Since all the questions in this section revolve around the same few topics, here you have a FAQ with all the basic questions about BlueAngel accessories, you might have. If you are having suggestions for more topics to cover here or improvements, please feel free to contact me via pm.
Topic 1: SD CARDS
Q: I want to buy an sd card, which one will work?
A: The BlueAngel does not accept SDHC cards. Compare your sd card to the following images:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
a) shows an example of a standard SD card, that offers full compatibility with the BlueAngel
b) shows an SDHC card, which is incompatible with the BlueAngel. When buying a new card, make sure, the SDHC logo is NOT present.
This means, that the maximum capacity, you can use with the BA, is 4GB, because 4GB cards exist both as standard SD and SDHC.
Changes to the interface of the established format have made some older devices designed for standard SD cards (up to 4GB) unable to handle newer formats such as SDHC (starting at 4GB). All SD cards have the same physical shape, which causes confusion for many consumers.
Q: But I found SDHC drivers on the forum, won't they make it work?
A: NO, it won't. While for other devices there are actual working sdhc drivers, there are none for the BA, no matter where you found them, they won't work!
Q: What do the numbers on the sd card mean?
A: The number in the circle gives you information about the sd card's speed.
There are the following classes of sd cards, giving the following writing speeds:
- Class 2: 2 MB/s
- Class 4: 4 MB/s
- Class 6: 6 MB/s
- Class 10: 10 MB/s
As you might have guessed, the higher, the better.
Q: My card does not have a class, it has a 66x (or any other x) rating, What does that mean?
A: The × rating is a unit of measurement equal to 1.2 Mbit/s. It is derived from the standard CD-ROM drive speed. See the conversion table below for details.
Q: I saw dedicated cell phone cards, some others seem to be for digital cameras, what's up with that?
OR: On the back of the packaging, there is a compatibility list of devices, but the BA is not on it. Is this a bad sign?
A: It does not matter at all. Since the BlueAngel is a smart device, it can take just about any card, that meets the size restrictions. The mobile standard was introduced, back in the day, when mobile phones could not deliver the voltage needed for standard storage cards.
Q: Should I format a new bought card?
A: Although many cards come pre-formatted, you should never start using it right away. This is for 3 reasons:
1. Recently it was uncovered, that a manufacturer (not to be named here) shipped storage cards with a virus on them.
2. There could be crap on the card, that nobody needs (just like on new external hard drives).
3. You should make sure, it is formatted correctly for the best stability. See the picture below for the optimal way to format the card:

wired and bluetooth handsfrees and pin layout of the headphone connector
reserved for future use 2
batteries
reserved for future use 3
reserved for future use 4
reserved for future use as well
please do not reply to this thread before i finish writing the faq. i might need several posts.
also, if this could be stickied and possibly closed, i'd appreciate it.
thank you, too bad we don't have a clue on electrical consumption before buying it
Actually Classes means that the speed never goes below the class number. For example my Samsung MicroSDHC 8GB Class 6 has speeds 10-11mb/s Write and ~13mb/s Read.

Class numbers are supposed to represent the minimum sustained read speads if I'm not mistaken, although on slight ocassions it is possible that the speed may drop just below it, mine did once ...

Hi Chef_Tony,
Thank you for all these explanation.
I think you could also have made mention about Panasonic SD Formater.
That is a quite good tool to format.
You can say: "Windows can do it"
My experience will answer: "Panasonic SD Formater has posibilities that Windows don't have. I have been able to rescue (the card, not the data) a card and format it again either Windows was not able to do it... Don't ask me why"
Cheers

I'd bet the newer WM6 builds will support this card tho...
Ah, is it mearly a software issue then? I assumed it was some hard coding of a hardwear chip issue.

That's odd, the one on Play.com doesn't advertise the fact it is SDHC, but the MobyMemory one does. I wonder if the play.com is one of the non-standard ones?
MicroSDHC 4Gb. TyTN's compatibility?
Could someone confirm if this microSDHC is compatible with TyTN (hermes 200)?
I read on other foruns that is not compatible (maybe with WM05...). :?
Just have to wait till they come out and someone else has acuttaly tried putting one in there device!
I just hope the hermes supports it correctly, ie doesnt kill batt life e.t.c.
Oh and its going to need to be fat32 formatted, which shouldnt make much odds.
see http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=290117868659
I will let you know whether it works when mine arrives
When it's over the 2Gb , it has to be HC. The HC makes the addressing of hight then the FAT maximum addresable of 2Gb. Some 2Gb cards are and others are not, but anything over 2Gb is High Capacity period. So you NEED to have FAT32 also on these... otherwise, if you manage to format it in FAT, it will acutally have 2Gb of space only.

Why?? I have a 4gb SD for my (gasp!!) LifeDrive that is not SDHC. Formatted with Fat32, but not SDHC. Same design, just bigger, isn't it? The question is, would my 8525 handle a >2gb microSD, not -HC?
Would be interested to see how these go so I can drop my iPod nano 4GB and use this in the car with my CK-20W A2DP Car Kit

That's pritty much my point. In normal SD cards they have found a way to make 4GB's without SDHC, somehow. There not made to the official standard of either SDHC or just plain SD though; so it's even more confusing for people!
I believe it's to do with the fact that FAT32 is not part of the SD specification but the non-SDHC 4GB cards use it anyway.
But anyway, those not so keen on buying the 4GB straight away will just have to wait and see what others report.
At the moment the fact 4GB is so much more per GB then 2GB or 1GB is putting me off, but then that's always the same with the newest.
I just got a mail from mobymemory, they're pushing back the delivery date to the 22nd of June

Is there any way of knowing if a MicroSD SDHC card is class 2, 4, 6 If it's not printed on the card itself? Just trying to make sure I don't get screwed by some shops.
This is an example of a class 2 device:

As Lancealot already told, there is ISO specification made by the SD Card Association:
SDHC Cards have to look like this:
As you can See there must be a SD(HC) Logo and the Speed Class Logo (sometimes "Class2" - or just "2")
If you buy one look that this card as those information...
SDHC Cards shouldn't look like this:
Incorrect Logo
OR
No Logo

I'm not sure about this, I asked the same question here. But the answer was:
sthoeft said:
Why do you want an Class 6 SDHC Card? For shure not for your PPC, at least I never saw a PPC witch can use the Speed of an Class 6 Card. I got an 8 GB Class 4 microSDHC and the PPC can't use the speed, the Cardinterface is too slow. With an cardreader I can copy 4GB of data (1:1 ratio of small an big files) in about 3-4 min.

I also got now a 8 GB microSDHC Class 4, and I am really impressed about the HC-SpeedClass of 4... But I also got a Adapter with this package, and when I want to copy large files e.g. wikipedia, tomtom maps, brockhaus etc. I use the adapter to gain the full speed.

TRANSCEND microSDHC class 6 with 4GB
hello everyone!
just thought, i should add this here...
my new TRANSCEND microSDHC class 6 with 4GB seems to be working just fine!
i am using THIS ROM at the moment. wondering, if there are still some ROMs out there, which dont support SDHC cards...?
another questionw ould be, how to measure the speed on the PDA?
can Total Commander do this on the PDA as well?
any benchmark tools fpr Windows Mobile?

8GB Class 4
Thanks. I got myself a 8GB class 4 and it works great on my WM6.0.
Hi
I have searched but been unable to find a definitive answer. I apologise though if it is in the forum and I did not see it. Has anyone managed to get an 8GB class 4 micro sd SDHC card, e.g. Sandisk, working with an MDA Vario II running WM5 with the SDHC upgrade installed?
TIA
Hi,
is there a patch/firmware fix to use 4 GB miniSDCard's with HTC Wizard ?
I tryed it in a "Vodafone VPA II compact" with Windows Mobile 5.
But only a 2 GB miniSDCard can be read.
Thanks
bye

The limitation will be because the 4GB card is SDHC (High capacity) whereas the 2GB card is not. AFAIK, this cannot be patched with drivers as it is a hardware limitation. (I may be wrong though...)
You don't need any patch you must buy 4GBMiniSD card (!!! no MiniSDHC !!!), its hard to find to buy ! I have one 4GBMiniSD Topram and it works well !
Both l3v5y and mrobo are correct, in their own ways. Yes, it is possible to buy a 4 gig SD chip that will work in your Wizard, and yes, if it is SDHC it will NOT work in your phone, and no, there are no software patches, and yes, it is a hardware limitation of the SD card slot. Also, it is correct that the non SDHC chips are hard to find by comparison to the standard 2 gig chips, which are being given away as breakfast cereal toys these days...

read here info about 4gb card
http://forum.xda-developers.com/showthread.php?t=297324&page=7
I understand that this is known as a hardware limitation, but what exactly in the hardware limits it...is it the SD card controller, or is it the depth of the address bus? Basically, I'm not one to be satisfied with the reason "It's just a hardware limitation" without knowing why...
Hardware means = parts included in your wizard, physical ones
Unless you plan to dismantle your Wizard to find which ones you must replace, I don't see any other explanation to sort your problem about using 4Gb card
*sigh*...
Alright...I know by hardware limitation It means the parts in there.
What I want to know is what part, and why does it limit it. Giving the reason as a "Hardware limitation" is like someone asking "Why is the sky blue?" and you going "Because it is..."
What I want to know is why the hardware limits it. We know that there is no hardware differences on the outside of the miniSD and miniSDHC cards, ie they have the same number of lines heading into the cards. What I'd guess (without any research) it would be is the SD controller on the main board only has enough address bus lines going to it to address the 2GB max of regular SD, not a single byte more. If that's the case replacing hardware won't work unless you plan to replace the main board. And while you are at it why don't you just replace the entire phone? But I'd like to know for sure - not to replace anything, as I've already explained that's more work than it's worth - but for the academics of it.
So BUY IT!!!

It's definitely a firmware issue, not a hardware issue. If you read up on the SD sites and the SD Wiki site it tells you the difference between SD and SDHC. It comes down to how you read the cards. The pinouts are the same for both cards.
http://en.wikipedia.org/wiki/Secure_Digital_card
Here's a patch that I've not tried because I don't have any SDHC cards.
http://forum.xda-developers.com/showthread.php?t=344338
In theory it should work.
Here's why:
Devices that use SD cards identify the card by requesting a 128-bit identification string from the card. For standard-capacity SD cards, 12 of the bits are used to identify the number of memory clusters (ranging from 1 to 4096) and 3 of the bits are used to identify the number of blocks per cluster (which decode to 4, 8, 16, 32, 64, 128, 256 or 512 blocks per cluster).
In older 1.x implementations the standard capacity block was exactly 512 bytes. This gives 4096 x 512 x 512 = 1 gigabyte of storage memory. A later revision of the 1.x standard allowed a 4-bit field to indicate 1024 or 2048 bytes per block instead, yielding more than 1 gigabyte of memory storage. Devices designed before this change may incorrectly identify such cards, usually by misidentifying a card with lower capacity than is the case by assuming 512 bytes per block rather than 1024 or 2048.
For the new SDHC high capacity card (2.0) implementation, 22 bits of the identification string are used to indicate the memory size in increments of 512 KBytes. Currently 16 of the 22 bits are allowed to be used, giving a maximum size of 32 GB. All SDHC 4-GB and larger cards must be 2.0 implementations. Two bits that were previously reserved and fixed at 0 are now used for identifying the type of card, 0=standard, 1=HC, 2=reserved, 3=reserved. Non-HC devices are not programmed to read this code and therefore cannot correctly read the identification of the card.
FirmWare, a? So what do You think, what we can do?

Be extremely wary about buying SD cards via eBay. Many have been burned by small sellers forging cards that say 4G on the chip, but often have much lower (like 256K) memory actual. Silkscreening is easy and cheap way to forge a higher-value card from a lower one, and since it's eBay, your only payback is to give them a bad review and report them to eBay. You're still out the $, and have a crap SD card.
Even if it's a legitimate seller, they might not know the difference between an SDHC card and a regular SD card.
As I said, be wary. Caveat Emptor.
Not G4 specific, moved > accessories.
i know for a fact that there are 4GB non-HC miniSD's out there... that will work on our wizards. otherwise, stick with a 2GB.

I purchased one of the cards shown above from TopRam. It would not read in my phone nor would it read in a reader (it just hung my system), so I requested a return/replacement. It took a while due to the long shipping, but I got the replacement a few days ago and it worked immediately! I now have my entire GPS maps and a bunch of audiobooks, music and movies on my phone, all at once! 4GB is SO much better than 2GB (especially when the stupid GPS maps take up almost all of 2GB)!
Thanks

Hmm Thanks for the infor ...
So at last we can use 4GB Simple SD in Wizard ...
I am confused about this being a hardware issue - please forgive the noob
(I would like to apologize in advance for the fact that I might hijack this thread. It is not my intent.)
I am a long time Treo 650 user.
Specs - Treo
Specs - Wizard
The Treo 650 (AFAIK) was designed for all of 1GB of non-HC memory. The replacement of a driver was all that was required for my Treo to be capable of using up to 8GBs of SDHC memory. (If you are familiar with the Treo you know that there was more than one file in the SDHC patch, but that was because apps like Memo needed to be patched as well.)
So, while I am not expecting anyone to suddenly jump up and shout "Eureka! He's right - it has been a software issue all along!" I am wondering what it is about newer hardware that ended up interfering with something older hardware could do.
I realize there may not be an easy answer to this, but as I burn through patch after patch for the wizard - each promising SDHC, and not delivering on the promise - I have to wonder if it was not either purposefully done or is a flaw in WMedition.
After reading thread after thread, after thread I cannot wrap my brain around the volume of patches for something that is thought not to work.
Since many of you in this forum have probably been down this road already is there any combination which gives the greatest chance of success, using storage which is available today?
i.e. WM6.1 + "miniSD HC Patch v2.2.cab" + "SAMSUNG 4GB MINI SDHC CARD" = Wizard + 4GB SDHC
(I am looking for an SDHC solution because I do not see much to convince me that non-HC memory over 2GB is any easier to get working than HC 2GB and up, but HC is MUCH easier to come by.)
One last thing... Is there some relationship between the SIM and storage on the Wizard? I have a bad SIM I use for testing. When I insert my working SIM in the wizard I can get my 2GB SD card working. Then I can run tests, etc. with my bad SIM in the Wizard. If I mess up and the SD card stops working I MUST reinsert my good SIM to get it working again. Then I can switch back, once more, until I screw up again. Is this the way the wizard is designed? I have also noticed that I never gotten my 2GB SD card to work unless there is a SIM in the phone. On the Treo there is no relationship between the two, whatsoever.

I'm looking to get a 16GB card and was looking at getting a class 10 for the extra speed over a class 6, with looking to run Debian eventually. Has anyone got one on this phone? Is it worth double the price? The card that comes with the phone seems to be a class 4 as was hovering around 3.5mb/s writing which would be a little slow for Debian.
Any advice would be great.
Cheers
Hi,
here just arrived a Kingston 16GB Class10. The X10 comes with a default Class2 microSD wich is quite poor in writing speed. With the Kingston, that for the moment I have only tested with HDTune benchmark, I see that reading speed does not reach any further improvement (always 17MB/s), instead writing speed is great: never less than 12MB/s (the stock microSD rarely goes over 6 - 7MB/s in sequential write).
I will make a complete report pretty soon
Thanks for the report, I think I'll get the same. Even without running apps or Debian from it, the stock card is too slow in copying files to keep it.
Cheers

Yeah, but it's buried in the phone. To access it, take off the battery cover, remove the battery, then take out the microSD card. The "class" number is written on the card itself, as a circle with a number on it.
Note, you've probably got a class 2.

gotta disagree with you on that one, my x10 from rogers came stock with a class 10 16gb
Samsung's memory cards were updated late Wednesday with large-scale production one of the world's fastest microSD cards. The new 16GB microSDHC card runs at the same UHS-1 (Ultra High Speed-1) spec normally used for the latest full-size SD cards, giving it performance that would previously have been reserved for pro memory for DSLRs and video cameras. Sequential read speeds peak at about 80MB per second, or roughly four times the 21MB of regular microSD cards.
The storage is ostensibly meant for LTE-capable smartphones and tablets, where flash memory speed could bottleneck the connection. It should nonetheless be useful for cameras that take microSD storage and support UHS-1. Samsung reached the density through a combination of its more recent 20-nanometer manufacturing process to build 64-gigabit (8GB) chip layers as well as a toggle DDR2 interface that can saturate the newly available bandwidth.
Release schedules and prices weren't given out, although mass production usually precedes a launch within a few months or less.

Do want.
Sweet!! I just picked up a 32GB microSD. If the speeds are noticeable better then I would consider purchasing
Sent from my SAMSUNG-SGH-I717 using XDA
me too kasanRio me tooooo *insert quiet yet evil laugh*
agent2702 I think they really will be much faster 20nm tech is like ssd or some ishh isn't it .. 80mb/sec is pretty nice
I honestly wouldn't need anything larger than 16 and I actually like when my gb of my card matches my phone's internal storage for a total "nice round number"
doubt I would ever record a movie bigger than that not with my phone anyways
That's great... I've seen the UHS-I technology in action on DSLRs and it's great. Makes a huge difference if fluid 720p recordings.
That said, UHS-I cards require UHS-I capable readers. Outside of DSLR cameras, very few devices have UHS-I capable readers, and such readers are rare even on PCs.
If you put in a UHS-I into a non-UHS-I capable reader, then it defaults to a lower speed. I had this discussion earlier when pursuing a Sandisk SD Card that had a UHS-I rating as a Readyboost card for my friend's netbook. Support said that since the netbook didn't have a UHS-I reader, the card speed didn't default to Class 10, but to class 6. So far, I believe this varies from card to card.
To sum this up, do we know if the Samsung Note has a UHS-I capable reader? As far as I know, this hasn't been advertised as a feature. Further, I'd surmise that since I haven't heard of people advertising software updates for their readers upgrading to UHS-I, I imagine readers need different hardware to be UHS-I capable.

I believe they are just calling them UHS class but all new tech based on the article . just stating that they are the equiv of digi cam cards speed and performance wise but for phones ..
@shoobie:
I appreciate the article, but, I'm going to attempt to clarify on what's required for UHS-I cards. Oh, sidenote, I didn't take enough time to look at the picture to note that the cards default to class 10, which is good .
Well, what they're saying is that UHS-I hasn't been effectively implemented into the microSDHC form factor yet, only the SDHC, as DSLRs and the like use SDHC cards or CF Cards (Since DSLRs often have enough room for a larger card reader, since you often lose performance and/or increase the price dramatically when you miniaturize components).
For UHS-I to work, according to the SD Part 1 Physical Layer Simplified Specification Version 3.01, it requires that both the host device and the card be UHS compliant. Summarizing off section 3.9.4... essentially in the past, host devices communicated with the SD card via 3.3 Volt signaling. UHS uses a special 1.8V signaling at a higher speed to communicate with UHS compatible cards.
Now, I'm no engineer, and I haven't gone through the document thoroughly enough, but as far as I can tell, it's not a soft update for the card reader, but a hardware update (or basically a new reader is needed) to be UHS compatible. This theory comes from the fact that I haven't seen anyone announcing card reader updates or flashes that allow their readers to now read UHS-I cards.
The real question is: Did Samsung have the foresight to equip our Galaxy Notes with UHS compatible readers?
Otherwise, they're just setting these cards up for the next generation of phones that will definitely be UHS compatible.
Not trying to be a party pooper, just saying >,>

Someone here says that Samsung told them the Galaxy Note *does* support the UHS-1 microSD cards with their higher speeds.

Hope you don't mind my skepticism, but... after reading the post... it reads that "Samsung finally gsve me an answer, it is compatible. "... which doesn't really mean much. UHS-1 cards are compatible in older SD card readers, but said readers do not utilize the new higher speeds for the UHS-1 speed class.
Though, who knows, Samsung might... I'll try to contact them soon, though uh, who knows when I'll get a reply, anyone else want to give it a shot?
Remember, you don't want to ask if it's compatible, you want to ask if the reader is SD Card 3.0 compliant, and/or if it's a UHS-1 capable reader, and capable of reading UHS-1 cards are UHS-1 speeds.

My thoughts, exactly.
The guy did talk about buying such a memory card and experiencing faster speeds with it later down in the thread, though.
