[Q] SD card help for running Android? Special File System/Format/Type?

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.

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.

The SD card support (Updated: Answer from Motorola support)

My original question:
Anyone know how is this SD card support on Xoom?
I meant, is it micro SD card, mini or full size?
Is there any hardware slot?
Or is it via USB port?
I don't recall there is hardware slot there to insert SD card when I saw all those "hands on".
Answer from Motorola support can be seen from my update here:

All legit androids use microSD, as does the XOOM.
I don't know what you mean by hardware slot.
USB Port? Are you asking how the microSD slot interfaces with the device? Your question is good, because I too have been wondering where the SD Card goes.

I am not seeing any mention of SD card slot in the specs or in the user manual. Am I missing it somewhere?

I saw it in a video but it was not the same model. It had a different color for the back. But it is odd that on Best Buy site the specs show NO for sd slot and no mention of it on Motorola site or user manual. Not sure why this is a big secret since it is a big deal and in fact, deal breaker for me if it is not there.

I think I remember hearing somewhere around CES that the SD card slot didn't work and was going to be activated by a later patch. What's up with the Xoom being shipped with all kinds of missing functionality?

The BGR hands-on with the Xoom this week mentions the microSD slot is on the top of the device, along with the headphone jack and SIM slot (if applicable). There is a microSD slot on the device. It's been mentioned several times that it will require a software update from Moto to activate it - it's not clear whether that's a Google issue or a Motorola issue. There has been some speculation that it was because Android 3.0 didn't yet support SD cards at the time the Xoom was being demo'd.

Perhaps that is why it is not mentioned in any of the official specs. Pretty lame for a $800 device. So I wonder if the slot is there, when it will actually work? Very sloppy.

on page 10 of the manual theres a reference to microsd card. as for where it is i remember seeing it on the top of the xoom during hands on videos.

Thanks, I missed that:
"Tips & tricks
• Photos and videos are stored on your micro SD
memory card."
I just hope it actually works without waiting for an update. It is odd that Best Buy specs for the device do not mention an SD slot even exists.

Yes. Support WILL come. I would love to know how they are having trouble with something so basic. Based on the Viewsonic G-Tablet labeling internal memory as SD 1 and the SD card as SD 2.. perhaps they are working on a more fluid integration of it. As long as they let me put the 50,000 apps I plan to install on the internal memory similar to App2SD I'm happy for now.

I'm not bashing the iPad, but do the expensive iPad WiFi+3G versions support microSD? No, they don't. MicroSD support will come, likely shortly after launch, and 32GB of storage will be enough to tide people over until it does. I'm not worried about it.

I don't understand this comparison. If Apple had a MicroSD card on the device, it would most definitely work out of the box.

An interesting point. iPad doesn't have the functionality at all and never will based on current devices. You have to decide how much space you want at release, which I find annoying as I always bought the cheapest device.

On one hand, I agree, Apple never releases a device unfinished. On the other hand, they accomplish this by taking a long time for a device to come to market, and they are always behind in both specs and features.
Apple has proven the merit of a wholly controlled ecosystem that lends to a more solid device. Many people don't care about specs and advanced features.

Apple does take their time and won't rush to just release a product.
I am sure motorola will have a patch ready to go soon if not already. they may have already gotten it done and put on the device.

Being an early adopter of gadgets I understand that sometimes the first release can be a little buggy.
However it bugs me that Motorola did not clarify these issues. No flash and no SD support out of the gate is something that should have been clarified to everyone. I have followed pretty closely the last month and did not realize either of these issues until today.
Having the promise of working features after day 1 is not always a lock as my Galaxy S phone was promised to have an update for flash support and an update to fix the GPS issue yet that has never happened.
i am still buying one on Thursday but will be deciding on the 29th day if I feel I can trust Motorola.

MOTO just wanted to wear the hat of "first to market a honeycomb tablet". Its a race for that hat, with solid patches coming down the pipe pretty quickly.

So, apparently, this could be something NEW to Android.
There is only 1 single partition for all apps, media, files, etc.
That's good!

I think I talked about this in a different thread, but the reason for the delay in sd card support is because the sd card will not be mounted/unmounted whenever you plug it into the pc. Which I would prefer. Having my sd card mount and unmount every time I plug it into the pc is annoying.
This is the reason for the delay. Rebuilding the wheel takes some time.

Mango SD Card Compatibility Research

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.

Sandisk 64Gb microSDXC : have anyone tryed already?

Guys, newest sandisk 64gb microSDXC will fit Defy?
http://www.sandisk.com/products/mobile1-memory-products/sandisk-ultra-microsdxc-card

It will fit in nicely becuse it is the same size as the microSDHC.
It doesnt work out of box ;you have to format it in the phone..then you' ll get 59 GB of free space.
No, i dont have it but i have read about it and it works in htc,samsung..

According to specs, memory is upgrade-able only to 32gb.
Will a 64gb card work?

I think you should take the risk and test it yourself

So does it work? That´s a very nice sd card

the defy supports 32gb sd official. 64 gb not supported. I think for any phone 16gb is stable for space and speed. how do they fill up 32gb?!

There are also reports that they are working on many older devices for those wondering. Some include the EVO 4G, original Galaxy S, and even the HTC Desire Z (aka T-Mobile G2). With both old and new, smartphones and tablets being able to take advantage of the 64GB SD cards this is a good sign many more will have the same fate. We can only assume manufacturers didn’t state SDXC support because none were out on the market at time of launch, or maybe there are other reasons yet unknown.
At first insert the device may say corrupt or error, just reformat your 64GB card inside the Android phone or tablet and you’re good to go. While many are currently working, this doesn’t mean they have full support. The chance of the cards failing, getting errors, and possibly losing all your stored data is still a possibility so use at your own risk for now. Hopefully we see more 64GB SDXC cards soon and at lower prices because $219 is a bit steep for me. — Thanks Murray!

SDXC cards use exfat file system. If defy doesnt support that then it probably wont work.
Ive seen reports of it being working on a lot of phones, so there's a chance it might work on defy, but the card needs to be formatted on pc first before using on phone and it wont work at full speed due to limitation on the old sdhc reader (sdxc reader is faster)

I'm asking to avoid risks ).
Why 64gb? Cause i have 32gb card and it have about 4gb left. Actually last few month i've forced to clean up card from time to time. Audiobooks, DVR, Navigation software, record lections on dictaphone... That stuff takes space but i've used not to worry about `if do i have avaliable space left` ). Also this card declares class 6, now i own Sandisk/32gb class 2, so it not just larger, it laso should be faster. Sometimes DVR+Navigation provides some lags, for example.

maybe the max is 32GB,class 10

you can buy but i thin you will see only 32gb space...

can defy uses class 10 sd card? i heard there is problem in taking picture with class 10 card...

read posts on XDA, yes it has a problem with 6 and 10 class

CM7 and miui can run fine class 10 cards now.

http://forum.xda-developers.com/showthread.php?t=1133548&highlight=class+10

SDXC on Defy?
It really works on Defy. I own one for a month now. Cost 80€/106$. Absolutely no problems after format. 59GB free. About 6MB/s write, 16MB/s read speed. Have fun.

Greater than 32Gb?
Biggest I've used is a 32Gb class 10. No problems at all.

Android police posted a review. Looks good.

This is funny yet strange. Why you think an article on a website has more truth than a forum post of a member? Both are written by a single person. Both can be faked or real.
The guy on the website used a newer Tegra device so his article is irrelevant for Defy users. The SDXC in my Defy works flawlessly for weeks now with 20GB free space left.
Of course you can ignore this. I don't care. But if you need space buy the SDXC and have fun.
