Guys, I know this has been asked before - I just cant seem to find a conclusive answer. But here goes;
Will a SDHC 4GB SD card work on my Blueangel with Helmi's BA WM2k5 AKU3.5 (v.1.4 )? Has anyone got one working?
Hi J_Hutt
I have a 4gb SD card in my BA and it works just fine.
http://en.wikipedia.org/wiki/Secure_Digital_card
Untill reading your question and the wikipedia page above, I wasn't aware that my 4gb card was an SDHC card. My card does not show an SDHC logo, but from that wikipedia article it seems all cards >2gb are SDHC (1024byte blocks as opposed to 512).
We are of course at the mercy of wikipedia here though, its information is not always perfect.
Thanks for that, tho I gather the SD"HC" cards are different to the standard SD and not all devices are compatible (same form factor, just something about transfer rate / capacity / Fat32 file system etc)
Is anyone using a SDHC card in their WM% Blueangel?
As I can understand, there are some 4GB SD - non SDHC cards. Google for TS4GSD150. Or read this: http://www.hjreggel.net/cardspeed/index.html#special-sd.html - section "SD and SDHC Card Size Overlap"
Yeah I am aware of that (non SDHC 4GB cards) Situation is that I bought a 4GB SD (not SDHC) card online and it was DOA (not just in my BA, but in readers etc)
Supplier has just emailed me offering to replace it, but do I want a SDHC at no extra cost blah blah....and I am thinking, why not if it will work.
So, again...has anyone used a SDHC in their BA?
You can get it, and if it doesn't work on BA you will have a good excuse to buy a new smartphone...

Hi thingonaspring,
which card you have (brand, model..)? I would want to buy a 4gb's card for my Q9090. What I can buy?
Thx

4Gb SDHC card doesn't work
Not that long ago, I bought a 4Gb SDHC card and not knowing about SDHC (thinking it was another marketing term) and even though it was working fine in the cheap card reader on my desk, it did not do anything in my BA.
Went back to the supplier and switched it for a regular SD card and that one has been working fine since.
SDHC cards
SDHC cards are 3d generation SD card technology,
They have some abilities,
1 to 32 gb capacity
Improved read and write speed,
Data stability,
Content encryption etc..
This technology requires hardware support which device will use, there is no software support. ( Except USB 2.0 cardreader used computers. )
Don't buy SDHC cards, there is already normal 4 gb SD card from SanDiskand kingston, and future 8 gb will coming.
Thx.

That's a bit shortsighted IMHO, 32 gb isn't all that much these days.
i found this when i was searching. If anyone found a regular 8 GB SD card please post it here, i'll be tempted to buy it for sure because it seems like thats the best way to go. Overall if you do get the BA to accept this type of card it wont be compatible in other older devices thats currenly out now. So i think buying a SDHC Card isn't a good investment right now.
But please don't let me change anyone's mind, I'm just looking for a good investment right now.

SD Card info ... from the Windows Mobile Team ...
Everything you wanted to know about SD Cards, but were afraid to ask:
http://blogs.msdn.com/windowsmobile/archive/2007/01/12/everything-you-want-to-know-about-sd.aspx
The SD Standard used by the PPC phones at present does not support larger than 2Gb by definition. However, some 4Gb SD Cards will work in the BA, but this depends solely on the block-size which is being used by the cards.
Your mileage may vary ... try before you buy, and if you do find a 4Gb or an 8Gb one which works (and gets 8Gb of storage - not overlapped!!!) then post the brand/make/model here, as I'm sure many people would love to take their music collection along - a.la.ipod style ...
I have a knockoff SanDisk 4Gb from ebay that works in my BlueAngel (wm2003SE)
I also have the Transcend 4gb 150X card that worked fine. The card itself has problems, which is why I swapped to the knockoff.
beware that some usb readers are not able to deal with 4gb SD cards (notably the Lexar 12 in 1)
If your reader is IDing the card as 900 and change MBs your reader is struggling try another.
I have had no problems with the HTC unit and the cards. The transcend was messing up the same way in the device and every reader I threw at it...
Good luck

Incorrect, I just posted about this. SDHC format can handle much more storage than 32 GB, however there are physical theoretical limits to flash memory, just like there are those for CPU's. My post

There is no incorrect comment.
SDHC is an 3 generation NandFlash technology.
Now, The limit is 32 gb at this time,
Mean of limit is Secure, stable and usable.
May be some firms reached this limit (however you know more than 32 gb I don't now) but not this time.
There is only 8 gb cards on sale and 16 and 32's are coming in 2007-8.
Why i write 1-32 gb?
Because, there is no 512 mb SDHC but well 1 gb SDHC, you may find it.
What is SDHC, why not compitable with standart SD cards.
#1) Disk write and Read functions and commands are changed, New SDHC cards can write upto 6-10 mbps to disk and 50-80 mbps Read from disk. ( I sad disk them, they have no unique name ). This differents come from his hardware structure -->> I/O Busses, Voltage levels, frequenties and other reasons.
#2) They have a chip, he manage reading and writing operations, they have no processor, may you say DCU ( Data Controlling unit, that is mine ID ).
#3) They developed with NandFlash 2.0 technology, This is third of Nano Sized Memory blocks technology. ( You may find somethings about it ).
At the and.
SDHC cards are not compitable with SD 1.0 and 1.1 platforms, not like bluetooth 1.0 and 2.0, there is no old format support. ( No one has been sad yet )
if you want to buy SDHC, be sure the compatibility.
Blueangel's SD 1.1 slots have 1.2/12 mbps speeds ( Write/Read )
"This is not maximum speed of SD 1.1 they reached 2.1/25 mbps on USB 2.0 cardreaders."
The numbers may be some wrong, but be sure they are nearly values.
And lastone.
CPU's are not simple units. And they have so much parts.
You may find somethinks like of this comments in the Internet.
Just search it.
Come on ppl buy buy buy

Just leave one flash drive and the 8GB combo for me. When your done just let us hear the reviews

Well perhaps "incorrect" was a bit harsh. It all depends on where you get your info. here lists the ultimate capacity under the new memory addressing scheme as 2 TB. Where as here the maximum size is listed as 32 GB. Now I did mention that there are physical limitations of flash memory, and may not be able to reach the 2 TB limit, but under the SDHC standard, 2 TB is supported.

This is what I had read also. I had done some little investigation into this a few months back, so I'm no stranger to searching the web, and had done so back then and once again. With that said, the second link above actually had some new info. It lists SDHC readers as being backwards compatible. Where as what I had read sometime back, was that there were legal restrictions imposed by the SD group to prevent this. Perhaps this has changed now. Well I suppose I may be defending a bad premise, because to be honest, when I had originally searched about SDHC, I didn't come across the 32 GB limit. And I suppose I could have been more specific about what I was referring to in your post.

Jason
Good but...
This is mine last post about SDHC.
32 is Maximum reached SDHC capacity at this time, 2 TB is only theorical limit.
When someone make 2 TB SDHC then you can say the upto 2 TB capacity.
May be 2 TB SDHC's will come in future, then we can talk about 2 tb.
This is an example:
Intel goes to 45 nm technology, and that give a way to 8 or more core processor and upto 3 ghz per core speed without Netburst technoloy.
"Can you say there is already 8 core processor with 24 ghz total speed?"
You sad:
"It lists SDHC readers as being backwards compatible"
1-I sad about cards, not readers.
2-I sad SD 1.0 and 1.1 slots are can not use SDHC cards, I didn't sad SDHC Cardreaders can not read SD cards.
I write somethings about SDHC, because someone can buy them, this tech useless for our PDA's, i want help people. Because
I'v got so much help here,
May we can use SDHC's in nexttimes with external adapters or converters as SD.
May be...

I wasn't correcting you when I said this, I was correcting my statement that there was no compatibility. I had read at one point that there was no backwards compatibility (for legal reasons), but it looks like they changed that. but I will say that technically there aren't any 32 GB SDHC cards either. It is just a matter of what the question is asking, what is the largest capacity in development vs. what is the largest capacity possible.

Hey guys i just bought the 8GB SDHC card and the flash drive reader/writer that comes with it.
It will take about two weeks in shipping for me so i'll keep you guys inform of the type and where i bought it from.
I'm picking one of these magnificent devices up in the next couple of days and was going to pick up the largest microSD card I could get. However, while looking for the cards, I am seeing microSD and microSDHC.
What is the difference?
Thanx.

"SDHC
8GB SDHC cards
8GB SDHC cards
An extension of the SD standard, SDHC (Secure Digital High Capacity, SD 2.0), allows capacities in excess of 2 GB. SDHC cards are often formatted with the FAT32 file system, which supports partition sizes greater than 2 GB.[11] It uses the same form factor as SD, but the SD 2.0 standard in SDHC uses a different memory addressing method (sector addressing vs byte addressing), thus theoretically reaching a maximum capacity of up to 2048GB. SDHC cards only work in SDHC compatible devices, but standard SD cards work in both SD and SDHC devices. The SDHC trademark is licensed to ensure compatibility.[12]
SDHC cards have SD Speed Class Ratings defined by the SD Association. The SD Speed Class Ratings specify the following minimum sustained write speed on to empty SDHC cards:
* Class 2: 2 MB/s
* Class 4: 4 MB/s
* Class 6: 6 MB/s
[edit] SD and SDHC compatibility issues
As of early 2007, the simultaneous availability of non-standard 4 GB SD and 4 GB SDHC cards, and incompatibilities between SD and SDHC have caused confusion among consumers buying memory devices.
SD and SDHC cards and devices have these compatibility issues :
* Devices that do not specifically support SDHC do not recognize SDHC memory cards.
* Some manufacturers have produced 4 GB SD cards that conform to neither the SD2.0/SDHC spec nor existing SD devices."
Thank u 4 your input, mattarse. Good 2 know that the Kaiser will support ANY microSDHC card. Thanx 2 that, I ordered an 8GB microSDHC I saw on techdepot.com this morning (http://www.techdepot.com/pro/product.asp?productid=5699101).
Thanx again!

Just a post to confirm that the Kaiser works perfectly with that Sandisk 8 GB micro-SDHC. I now can carry the full Tomtom Europe maps and the full Wikipedia and still have 2 GB free.
Superb choice. I have a Sandisk 8gb MicroSDHC in mine.

Any news on when the 16Gb and 32Gb microsdhc cards are coming out?

We always want (need?) more. I have my 8 GB which is never full, depends on the use of course, if you're always on the way, you want to watch films, ok your sd will be full.
Now I'll also use as mp3 player, sure I'll complain it's not enought . Hope to see 16 GB asap hehe.
(want 32GB...what I have to wait ?? )
Hi,
I've just received my TyTn II and am interested in getting a memory card for it.
It takes Micro SD but what is the max size that it/WM6 will work with?
Also, what is Micro SDHC? and can I use it?
I've seen a 2GB MicroSD card for £7.55 del. but I probably want a bigger card.
I intend using it for tomtom - photos - some games and apps and of course data file storage.
TIA

I picked up a SanDisk 8GB via Amazon for under $70 USD (minus shipping).
http://www.amazon.com/Sandisk-Micro...1?ie=UTF8&s=electronics&qid=1204123335&sr=8-1
I have a San Disk 8gig in mine and it's great.
Cheers, Paul
Thanks for the quick replies,
As you are using 8GB cards they must be MicroSDHC? AFAIK MicroSD cards that hold 4GB or greater are all MicroSDHC.
Any chance you can pop your card and see?
The 8Gb SanDisk that I ordered is MicroSDHC (a.k.a. 2.0).
The HC stands for High Capacity and it is indeed for cards above 4 GB.
The device for the memory card has to be HC capable and lucky for us, our Kaiser is
Every micro sd card also has a class (2, 4 or 6 I believe). The higher the number, the better transfer rates (and response time), but also the bigger the cost.
I currently have a 6 GB (class 4) micro SD card. I'm going to wait a while to buy a new one until cards with about 16 GB or 32 GB (or something like that) of memory come around.
I'm also running the sandisk 8gb SDHC card. Its speedy and
works flawlessly. I got it on amazon for about 80 USD
The only thing i could recommend after having a card this big
is a good card exporting program on your phone so not
limited by activesync
Thanks for the help.
The 2GB MicroSD card at £7.55 seems very good value but I'll wait for an 8GB MicroSDHC deal to come along.
Hopefully a faster variant too..
Is it possible to connect the phone to a PC and have it recognised as a large memory stick? I know some phones do and then you can just explore them like a disc drive.
I will setup activesync at home for normal installation etc. but wondered if I could access the SD card whilst in phone from the PC/USB a la memory stick whilst at work.
yes, you can access the SD card like it's a memory stick by exploring. However, the transfer rate isn't as good as a USB connection with a stick. The 8GB SanDisk comes with a USB reader so that the card can actually be used in the reader just like a stick. Fastest transfer rate I've ever gotten with my phone
I'm using an 8Gb SanDisk MicroSDHC.
Works great!
I have a 8gb and it is fine.. but if you wait until next month you can pick up a 12gb and really have some storage space.

Talk about a deal i just purchased two 8gb for $70 because they were used and only came with one adapter.
I got my 8 gb sandisk sdhc card on ebay - another place to look for a great deal. Just be careful about the track record of the seller. I love the 8 gb card, but will be looking for a 16 gb card when they come out.
i saw the 16GB ones out anyone tried if it will work with the kaiser???
I run a Kingston 8GB SDHC in mine without problems (brought it over from my SDHC enabled Orbit), which I bought for £25 about 8 months ago from mobymemory. Never had any problems with it at all.
Thinking of buying this 16GB SDHC memory card.

But I dont wanna throw away money..so..
is the TYTNII a SD (ver. 1.0, 1.1) device? (if so then it will not recognize SDHC cards (>4GB))?
Does anyone know if this works with TYTNII (pratically, not theoretically)?
Has anyone used this or the 12GB one?
Thanks
some info on it:

The problem is how to fit it in your Kaiser ?
Cause this is not a micro SDHC card
While I don't know about the SD version on the Kaiser, I can tell you it reads 8GB SDHC cards. So if your 1.0, 1.1 versions only recognize under 4GB then the Kaiser is obviously using a later version.
Not sure on what you are going to pay for that size card... you can get an 8GB for under $50 which might be a smarter move until the others come down in price.
dang thats the price of my tilt
btw our phone support up to 32gb

LOL good point, i didn't even follow the link to see that. I thought that SDHC was only micro cards...but then again I don't own any other devices that use these so i never researched them.
So, to the OP the size should work...but make sure you get a micro!
the card u posted in ur link will NOT work becase it doesnt suppot SDHC...u just simply cant put it inside ur phone...
It does Fit into the phone, what you see in the link is the exterior part of it. The smaller card is in the inside (fits underneath the one shown).

Actually, the links provided are SD cards, not Micro SD. The picture is not a Micro SD to SD converter, it's just an SD card. Micro SD to SD converters do not show the size of the card on them
So in conclusion, no, the product(s) in the links you provided will not fit in the kaiser, and therefore will not work. However here in the UK, we can expect to see 16GB Micro SDHC on the 31st May. See here

Sorry My bad then..
Anyway now that thats sorrted out, my question still stands
Memory limit
One of HTC tech support guys basically told me that if the microSDHC card says SDHC that the Kaiser (or the Tilt he was referring to seeing as I was talking to him about my phone) will support it...and I believe he mentioned up to at least 128gb memory capacity or something. One other poster in this thread mentioned 32gb...
Now for reality, at the time of my purchase of the Tilt Nov 2008, Sandisk was the first to make 8gb microSDHC (okay others announced it too), and the time from their announcement of 8gb being put on their website at $139.99 in Nov 2007 or so.....to the availability on amazon in roughly January or Feb 2008 at 139.99....to the current amazon price of roughly in the $50 range by March/April 2008.....to the realization that very few other memory manufacturers have released 8gb microSDHC cards.......makes one think that by the time any amazing company makes anything substantially bigger than 8gb, AND releases it to market at a price I'm willing to pay for.......By that time...I and probably many of us, will have bought a newer phone with proper drivers...that the limit of memory size of microSDHC for the kaiser will be a memory.
In others words, 8gb microSDHC is the largest you will find today (most likely), and the phone will handle much more than that in its product lifetime. Buy with confidence that your kaiser in April 2008 can handle any microSDHC product available in April 2008.
Hope this helped.
thanks nicely put

That sounds awesome!!! I haven't seen the 16gb ones yet. How much do they go for?
I live near a Microcenter
so the 8G Microcenter version went on sale for 34 Bucks..thats right! Now the SANDISK 8G is a little bit more expensive but they are the same class SDs. I have the Microcenter version running right now in my Tilt with only 2Gs left...I'll probably try and get the SANDISK 16G but I might even wait to see if Microcenter comes out with their own 16G which generally is cheaper than Sandisks.

I've seen them in the range of US $75-100. I paid $98 for mine -- they were the only US supplier I could find that had them in stock.
What it says on the tin.
I believe the specs say max 32, but I'd love if someone would try it and see if it can read it. I'm really curious, and I'd love to offload all music to my phone and have it all-in-one, as my ipod's DB corrupts every few weeks and it's a huge headache, and it can't intelligently export playlists and etc.
64GB SDXC card works
I purchased the SanDisk Mobile Ultra 64 GB microSD Extended Capacity (microSDXC) Class 6 - 30 MBps Read . The phone didn't recognize it when I put it in and asked me to format the card. Once I did that it works with no problem. I got 59.46GB usable space after that. The phone sees it as sdcard-ext. The SD tools app shows the speed at 6.1 MB/s write speed and 20.9 MB/s read speed.
Ditto, haven't done a speed test with it, but rocking 57 gigs of music on here with a couple gigs free.
Just picked one off of amazon, here goes nothing...
you guys are awesome, glad it can read. Buying one tomorrow.
Just got mine Saturday, works like a charm.
Tested and works for me as well. It did not recognize it as formatted when inserted initially, but once the phone formatted it, it is working fine.
So the question now is, why don't they spec it at 64 instead of 32 GB?

Anything over 32GB is SDXC.
Apparently from what I can garner, SDXC compatibility requires recognition of exFAT formatted cards. Android doesn't have exFAT support yet, and that probably is what's preventing them from branding the phone to support SDXC cards.
These are true 64gb chips, right? Not 32gb x2? I know there were some sd cards back in the day that read higher capacity but were basically two sd cards that interfaced as one.

64 GB does work but must be formatted natively first. "officially" they only support 32GB.

From Wikipedia:
Compatibility with SDHC
SDXC host devices accept all previous families of SD memory cards.[26] Conversely, SDHC host devices will accept SDXC cards that follow Version 3.0, since the interface is identical,[3] but the following issues may affect usability:
SDXC cards are pre-formatted with Microsoft's proprietary and patented exFAT file system, which the host device might not support. Since Microsoft does not publish the specifications of exFAT and its use requires a non-free license, many alternative or older operating systems do not support exFAT for technical or legal reasons. The use of exFAT on some SDXC cards may render SDXC unsuitable as a universal exchange medium, as an SDXC card that uses exFAT would not be usable in all host devices. Since the FAT32 file system supports volumes up to the SDXC's maximum theoretical capacity of 2 TB as well, a user could reformat an SDXC card to use FAT32 for greater portability between computers (see below). FAT32-formatted SDXC cards can be used in a host device built for SDHC if the host device can handle 64 GB and larger volumes.
SDHC host devices will not test the new capability bits defined for SDXC 4.0 cards. It will therefore not be able to use the new features of SDXC, such as transfer speeds above UHS104 (104 MB/s).
