my PC, which can read such a big card
I believe PPC devices has no problem with big SD cards. At least my Mio 168 PPC with GPS (PPC 2003) understand 4G card too.
But I do not believe flash manufacturers X rating. I NEVER seen real speed more than 3 Mb/s on any type of device. My card have rating x133 (22.5Mb/s). And I have no idea on what device and how did they measure that speed?
From the 2g->4gb reports it sounds like sd card size is not so much an issue for the BA, more for the SD->USB adaptor.
I have the same awful USB activesync file transfer rates reported on this thread, despite running WM5, so it sounds like my current adaptor might need upgrading.
Anyway, thanks for helping out, and I now have a 2gb 133x SD on order for next week ;-)
The typical transfer rate is 2MBps
Quotes like 133X and 150X are NOT a multiple of this but the coefficient comparison between the read and write speed
As an example for a 2MB SD card
Uploading 2MB data takes 1 second
Reading data, for that same setup, takes 1 second
For the 133X the write speed is the same, but the read time is 0.4 seconds and for the 150X card it is 0.33 seconds
This also assumes the SD interface meets SDIO v1.01
If not then the 133X and 150X cards take the same time to read as the standard card

Hi there ottGalaen,
My card reader is made by PC Line, I think it's PC World's own brand, the Model number on the back is PCL-CR400.
Here's a link to it...

Yo, what type of SD card that you using now (Sandisk Ultra II) ?
Just so you guys know my 4GB SD card is a Transcend 150x.
Sandisk, Panasonic or ....?
I recommend Transend 150x (fast) 4gb for about £55
What is the max sd size I can put on my Jamin? Is it 4G the max size?
In theory there is not a maximum size, but until you buy a particular brand and try it, you never fully know...

Ha, I have the same and I think it's pretty good too. Don't hesitate to buy a 4GB card - the space is never enough
4gb microSD or SD
Now I use Transcend 1Gb MMCmobile and I decide to buy card with more space.
Which one 4Gb card are complitable with Qtek S200 - microSD or SD?
I want microSD because of microSD is complitable with lastest Nokia and Benq-Siemens mobile phones so it's more universal.
So, which 4Gb microSD with adapter is fully complitable with Qtek S200? Anybody test it? Or better to buy standard (full phisical size) SD?
SD is the right choice for the Prophet, but if you intend to change your phone/PPC soon you are better off with a microSD.
I myself had a 4GB SD for my Prophet but I swapped it for a Herald/P4350. Nice device but it uses microSD. That sucks
microSD so far is only available as 2GB max. If you need 4GB of space take a SD-Card if you can live with 2GB than definitly go for microSD.
It usually comes with an adapter to be used as a SD-Card.
btw 4GB is the maximum size for the Prophet.
I am always wondering about this because I use a Dopod 818 pro, and the manufacturer's website says it supports up to 1GB SD Card. So it can support a 4GB on that model? Can any verify this for me, thanks!

Yes, 4GB SD-Card can be used by Prophet devices. I for myself used it for the last ten months without a problem. anything above 4GB I cannot guaranty. I'm not sure about SDHC-Cards if they are working in those devices.
Thanks Kelvin for your info. I will try to buy a standard 4GB SD card then. One more question, do you think the speed rating of the SD card has any effect on the performance? Would getting a 150x card be better?

I checked my old SD card and it was a 133x Speed. I was pleased with it. I'm not sure if the 150x performes better/faster on the Prophet, actually not even sure about the Prophet SD slot read/write performance. But in general it won't hurt going for the 150x if the price doesn't differ much from a 133x. SO GO FOR THE 150x
Thanks for your answer. Will buy it at the weekend!
It would be faster, But not on the prophet
The prophet can't use the speed since it cannot write data on a memory card so fast, Actually, Today the only speed limit is the device itself, The cards are allways getting faster and faster and faster and...........
Hello again!
I have choise between two 4Gb cards for my Prophet:
1. Transcend 4Gb Secure Digital card [MLC, 30x] (43$)
or
2. Transcend 4Gb mini Secure Digital card SDHC miniSD (43$)
or
3. Transcend 4Gb Secure Digital card 150x (50$)
Which of them is the best for Prophet (Qtek S200)?
My choise - 2nd or 3rd card (prefer 2nd because more universal) but I would like to read people's opinion. Can i feel real difference between this cards onn Prophet?

Not sure if Prophet can cope with SDHC technology, probably not.
So, 4GB SD Card will recognize in my Dopod 818 Pro with still original WM5 shipped ROM?
I tried a 4gb SDHC card with my prophet today, it didn't work. I wonder if there's a patch for sdhc support.
From PRETEC, here:-

wonder if it will work in a prophet (JAMin)
RE
If your PDA do not have a SDHC slot then PRETEC card is not backward compatible

"SDHC cards are recognized by new SDHC host devices differently than standard SD cards and are not backward compatible with legacy SD format host devices. "
Bad luck!!
What IS SDHC compatible?
I was gonna ask that one, so i will ask it anyway!
What is SDHC?
Never mind, i found this information:
http://www.sandisk.com/Assets/File/pdf/retail/SDHC1.pdf#search="sdhc compatible"
But now we need to know whether our Universal is SDHC compatible or not. Has anyone managed to find out if these new cards work with our PDA's?
Maximum capacity for this device: May support up to 2GB
But we know that's already true. So...
This quote is right from the article linked to by the first post here...
The maximum capacity of SD card is 2GB under SD 1.1 of Secure Digital Alliance (SDA) specification; however, by using file format of FAT32, many SD 1.1 host devices can use a 4GB SD card. SD 1.0/1.1 uses traditional "Byte Addressing" scheme which limits the maximum capacity to 4GB while SD 2.0 adopts "Sector Addressing" scheme which can reach the maximum capacity of 2TB (2048GB).

In other words, they 'cheat' to get the Universal and other SD 1.1 devices to see 4G, but that won't work with the 8G cards.
Brett
Would the Universal still not work with an 8GB SD card if that card was partitioned into 2x 4GB's? It certainly would be helpful if someone could try this? You just never know!
re
I guess no one will know for sure until someone tries it. BTW how do you partition a SD card anyways? Do you really think that could work?
hello
if SD 2.0 is the later version then would not all new 4 GB SD cards support "sector addressing" which would limit the ma. capacity to 2 GB
I have a 4gb that works in uni
I keep reading that people aren't able to use anything above a 2gb SD but I have been using a 4gb that I purchased on eBay for pver 6 months now. I used in with the original Jasjar ROM and also with JWrite's, Indra, and currently Helmi's. (not with the WM6's yet though)
It is interesting to note however that it won't work in any of my desktop or laptop systems without the included dongle. Not even the built in SD slot in my TC1100 tablet.
It says it's made by a company called "TopRam" if that helps anyone.
I also purchased an 8gb that SUPPOSEDLY supports SD 1.1 and 2.0 according to the documentation. It took a great deal of hunting to find one that didn't say it was HC and I'm still skeptical as to whether or not it will actually work, but as soon as it comes in and I have a chance to try it I will post the results here if anyone is interested.
I know there are one or two people here who make claims of such things, but if there are any doubters I will take some screenshots of the storage card memory screen if I need to.
SDHC uses a different software for the controller. The hardware is exactly the same. The point I'm trying to make, is that the SD people went to very radical lengths to ensure that there is no compatibility betweens SD and SDHC. They also have two different kinds of memory addressing. Bottom line, you can't use SDHC. Your device must say SDHC, and AFAIK, no PDA is SDHC compatible. With all of that said, I'm a Scoter owner, and we have valid reports of being able to access SDHC cards from a PC, through my device. It may be possible to create drivers for the SD controller, or create some kind of emulator, but that is a long way off. I've seen similar threads about those asking about 4 GB and 8 GB. Unfortunetly most don't understand the difference between SD and SDHC. SD is capable of 4 GB. SDHC starts at 2 GB and has potential in the terrabyte range. In addition, many of the real cheap 4 GB SD cards don't strictly adhere to SD standards, and may work on some reader designs, and not on others. A perfect example is that I bought a 4 GB SD card, that only works on one card reader, but not my PC reader or PDA.

Jason
SDHC Patch
I just read on a forum for Palm Treo that they have a working patch for the Treo which forms compatibility of SDHC on the Treo.
Now perhaps we can take a lesson from them and see what changes where needed to make it work. Besides, you can't tell me that there are more people working of patches for the PalmOS than WM.
well , the sdhc 8gb does not work on my xda exec-universal. so I just bought a 4gbcard "MyMemory 4GB 133X SD" from ebay that is stated as being compatible 21.94 pounds.
I'll just use my sdhc 8gb as an expensive mem stick in my sweex sdhc reader .
got it
So I received my 8gb (supposedly NON SDHC) and as expected, it won't read in my Jasjar. I am going to try and reformat it into 2 or 4gb partitions to see if that will work but I am going guess and say no. It is already in fat32 but it doesn't recognize the card at all in the PDA. Just to make sure it was in fact a full 8gb (7.6gb actually) I copied a handfull of movies (7gb) to it and then ran them on another laptop and it is in fact a good card.
I can't repartition it in XP since it sees it as a removable disk, so as soon as I get my Linux laptop back up and running, I will repartition it there and see what happens. I don't expect much though.

Could you, please, try AKU 3.5 ROM (Helmi 1.3.1 or Ivan B2)?
Because this ROM comes from device which support SDHC.
There were reports also, that Triniti with last Dopod ROM (AKU 3.5)
support Mini SDHC 4GB (maximum for mini SD now).
BTW tell us which ROM you are tryinng.
why not
If someone will send me the link to the rom files, I'll be glad to. I just don't have a lot of time right now to search the ftp site.
Two questions about Helmi's 1.3.1, first, will it support my bluetooth stereo headset like the pdaviet 207 I'm using now does? and second, I don't suppose any of these new roms has the new timechange fix already applied do they? I just don't want to keep reflashing my Jasjar and still having to apply all the reg fixes etc to correct for the new timezone/dst changes.
Guess nobody was in a hurry for me to test using the other ROMs as I have had no PM's with info as to where I can find the ROMS now that they are no longer on the ftp server here.
I find my copy of Helmi's aku3.5 1.3 and tried it with the 8gb (non-sdhc) card with no luck. I assumed as much. Not quite sure where you heard that it had SDHC support but I guess it doesn't.
I had the PDAVIET 2.0.0.0.7 or whatever the latest incarnation was and that didn't work either. I now have Helmi's WM6 1.1 that I put on last night and that one also doesn't work.
I'm sure we have some developers out there who know palm and ppc hardware who can take a look at the "fix" that was created for the Treo which allows SDHC use. I can "open" the prc file but I don't know enough about what I'm looking at to be helpful.
Not sure why this fix is so slow coming. Perhaps not enough people see the need for 8gb cards. I have a 4gb but I have to continue taking off stuff in order to put anything else on because it's always full.

4GB
I bought a D-Tec 120x 4GB SD Card, had a bit of doubt as I have never heard of D-Tec.
However, I received it today, and so far it works fine! It recognises as 4GB.
To clarify this a bit more for people -
There are two types of SD cards right now:
SD (1.1)
SDHC (2.0 - HC stands for high capacity). A good primer on the changes can be found here: http://www.sandisk.com/sdhc/SDHC.pdf
Basically, what you need to know - any card that is regular 1.1 (8mb -4GB) will work in the BA. Any card that is 2.0/SDHC (4gb -32gb) will NOT work, as 2.0 is NOT backwards compatible.
The problem here, as you may notice, is that some 4GB cards are teh 1.0 version, and some are the 2.0. If you are not careful, you may buy the wrong card, and end up with something you can't use.
Now, it is possible that some SD devices can only address values smaller than 4.0GB. But, assuming the device is FULLY 1.1 compliant, a 4.0 1.1 card should work just great.
Here is an example of the differences -
This is a 1.1 card:
http://www.newegg.com/Product/Product.asp?Item=N82E16820183017
This is a 2.0 card:
