I installed CM7 on EMMC and under Settings-->Storage, I am only seeing ~0.9GB of internal memory - wondering what happened to the rest of the 8GB? Not talking about an insertable SD card here, but the built-in memory on the NC (8GB Sandisk SDIN4C1-8g).
I had this same issue with Froyo, and brought it up but didn't really get any feedback, so now I'm wondering if it's just my install?
My SD card is only 2GB and I use my NC as MP3 player for the car, so it'd be really nice to be able to load up a few more tunes again. Besides this, CM7 is pretty awesome.
not just your install, I am seeing the same thing on mine. I also see the same thing on the honeycomb builds i've tried
i think thats just how the internal memory is partitioned... it'll prolly be fixed by the time a stable cm7 rom is out
Appreciate it! Glad to know I'm not the only one
Known issue that is being actively worked on. Has to do with how the partitions are being mounted on start-up. The other 7 gigs are sitting there unmounted in all current Gingerbread and Honeycomb ports.

Hey everyone,
I currently run CM7 off an SD but I was wondering if there are benefits to replacing the stock os on the emmc?
Are there any speed differences or technical pros to it?
Thanks for the input! This is a really fantastic forum!

From my experience the booting time is almost half if using emmc version. (SD card version ran on a class 4 card). After booting the performance is almost same. You may get better boot time for sd card using a class 6 or class 10 card.
I dont have an answer for you as i picked mine up yesterday and decided to go the SD route at the start i am curious on this question myself.

Well from my experience, running from the SD card is very smooth... so for ease of use i highly recommend it for a first go.
I have a follow up question- for some reason my macbook recognizes the second partition of my sd card but my pc desktop does not. I am referring to the partition generated for storage by the CM7 installation process that allows storage on the data card simultaneously.
Any ideas why this would be?

I use Macs and Windows machines rarely (and I am guessing you run Windows on the desktop) but my guess is the ext4 partitioning that CM7 uses.
I seem to recall that working- at least somewhat- on Mac but not on Windows, but I am not positive.
i chose sd, because it's super easy to backup my sd card as an image by popping it into my laptop. I can then burn that image back to a sd card if i want to try a new android build without messing up my default android install. I can always boot into the original nook os if i want as it is unmodified.
i used a class 2 and it was pretty slow. moving up to a class 6 and 10 has really helped and i don't notice any slowness.
i have not run off internal memory though so i don't have a baseline to compare.
eMMC is faster than my class 2 uSD cards, and it's easier to swa stuff back and forth from a computer/phone/camera/whatever with a removable uSD.

Cool, I've been wondering about this myself and was about to make this same thread.
I was concerned because I get a ton of force closes running off the SD, and I wondered if that was a problem that would be solved by going to eemc. Or if somehow I've made a mistake setting up my card and that's the issue. I'm very knew to this whole scene, so I'm still a bit scared of rooting at the moment and would love to iron out the problems I'm having with the SD booting. Things run fast, and fairly smoothly but eventually something will force close, like Market, and then Google Frameworks and then pretty much everything will refuse to run after I tap their icon. Forcing me to restart. Also, some things, trying to download new skins for Beautiful Widgets is impossible. Only get force closes.
I can't figure out if it's anything in particular that causes it to spiral out of control. And what makes it more annoying is this is my girlfriend's new Nook, I'm trying to get it set up for her to work as smoothly as possible. If it was just mine, I wouldn't be as bothered by messing around and trying different configurations and whatnot. But I know she won't be as patient and tolerant of these issues and won't want to keep bugging me with every problem that pops up.
Would you say this is likely a localized problem on my end through some fault of my own? From this thread, it seems people are having pretty great experiences with the SD method. Which might be reassuring. I think I'll do a backup and start from scratch this evening.
@JRSly: What type of uSD card are you using. I was experiencing the same problems you had with booting, force close, refuse to run, thus a final restart. After swapping out four different types of uSD cards, SanDisk (class 2 and 4), A-DATA (class 6), Patriot (class10), I finally deteremined that the Nook is very picky about the type of card. All the cards work fine in my digital camera or PCs, but the A-DATA and Patriot are slow and often hang in the Nook. I am now using the three Sandisk cards with no problem. I recently updated to Nookie Froyo 6.8.5 and it runs great on the SanDisk cards. Just for the test if it will run faster on A-Data (class 6), wouldn't you know it starts to hang and FC just like before. I guess I'll use the A-Data card in my digicam. Try a Sandisk card and see what happens. I even try one of my old Sandisk 2GB card from my Blackberry which is unmarked but has a class 10 performance when measured.

I feared that this might be a possibility too. My first attempts were with a little 2Gb card I'd had lying around and it didn't work very well at all. I couldn't get past installing Gapps for all the force closes. The next day I went to Target to get a larger 8 Gb one so I could also play around with Honeycomb, it's a Class 6 Lexar card. I started over last night and tried a couple of attempts at wiping and burning the image and inevitably ran into the same problems. It looks like a crummy(at least in terms of what the Nook likes) card is a distinct possibility. I'll give Sandisk a shot.

Yup. (I didn't get it either.)
Since MMC is a sibling of SD cards, it's basically dedicated internal SD storage with a controller.

You got it in one.
sd card is self explanatory, of course, and emmc is the internal memory of the NC.
The only DISADVANTAGE to running on emmc is that you lose the stock B&N version of Android.
Other than that- it boots a bit faster, may run a bit faster and be less likely to have force closes and similar problems.

Thanks for the cofirmation
Currently I am running CM7 off internal memory and I have a SD card that has the apps and what-not on it.
I bought another SD card with the idea of making it a bootable Honeycomb install so I can try it out. I mean I completely enjoy CM7 and have everything set up perfectly the way I want it, but I also like trying new stuff.
So the question is this. Is it possible to do this in a way where the HC install won't affect the CM7 install? I mean when you go to install an app on HC would it put stuff on internal memory or somehow screw up the CM7 install? The idea is that when I want to go back to my stable CM7 I would just put its card in so the second HC card would just be for screwing around.
Anyway...that's the question. I'm guessing if I dug around enough and pulled information together from multiple threads I might figure it out, but perhaps others are interested in doing what I'm talking about too...so hopefully this is a useful post.
If you are running a ROM from SD, everything will be on the SD. The ROM is setup in such a way that it thinks the SD card is internal memory, so everything will get installed to it.
The only downside is that SD is much slower than internal (especially if you don't have a good card), so the experience usually suffers a bit.
You can certainly do this. I'm running stock 1.2 on EMMC and have a dualboot SD card of Phiremod(CM7) and Honeycomb (the latest version from Divine_Madcat). Nothing on internal is touched.
http://forum.xda-developers.com/showthread.php?t=1045018
Regarding performance on SD, I have a transcend, class 6 that works flawlessly for CM7 and is a tad slow on Honeycomb. Might pickup a class 4 Sandisk tomorrow (if the price is right!) as i've heard that those are the best and are consistently faster.
Thanks guys. Got it going and its not half bad. I think that if the EVER release the source, this would be an awesome OS for the Nook.
HI..
I’m new in Nook color. I have just bough nook color and an 16GB SD card with Gingerbread 2.3.3 Mod version Phiremod Nook 6.3 Build No. GRI40.
I have not any problem for 1st time booting, but afterthat market wont work, after several cache & data clear up market is back to normal. Then another problem has been found,
1) Internet connection is really slow. My wi-fi setting is set to WEP security (if i change it to W2K or something else it will not detect my wifi), signal is excelent, but sometime i even cannot get into google,I think there problem with the software and connection, seems the nook is very slow also even when i click a thick box it will take around 2-3 minutes to response. What will be the possible issue?
2) When I want to reboot or powering off the Nook another problem has come, the nook wont reboot neither powering off, it hangs and freakin’ me out and i must hard force the power button to kill the nook. What is the cause?
3) Nook shall come with 8GB internal storage, but why in the Storage it is mentioning the total space is 0.93GB and available space is 874MB. And my SD card(16GB) is only 2.24GB instead of 16GB.
Please help me all expert.
I start love Nook the first time i’ve seen it, but after getting some confusion with this I start to thing twice to have rooted tablet..please help me to start enjoying my nook.
Thanks ALL

There's the thread for Phiremod. I would guess some of your issues might be addressed in that thread.
You aren't going to be able to change the partition sizes without destroying your non-SD card build (presumably the stock Nook ROM).
My recommendation is forget the Phiremod, all that does is remove you from the official CM7 update paths and in turn you get no real benefits, no support and lagging updates and fixes.
Install the latest CM7 nightly(177) onto your emmc, most, if not all of the issues you are having should go away once you've done that.
you can follow this guide
http://forum.xda-developers.com/showthread.php?t=1030227
I hope you didn't pay much for that card, because if you want to fix any of these things, you will probably have to start from scratch and make your own, anyway.
Your performance issues very likely relate back to that card. It may be that they used a poor card in the first place, but even if they used a decent card, sometimes SD installs just don't come out quite right and need to be rebuilt from scratch.

That's how newer NCs are partitioned. There's a 5GB partition that you can't see where Barnes & Noble apps, books and magazines would install, and only 1GB for you to sideload. The remainder is used for boot files and recovery images. You can reverse that partitioning so you have 5GB available using the method here: http://forum.xda-developers.com/showthread.php?t=1094371

You may be able to claim the remaining space using a program like EASEUS Partition Manager, assuming it was in fact a 16GB card. If you look at the card in EASEUS on a PC and see a lot of unallocated space, you can extend the partition named /sdcard to take up that space. If the card was set up that carelessly, though, it's very likely the people who made it didn't know what they were doing and the card will never perform well.
Also instead of WEP use WPA2 for best results.
I bought the card less then 50$, the brand is Paxxxxt. The seller has inform me that there might be an issue with the card, because the speed is too slow. He said from thousand of his cards there are 30 something are having this problem, so he send me another card (sanxxxk), it will arrive within next week, hope it will work.
Thanks to all experts.
I have set up the CM7 on an SD boot and it works for the most part.
However it seems very unstable, about 3/10 uses it will crash apps. I really only have Aldiko and the Nook App on it and maybe Angry Birds and a Task Killer.
Aldiko and Nook etc will just go into an error loop saying the app stopped unexpectedly and then I have to hold the power button to shut it down.
My question is if this is typical of using the SD root method?
Then, if I do a full hardware root/ROM is it generally more stable in your experiences?
I suspect that part of my problems are the SD card itself, I had a 4GB Class 2 Sandisk card initially and it worked well but it was very very slow. So I got a Transcend brand 8GB Class 6 card which should work, it is a big name brand and all, and is much faster but CM7 seems very unstable. Is it all just the card?
Yes, your card is the culprit. So far from people reporting here you need a SanDisk Class 4 card. Its all about the 4k read/write speeds of the card you're using. You want a 1.0+ in CrystalDiskMark to get decent performace and get rid of the FC's. I am using the card I linked here and have not had any problems running apps or the Nook freezing.

I had similar problems (sometimes intermittently) using an A-data card, I think it was 8GB class 6. I finally installed to emmc and have not had any problems since. The CM7 nightlies go to the point of being so good that I never needed to boot into stock anymore anyway.
So if I get it working on the SD, is it even worth doing the perm internal ROM mod?
Or is the SD MOD just as good/better?

Running off the SD is so good I haven't even felt like trying to put it on the internal memory. The only thing you lose by running it from the SD card is the ability to pop out the SD card whenever you want, though the only times I've popped out the SD card is to put the newest nightly on the boot partition. And thats just cause I've been too lazy to figure out the exact mount commands to mount it on the nook. If I want to get/put files off/on the SD card I just plug it into my computer.

I didn't run any benchmarks when I had it on a SD card (16 GB SanDisk class 4) but it seemed about as good as it has been after switching to eMMC.
The CM7 SD card mounts internal memory on mmcblk0 and uses it... (I presume for caching, etc) Speed of the SD shouldn't cause crashes. Slowness yes, but crashes?
Re: SD vs. eMMC, an SD install can be just as fast and stable as eMMC, but SD installs also seem somewhat prone to suddenly and mysteriously losing that stability, developing FCs, WiFi issues, lag and even freezes/crashes. There are also more robust and straightforward tools for managing eMMC installs; both CWM and ROM Manager tend to have quirky interactions with SD installs, performing some operations on the SD partitions and others on the internal partitions. I would advise anyone who finds that their SD install has become their sole or primary OS to eventually move it to eMMC. Even if you're still using stock quite a bit, an eMMC dual boot (see my sig link) has advantages over running one system from SD--mainly, that the two OSes can both use the SD for storage.

See this thread: http://forum.xda-developers.com/showthread.php?p=12964262
There's no such thing as "Speed of the SD." There are several metrics, primarily large sequential vs. small random reads and writes. Card class (what most people assume equates to "speed") is based on the former, whereas performance as a boot drive correlates with the latter. A card optimized for large writes tends to suffer badly in small-block random r/w. There's no such thing, presently, as a card optimized for small-block r/w, but SanDisk class 2, 4, and unclassed cards tend to have very balanced benchmarks, with reasonable performance across all metrics. This places their small-block r/w speeds 10x and 100x ahead of a card optimized to meet class requirements.
I've also been hearing there's an issue with some cards reporting their reads and writes using an oddball protocol that's currently unsupported in the kernel.
Is anyone running their rooted nook without an SD card?
I can't seem to get Aldiko, Bluefire, etc to work without the SD card even though I've got a ton of space internally.

You can swap "EMMC" and "SDCARD" in android fairly easy (to trick android into thinking internal memory is a sdcard... apps save stuff there and you don't have to use an sdcard at all)
In the newest CM10 builds just use any ole filemanager thats usable with root and edit /system/etc/vold.fstab
it will look like this with some more stuff commented in
dev_mount sdcard /storage/sdcard1 auto /devices/platform/omap/omap_hsmmc.0/mmc_host/mmc1
dev_mount emmc /storage/sdcard0 8 /devices/platform/omap/omap_hsmmc.1/mmc_host/mmc0

Notice that its mounting emmc to /storage/sdcard0, simply switch out the sdcard1 directory for sdcard0 and put it below for EMMC.

cm7 is similar, i believe it uses /mnt/sdcard and /mnt/emmc though. But just take a look. Also, make a backup before you do it, if you mess it up you will get stuck in a bootloop.

My nook has seen better days. Even had a son throw it against the wall (I include this because it may be why mine slows to a crawl moreso than I'd like). Only real way I've made mine quit lagging is by setting it so there are no background processes in the developer options. I'm sure there are ways around it, but I don't really multitask on the nook so it works fine by me.
Seems to have done the trick! Thanks viogrep!
Just repartitioned my Nook to 2gb data / 4+gb media. Will use a fresh the CM10 nightly build on it. This is looking really good!
I use the Nook mostly for 90% books, but also load it up with a some music, movies, and games for when I'm on the road to keep from boredom. I've had the Galaxy Note, but ended up coming back to the Nook. Recently picked up an Asus Transformer Pad TF300T and I can see myself using the Nook for long, long time for reading... and more since it's just so much more portable. I really don't have the need for cameras, gps, or any other features on this thing since I already have a phone that can do that.

One small bit of info for you. Goomanager and the like won't be automated anymore. As it will reboot into recovery and think the update is on the sdcard when in reality its on the EMMC. You just have to manually flash from the EMMC in TWR.
