Sd card cannot be accessed by laptop - Nook Color Q&A, Help & Troubleshooting

Much help would be appreciated. Total new experience for me.
I have cm7 stable on sd of my nook color. I have everything up and running great. trying to overclock and when I take my sd card out of nook and put into laptop, it asks me to format it. It is not allowing me to copy the kernal to my sd card. Is there another way of doing this?
While inserted in my laptop, I look at the properties of the sd card and it is showing to be in raw format.
any help would be greatly appreciated.

Are you unmounting the SD card before you eject it? Also, are you sure the FS on your SD is FAT32?

When I originally formatted the card before I burned the installer and the cm file on the card it was formatted to a fat16.
I have not unmounted the card prior to ejecting. I will give that a try.

okay I unmounted before ejecting... put into laptop and the laptop is still wanting to format the card.
when I look at the properties it says file system is raw, and storage space is 0mb.

Maybe your card reader couldn't read microSDHC card?

With CM7 running off a uSD which I am doing as well, some built in laptop readers will not read the uSD but it may be read with a USB reader. But, it will typically only read the 1st partition which is the Boot partition (unless you use a program to set the 4th partition as primary and active).
To access the 4th partition for storage, you can try to connect the Nook by USB cable to your computer and enable USB storage mode. That should connect you to the 4th partition and your internal mmc storage partition too.
If not, download and use the following app:
http://forum.xda-developers.com/showthread.php?t=952456
The app is a little deceiving, you have to scroll in the app to see the "Confirm" button when you are mounting, and unmounting.

Thank you!!! I'm going to try that tomorrow.

If you still have stock on eMMC, boot with the card out, then insert it before the stock OS fully loads (like on "n" or "Nook Color" splash screens). The NC will mount the boot partition as storage; there should be an SD-icon notification in the lower left, and if you tap it, it should say "SD card inserted." You can then connect via USB, and hopefully your card and PC will kiss and make up.
ETA: I've had no luck inserting the card after the OS is fully loaded--it just reads "SD safe to remove."

That worked!!! Thank you very much!!!

SD card Upgrade problems

My apologies is this has been posted before. I am trying to upgrade the sd card in my phone (MT3G), using theunlockr.com instructions found here:
http://theunlockr.com/2009/10/15/ho...-android-when-using-swap-hero-and-or-apps2sd/
So here is my problem. I put the new card in the phone and follow the instructions. But when it’s time for me to connect the new card to my PC, my PC will not read the card unless I format the card first (FAT32 is the only format option it gives me). I get this same error when plugging the card into the PC or using the mass storage option from the phone’s recovery screen. So I chose to format the card so the PC would see it and I could load the ROM back on to it. Now the phone does not want to mount the sd card.
So I start over again. I plug the new sd card into the phone and wipe, partition with no problems. But when it’s time to convert ext2 to ext3 I get this error : “run update_fs via consel”. What does this mean and how do I accomplish this?
How do I get the sd card to be readable from both the phone and the PC?
Thank You

[Q] Dumb CM7 Rooting problem

Hi, I have a nook color and an 8gb SD card. I've followed the posts to get winimage to write the generic-sdcard-v1.3.img written to my card and installed on my nook. However, when I shutdown the nook and put the SD back in my PC, there is no \Boot partition, and windows(xp) says the card is not formatted. What on earth am I doing wrong??
Thanks.

Put it back in the Nook after you have booted into CM7 and format it with the Nook. If you have a camera that takes micro SDHC cards you can probably format it with that as well but will probably want to delete any folders the camera creates later.
Well of course! How stupid am I?? Jeesh! THanks.
OK maybe I'm just missing something big.
After I install the SD card in the Nook with the CM7 upadate on it, the SDCard is modified such that when I remove it, the PC no longer recognizes the format. I get the card in my list of drives, but when selected it says "not formatted" If I choose format, it wipes the card and I can't boot to CM7 from it any more. I can't find a format option on the Bare CM7 image - just erase SD card -which still leaves it in a format that the PC can'd read to put the gapps on.
help??
Logical thinking, dr. wambo.
you have drive C which you install Windows OS on it, and then you format it, what do you expect?
In your case, "boot" MUST be there in order to work, if you format the card, it's gone for good. Question is why you format it after creating it?

Understood. My issue is that after I put the SD card into the Nook and boot the nook, it apparently reformats the SD card such that when I put it back in the PC, I can SEE that the card exists, but no files on it. If I check properties, it shows no free space on the disk (and none used for that matter.) So, I am unable to copy the gapps-gb-20110613-signed.zip file to the SD and restart the nook.
See?
A simple question, do you see the "boot" when your plug the card into your PC (running Windows)?

I do not. Windows explorer shows an SD card in the list, but when selected, it says the card is not formatted.
Card seems to boot fine in the Nook. I must be doing something really dumb. I was able to install honyecomb successfully using this card, but wanted the functionality of CM7. Darn, this just shouldn't be that hard.
Wait, if the card still "seems to boot fine in the Nook" then it means the "boot" is still there, it just Windows not seeing it.
On PC side, try to insertion and removal a few times and see what happens.
If completely nothing, switch to other Windows PC OR if you have the USB-SD adapter, use it.

I should mention that the nook boots fine off the card provided I don't Format it in the Windows box.
Have removed and reinserted the card multiple times into the Win (xp) box. No Joy. Tried a different machine and got exactly the same results.
This just can't be that hard!!
Are you using Windows PC or Linux?
Worst case, reinstall
Windows PC running. XP sp2. ADDITIONAL NOTE. After I winimage the SD card with the generic image, I do indeed have a \root partition. Once I insert it in the Nook and let it boot, shutdown, and I reboot, CM7 is installed and running from the card, but when I put it in the PC, the \root partition is no longer there.
Additional info. I've now tried this on 2 different SD cards and they both do the same thing.
Not sure if you're still having problems, but it's normal for Windows not to be able read the entire SD card after it's been imaged for CM7. There are I believe 4 partitions and it will generally only see the 1st (/boot). Additionally, it will sometimes only read correctly when using a USB card reader, rather than putting the uSD card into a built-in card reader in your PC (not sure why). Hope this helps.
Interesting...perhaps that's the problem. I'm using the internal SD reader on my laptop. I'll run out and get a USB reader and see if that helps.
THanks.

[Q] Access to bootable sd card from stock OS after 1.4.1 update

I have a nook color with dual boot from sd card. The sd card having an android 3.0 version.
After I got the 1.4.1 update, I noticed that I was able to access the sd card( the boot partition alone) from the stock OS boot of nook.
But now, dont know how, I dont see that anymore.
Was this a flawed update that was fixed or am I missing something.
Do help please.
I could really use the advantage of using the bootable sd card as a regular storage card when using the stock OS of nook. I prefer reading on the stock OS of nook.
Not sure why you're not seeing the SD card anymore, does it still boot?
SD card installs create multiple partitions on the SD card and the Nook will only be able to access the first one (boot). It should be accessible with any version of the Nook default OS.
You should have a media partition with a decent amount of room (1-5gb depending on NC version). That would give you more room than the 100-or-so mb on the boot partition.
Just found out that you can point the emmc install to see the "sdcard" partition of the sd card using the following info:

Yes, I can boot from it. Every time I plug in the SD card, the notification already says that it is safe to remove the SD card. In the device Info part of the setting, the "Unmount SD card" is already greyed, though it does say that the SD card is found.
It is however useful for me to know that the boot partition should always be accessible.
I did remove the SD card a couple of times without unmounting it first, could this possibly have corrupted the card?

Try to boot the uSD card (the one with Android 3.0 on it) and see what happens.
If it can, then it's good, if not, you can say it's corrupted.
Yes, I can boot from it. So I assume the card is OK
I plugged in other uSD cards and they get recognized fine. So I assume the Nook stock OS device recognition is OK.
I should probably recreate the boot partition as a last ditch effort
I had the same problem at first, but now I have mounted the correct sdcard partition that I wanted to mount.
I couldn't get it to work with editing the vold.fstab file at first. Then at some point after I manually mounted the correct partition through adb shell and edited the vold.fstab it now works.

defy + sd card problem

I have accidentally formatted my SD card in ext3 file system mode and now my phone cannot read it.Even when i connect the phone to the computer in usb memory card mode...the sd card is not shown in the computer. So i am not being able to format it again.Please tell me how to reformat it back to fat32 ....
Use EASEUS Partition Master, it will read your SD card in EXT3 format and will allow you to manage / format it!
open disk management (start->run->diskmgmt.msc) and erase your ext3 partition (doable in windows)
If you have any trouble doing this while the card is in your phone, you can also remove it and use an USB Card Reader.
But as said before, you just have to change the unit type to get it working again.
Good luck.

You can use a USB Card reader and this software: "hp disk storage format tool".

[Q] SD card partition problem

So I am running CM7 off of an sd card in my nook color.(Using http://forum.xda-developers.com/showthread.php?t=1904129 and I highly recommend). Win32discimager for some reason created a small partition just larger than the installer which remains on the card. I also have the android OS on the card that is taking up 1 gb partition. The rest of my 16gb micro sd card is labeled as the emmc for the tablet which is not what i intended. Now I cant load it up with my movies and videos like I had hoped.
Does anyone know:
Is there any way I can change these partitions on my card? (I have already tried EasuUS partition manager)
Where did the 1gb partition that android is on come from and why did the emmc get so large?
Is there any way to take the android image currently on my sd card and just putting onto the nook after I have already had it run from the sd card and then just formatting my sd card for storage?
There are probably newbie questions but I have tried to do my own research and havent found any certainties. Any help would be really appreciated.

Ok, first you need to go to my tips thread linked in my signature and read in section B how the verygreen SD works. You will understand the partition structure a little better.
Now for your sdcard/emmc media storage problem, you have a setting wrong in CM7. Go to settings, CyanogenMod settings, Application and uncheck "Use internal storage". What that setting does is swap emmc and sdcard so that your real sdcard is called emmc and internal media storage is called sdcard. It is not default that way. Somehow it got checked.
