Hi guys
i love my himalaya and for christmas i want to treat it to a nice big sd card.
now i know under wm2005 people have been getting 4gig cards and 8gig cards... but from what i hear the older versions of windows have more difficulty with these sizes.. i'm currently using plain old ppc2003 for my backpack/wireless stuff what size can i get with the older windows eg 2003/2003se...any recommendations on cards...i know some are less friendly than others
SD
i am using 1gig Transcend SD sard, have tried putting in 2gig SD card from my friend, works fine.
Hi guys,
Lately ive been trying to get Android running on my HD2…
Ive successfully flashed the HD2 to android friendly ROMs, and installed versions of Android to my SD card… but I cannot get it to run.
I have read some things about needing a certain SD (file system, or a certain type of card/partion size?)… can someone please tell me if my SD card is android compatible… if I can just format it or if I need another card?
The SD card I have is a SanDisk 16GB MicroSDHC. I thought I heard something about needing a “Level/Class 4” or something, but I don’t know what that means.
I hope this question makes enough sense, and someone can break it down for me.
Any help is greatly appreciated.
Cheers.

your sd card is fine. I've ran many android builds off that microSD, which if I'm assuming correctly is the one that comes with the HD2. Do a full format, not quick (so uncheck that box in windows). The preferred allocation size is 32k. If that doesn't work try formatting with SDFormatter
Thanks for your reply mate.
It is the SD card that came with my HD2, but I have the Telstra Version (T9193), so im not sure if it shipped with the same SD card world-wide.
I have just done some more research on the Class/Level Numbers of these SD cards, and I think the Class/Level Number is marked on the card with a circle around it, if that’s the case I have a Class/Level 2 card.
Thanks again for your reply, hopefully once I format the card, I will have more success than I had previously had.
Cheers.
one more thing though... what filesystem should i format the card to?
cheers.

FAT32, always
Edit: Yes, SanDisk class 2 is the same card mine came with. I've heard of some people getting them with 2GB cards, but I think for the most part 16GB calss 2 are what most people got.
no problem, thank you for your help.
it says right on the box it comes with a 16gb sd card.. if yours came with something else then the rep or the store owner took the 16gb card out and replaced it.
some shady stores would do this and try to sell you the card it came with.

i have no doubt the card i have is the card i was supposed to receive, i just wasnt sure if it was compatible with android.
cheers man.

Tmous got 16gb cards. Euro got 2gb ones.
Corrections, and swift answer
Firstly, flash storage devices marked as class 2 or class 4 would have nothing to do with comptibilty. Flash storage classes are the specifications of the maximum theoretical limit transfer speeds for that type of flash storage device. Take a look at this wiki article to learn more at wiki secure digital class rating article. Next, the type of storage device needs to be specified as microSD rather than SD since they are different flash types. And lastly the proper terms for storage sizes need to be used. GB means Gigabyte which is 1x10^9 bytes or 8x10^9 bits as 8 bits=1 byte, and Gb is Gigabit. The problem doesn't lie in the syntax or intended use of, it lies in the dumbing down, so should someone be wanting to learn these things they are getting taught wrong.
And for the swift answer, no class never makes a difference on compatiblity just whether it has the suffix HC or not, which stands for High Capacity as is reserved for any storage amount of 4GB to 32GB in which case is goes to XC which stands for extreme capactity and is reserved for 64GB to 2TB(TB=terabytes). The only reason this matters is each type of suffix is actually signifying a new type of transfer protocol which requires a firmware upgrade to read the new format(key work firmware not hardware, as one example even the oldest SD card reader could read a 128GB card with a proper firmware upgrade, albiet at lower transfer rates). And the format fat32 is typically used as the standard external storage filesystem.
I hope this answers any and all questions, always remember, what your writing doesn't just apply to you and your not the only one involved. Your words reflect like a butterflies wings.

Whilst your knowledge is great, the fact that you're unnecessarily bringing up an old thread from 2010 is not. I understand the need for 10 posts, and using your knowledge to help others in order to get 10 posts is the best way of doing it, but do it on new threads rather than old ones please.
I bought a new nook color the other day. It has 1.0.2 on it and looks like it has only 1G available in the about section.
I was able to create and SD card with CM7 (7.0.3) and boot from it just fine. However, just about any application I open force closes repeatedly. What is my best option with the newer partitioned nook to get a stable build where things work (including Ad-hoc wireless)? I've looked around and there is quite a few threads on how to do a lot of this but from what I've read (and possibly misunderstood) a lot of these are for the older partitioned nooks.
I like the idea of being able to run off an SD card and boot back to my regular nook when I want / need to. Also it appears that you can just root the regular nook OS and be able to use the market and associated apps along with it. I think for me that would be perfect. All I really want is to be able to install a few apps off the market. (who wants to pay 2.99 for Angry birds when it's free!?!?)
Considering the previous I would like some input as to what my best option would be.
OBTW - running the CM7 from an 8 GB Class 10 card if that makes a difference.
Thanks in advance.
In my experience the SD card makes a big difference. The class 10 doesn't really help you with this SD card approach. The random read/write speed is important and the class doesn't correlate with that. I would suggest getting a class 4 SANDISK 8 GB card and repeating the process. I had force closes with a class 6 Transcend 8 GB and have no problems with the SANDISK. I could be wrong, but I don't think that the partition should matter for the SD card ROMers like us. Everything runs from the card, so the internal partitions don't matter.
^ Correctomundo.
You'd probably find all your troubles gone the moment you ditch that Class 10 card and use a Sandisk Class 4/8G. Just make sure you get a genuine card from a reputable dealer. 4 in 10 Sandisk cards are fake.
I am having this issue right now. I used the most recent verygreen with one of the recent nightly builds running on an 8 gig Kingston class 4 card. I did a SD card test and got read/writes at 6mps. Would a switch to a Sandisk really cure my problems? I have a 16gb class 2 in my phone. Can I just image my 8gb with all the apps, etc on it to the 16gb card and it will start right up? Thx.
The cards that have been found to work well most consistently are Sandisk 8GB and 16GB, class 2, 4 or unclassed. There is some variation between cards of the same make and class.

That card and plan should work fine. After you write the 8GB image to the 16GB card, just extend the SDcard partition to take up the unallocated space. You could also do a Titanium Back-up to Dropbox (or just save a copy of the TB folder to your PC), write a fresh verygreen install to the 16GB, then restore through TB.
Get your Sandisk card from somewhere with a good return policy. My first Sandisk class 2 8GB was awful, awful, awful. My 2nd was silly fast.
I just wanted to share my testing with all that are upgrading to Yuki-XBmod Mango Rom.
I was experiencing many problems with Mango on my HD2 and it was all associated to my SD card (patriot 16gb C4), although it worked decently in NODO. After doing some research I came across this great thread in XDA (http://forum.xda-developers.com/showthread.php?t=1150369) and decided to test some cards out for my self to see if I can get WP7 Mango running smoothly on my phone.
So I figured out that in order for the card to perform properly in WP7 you must have good random write speeds. If not, you will experience freeze, lag, random restarts, and overall headaches with WP7.
So, I did some research and found that Best Buy is selling PNY cards that are WP7 compatible.
Then after reading the above mentioned thread, I saw that the sandisk 32gb class 4 had great random speed results, so I decided to test both and my old patriot 16gb C4 to find out which card I would ultimately use as my HD2-WP7 SD card.
Here are the results, click on PDF to see my screen shots: (note all cards were formatted prior to testing)
Patriot Card:
It is obvious that the Patriot Card's random write speeds are ridiculously low, so this card is going to be re-formatted and will replace my 2gb card on my point & shoot camera. It scored great an sequential speeds (good for cameras), but as it is essential for WP7 to have good sequential write and read speeds, this is not a good choice for WP7 Phones.
PNY Card:
This card did very well. Scoring only higher to the Sandisk in sequential and 512K write and slightly higher (almost negligible) in 4k and 4kQD32, in the 1st run.
Sandisk:
This card (in my opinion did best) scoring higher in all read speeds, lagging only in sequential write speeds and 512K yet higher in random write. Being that random clocking is of most importance to WP7, I think that Sandisk 32gb class 4 will be the SD card I choose for my WP7 Windows Phone.
______________________Conclusion__________________ ______________
Both the PNY and Sandisk cards will work great in WP7 Phones, but I chose the Sandisk because it has higher read speeds. So that means once the program or data is loaded it will be able to read it faster. The most important factor for my decision was that the PNY costs 89.99 plus tax at best buy. The sandisk runs for 69.99 and I did a price match with a Comp USA printout and purchased the card for 59.99 plus tax. (30 dollars cheaper)
I highly recommend that anyone who is planning on switching to WP7, test their cards first with Crystal disk. If your random write speed is low, do not install WP7 until you get a better card.
I have also conveniently attached Crystal Disk so that you may test your cards and post the results. Please understand that the test will not work after you have already encrypted your card with WP7.
I disagree actuallly, after testing myself, i dont believe that testing with this software can indicate the speed of the card.
I believe that there are other factors involved that we are un-ware of.
For example, my 16GB sandisk class 2 gave great randoom r/w speeds with this piece of software, but in practice, it was slow, and very buggy.
So i switcheed and bought a 8GB sandisk class 4, which in tests, was actually slower than then 16gb one, but performed perfectly, lightening fast, installing apps in under 30 seconds everytime.
This is why i dont think you can accurately depict the likelyhood of a card working based on these values alone.
You could argue that if its incredibly slow, (less than 0.1mb/s write) then there maybe be some impact on overall performance, but by that time, youve purchased the card anyway!!
Also, cards maybe the same brand, make and model, but that doesnt mean if someone buys that card, it will work for them.
Completely agree with stevemilw
Ive seen posts of people with 32GB Sandisk Class 4 cards that also do not work,
stevemilw, did you ever try using the HD2 as the card reader incase there was an unseen issue with the card reader its self?
OP, i admire your efforts in trying to make sense of this for people but the reality is that its still a guess, and until you try it there is no way of knowing if its going to work

I cannot disagree with your arguments. That is why I mentioned at the beginning of this thread that these were my results. I agree about the fact that cards under .1mb/s random write, would most definitely fail in WP7. I also agree that cards that score really well in the test might also not perform well in WP7.
But if this thread at least prevents one person from going out and buying a class 10 card and spending lots of $$, for no apparent reason; Just to find out the card doesn't work on the phone, then I believe this post contributed to a good cause.
I opened this thread so that a dialogue may be started so that people may post their results on the random write speeds and real life performance on WP7 Mango.
This way we may weed out some cards that for sure will not work on our devices and find out why based on the testing and not a random persons saying my card did not work in WP7. With this tool we can figure out why the card did not work. (too much or too little speed)
Happy Testing!!!!

Very True, I have also seen posts of people with Sandisk 32gb C4 cards say they don't work.
The reason I started this thread is to ask, Why didn't it work?
If your card did not work please do not clutter this thread with words saying so. Please show us data and testing on the card so that reader in this forum may analyze and figure out why the card didn't work.
Hopefully we can find out what type of card is required for good WP7 operation.
there is already a thead on this, which Steve an I took part in, there appeared to be some link between results, in that Random 4K reads needed to be around 600IOPS and random 4k writes needed to be around 20IOPS MIN,lower than that created issues. Unfortunately it wasnt as simple as that as some had cards with huge IOPS figures but still had dodgy performace.
The only thing that we never confirmed (hence my post) was if the card readers could have had a performace impact/
The other issue you have now is that we will be unable to test those SD cards once used with Mango 7712+
now, if you want to have an accurate test then i would suggest setting up a step by step guide to make sure that as many variables are removed as possible
That would be something akin to, a deep full format of the SD using a specific program with specfic settings, then connect it to something that we all have (the HD2 itsself in MAGLDR USB storage mode is a good start, then connect it to a USB 2 socket on a motherboard, then run the program for x number of times with specific settings, take an average, and then report.
You will need to get them to write down the full make and model number,
Getting folk to do that is going to be your biggest problem, but its a good idea if you can get the support for it, if enough people do it then perhaps something might be useful out of it, but unless you make up strick guidelines that everyone follows then the results will be meaningless.
Anybody know if the A500 is capable of using the 59.4GB formatted space on the SanDisk 64GB Mobile Ultra MicroSDXC Class 6 Memory Card?
edit: answer = Yes with setup tip provided by ojones838
I may be wrong but I'm fairly certain that it only supports up to 32gb microsd

That's strange, is there big difference between supporting 32gb and 64gb? I would have thought that when in development they would have made sure it supported the largest microsd on the market. 64gb (59) would be nice to have.
well, i googled, thanks for making me second-guess myself. here's your answer.
http://forums.androidcentral.com/acer-iconia-a500/141186-64gb-external-microsd-card.html
Yep. Others here have said that it works. It just won't work with FAT due to the limits of the FS. FAT32 or NTFS will work.
Guys,
I have used this SD card for months and it works like a champ. All I had to do was to format the SD in another device since the A500 has no provision for formatting a SD card. I formatted mine in my Galaxy S II, Epic 4G Touch(my first 64G SD Card went in this device anyway). Since then neither device has skipped a beat. The SD cards are expensive though. So be very careful taking them out of your device. ALWAYS unmount it or Eject it within file mgr before removing it. Also handle with care. More questions? Just ask...
Update: That's right! You don't have to unmount or eject it after use in the A500. As a matter of fact there's NO option to do so... But if you use it in another device you may need to unmount or eject it.
Just to add to the information given, a few weeks ago I bought from Woot a "Centon 64Gb Class 10" SDXC card (not micro...full size) for $55 and am using it happily with my A500. I use it with a Targus USB card reader and attach it to the full size USB port on the A500. The only snag which occurred originally was that I used "SD's" own application to format it and it would only format in "Ext", this turned out to be unreadable by the A500 but I resolved the problem by formatting the card in Windows as Fat32. This now works fine and given the size you can put on as many movies as you wish.
Just to add to what ojones838 said above.....Generally speaking the A500 will automatically mount external SD storage or USB storage as soon as it is plugged in (at least this is true of my ICS rom) but it's wise to "Unmount" the storage media before removing it.
Just for future reference, the hardware and software limitations for size are 32GB (FAT and SDHC) and 2TB (SDXC). Nothing in-between those.
Just picked one of these up from eBay. Thanks for pointing these out and the details on how to format and use it on the A500 !
FYI - Just ran SD Card Tester on it and it ran at 5.91MB/s Write and 9.19MB/s Read. So inline with expectations for a class 6 card.
@saeba.....Glad the card works for you, as I said above with that amount of usable space you can put as many movies (including large size blu-ray's) as you want. Certainly enough to keep me happy on my transatlantic flights!
Thanks for the info re the speed test, class 6 seemed to me about right.....have learn't to take maker's claims about speed with a grain of salt.
