Has anyone had any issues running CM7 on a SanDisk Class4 microSD?
I bought one used, and got CM7 running, but with plenty of Force Close errors. After running a benchmark on the card, it sounds like I got a bad card (for running CM7, anyways).
Here are my CrystalDiskMark scores, run with the same card, in various adapters on my laptop:
SanDisk 32GB Class4
Random Write 4KB (QD=32)
Kingston USB Card Reader
0.230 MB/s [ 56.3 IOPS]
Patriot microSD Card Adapter in SD Card Slot ThinkPad L412
0.054 MB/s [ 13.2 IOPS]
SimpleTech microSD Card Adapter in SD Card Slot ThinkPad L412
0.065 MB/s [ 15.9 IOPS]
Kinda crappy compared to other results I've seen. Anyone else have bad luck? Any suggestions, other than a new card?
Thanks!
You'll always get lower scores when testing in a card adapter compared to a USB reader - but the speed you get from the reader seems a bit below normal by about half - you might've just gotten a bad card.
Is it a recent purchase? You can probably exchange it - they run off a ton of these at a time and a bad one's bound to slip through here and there.
The links to the memory card threads are in my sig if you wanna jump back into them quickly.
Where did you buy the card from? Hopefully it is defective and returnable, rather than counterfeit.

This is my suspicion.. However, C4 I'd think he bought in a Brick and Mortar vs online where it's entirely too easy to wind up with counterfeit SD cards.
Bought it from a guy on craigslist. The card seems legit, full 32GB capacity, 6MB/s seq. write speed, just crappy random write speed.
Anyone else with a SanDisk 32GB Class4 care to post CrystalDiskMark Results? I haven't found any when searching the forums... just 8GB and 16GB...
I bought a sandisk 32gb class4 from amazon. I don't recall the benchmark numbers off the top of my head, so I'll have to test it when I get home from work.
I did, however, recently move over from booting off the sdcard to booting off the emmc... It seemed to be a HUGE difference in performance. While I didn't get any FC's when running on the sdcard, the system did feel a bit laggy. Or I could just be imagining things...
Interesting. I look forward to seeing your benchmark results. Was your a standard SanDisk card, or one of those "EXTREME" cards? (do they make those in a class4?)
I've read that a lot of people like running CM7 directly from the onboard memory. I'm weary of doing that, and I also like having the standard nook software too. Maybe if there was a way to dual-boot from the eMMC, then maybe I'd try it.
Thanks in advance for your benchmark test results.
I have two different SanDisk 32gb cards and both have been working fine for me. I can't remember the benchmarks right now but I do remember them being similar but a little better than may 16 gb and 8 gb SanDisk class 4 cards.
It also didn't seem sluggish to me after overclocking it a little bit.

If you have a good card then CM7 runs fine from it and I've done quite a few onto 32G Sandisk class 4 and got nice performance. However, there are significant advantages in running from emmc. For example, you then use the SD card as a simple, single partition card containing just user / data files rather than as a multi-partition card containing both the ROM partitions and user data. Updates become easier to manage as the standard ROM Manager / clockwork methods just work as intended rather than having to put renamed update zips onto the boot partition of the SD.
I'd not be weary of it, just because it sounds like a risky one way trip. There are good ways of reverting to stock if you need to.
It is possible to dual boot Nook stock and CM7 off the emmc, and I did that successfully for a while. The key is in creating extra partitions and moving the Nook software to the new partitions. Various guides are available, e.g.
http://forum.xda-developers.com/showthread.php?t=1275859
I eventually simplified my family installs down to just cm7 as we ended up never using the stock Nook. One can use the Android Nook app for basic B&N content but if you use for magazine or childrens books then that is a good reason for maintaining a stock Nook. I normally use SD installs for any non-technical friends where there is a good comfort factor in an easy revert to stock.
I actually gave up on ever getting a 32gb card to work properly after I went through several of them. I just doesn't seem like the OS can do a good job with all of that extra space.
Things that fly on a 16gb card are terrible on a 32gb card that benchmarks the same way.

does it have SDSDQM-032G printed or etched on the card itself?
thats the model of the current "good speed" ones

If booting off uSD, you should pay attention on the small write data (4K Write)
If it's more than 1MB/s, it's good.
If it's close to 1MB/s, it's OK.
If it's somewhere around 0.0xxx, then it's bad for NC
I bought four (4) Sandisk32g cards from geeks.com,part #SDSDQ-32GB.They are testing out great.The (4K)writes are 1.277(slowest card) to 1.613(highest card).
($28 /card and free shipping)
I also tried their 16G Sandisk cards,VERY BAD,they test out at 0.024 (4K)write

I bought two 32 GB Sandisk Class 4 cards from 1SaleADay in October. One started experiencing Force Close errrors on my Nook Color after 4 or 5 months. Eventually it could not even unpack the zip files and build properly. I copied a working image from another flash onto it. It then worked until I started updating and installing apps. It seems that writing to some area of flash, not sure which partition, triggers the start of the force close. During some tests, it would run until I enabled WiFi. I think apps were accessing the WiFi and trying to write to flash.
The 2nd flash from 1SaleADay was used by a relative. I updated all app in December. The relative played Freecell and maybe a few other apps once every few weeks. As soon as I attempted to update apps here in May the Force Close issue appeared. The NC had been running fine with the December updates.
A co-worker bought the NC based on my recommendation. He bought a SanDisk 32GB Class 4 card from a reseller at Amazon. He started experience Force Close issue shortly after mine.
All three 32GB cards had great ramdom read/write 4K benchmarks like other SanDisk cards. I used CrystalDiskMark to test the cards when they were new and when the first two failed. I also ran H2testw on one or two of the first cards that experienced the Force Close errors. All tests indicate the flash is still good.
The first two NCs have been running fine now for a few months with 16 GB SanDisk Class 4 cards I bought in September from Newegg. I need to put a 16 GB in my relative's NC.
I did buy some more 32 GB SanDisk cards from Amazon (not a 3rd party reseller) for $22 a few weeks ago. I hold little hope for them to work for long in a NC. I may try one. I bought them primarily to use in other devices.
The first card to fail has been running fine in my non-rooted HTC Incredible 2 for months now. I use it for podcasts so I am reading and writing to it daily but am not running the OS from it like the NC.
Running the Fix Permission function of the ROM Manager did not eliminate the Force Close issue on my relative's NC.
Thought that was supposed to be the best card to use

I think I read that the max card size for HD2 is 16Gb but can't find it (in the manual or searching here). What's the biggest card users are using so far? And an views on make / speed etc? I'm not running apps from the card yet but may do in the future.
Thanks for any info in advance.
I've got a 16gb SDHC Class 2 card in mine at the moment and am happily running apps, games, movies and music from it without any problems. Also used an 8gb SDHC class 4 card without any problems too.
Think I read somewhere that 32gb cards will work with the HD2 but can't remember where. Are 32gb cards out yet?
The biggest card it'll take is 32Gb, but I haven't seen anyone selling those yet.
Not sure how much of a difference the speed of the card makes - I've heard people say it does matter, and others saying it doesn't matter when dealing with a phone, cos the phone could only communicate at a certain speed with the card anyway (as opposed to a computer with a direct USB bus access). I'm not sure if anyone's tested it conclusively.

Hi all,
Apologies for the rambling post below but....
I would like to report major problems I have experienced with 32gb Micro SD cards with a number of Android devices, and most recently my new Desire HD.
The problems occur when I copy across my music library to the 32gb SD. It is a mixture of MP3 and AAC (mp4) files and the initial amount of data is a minimum of 5gb. All the data copies across fine, as I can tell from the available space under settings/SD & phone storage. However, the stock music player app does not recognise roughly half the music, and some of the music it has recognised produces a "cannot play this file format" message if i try and listen to it.
Using Astro File Manager, I then browse to the location on the SD card where I have copied the music and find that the music (that was not recognised) , is not physically on the SD card (despite the available space remaining suggesting the files are there).
If I then copy new music to the Desire HD on the SD card, the music copies over but the same scenario above occurs.
If I keep the SD card in the phone for 24 hrs the phone will crash numerous times and the only way I can turn the phone back on is to remove the battery.
I have tested 4 different 32gb Micro SDHC cards, 2 Class 4 SanDisks and 2 Class 6 Kingstons, same results with both.
Phone-wise, I have tested this on an HTC Wildfire and Samsung Galaxy S (running Android 2.1) and an HTC Desire and HTC Desire HD (running 2.2). I will test on a Samsung Galaxy Tab tonight.
Also, I have tested the above after formatting the SD card in the devices themselves, and from formatting the SD card from Windows 7 using FAT32 and 32kilobytes as the allocation unit size.
Has anyone else experiences issues with 32gb Micro SDHC cards? FYI, the stock 8gb Samsung SD card that comes with the Desire HD works without any issues whatsoever.
regards
Michael
I'm so glad you've posted these findings, I was contemplating buying a 32GB microsd card but could not justify paying more than twice the amount it costs for a 16GB card. I think I'm going to settle with a 16GB card now.
EDIT:-
Just thought about something, where are you doing this from, Windows 7 ? There is a Microsoft Windows update that fixes a problem with Windows 7 not reading 32GB or higher memory cards properly.

Very interesting and useful info for who tend to use 32GB microsd with DHD.
Is there anyone using 32 GB without any problem? We need to find out if DHD has a common problem with 32 GB or not.

I have one I got last week thats working perfect! 32GB class 4 from mymemory.co.uk (their own card, no manufacturer name).
I've copied a bunch of music and some HDTV episodes onto it so it's almost full, all files are definitely there and I've had no issues with playback. Using Astro too.
Copied them over on a Windows 7 system with Android Manager WiFi, I've used the regular USB cable once or twice which works fine too.
I also have a 32gig card.
Initially I had similar problems to you bit sure what fixed it, HTC sync works and I did reboot one or twice, but its all working

No issues with my Integral 32GB Class 4 card.
Try formatting with 32k cluster size...I've read that it helps with stuttering video issue, maybe it also helps with this...
Then nice to know it's a spesific problem not common. Thanks for the feedbacks guys.
I'm having exactly same problems as post 1. Someone suggested it might be a fake 32GB card so I'm currently running h2testw on it to see.

That was the case with my 32GB one. h2testw reported only the first 1.8GB usable.
I suspect these are factory rejects being snatched before being destroyed/recycled.
I've been using a Kingston Class 4 32Gb card for 2-3 months now with absolutely no problems. Almost full of music and Sat Nav maps, and not even a hint of problems. Make sure you buy from a reputable, or at least traceable, supplier!
Sounds like the card is faulty or fake, ALWAYS test with H2TESTW and format it with Panasonic's SD Formatter app BEFORE using it with any device! Too many dodgey cards out there!

Mind if I ask where the hell did you find 32GB class 6 Kingston or other cards.
I can't find anything higher than class 4. Also on their official page there aren't any 32gb microSDHC class 6+.
Ho everybody this is the answer. I have bought over 10 32gb micro SD cards from eBay and amazon.
Some would not even format. Dome would format but while trying to transfer the files half way through the card would fail and would not be able to format or only see the card as 8gb.
Some would format and transfer would be good but by the time I would check for the data on the card the data would have disappeared.
Let me make one thing clear ALL THESE CARDS WERE CHEAP NOCK OFFS AND CHEAP QUALITY FROM CHINA.
I payed from £25 to £80 from eBay and amazon and they all failed.
I bought ONE FROM SCAN.CO.UK and it worked first time and still works with no issues thank God.
IT IS NOT THE DHD IT IS THE CARDS.
The reason they all failed and why its so hard to believe is because not everyone that buys the cards would transfer so much data at the beginning which is why the card failed, the huge amount of data being transferred showed the true defects in the card.
I really hope this helped.
Kind regards

Hi Everyone,
I have read the extensive thread on compatible SD cards, but just wanted to open another thread asking if there are any known 32GB cards working with this phone or if you guys have heard of any officially certified 32GB cards coming soon. I am DESPERATE to have more storage on my phone, but will not buy a card unless I know it is working for sure and want to go for the 32 as soon as possible. Thanks!
Well I can only speak on my personal experience but I've been using a Kingston Class4 32GB card since November 8th and have never had any issues. And I'm sitting at around 12GB of usage (music, videos, etc).
I'm not saying this is gauranteed to work - just relaying what my personal experience has been.
Use at your own risk...
My Kingston 32GB C4 card lagged really bad once I got over 10GB. There are so many conflicting reports like this. Using any card is a bit of a gamble at this stage.

I'd be curious to see what happens when you get over 16GB. It seems like 8GB cards are okay; maybe there's something that freaks out when you use more external storage than internal.
I also would be interested in what happens once you fill it past 16GB. Would one of you be willing to give it a shot for us? Thanks for the replies everyone!

I recieved that card from Amazon early this week but so far all I've done is benchmark it. The card is pretty impressive with sequential and random read-rates but its write speeds are about the same as the Sandisk Class 2 I currently have in my Focus. Right now I'm waffling on wether to go through the process of swapping the cards and reinstalling everything or waiting until the NoDo update comes out. If I do make the swap I'll probably post on the working sd cards thread
samsung is dropping their 32gb card this month...
I ordered the Samsung Focus with Amazon Wireless for one penny and a two year contract with AT&T! Couldn't be any happier with that.
Anyway, I ordered a case:

And a screen protector (I know it's tough to scratch but eh, why not. Lol)
http://www.amazon.com/gp/product/B003F8C1GK/ref=oss_product
So I've been thinking about how much memory is on the phone. 8GB is nice but I will want to put a few of my 720P movies onto the Focus. I figured I could get 8B Micro SDHC (Class 10) and it would make it, 16GB. That's pretty decent, right? I think it will hold me over... Lol.
I did some research and I get the higher the class, the higher the write speeds. Right?
Well, what do ya'll think of this one?

8gb is good enough for me....for now! Ill be buying a 16gb card soon enough tho because everytime you change the sd card you have to do a full reset on your phone, so id rather just do it now and get it all over with. So, what im trying to tell you is just get yourself a 16gb card if you going to be adding 720p movies...that way you wont really need to worry about changing the card later. As for the class...class 10 is unnecessary....class 2 has been proven to be VERY sufficient in the focus...even class 4. I had a class 6 and now I have a class 2 and there is NO difference in performance on my focus. Anyways, as for sd cards, be careful because some aren't working properly....I would say your safest bet is buying Sandisk...since thats what Samsung is using in the focus for memory right now.
Hope this helps!

Well, if I put a 720P movie on there, I'll just delete it once I'm finished watching it. Not going to have more than a few gigs of music too. So 8GB is good for me. Obviously once you put a movie on there you can delete it and get your memory back, correct? Sounds nooby but just double checkin... Lol. The higher the class the faster it gets on the card, right?

correct...once you delete things you get your space back. I didn't notice much difference in transfer speed between my class 6 and class 2. So if you can, just save yourself the money and get class 4. There was an article I read somewhere that a higher class can actually make performance worse on the phone. Don't know how true it is, but class 2 has been perfect for me. No difference anywhere.
You need too spend some time reading this thread before buying a microsd card:
http://forum.xda-developers.com/showthread.php?t=834144&page=3
Determining whether an SD card is Windows Phone 7 compliant is not a simple matter of judging its speed class. Several other factors, such as the number of random read/write operations per second, play a role in determining how well an SD card performs with Windows Phone 7 devices.

A higher speed class can actually work against you because sometimes the maker sacrifices random operations for speed.
You can either wait for official "windows phone 7 certified" cards or take your chances. Read the first post carefully, especially the most recent posts. I personally have been using a 16gb Samsung card with no problems. Caveat emptor.

Patriot Signature 16GB Micro SDHC Class 4 Flash Card Model PSF16GMCSDHC43P
http://www.newegg.com/Product/Product.aspx?Item=N82E16820220524
If you read the feedback, nothing but positive reviews.
"Pros: Very good price to performance ratio. Works with the Samsung Focus. Good read write speeds.
Cons: None
Other Thoughts: Not sure why some say negatives about the speed of the card. Maybe they got a bad one, but this tested out at just under 4.5gb write speeds. I had been using a Sandisk class 2 card with my Samsung Focus, but it would do some random rebooting and crashing. With this card it has been absoulutly perfect for over a week of use. I have 15gb of music and photos on the phone so I know that I am using the memory card along with the 8gb that is onboard with the phone."
Kinda sold on this... Should I do it?!?!?!?! Buy it right now?!?!! lol
This is pretty much what I was asking in another thread. I want to go with a 32GB card as I don't want to go through hard reset if I ever need more memory later on.
What is a good 32GB tmicroSD card hat works with Focus with no issues? I would like name of manufacturer, class and even the part# so I can source locally (go to store or order online).
Thanks.
No lie, you're going to spend a lot of $ and 32GB is overkill.

After reading the large thread on compatible cards above, it seems the real test is if you've loaded over 8GB of data onto the SDHC card (or over 16GB total in your case) and don't experience any problems. If that's the case then that's awesome (and it also sadly verifies the fact that no one knows which brand of card really works than the Sandisk 8GB Class 2, which is mentioned in the official instruction manual).
To the OP, I've stuck with the 8GB Sandisk. I considered the OEM version for $12 USD available on Amazon but decided against it, and went with the retail packaged version, which I got at Radio Shack for $20 USD. 14 or so GB will be good enough until the official certified ones are announced.
well ill just refer to him as mr arse... but mr arse is partially correct.... mine was stable up to 15gb then after that it went downhill fast.... so give the dude a bit of a break....
Has anyone seen any OFFICIAL announcement that there will be APPROVED cards for WP7. I know that Sandisk tried to pull a fast one and say their's were approved but then pulled them. Is MS even allowing such a program?
Where did you guys buy your micro SD cards for a cheaper price and how many gb should I get if I want to run cm7 off of the SD? Thanks guys

The NC can support 32G uSD, majority of people uses 16GB or 8GB Sandisk, class 2 or 4.
Some reported Sandisk cards from ebay are counterfeit.

I have three, 4 gb sandisks.
1 is my cwm recovery and allows me to put in nandroids as I need.
The other two are test installs, one for miui and the other for cm7, but.
I have one 8 gb that is my stock 1.2 nook ereader on it.
My nook as a 16 gb sandisk now with cm7 on the emmc.
I have a 32 gb sandisk that I am trying to decide if I am going to break it out and use it since my current 16gb disc is at 14 gb full.

According to other members, Sandisk class 2 is one of the best for NOOK, 4GB seems to be low (the ROM itself - /system - doesn't take that much) for storage but you actually have at least 1GB on eMMC or potential 5GB (if v1.1 or re-partition)
uSD = µ for microSD
Extensive testing, many MicroSD purchases later, and near a dozen SanDisk MicroSD cards says that this link:

Will get you the best cards I and at least one other member here have been able to find.
I've put a lot of work/research into this running from the MicroSD card issue, see my sig for the two threads you should read to understand it.
The 16 Gig SanDisk cards i've gotten from the link I just posted have tested to the best benchmarks i've run so far - and I very thoroughly benchmark my cards.
Best of luck to you!

Sweet! Thank you, mine is already on it's way.
I know you'll like it - it's great to be able to take the guesswork out of finding something that works so well.
These cards were originally found by user busyworked, and he put quite a bit of research into tracking down model numbers to locate these specific cards.
The original post is Here.
One of the things that makes this community so fantastically great, is the amount of work that people put into this stuff on their spare time. By keeping the record straight for who found (or did) what, we can keep building on that knowledge without crossing the same ground. It's also great to make sure the right people get credit for what they've done.
I'd hate to take credit for anothers discovery, just want to make sure others know how much effort he put into finding that gem of a card. I didn't have enough time earlier to link the post, but the shopping link was a shortcut on my desktop and quick to call up.

I got this card but it came "oem" No packaging and couldn't tell if it was new. It wasn't described as oem in packaging from Etech, very annoyed by this.
Keep your fingers crossed that it isn't a counterfeit.
Yeah, I hope it works when mine arrives too.

I have one of these, it outperforms every other card i've been able to get my hands on.
Forget what the packaging was like when it came in, but shipping was quick.
It's marked in the same fashion as another SanDisk (8 gig class 4) card I bought at Radio Shack.
My 8 gb sandisk from etech was in new retail packaging.
My 16 gb sandisk from etech was OEM (no package, no nothing for that matter).
The 16 gb sandisk seems to work just fine, I've had it for about a week and a half on my nook color as it's primary sd card with emmc with cm7.
After thinking about it more deeply, my 16gig card came in just the small plastic case with a full sized sdcard adapter, no original packaging.
I run my OS from the card, not emmc, and it is fantastically better then other microsd cards i've used.
It doesn't bother me that it wasn't advertised about the packaging, but I can certainly see how some(probably most) people would be ticked about it. I concede without question the legitimacy of the argument.
I defray the idea that the card may have been previously used by the amount of business the company does. I think they pump more volume out then they could keep track of an 'employee loaner program' or whatever.
At least this thread has borne out this fact, so we can say buyer beware of the packaging issue.
That said, it's still the best MicroSD card we know of - unless some of the people researching the "operating system from MicroSD" situation have some hidden gem they aren't talking about.
(I sincerely doubt this, it's like the complete opposite of the spirit of the place we are in...tantamount to committing sacriledge in a church or something)
Sorry, I didn't think to mention this.
Both 16gig cards I ordered from there came in OEM packaging, didn't seem like a big deal to me at the time.
I never considered any of the thoughts surrounding that revelation, or I would have made it known up front.
My apologies.
(still a rockin' card though)
I'm happy with mine. Can't beat the $17 Amazon/etech charged. Aside from the shipping envelope it came in, packaging looks just like I'd see it on the shelf at walmart...
Works great too!

I bought this one to use it in the NC. Very fast, comes with adapter.
Free shipping. The store itself is very good, respectable. I have bought laptop from them before.
I get all my electronics online, almost always from Amazon.
The size sd card you should get depends on what you want to keep in your nook.I don't store music our videos on mine so 8gb us plenty for me.
