Hi community!
I just received my Nook Color with a green dot on the box, which seems to be a new variant with 1.2 but without the new partitions. I was able to install Cm7 emmc without any problems.
It's running fine now but almost every app including Rom Manager warns me that there is no sd card mounted. Also I can't seem to mount USB storage when connected to PC. Is there something wrong with my setup or is an additional micro-sd card mandatory? How am I supposed to use the internal 8GB then? I'm really confused right now... thanks in advance.
Oh, I almost forgot: When I press slightly on the frame of the screen there are some "distortions" visible. Is this something to worry about? Also the screen is slightly brighter around the upper middle of the screen, which seems to be the LCD backlight. Is this OK?
Not all apps require SD, but a lot of them do. They don't know to look for that big internal partition, so you probably will want an SD card at some point.
Do you get a notification in CM7 when you plug the USB cable into your PC? If so, have you tried opening your notifications, following the USB notification to the USB Transfer/Debug screen, and hitting the "Turn on USB Transfer" button?
If you've taken all these steps, and you're using a Windows PC, have you tried watching Device Manager while you plug in the NC to see if the PC is recognizing the NC at all?
It may be generally helpful to know what resources you have on hand (type of PC, storage media, ADB, CWM on eMMC), what steps you took to install CM7 on the NC, and what specifically you are doing and responses you are getting interacting with the NC and your PC.
Thank you, it seems that i've simply missed the fact that cm7 needs an sd card for storage.
This makes USB storages work too. When I*turn on USB storage, there are 2 volumes mounted on my PC, the sd card and one titled "MyNookcolor" with 5GB of space. My question is, how can I*acces these 5GB from my nook?
The minor annoyance with the screen I mentioned seems to be a backlight leakage that is common for LCD's. Just curious if your nook(s) have that too?

Isn't that the last partition on the emmc, the one named /media in stock NC and mounted as /emmc for CM7 on SD?

Is there a reason why its better to run CM7 from SD versus the internal memory? Can you revert back to stock if you flash the internal?
From various reports, on a good (Sandisk) uSD it runs the same as if on the internals; plus you can remove the uSD and have B&N stock reader running so it becomes dual boot, and finally since you are not touching the internal layout you preserve all warranty rights. For many including myself, it's a great setup.
I've never overwritten my stock Nook, even updated it to 1.2 software.
I run it pretty exclusively from a MicroSD install of Android.
Firstly - echo the above posting, and can't stress enough how much of an effect the physical MicroSD card has on this kind of install. The wrong card can make it painful.
Being able to just power down, pop the card, and power up to the stock Nook, or another MicroSD card with a different install. (think family sharing Nook with each person having their own card)
Another bonus is that you can boot the stock Nook, plug it in to the pc with the USB cable, and then just drop any files, pictures and so forth onto it. Power down, boot into the MicroSD install, and you can use a file manager to move it wherever you want. Easy, painless way to get pictures and such on the device.
I like having one memory card that is my main use install for the Nook, and having another to test different builds on. It's not hours of waiting to swap the device back and forth, it's minutes of time in between.
Installing to a memory card is a great first step to figure out what you want to use, without constantly re-flashing your Nook.
All this said, i'd imagine that an internal install would overall yield better performance. I'd love to hear from people with internal installs why it's better.
I agree.
Running from the microSD allows you to try different version of CM7 without touching the emmc and in most cases, you will not see the difference.
OK, here's the deal, i got a 32 GB micro sd card ( class 10 ) about 4 months ago now and twice in the last 3 weeks it got corrupted. Some of the files were still available but for the most part, about 80% of all files were unreadable. The first time it happened was after unmounting my card from a mac, the second time i was unmounting from a pc but it was only charging.
I know it might be that the card is dieing or that its a low quality card but does anyone have any specific rules or un-mounting tricks that would reduce the risk of corrupted files on the sd card?
I am always plugging my phone into multiple computers for file access so it has to be something that i can initiate from the phone end.
Do you turn off Disk mode on the phone before you pull the usb cord out? If not, that's generally a good thing to do.

well, which should you do first? turn off disk mode or eject from the computer?
After having that happen with the 16GB SD card in my Nook Color, I pretty much avoid removing it from the device as much as possible. With the Evo, just use disk mode and transfer files that way without ever taking the card out of the Evo. If you ever do remove it be sure the "unmount" it frist from the phone, and eject properly from the computer.
I don't bother with the computer end, for any USB devices. I guess if you did want to do both you'd want to do the computer end first, since disabling disk mode also mounts the sd card on the phone in addition to unmounting it as a disk.
Did you buy it from an authorized retailer?
i bought it from newegg.
well, i"ve noticed that it happened once when i ejected from the pc frist and then frpom the phone.
turn off disk mode...wait till your phone settles and then yank the cord.
I have almost 2 gigs left of memory in my mnt/emmc ...is there anyway I can utilize that space??
Yes, usb cable plugged into your PC, tap to turn on USB Mass storage then use your left-over emmc storage.
Would I just move the files manually when I plug into PC? Ill plug it in and figure it out..thanks!!
I run from a MicroSD install, and use the emmc space on the Nook as such:
Power down, remove SD.
Power up to stock (1.2), plug into pc.
Transfer pictures, documents, etc.. to emmc memory space.
Disconnect from pc, power down.
Insert SD, power up to Android.
Use new (to device) data as needed.
YMMV

The eMMC storage is an additional storage. You can do whatever you want.
And yes, copy/move/drag/paste files/folders, pictures, clips, docs, whatever.
Actually...I figured out that I can move or remove anything in and out of the emmc with Root Explorer. No USB required. Except of course u need to import an external file which I think that's what u thought I meant ....can't believe what a useful tool root explorer is! definitley worth the 4 bucks...

Running off the emmc...I almost ran of micro like u...but that's kinda cool that u can take out ur SD and go back to stock for the day if wanted...I do miss the children's books feature. But I flashed already and I can just buy kids interactive books off the market...they are cheaper than b&n anyways...thanks.
Hi All,
I've searched the forums and I'm unable to find a resolution to my problem.
I'm having horribly slow transfer speeds from the computer to my Atrix internal SD card. I am transferring about 7GB of music from my 64-bit Win7 PC and status says about 4-hours. Used to only take a few minutes on my Captivate.
I've tried formatting the internal card, re-flashing back to stock, different USB ports on the PC, etc all without any luck.
Any ideas before I completely tear my hair out?
Thanks in advance.
EDIT: When the internal SD gets mounted, Windows is slow to find the drive and list its contents. The 2GB external that I have in the phone comes right up.
Wow. No idea. Iwas quite surprised at how fast toshiba emmc is. What speeds are you getting btw? Oh, i do know one thing possibly. Do you transfer files a lot? Flash memory has a limited life, though many of us never see flash die or start to die. But if you do these types large file tansfers, 7gb often, youre using up write cycles much quicker. Also, the folder youre transferring to is about 12 gigs right? Say you have 4 gigs of stuff in their already, and youre trying to put 7 gigs in, more than likely youre transfer speed will be slowed down. You need space to actually to fill stuff up, and the more space, the faster you can fill it up. I wish i could be a little more detailed. I know about this from solid state drives, and the concept is basically the same, but works a little different. I dont know if that is your problem though.
I voided my warranty.

Take the SD card out of the phone and put in the adapter. Try measuring speeds via adapter. Your SC card might be dying.
His internal card.

Just thought I'd throw this out there, when you format an SD card it asks you for the amount of "bits" you want to format it with. I would research which number is best suited for your particular SD card depending on how big it is. Cause the standard number it automatically inserts may not be the best.
edit: ignore post. For some reason when I read it, my eyes saw external SD card instead of internal. Derp and Derp.
Which of the four (well, three) USB modes are you using to do the transfer?
So, considering that 6.0 can format the sdcard to appear as internal memory, is there any good reason for going with 32GB or more? I would like to save the money and just get the 16GB and format the card so it appears internal.
Other than being slightly slower than internal memory, would this be a valid route going 16+card as opposed to 32+card?
I have a OnePlus One right now with the 64 and usually have about 20GB left so 32 is the base I need but I figure I might be able to get away with 16 if the card appears as all internal anyway.
Thoughts?
Yes, I went with a 16GB model also for the same reason. I installed a 64gb Sandisk extreme SD card that transfers up to 90mb/s. Nandroid backups went from 30 minutes on my old SD card (some cheap crap) to less than one minute. With a proper card you'll have no issues running apps off the SD.
The internal memory isn't much faster.
I've been considering using the adoptive storage, but I went ahead and bought the 32gb. Call me old fashioned, but I like having an SD card that is considered separate from the main storage for one big reason: If I ever have to do a wipe of the phone, I know that my photos, TWRP backups, and so on, are all safe as long as they are on the SD card. I don't know if we know what'll happen if you use the adoptive storage and you have to wipe the phone. Will it keep what is on the SD card part? Will it wipe it as well? My understanding is that it'll wipe it.
So I may just keep on doing what I'm doing... change the camera settings to use the SD card for pictures and videos, make the SD card the default place to save downloads, and only use the internal storage for app installs.
I use my SD card to store all of my media and reserve internal storage purely for apps. I can manage with 16gb since I don't have a lot of big apps. Adoptive storage is a nice feature but I don't think I'll be using it, since I like taking my microsd out and popping it in my laptop to manage my music, photos and movies.
Do we know FOR SURE that there will be no way to partition the external SD so that part of it is used for the OS (non-readable outside the phone) and part for external storage?

I haven't read anything that would suggest so. Everything I've read indicates that it formats the entire card to be used as internal storage. The tradeoff, it seems, for allowing adoptive storage is to make it very difficult for your to remove the card and use it in another machine.
Well thanks guys. Still up in the air which phone I'll ultimately get and if it's the Moto, what size but this does clarify things.

If you format the card as adoptive storage you can't just pop out the card and read it from a computer. The computer won't be able to read it.
