4gb sd card?

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.

I found one on eBay for £96.00 + £4.00 p&p.
150X 8GB OEM SAMSUNG SECURE DIGITAL SD CARD 8 GB G NEW
Looks good.

Gonna test that on Universalinux too?

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.

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.

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.

150X 4GB OEM SAMSUNG SD Card - not 150x ?

Hello everyone,
I am looking for someone who bought this card as well.
It is a Samsung OEM 4GB card, which is supposed to be 150x
Unfortunately all I can get from it is:
2MB/s write speed
8-9MB/s read speed
I tried 3 different memory readers to be sure I am not limited by them for some reason.
150x about 22-25MB/s is far away from what this card can perform
I’ve found some other guy doing similar tests.
http://www.thedvdforums.com/forums/showthread.php?t=455418
He’s results are very low comparing to advertised specs.
eBay seller mr. fastmemoryman is strongly stating that it is 150x and they tested it, however he does not explain how he managed to obtain that results.
He insists on sending in back as it is broken in his opinion. Doing so will make no difference as I bought from him as well 8GB version of that card. This time from USA, and not UK. After I did it I read it is not supported in Universal as it is SDHC
So 2 different cards, 3 different card readers …. Still no results even near 150x.
Btw. Can you post guys post your results. Just copy some big files to and from memory card. Preferably write to and then copy to different location as it might be cached in ram and that would false results.
I am gathering evidence to report him to ebay. They might be some cheap fakes or he might be just misleading people with specs.
Cheers to everyone from this forum, it helped me a lot in my early days of having Universal.

Transcend 4Gb 150x
Hiya,
Just wanted to say off the subject, I've just bought a Transcend 4Gb 150x and it's performing really well on my XDA Exec. Just thought if you don't have any luck with your Samsung, it's a viable alternative...
Best of luck with your tests!

Come on guys, could you please post some results from cards you bought?

I believe there is a lot of discussion about SD Cards on the Universal Accessories. Maybe others don't want to respond to a repetitive question.

I am looking for soemone with 150x Samsung OEM, which you can buy on ebay to verify my results.
I did use search button and checked few threads, but did not find any with many results.
I am just wondering which 4B SD 1.1 not 2.0 would have write speed of 5-10MB/s and not 2MB/s like the one I have.

oh dear, i also ordered an 8GB samsung 150x from fastmemoryman and like you it too is being sent from the US. How long did delivery take for your card? Soon as I receive mine, i will post some results as vista does show the actual transfer rate from PC > SD Card.

Ordered 21st of Jan and got it yesterday much more than 15 days.
8GB is about 4MB/s write speed and 4GB is 2MB/s .... but not 15 like advertised hehe.

4GB SD OEM from Fastmemoryman not 150X
I've had exact te same experience (same card from Ebay, same - slower - speed and same reaction from mr 'Fast'memoryman), and decided to let it be. At the time I bought it, it was cheap and I can live with this speed.

First SDXC card unveiled. Anybody working on a driver?

So, it looks like there's already a SDXC card. It's 32GB and read/write speed can hit 50MB/s. Not too shabby. Anyway, I was just wondering if anybody knows about any work being done on a driver for this; either by HTC or a third party.

I'm sure there is work being done, but not for any devices currently in existence. SDXC is not compatible with SD/SDHC devices.
Current expectations are for SDXC devices to begin hitting the market around the first of the year, according to CNET.
Which, of course, is a vast conspiracy aimed directly at me, since I was planning to get a Touch Pro 2 just about that time of year, and within 6 months HTC will come out with an SDXC-capable device.

doies this mean the 32 gb sdhc has been cancelled
i heard the 32 gb sd would be a hc not a xc

FYI, 32GB SDHC cards are already in existance, however, I am guessing that you mean 32GB microSDHC cards. In that case...
If you recall, 4GB preSDHC cards never got made by major manufacturers when the SDHC spec came out (even though 4GB was the theoretical preSDHC max). However, small manufacturers did make the 4GB cards and they were easily obtainable on eBay. I infact have a 4GB miniSD from back them.
I would guess that even if the major manufacturers do the same, that is skip over 32GBmicroSDHC cards, the gap will be filled by smaller manufactuers looking to make a buck.

no ui was just wondering
id heard report on a 32 and 128 gb micro sdhc cards
i was wondering if the sdxc was taking over this

32GB has always been proclaimed as the theoretical limit to SDHC, as I understand it - in the sense that it might be possible to create that much storage on one, but no had done it yet, so it's not proven. However, more than 32GB is not possible with the SDHC standard, so if you heard reports of 128, it was likely referring to SDXC.
I image that once SDXC hits the market, SDHC probably won't have much more than 4 or 5 years of practical life left in it as device makers migrate exclusively to the more advanced technology - rather like you don't see many floppy drives anymore.

Samsung MicroSD Cards...can anybody help me compare them?

So, as most of you already got the idea, I want to buy a SD card.
But I don't understand the difference between EVO+ and PRO+ and, the new one, Pro Endurance. It seems that the 128/256GB version of PRO+ is out of stock and Pro Endurance offers 128GB version, but it's weaker than PRO+.
If I'm giving the money, I'm interesting in spending in the best version, even though it's more expensive. In this case, EVO+ takes the trophy since it's available in 256GB.
Any other opinions on this? Thanks!

The Pro+ is supposedly the professional grade SD card. As for what folks think are the best, it's one of those subjective things and you'll probably get different opinions. For reliability the only choice for me is SanDisk. Over the years they have been proven to be the top brand of SD cards. Maybe that's why they are the most counterfeited SD card by far. Many phone manufacturers use SanDisk as their internal memory in phones and tablets. I'm partial to the SanDisk Extreme PLUS microSDXC as it supports 4K also.

I am waiting for 512GB by Samsung or SanDisk. And what about Samsung Select? Are those cherry picked for speed, reliability or both?
