Are you saying this doesn't work? It's working fine for me. Make sure you don't have a counterfeit. Apparently if the black serial numbers are not printed card it's a fake.
I can add that I didn't have any luck with the Patriot or Wintec 16GB cards.
8GB Lexar C6 does work.
My theory is the card needs to have good random write performance 512k and 4k. If 512K is 2Mbps or better seems to work. This was tested using crystaldisk mark using a USB 2.0 adapter.
Also note, performance of a particular card isn't exactly easy to determine. If I use different devices to adapt a card to the PC I get different speed results. For example on the same card, I got .5 Mbps 512k random speed using a Dell E6410 adapter, but 1Mbps using a usb microsd adapter.

I have a class 10 16g ADATA. I ran into the endless loop fc problem for 0.6.7. I formatted the card from nook stock rom then ease it from my MacBook pro by using disk utility. The endless loop fc problem went away afterward. I am still having problem with the honeycomb v4. It gave me a "enter password to decrypt the storage" screen after it boots up. No idea why it is that. Kinda frustrated ....

Speaking of counterfeit SD cards, this isa HUGE problem on ebay. Always purchase from a trusted source.
If you suspect issues with your card, H2TESTW is considered one of the better testing and benchmarking tools. Very small, very simple:
H2testw 1.4 – Gold Standard In Detecting USB Counterfeit Drives
Sorry to resurrect a month-long post, but I wanted to add my experience since I'm seeing some really unusual behavior.
16 GB Class 10 Patriot w/ Nookie Froyo development 0.6.8 - worked
16 GB Class 10 Patriot w/ Nookie Honeycomb v04 - booted but always asked for password
Here's where it gets weird:
16 GB Class 2 Samsung OEM (came with my phone) w/ Nookie Honeycomb v04
The first boot immediately after burning the img to the card will work. I boot into Honeycomb, I can play with all the features and apps, change settings, etc. It seems to work fine.
If I shut down and boot it again, it will hang at the Android boot screen. The only way I can get it to work again is to re-burn the img to the card again.
BTW, the CrystalDiskMark scores to the best of my recollection:
16 GB Class 10 Patriot
seq: 19 MB/s read, 15 MB/s write
512k: ~8 MB/s read, 0.7 MB/s write
4k: ~3 MB/s read, 0.006 MB/s write
16 GB "Class 2" Samsung
seq: 15 MB/s read, 11 MB/s write
512k: ~5 MB/s read, 0.6 MB/s write
4k: ~2 MB/s read, 0.012 MB/s write
Apparently Samsung is very conservative in the class rating they give their memory.
I've got a 16GB Sandisk microSDHC card with adaptor. It says '4' on the card's sticker, so I'm assuming it's a class 4. Does this mean my card won't work?
Also, I'm using it in my Samsung Galaxy right now. Can I just transfer the files to my PC and format the card, before using it for rooting the NC?
TIA.
Kingston 8Gb class 4 nf6.8 - boot but has problem with market.
Took me hrs to realize it was the card.
I am using patriot class 10 8GB
Works great. No problem so far. As fast as emmc 1.1 root.
wish i wouldve looked for this kind of thread sooner. bought the 16gb patriot class 10. doesnt work returning it for another class 10 8 gb
16GB Class 4 Sandisk
No problems so far 0.6.8
anyone have any review on KingMax 16GB micro SDHC class 10?
thanks
Since I plan to have videos I really want to get as much storage on a single card as possible. I DO plan to boot 2.2 (until 3.0 is ready for primetime) from eMMC, but I want to be sure it will be compatible.
REEDIT: Yeah it does support 32gb.
Anyone tried any 32GB cards?
4G class4 Toshiba worked for me
I've also tried the class 10 WinTec 16GB uSD. I can get Nookie FroYo to boot but I'm unable to installl apps from the market and most of the preloaded apps will hang at launch. I've tried multiple downloads from multiple sources and they've had the same results. The sdcard works fine with my laptop and camera, fwiw.

(Note: All testing done with CM7-RC4)
Patriot 4GB Class 10 - Installs and will boot, but MASSIVE lag/stuttering, erratic behaviour, slow download speeds from Market (2-4KB/s, bursting to 200KB/s now and then). Definitely seems like a problem with class 10 cards.
SanDisk 8GB Class 4 - Works perfectly; hard to tell it's running from MicroSD and not internal memory aside from a slightly slower boot (maybe 15 seconds more).
Dane-Elec 4GB Class 4 - Works just as well as the SanDisk from limited testing. Took a little longer to cache everything up after the first boot, but worked with minimal initial hesitation after the next few boots.
Just picked up my NC at Best Buy about and hour ago. I have it at home charging and I'm going to go get a couple of MicroSD cards.
Should I go for the Class 10, or is Class 4/6 fast enough?
Unless your running something from the SD card then I'd recomend at least a class 6, you'll get around 11mb/s writing time, otherwise both the ROMs for the nook (Honeycomb & Nookie Froyo) both support installation to the emmc, you can just flash them to your system with Clockwork Recovery.
tldr; if you can find a class 6 or higher for cheap (I got an 8gb class 6 for $12 off amazon) get it, if not you'll be fine with anything truly now.
I am currently using a Class 4 8gb, and have no trouble running apps or even Froyo off the SD card,
Basically if you are just using the SD for apps or holding data, anything should work i would recommend at least class 4 or better, if you are going to be running the a custom rom off the SD while some class4 will work well. I would still recommend class 6 or class 10, Faster is always better.
Posting this from my new NC!
I stopped by Frys Electronics after dinner and picked up two Patriot 8GB Class 10 MicroSD cards. Getting to know the Nook a little before I root and start with the custom ROMs. Gonna load Froyo on one card and Honeycomb on the other so I can try out both flavors and see which one I like better.
So I finally got HoneyComb working on my Nook Color (NC), residing in the microSD card using a Kingston 8GB Class 4. However, this card seems to be one of the slowest and using the HC in NC is almost unusable.
Example:
- Screen rotation takes 3-5 seconds
- Opening new app, depending on which app, can take 1-5 seconds
- Browsing certain website can make the screen unresponsive
- etc..etc..
I know that the HC version available in this website is probably still in "preview" or beta stage and some slowdown is expected, but I am not expecting it to be THIS bad. So I think the culprit is the microSD card itself.
However, I have tried many different MicroSD card and none works. I.e. it gives the "decrypt storage" error when booting up the NC. The cards I have tried are:
- Patriot 16GB Class 10
- A-Data 16GB Class 10
- Kingston 8GB Class 6
The ONLY one that works so far is Sandisk. Unfortunately, from SanDisk website, I do NOT SEE ANY card higher than Class 4.
Thus, can you recommend which is the MOST STABLE and FASTEST card? I.e. the ones that did NOT give slowdown per the examples I have given above.
i'm using sandisk 4 GB class 4 HC
nookie froyo, runs fantastic.
Class 10 cards apparently dont do too well. lots of people have had issues with those. class 6 should be OK, class 2 and 4 workk very nice.
Do you have recommendation for a good Class 6 MicroSD card? SanDisk don't sell anything higher than Class 4. I tried Kingston Class 6 and my Nook Color just spit on it...

I am currently running trancend 8gb class 6. Havent had any issues with froyo, HC or Cm7 booting or running.
I'm using a A-Data Class 6 16Gb card with no trouble. I do have 2 Kingston Class 4 32Gb cards and they have the issue with the decrypt garbage when you try to boot up HC from the sdcard. I've also got a Class 10 32Gb Wintec card which I have not had time to test out yet as I just got it the other day.
After a failed Kingston 16gb class 10, I got a SanDisk 8gb Class 4 and it's speedy enough. I notice very minimal slow down on some menus but I don't know if that's just the OS itself (being a preview after all)

That's the exact same card I have, and you did NOT experiences any of the slowness I posted in my 1st thread?
How drastic is the difference between Class 2 and Class 4?
I know that it says that it processes twice as fast, but is it noticeable? Can somebody give an example of when you can actually tell the difference? Playing music, watching movies, booting from microsd?
I have a Sansdisk class 2 8gb card that performs just as well as my class 10 Patriot 8gb (which has booted both HC and currently used as storage for my eMMC CM7 install.)
Sansdisk severely underrates their SD's and many other manufacturers overrate theirs. It is not a perfect rating system.
I would recommend going w/ sansdisk in whatever size you can afford. Class 2/4 will be plenty fast.
Before I switched back to Froyo I was running off the SanDisk 8Gb card from BestBuy - $20 - which I found very responsive. I think it is Class 4, but I could see any label on the card itself or the package.
The SD card speed was not the reason I switched back, it was the lack of other features in HC preview. I can't wait for an AOSP release
8GB Cards
I currently have 2 8GB microsds that I switch between:
-Transcend 8GB Class 6 running Honeycomb from Amazon. Tested it with h2wtest and got 16MB/s write and 14MB/s read. (Not sure if that is a typo on the tool or not and it's supposed to be bits instead of bytes, but that's what it says).
-Sandisk 8GB Class 2 running Nookie Froyo. Tested at 14MB/s write and 18MB/s read.
Both cards run their respective ROMs well, so it seems to jibe with what chisleu said about Sandisk underrating their cards. I could also be limited by the USB adapter I was using, but I had another adapter that was limiting it to 4MB/s both ways.
Hi everyone:
I have been running 6.8 from my Sandisk 2GB unrated card. Although unrated, the card runs relatively fast with the Nook as measured to my Samsung Captivate or Apple iTouch (2nd Gen).
First Card: I backed up the image from my 2GB to a 8GB A-Data Class 6 card. Now this is where the problem starts. The Nookie boots up but down is acting slow and sluggish. To the point it is unuseable with lot's of FCs. I tried buring a brand new image and it is the same. I also tried the card as a data drive max'ing it out to 8GB and also using it to record video in my digicam, no problems.
Second Card: I then bought a Patriot 8GB class 10 card and copied the image onto it. Even worse. It won't even boot or get stuck in the boot process on the "Customted Froyo" screen. Try other images, and the same things occur. The card also works fine as a data card.
Third Card: Third time's the charm. I got this card from Costco. 8GB, class 4. Copied the image from the 2GB to the Sandisk 8GB, expanded the partition like the others. Worked like a charm and runs even smoother.
My question here is:
1) Is the Nook picky about micro SD cards? Seems like the faster cards are having compatibility issues.
2) For people complaining about performance issues running off of the micro SD card. Could it be caused by compatibilty issues I've experienced?
FYI, I've been running "Customized Nookie Froyo" from my micro SD card for about two weeks now with no problems. This will be my daily driver. I get the best of both worlds, Froyo and the B&N image.
Something to think about
Evidently the NC is picky about cards IF you are going to run from them - which is somewhat more intensive than is intended for an ereader additional storage device.
There are existing threads on the subject, just search TITLES for "card" in this Forum only.
Summary - The Transcend 8gb Class 6 seems to be the favorite. Some Class 10 cards don't work correctly in Nook. A-Data makes great Desktop RAM and crap SD cards. Sandisk is a safe choice when on sale, their Class rating is conservative.
Patriot 8GB class 10
I have the same card and works great. Strange. I don't know why you are having so much problem.
Did you try a new IMg? .3?
i tried the following

I tried .3, 6.8, 6.7, and HC all with boot or performance problems. I have two Sandisk8gb cards now and able to run all images with no problem. Typing in HC right now.

Bad batch? I tried hc .1 .2 .3 no problem. I guess I am lucky.
I have class 4,6, & 10 cards in 8Gb, 16Gb, and even 32 Gb. Mix and match of brands from SanDisk, A-data, Wintec..etc. Only issue I've run into is using any of my 32Gb cards, they just plain do not work right. Whether I use them for just storage or even a ROM running from them they are nothing but trouble. One thing I have noticed tho is DO NOT format the card using Windows before burning an image. You are better off using a3rd party app to format the card, it seems to work much better. Or format them with Linux if you have access to it.
BTW as for the 32Gb cards they don't work well with much of anything. And from reports I've seen on the web it seems to be a known issue where all the mfgs say they can use 32Gb cards but they do not have the software bugs worked out seeing as most people don't own or use them seeing as they are a bit pricey still. At least for a decent one they are
Hey quick question will2live what is the class rating and size on the Wintec card you're using?
I have a kingmax class 10 16 gb card....HC and nookie froyo refuse to boot......well nookie does, but in the next boot, hangs up...
only cm7 runs perfect
I just put one of the CM nightly builds (build38) on a uSD card (sandisk 16gb class 2) and there is a major lag to even enjoy the device. I have been reading about that sometimes class numbers on the cards don't mean too much.
Which card would you recommend to run CM from (Brand/class/where to buy) from your experience?
any class 6 card should be plenty enough (as long as it has enough room for the ROM and stuff) even class 4 should work much better (but still some lag i beleive, idk ive never tried it)
newegg is a pretty good place to shop for them. Heres one such card - newegg.com/Product/Product.aspx?Item=N82E16820211341&cm_re=8gb_micro_sd_card-_-20-211-341-_-Product
There is a long thread about this on here and the class 6 Transcend 8GB card got the most mentions for good perfomance. The probability for issues to arise increases when using cards over 8GB.
I have a class 2 Sandisk 8GB and class 6 Transcend 8GB card. They both work well.
I have been buying the Wintec cards from newegg for a couple months and run them in both my captivate and my nook they work awesome. Class 10 and fast. http://www.newegg.com/Product/Product.aspx?Item=N82E16820161411

I used that card for HC v4 and it was fine.
I've got 4 uSD card: one Dane-Elec 2G no class, one Kingston 2G no-class, one Transend 4GB class 6 and one PNY 8GB class 4. All run CM7 very well, maybe I didn't pay attention but didn't notice much different in performance. In benchmark, the write speed is about 5-7 MB/s.
The higher capactity 16GB card seems to have more problems, other than that every card will do.
You should check into the random read/write performance of small files on these cards. sometimes the class 6 or 10 aren't all they are cracked up to be. Fast transfers of large file yes, but general performance can suck.
sandisk class 2 or 4 cards can have excellent perf. I have a class 10 that is outperformed by class 2/4 and 6 cards.
if you are having problems with crashing, etc. try a basic sandisk and see if perf. is better.
there is a thread about it but i can never find it.
