Is there anyway possible to either open up the XDA and change out the SD slot or some kind of other modification to change it to work as an SD I/O I would do anything to make this work.
Probably possible..
It would probably require:
1. Enough technical insight to produce your own customized device from scratch.
2. A new customized motherboard and reconstructing the bus structure of the whole motherboard
3. Enough money to buy at least 50 XDA IIs units..
4. Building your own customized ROM for the XDA with SD I/O support.
5. Plenty of time
So, as you see; it is possible.
Is it doable? No..
difference between sd interface of
xda1 and 2 is
with xda1 they have an extre chip to control the sd interface
with xda2 it's nativ in the cpu xcale series
so it would require an sd interface chip which was 100% the same size
and 100% the same "leg" connetors
and thats just the hardware
then you had to get all the drivers for the SDIO running
and hoping that not too many of them was locked in the rom
the time and the skills
and the chargning one self for using that much spare time
would be better spend on just about everything else
workwise to buy a new pda which had SDIO
just my 2 cents
on that note, anyone have an old xda 2? or anything close with and sdio slot that they'd trade or sell?

Hi,
Newbie question, couldn't find the answer: What's the difference between a normal sd-card and a mini sd, except for size?
What's better? I've read that pple say mini sd's the future, but why?
Enlighten me.
Thanks
I have a 1 GB mini sd ( even if my qtek 2020 only accepts SD cards - i use the adaptor of course ) because all the next devices will use mini/micro SD because they are smaller.
So it is a sort of investement for the future ! don't waste your money !
I for one really don't like this mess of different standards when it comes to flash memory.
What is there, for example, that mini-SD is too big for that actually /needs/ micro-SD? Come to think of it, what devices are really too small for good old vanilla SD cards?
Sony even announced a smaller memory stick the other day, for those people that don't find Duos too damn small already. Don't even get me started on MMC, RS-MMC and so on, it's just not required, you know? The sooner SD becomes an industry standard the better.
I bought a Magician for the very fact that it takes full-size SD cards: memory is cheaper per Gb and I've got a greater range of SDIO options.

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
Quote
"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.

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.
Hi guys
I'm not a programmer by any means, nor do I know anything about developing software, so take this idea with a grain of salt.
The issue I notice from time to time with my PPC6800 is slowdown from lack of ram (or that I haven't closed the apps and they're hogging the ram). My phone only has 64mb....so this got me thinking.... Vista has a feature called Readyboost which uses any flash based USB key to act like virtual ram (or a pagefile).
SO, how feasable would it be to create software that would coule read/write off the microSD card as if it were ram? Basically a MobileReadyboost as it were.
Discuss amongst yourselves =)
PS: Forgive me if something like this already exists for our platforms...but I haven't seen it.
SD cards read and write slow...
What if deleating the extended rom partition (located in ram, right?) and using that for a pagefile instead?
most people don't seem to use the extended rom when cooking. why not just make it usefull?????!!!!!

SD cards can be slow, but there are some models that are faster. Granted they cost more and are a little harder to find, because they are aimed photo people. But yeah.
extended rom in cooked roms is generally used for extra storage anyway so it isnt like it isnt being used
"SD cards can be slow, but there are some models that are faster. Granted they cost more and are a little harder to find, because they are aimed photo people. But yeah."
problem is that today it's not just sdcards which is the bottleneck the sd interface itself on the cpu is slow too
Does the UHS (Ultra High Speed) feature of some Class 10 MicroSD Cards mounted in Galaxy S3 or Note2 phones sometimes decrease the reliability of those cards, leading to pre-mature card failure?
See related post at Android Forums.com written March, 2013 by a senior member there:
androidforums.com/5686850-post41.html
ouch!
When posting, is XDA trying to kill us newbies with those ridiculously complicated image verifications? Or is it just because i'm using a mobile phone with a (relatively) small screen? Sound verification is even worse--no visible virtual keyboard! I imagine XDA administrators releasing a pleasant sigh while turning a big knob that makes identity verification increasingly more complex as noobs ask the same questions (like these ones) for the upteenth time. Why can't noobs just suffer in peace? I know, not the correct forum. Nevermind (my 2nd post).
UHS conflict with S3 & Note2 (cont)
I'm thinking that maybe there's a tradeoff when designing UHS type MicroSD Cards between backward compatability with non-UHS capable devices (like S3, Note2) and top UHS speed (for UHS-enabled devices like S4, Note3). I'm not familiar with the electronic circuitry--i'm just tired of MicroSD Card unreliability as the industry standard. I'm imagining that in the design process, maybe the reliability of the card when in backward compatability mode (eg, when inserted into S3 or Note2 phones) is necessarily compromised in porportion to the optimization of the UHS circuit included for UHS-enabled devices (eg, for the S4 & Note3 phones). Anybody know anything about that?
Does the 32GB Class 10 MicroSD Card that Samsung recomends for the S3 and Note2 have the UHS feature? That would be a clue. That card is not in stock, hasn't been in stock for awhile at least, so i can't buy it to find out.
Also, why does Samsung not try to sell a more expensive (and thus more profitable) 64GB MicroSD Card to S3 and Note2 owners? That capacity is not in the list of recomended accessories for S3, Note2 on Samsung's website. Is it just to reduce calls to their customer service due to the fact that the default file system on 64GB MicroSD Cards (ie Microsoft ExFat) is not accessible to Android devices (like S3 & Note2) without a third party pay-for app (due to licensing restrictions)? Couldn't Samsung easily format those cards upon manufacture with a Linux file system instead? But i suppose then ur Windows or Mac desktop computer might be unable to read the card without 3rd party software or drivers...
I'm not asking Samsung to recomend the larger-capacity cards, i'm just wondering if this is somehow related to premature failure of some cards, and how it is related. I know some S3, Note2 users love their 64GB Samsung Pro, Class 10, UHS-1 MicroSD Card and it may last years. I'm not denying that some cards from various manufacturers and re-sellers are reliable, but industry average is abysmal (i suspect, don't know) and we can't just blame it all on eBay or China or a bad batch now and again from Sandisk who developed the technology. Something is amiss, maybe several things. I'm sure that if MicroSD Cards were made with the very expensive SLC technology (one bit per cell, instead of two or more bits per cell, or something like that), then reliability would increase, but by how much? I suspect that there may be some simple, cost-effective answers out there already known but not revealed for whatever reasons (it's a conspiracy), or perhaps i just need to learn more about it.
One informative and somewhat related white paper that i did read from NEC Labs is titled, "Revisiting Storage for Smartphones (Kim 2013)". U can google n read it for free, but it's a bit dry.
Please don't post ur personal experience with individual MicroSD Cards here in this thread, but if u read some interesting market analysis/statistics about this stuff, i for one would like to hear it. XDA was once a great forum, but now it's overgrown with the weeds of individual MicroSD Card reliability complaints (and the corresponding refutations: "Don jinx that card! Mine still works great! U musta lived a bad life!") (ha!). Admitedly, not all the bad cards are really bad, and of course proprietary file systems are often to blame: "Every time i move my 64GB MicroSD Card from my phone to my desktop computer or back i have to reformat the card, so instead, when i want to transfer files, i just email myself with the files attached". Ah, thas sad.
I have been writing to Samsung about these things and hope to post more info here if and when it arrives, but don't hold ur breath. I don't feel very well-informed.
Hey guys
Im looking for a mod to swap my 64gb microsd to internal memory.
Is there any way to do this?
I've tried existing mods and app but nothings happened.
Thanks for guiding me.

why don't you use folder mount? is an amazing app!
Why???
I just don't understand why anyone in their right mind would want to swap fast internal memory for slow external memory.
External memory will always be slower than internal. I have over 300 apps and half of my internal storage space. As for my 64gb sd card, I have 54 gb used in mp3 The rest is for uploading movies and photos.
No issues with app speeds and video and audio playback.
Well gooberdude, it is possible to get pretty darn quick UHS-I cards now. With a USB 3 port and adapter, mine is darn fast for like $25 off Amazon's gold box. Problem is how fast the actual slot is lol.
In some products it can actually be better to do a swap. On the old Transformer Prime (TF201) and perhaps many Tegra 3 products, the flash chips are so crappy that even a good external card and some duct tape (to keep it in) can be a performance improvement. I've not seen a Samsung device use such crappy storage but then again, I've only used Galaxy S and Galaxy Note, not their budget fair.
In regards to the OP - rooting your tablet and using FolderMount as gooberdude suggested, it is a far less involved procedure. It is best if you just want to move some stuff from internal /storage/emulated/0 (aka /data/media, /sdcard, and /storage/sdcard).
Towards a real swap, it is usually possible by modding your system to think the external is the internal and doing some appropriate partitioning/data magic wand waving. This is an involved enough process vs what the typical PC user understands how to do that I generally DO NOT RECOMMEND unless you are a developer and comfortable building Android from source, hacking the source, and flashing code. In which case, you can also use Google and find out how to do it and how Android handles mounting file systems. Hint: look at Sony and ASUS mods.
