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...
Google search: 4GB minisd -SDHC -miniSDHC
Search engines are your friends...unlike these guys...

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.
Success
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 found this while looking for a 4gb sd to buy, and now i will just stick with the 2gb i have in fear of this same thing happening after i buy one for my 8125

It is a scam. Read the feedback. These are hacked 2GB and smaller cards that have been formatted to be 4GB, but that greatly shortens their shelf life, and in most cases they'll die within a few months, if they last that long.
How do you hack something so freakin small?
I'm not positive, but I think it says in the manual (8125) that it will only recognize up to 2GB ... Probably will change with later updates...just as the earlier PCz would only recognize so much RAM and HDD space until their CMOS was updated.
It may be a hardware limit. I'm from the DRAM side of things, so I'm not exactly certain how flash is addressed, but I do know that with DRAM, most computers are limited by the physical number of address drivers that are built into the chipset. Just looking at a Mini-SD, I'd guess that it's a serial device, so maybe it's just a matter of a firmware upgrade to change the bit size of the address data - or maybe it's something completely different and I have no idea what I'm talking about (it wouldn't be the first time!)
-d-
I've never heard of a 4GB miniSD, before this post. (I have seen 4GB SD cards advertised, could there be a confusion with that?)
If there are 4GB miniSD cards available, could someone post a link to them?
Here is a link :
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270025489570
much more expensive than 2 2GB cards though ... I'll need to wait a little bit to get a cheaper one for my (future) Wizard (I'm waiting for the one I've just bought on ebay )
beware!!! their are fake sd cards on ebay!!! Usually the cheap ones are the fake ones! :evil:
They are also on Amazon.com for $146. They claim that they have them in stock and others have mentioned that the picture of the card has been edited--the number 4 that is. I am somewhat tempted to try it if Amazon will back me.
here is a story of a ripp-off on ebay : http://pdaphonehome.com/forums/mall/76525-4gb-minisd-card.html
4g miniSD that works
I have purchased a 4G miniSD from http://www.emartbuy.co.uk/index.php.
It works. There is a small problem with access time, i.e. it takes longer to write to and access the card than the 2G did, but apart from that there are no issues.
All I did was use a card reader and copy everything from the 2G card to the 4G card, put it in the device and away it went, like nothing had changed. Except now there is twice the storage. YAY. The card is brandless and is probably a reflashed card, but I don't care because it works for me.
I have an Imate KJAM.
I have puchased on from Moby memory,
http://www.mobymemory.com/proddetail.asp?prod=miniSD_4096mb_MOBY_002
Seems to work OK in my Xda MiniS, and IQ

I would guess that if the power consumption and size are the same for a larger drive then the answer would be yes. Check the specifications of the installed drive and see if any larger drives exist with the same power consuption and size....let us know what you find...i'm interested. Also, PocketPCTechs are known for updates of this sort. You might consider e-mailing them and asking if they plan on having a HD upgrade for the Athena and letting us know what they say.
I've only found a 4gig SDHC card. If you find something larger let us know this also.

I'm sure I read somewhere that the tilt sensor for the Vueflow is built into the hard drive.... So swapping it for another drive would prevent that from working.

What I settled for trying.
I found a 16Gb CompactFlash to replace the MicroDrive. Pricey... very pricey, but want to try that. Power comsumption is slighly lower, so I might see improvement. I will try to mirror the "drives" before inserting the CompactFlash. I don't see why it wouldn't work. Access time is much faster also. Can't wait to try to run a movie on a plasma. Finally an alternative to renting movies in hotels! For those interrested in the drive: http://www.flash-memory-store.com/16gb-compact-flash.html The Qmemory drive seems the most interresting one. 24Mb/s access... not even sure the south bridge on this device can access the drive that fast.

Thanks for the info. I didn't think the Athena used Compact Flash. I'm sure if we contact Hitachi support they will provide us with information on a larger drive. Maybe PocketPC Tech's will soon offer an upgrade. I would prefer having them do it with a warranty.
Maybe they don't make a larger MicroDrive...check out the site

Hitachi isn't the problem... the problem is the darn CE-ATA interface I didn't notice. Intel is heading the new standard, and the founding member? Hitachi. So far, no other drives then Hitachi's 3K8. Well, they have 2/4/6/8 Gb in sizes, nothing else. 10Gb was suppose to exist, but never saw light. Tough luck for now. Until 20Gb transflash sees light, no expansion. Why oh why HTC didn't you choose the standard CF interface? Looks like I'm returning a 16Gb CF card. :-S

Good that HTC installed from the beginning the max available capacity, not 2/4/6 GB.
That's another way of looking at it. It's positive... true. I guess if you are ultra conscious in the design also, shaving off a few milimeters and tenth of grams is immportant also.
Why do people keep referring to Transflash? Transflash was the standard that became MicroSD, I thought - the thumbnail sized cards. MiniSD is like the SD equivalent of the 1/2 MMC cards.

Uh, yeah, and you can put a Transflash into an SD card adaptor and use it in your camera, too, if you want expensive, slow, small amounts of memory.
I'm not saying that it's impossible to use Transflash in the device, but that people saying Transflash may be confused about what card slot the device has and buy the wrong memory. Or more importantly, people reading might think it has a MicroSD slot.
I use MicroSD aka Transflash because I can put them in all my devices 9sometimes using adapters obviously). Where SD or MiniSD wouldn't fit in a Motorola phone or Blackberry with Transflash (or MicroSD for the purists *grin*)
cheers! I love my Athena the way it is. I still feel the urge to tweak it though! ;-)
Memory is so cheap these days, I just get each device a card - especially since my Nokia's MiniSD card doesn't seem to be recognised by the Mac (I haven't tried it in the Athena yet). 4GB is only £40!
That looks like a 1" drive, like wots inside some iPods. Is it even smaller than that?
Hey guys
i got my TD2 today! can i use 32GB microSD card? dose it support it?
if so, where can i buy it?

I can confirm that the 16GB card works fine, not sure about 32GB.
What would you put on the 32GB card to fill it up, lot's of movies? I have lots of apps, TomTom maps of the UK & USA, some movies & mp3's and still have plenty of room left over. Maybe in time I will look back and wish I purchased a 32GB but at the moment It's more than enough.

Even when the 32GB cards come out, they will be relatively very expensive. It would be much cheaper to buy 2 16GB cards and swap-out when wanted. After all, you can swap cards easily enough if you only use them for media and avoid putting programs and other essential data on them. There's surely enough storage on board the D2 for all the progs you could want?
Then just stick, say, music on one card and video on the other. Swapping takes 30 seconds, maybe? The other benefit is if you get a card failure it's a lot less traumatic to your wallet.
@ root beer: It's very easy to fill up 32GB, a lot of people's music collection @ 320k takes up this space. Before you even consider videos etc

Agreed, i just bought a 16GB card for my TD2, but tried it in my old Touch Dual and it works fine, I was always advised that could only take 8GB.
What is the thing that like makes a limit for how much a device can take? I mean, there must be something.
Its the limitations of SD. Any device that is SD 2.0 Complient will work with upto 32GB wheras SD1.x devices will work with cards <2GB

Any news on the 32gb Micro SD card ?
hope it wil be a class 8 or 10
If the 32GB MicroSDHC card comes out anytime soon (Which I doubt), the first ones will be class 2 or 4 at best, and cost at least half-again as much as two 16GB cards. A single 16Gb card is $50 @ microcenter.com, so I predict once the 32GB's come out, they'll be at least $150 each.

{
"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:

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

So I've ordered the Samsung micro SD card Pro plus 64GB. It's Samsungs flagship model. This card supports read speeds up to 95MB/s and write speeds up to 90MB/s. But judging by my results I'm not getting near those speeds.
A1 SD Bench:

"lightbox_next": "Next",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So what speeds are supported by the Z5C?
What cards are you guys using and what speeds are you getting with "A1 SD Bench" app?
By the power of Sony Xperia Z5 Compact
I tried today a Transcend Ultimate 64GB 633x with Up to 95MBs Read and 85MB/s write.
I got 42,91MB/s Read and 28,65MB/s Write... quiet bad in my opinion
I have the same Samsung Pro+ 64gb card and I am not getting anywhere near as advertised either. My read/write speeds are similar to yours.
Do you think this would be due to only 2gb of RAM?

Those speed have nothing to do with RAM. If I were to make an educated guess, the speed depends on the microSD-Card reader and/or the chipset.
I think it's a bit over-simplified to talk about microsdxc speeds without any further qualifications. The manufacturer-advertised speeds are only achievable under ideal conditions (sequential as opposed to random access, specific file size etc.) If the benchmark you're running is different from the one the manufacturer ran, you may measure much lower speeds.
I'm not saying I'm positive the SoC/SD card reader in the Z5C isn't the bottleneck, I'm not sure. My point is that micoSDXC cards are much slower than advertised in real-world scenarios (and realistic benchmarks), even when using them via a super-fast card reader such as a Kingston USB 3.0 FCR-HS4 and a high-endish desktop PC.

I can support dafie's scepsis. My last mircoSD class10 card from Transcend had advertised Speeds of 60mb/s read and 20mb/s write, but actually performed only about 50mb/s read (which is okay to me) and 9-11 mb/s write (which I find very lackluster). I tested this on several card readers (Xperia Z3C, Macbook Air, USB2.0-Adapter on a Windows PC).
@Mythos123 So if you want to know wether the limitation lies within the phone or the sd card I suggest you test it on an integrated sd card reader on a modern laptop or a dedicated usb 3.0 card reader at any decent pc.

Unfortunately my laptop is really old, so I can't compare speeds.
By the power of Sony Xperia Z5 Compact
This is disconcerting because if you look through the amazon-reviews you will also find benchmarks made on android which confirm the speeds that are advertised.
I'm currently using an older 128GB card with only 30MBs/10MBs and was considering an update, but i guess i'm less motivated to do so now.
Did you try with another software?
I've an old "SanDisk ULTRA 64GB" and the results (with that app) are:
Read: 36.17MB/s
Write: 12.15MB/s
I'd like a faster SD capable of write at 70MB/s+ isn't that possible in the Z5 Compact? (If I move games, like Hearthstone from Internal Memory to External Memory they are really slow).
@Mythos123
I just bought one Samsung Pro+ 32GB..
Write speed can't pass 21MB/s with that bench app.
I think we have a very slow card reader or some kind of bug. (Yours write a 36MB/s at least).
EDIT:
- I formated the 32GB SD from FAT32 to exFAT (because Android formatted it as FAT32).
- If I do this test (with this app) many times in a row (using the quick test), write speed raises up to 35-37MB/s, so I think sdcards tests don't work fine at the moment, and...37MB/s is the peak for our card reader.+
- The sequential write speed using USB cable (and USB 3.0 port just in case is above 30MB/s and supported by the Xperia) is 20MB/s approximately. (Copied a .MKV of 15700MB in 13.5 minutes).
So, in summary:
Max sequential write speed achieved with an app: 37MB/s
Max sequential write speed achieved with USB and MTP protocol: 20MB/s.
Such a pitty, Smart phones are in many ways still way way behind desktop and laptop solutions..
I suppose to really compare, you'd have to find a benchmark test on an review. Then use the exact same software and test it on the Sony. Repeating the test as closely as you can.
I've got a 64gb card now (samsung pro) also. I've been thinking about upgrading to a 128GB or 200GB. Has anyone tried getting a larger card? or are those all slower. (I want to carry a copy of all my photos around with me rather than use up precious data whenever I want to look at one)
All Z1 to Z5 limited to 40MB read/write by the card reader chip.
There's really no use for getting fastest cards. They will all be limited by the phone speed

So based on this, what's the most value for money card to get?
EDIT: I mean, I'm reading some information online about needing a UHS-I "U3" class card for 4k video recording. With a 40MB/S read/write limit, isn't it going to be impossible even if we use a "U3" card?

Sandisk Extreme microSD(mid class), no need Extreme Pro(high-end). If you want Samsung, you will still to buy EVO Pro as the entry level of EVO Plus got only 20MB/s write. Samsung and Toshiba seems no medium classes.
I previously own m4 aqua, and i have sandisk extreme
I got 42MB/s read and 36MB/s write on m4 aqua
The card is advertised as 60MB/s read and 40MB/s write speed and displays the UHS Speed Class 3 (U3) designation
I never do benchmark again after switch to z5 compact, but I think the result will be same

I'm about to go from the Samsung 64 up to 200gb. They're on sale right now for $80.write speeds never really bother me like hitting the size limit does lol

P.S. when you put 50+GB of photos on a phone, the thumbnails really slow it down. Putting them in a hidden system folder (.nameoffolder) really helps with not lagging the device and gallery/camera down!

Video recording is using Mbit while sdcard is using MByte .... 40MB/s x 8 = 320Mbit
There is no any consumer level of DSLR/phone reached [email protected] yet but a higher speed card is always help because probably it takes a shorter time to writing data and hence, reduced heat and save battery. Take a example, 200MB for a 20MB/s card spend 10s while only 5s needed for a 40MB/s card and you saved battery for that 5 seconds and generated smaller heat as well.

Modern entry level card got a much faster speed usually has 15~20MB/s write and very valuable. In the old day slow card is real slow with just 4~8MB/s writing speed.
