1.96GB option now available

Done!

http://www.mailpen.com/download/repartition2GBdata-v1.zip for the repartitioning; the http://www.mailpen.com/download/reformatData-v1.zip remains the same. Same procedure, of course.

I call it 2GB in the filename, but it's 1.96GB, just as the original B&N "1GB" size is actually 0.93GB.
[Nook Color General] themerchant:
thanks again Dean. :)

couldnt be easier!! just follow his instructions. (didnt have to re-register)

my NC is showing 5.23GB free on the device info page after a stock restore ... off to do a emmc flash :D
[Nook Color General] themerchant:
just got done doing eyeballers guide http://xdaforums.com/showthread.php?t=1030227

all works great!
[Nook Color General] xdavisitor:
Thank you all for clarifying and verifying. Dean, your 1.96G data partitioning is the direction I intend to go (from the latest version of Nook) since it the most flexible and provides some of the benefits of both the stock partitionings. Much to do and learn . . .:)
[Nook Color General] hungryTux:
This may come across as a total noob question..but I was able to sideload more than 1GB of videos/mp3s on my new Nook Color's internal memory. That's a clear indication that mine's got the older partitions right?

Again, sorry for the noob question.
[Nook Color General] DeanGibson:
Counting past 1GB

Yes, assuming all the files are still there ;)
[Nook Color General] themerchant:
This thread really needs to be pinned.

Still running strong on the new resized partions on my blue sticker Nook :cool:
[Nook Color General] tinymiata:
1.96Gb data partition please.

I would love a to set mine like that. for max back up storage.

I have the new 2011 BN partition set up.

Thanks.

[Nook Color General] kan555:
Got my nook today with Blue sticker. I repartitioned using the 2 GB one and put CM7 on it. However, my nook randomly reboots itself every 2-5 minutes. I can only get it to reboot when I plugged in the charger. So, I'm thinking to return or exchange. I need it back to stock. How can I repartition it to 5GB/Data and 1GB/media? Please please help. Thanks a million!
[Nook Color General] DeanGibson:
Back to the future

For the repartitioning step in the original post, use:

http://www.mailpen.com/download/repartition5GBdata-v1.zip

Then do the reformat as well, as described in the original post.
[Nook Color General] ramiss:
Agreed. Please sticky!
[Nook Color General] Zoho7:
Hell! This is just FANTASTIC! Thanks a MILLION!!! I've been frustrated with this issue since I got my replacement. Everything just works like a charm!!! I've got everything back now! Thank you so much, DeanGibson! :D
[Nook Color General] tinymiata:
Awesome used the custom and CM7 sees it perfect.

Thank You!!!
[Nook Color General] rogermusa:
DeanGibson, you sir, are an absolute...genious. Your files work beautifully. After following your steps to the letter, I now have a blue-dotted Nook Color running CM7 flawlessly.

Much obliged.

This solved my .92gb storage issue after NC HC3.0

Not sure if this was the "right" way to fix the problem but it worked.

[Nook Color General] christoophat:
I bought a used NC a few weeks ago, so no external packaging included. Under Device Info, it lists that I have 5GB of storage, so this means that I have the "old" (1GB data/5 GB storage)

partition system, yes?

Thanks for all the great info & help here!
[Nook Color General] siskiou:
Could someone please tell me if I can accomplish all this with one 2GB micro sd card?

First I have to create a bootable CWM sd, use it to boot the NC, then take it out and use same card to do the re-partitioning, then use same card to put CM7 on emmc?

And if I need to reverse everything for warranty reasons, it can be done with one sd card, too?

Just want to make sure I'm not making some cardinal mistake, before I start. Am very, very new at this, and have read so much that I'm starting to go cross-eyed. ;)

My NC is a blue dot with 1.2 and the new partition scheme.
[Nook Color General] pdagenius:
My understanding is that you are correct, but haven't got my Nook yet - next few days. You need a SD card in the Nook to boot CM7. Maybe this needs to be reformatted if you're using the same one for CWM.
[Nook Color General] goldiefish:
Excellent work Dean. I love this community.
[Nook Color General] akenis:
Got CM7 on eemc, but buggy. And CWM freezes and won't clear my data. From settings screen I see this:

Internal storage total 5.09 GB

Additional /mnt/eemc 1 GB

How does that relate to "data" and "media"?

Is this old partition or new partition?

I bought yesterday, and turned down a box with a blue sticker. She said they just found a stack of these with no sticker.
[Nook Color General] akenis:
Well thanks for the noob help! Some idiot forgot the blue dot I guess. Did repartition:

Internal storage total .92 GB

Additional /mnt/eemc 5.23 GB

So Data = Internal

Media = /mnt/eemc

CM7 makes a bunch more sense with the status bar and menu available!
[Nook Color General] Zephyr757:
Dean, I just wanted to say thank you so much for doing this for the community! You've saved a lot of us from having to figure this out ourselves or having otherwise limited hardware! True awesome sauce flows within your veins, kind sir!
[Nook Color General] WobbleTheHutt:
I personally would love for a custom partition layout with an even smaller media or NO media partition as its wasted space under CM7 ^.^ If it wont break anything
[Nook Color General] sqs1shu:
Not sure why some folks says CM7 is useless for media partition. CM7 can mount media partition a long time ago. I have music on nook color media partition and sdcard and can play them without any problem.
[Nook Color General] siskiou:
Yes! Thank you!

The manager at the local B&N had promised he could reverse the blue dot partition, but then found out he couldn't, but my blue dot is now repartitioned and it couldn't have been easier.

I'm extremely grateful!
[Nook Color General] kan555:
I read somewhere that said CM7/86 supports new partition scheme so I didn't repartition it and flashed CM7 on it. I ran into lots of problems (can log in to Market but couldn't download anything, process.media Force Close every 5 seconds, bottom menu was not displayed, etc) So, I tried the custom 2GB partition then put CM7/88 back on. All problems are gone. I have a nice solid tablet for my kids to play now. DeanGibson .. Thanks you so much again for your wonderful contribution.
[Nook Color General] jtxmobile:
Thank you for this!!!!
[Nook Color General] Chahk:
But I already have an 8GB SD Card that I use for music and books and videos and the rest. The 1GB space for apps, on the other hand is quickly disappearing, especially once 70MB+ games like Plants Vs. Zombies get to be the new standard. With 75 apps the internal memory on my NC is already at 600MB used. Granted, I haven't moved any apps to SD Card, but that's because I'd like to be able to freely unmount and remove it without losing access to any of the apps.
[Nook Color General] kan555:
Now that I have my blue sticker Nook setup with the custom 2GB and CM7/88 installed perfectly. I want to do the same for my regular nook since it's down to 100 mb of space. I want to repartition using the 2 GB. What's the easiest way to do this? Do I have to wipe and redo the entire system? TIA.
[Nook Color General] TabletConnect:
I did the repartition install via CWR 3.0.2.8. After installing and rebooting, I received messages that" E: Can't Mount /cache/recovery/command; E: Can't Mount /cashe recovery/log; E: Can't Open/cache/recovery/log; E: Can't Mount /cache/recovery/last_log; E: Can't Open/cache/recovery/last_log".

Is this normal? Thanks. I don't want to install the second piece if it is not.
[Nook Color General] Chahk:
This is normal because the /cache partition has not been formatted yet. The "second piece" as you call it will fix this problem.
[Nook Color General] pakesack:
I opened Rom Manager today, and it says there is a new version of CWM (3.2.0.1). Does anyone know if this fixes the problem of not being able to have a data partition greater than 2GB?

EDIT... nm i found this in the CWM thread:

3.2.0.0 - Support for newer nooks with the 5G /data parition! New .32 kernel is included which fixes the freezing after formatting /data! (/data format issues. Don't Use)

3.2.0.1 - Fixes a bug with 3.2.0.0 (actually a build issue) where ext3 (/data and /cache) wouldn't be formatted properly (they were but CWM was bombing out)

*Recommended *
[Nook Color General] BitingChaos:
/mnt/emmc has been empty on my Nook since day 1.

/data fills up pretty quick. The 5 Gig /data and 1 Gig /mnt/emmc seems to make the most sense.

With 8 Gig and 16 Gig SD cards being so cheap, the internal space would be best used on /data.

What are the biggest issues if we start messing with partitions?
[Nook Color General] DeanGibson:
CWR 3.2.0.1 supports large /data partitions ...

I was wondering that as well when I noticed the CWR update to 3.2.0.1 showed up in RomManager. Thanks for the update! I will wait a couple days for confirmed reports, and then edit the original post to reflect the change.
[Nook Color General] pakesack:
CWR 3.2.0.1 seems to have fixed the partition bug. I repartitioned back to 5GB+ data, rebooted, formatted, then reflashed Phiremod 6.3. Everything is working great and the 5GB data shows up under settings. dont forget to reboot after the repartition. i forgot to, and wasnt seeing the 5GB data at first.
[Nook Color General] martian21:
So now that CWR 3.2.0.1 supports partitions larger than 2GB, is there any reason not to go with a 5GB data partition? (other than the warning in rule #5)

My Nook has the old 1.1 partitioning scheme and I've pretty much used all of my 1 GB /data partition so I'm at the point where I either need to start removing apps or transferring them to the SD card (which I don't want to do since I sometimes swap SD cards).

I assume the re-partitioning is destructive. Has anyone successfully restored a nandroid backup after re-partitioning with CWR 3.2.0.1? I don't mind starting from scratch but would be nice if I didn't have too.

Crazy idea: Other than probably breaking compatibility with stock ROMs and future B&N updates, couldn't you go so far as to make /data 5.9 GB and /media just a few MB? Or could you even do away with /Media all together if you only plan to run CM7?
[Nook Color General] hockeyfamily737:
I did successfully restore a nandroid after repartioning. I flashed CWM, did a nand. Then I repartitioned and restored a completely different backup...in that order.
[Nook Color General] DeanGibson:
More ideas

Although many on the B&N forum complain about the new B&N partitioning, I think it's the best solution for most people, once you can backup and restore (which 3.2.0.1 apparently gives you) the /data partition.

Partitioning is destructive, but the restore is "partition-ignorant", so if you have a restore that fits the new partitioning, go for it!

Yes, I could create a 5.9GB/0.1GB partitioning. However, I'd be suspect of leaving off the /media partition altogether: I don't run CM7, so I don't know if it tries to mount the /media partition or not.
[Nook Color General] martian21:
Thanks for the reply! I think you have pretty much confirmed my thoughts. Also, from reading you posts on your initial work with re-partitioning it looks like (so long as you know your way around fdisk) you can recover from just about anything partition wise. It's nice that both /data and /media are in the extended block so that you don't have to mess with the primary partitions.

I'm fairly certain that the stock ROM won't take to kindly to having the /media partition removed since it expects it to be present and uses it but from what I can tell CM7 mounts it but doesn't do anything further with it so I'm guessing CM7 won't complain to loudly if it isn't there.

Before I get to wild and crazy with fdisk though, can someone confirm what partition the Serial Number and MAC address information is stored in? I'm fairly certain it isn't in /data since I frequently format it and I can't imagine they put it in media but I'm not certain on that one.

EDIT2: Based on the info from DeanGibson it appears that Op1, Op2, and Op3 should not be touched. Per Dean's information Op1 is boot (don't want to lose this partition), Op2 contains your S/N and MAC address information (again, don't want to lose that), Op3 contains the B&N recovery image (which probably isn't vital seeing as we have CWM .zips that can restore stock but probably not worth the risk of deleting)

[Nook Color General] sicily123:
So, if i'm going to use phiremod 6.3 and im going to put my music, vids, etc. on my sd card, which formatting should I choose? Sorry for the noobish question and thanks for the help.
[Nook Color General] DeanGibson:
The boot partition is 0p1 (FAT32).

The MAC address & serial # is in 0p2 (FAT32).

The B&N recovery image is in 0p3 (ext2).
[Nook Color General] martian21:
That's exactly what I needed. Thanks!

Looks like my strategy of not messing with the Primary partitions is spot on. I think I'm going to try blowing away the /media partition and see what CM7 has to say about it. I can always re-partition if I need to go back to stock.
[Nook Color General] akenis:
Sounds interesting!... still not sure what use the mnt/SD 5gb does on my cm7. Can u store data on it as if it where an SD card? Never tried running without an actual SD card..or a full one.
[Nook Color General] martian21:
I've been putting my music and videos on it. Presently that is about all it's good for since I don't believe you can move apps to it (at least not without some hackery)
[Nook Color General] kristoff1313:
dual boot

that is why for me... plus enough apps to fill 1gb..

and huge thanks to Dean making this so simple now
[Nook Color General] martian21:
Deleting mmcblk0p8 (media) on CM7 works!

Tonight I was able to completely remove the mmcblk0p8 (media) partition and use the extra space for a larger mmcblk0p6 (data) partition.

My /data partition is now ~6.2 GB!

WARNING - If you do this there is a good chance stock B&N ROMs will NOT boot!!!

I performed a full nandroid backup before partitioning. I then re-partitioned, loosely following DeanGibson's post here, with the obvious modifications that mmcblk0p6 (data) is larger and I did not re-create an mmcblk0p8 (emmc) partition. I was then able to perform an advanced restore of the /data partition and CM7 booted right up like nothing had changed!

A quick look in Root Explorer shows that /mnt/emmc is

not

mounted and /emmc is just an empty folder now.

EDIT: CM7 did eventually complain in the status bar about my SDcard being damaged (referring to the missing mmcblk0p8 partition). This was quickly fixed by commenting out the last line in /system/etc/vold.fstab

#dev_mount emmc /mnt/emmc 8 /devices/platform/mmci-omap-hs.1/mmc_host/mmc0

Under Settings>Storage>Additional Storage you can still see /mnt/emmc however it is listed as "unavailable".

My new partition table is as follow:

Disk /dev/block/mmcblk0: 7944 MB, 7944011776 bytes
255 heads, 63 sectors/track, 965 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/block/mmcblk0p1 * 1 9 72261 c Win95 FAT32 (LBA)	/boot
/dev/block/mmcblk0p2 10 18 72292+ c Win95 FAT32 (LBA)	(MAC & S/N)
/dev/block/mmcblk0p3 19 56 305235 83 Linux	(B&N Recovery)
/dev/block/mmcblk0p4 57 935 7060567+ 5 Extended
/dev/block/mmcblk0p5 57 114 465853+ 83 Linux	/system
/dev/block/mmcblk0p6 115 890 6233188 83 Linux	/data
/dev/block/mmcblk0p7 891 935 361431 83 Linux	/cache

Reviewing the above table you can see that my Nook has 965 cylinders however the extended partition does not extend out to the final cylinder (965), if stops at 935! I have no idea why my Nook has a different extended partition size than DeanGibson's.

I'm certain that, using fdisk, I could delete mmcblk0p5 (system) and mmcblk0p4 (extended) and re-create mmcblk0p4 (extended) to end at cylinder 965 instead of 935 and then also re-create and formate mmcblk0p5 (system) and then restored /system in the CWM advanced menu but I decided that it probably wasn't worth the extra effort at this point for ~241 extra Megabytes.

I am however really curious as to why my extended partition appears to be smaller??? My Nook was

not

a new "blue dot" Nook however it did come pre-loaded with 1.2 (read forever). (My S/N is 201044000793xxxx)

It appears that the last 30 cylinders are just un-partitioned space and I'm really tempted to "re-claim" that space. I just wish I knew why it's different.

Any ideas?

[Nook Color General] DeanGibson:
Size is everything

For a while (until I did my own) I used the "dual boot" partitioning in http://xdaforums.com/showthread.php?t=959461 and I noticed that his partitioning also ended at 935. My 0p4 ended at 965, but not his partitioning. Your 0p4 ends at 935, but fdisk reports that you have 965 cylinders. Perhaps there was a previous memory chip that limited things to 935? Did you run any other software that did repartitioning (perhaps a CM7 install) without telling you? I have no familiarity with CM7 so I don't know what it does.
[Nook Color General] martian21:
I've not knowingly done any re-partitioning before last night. I've also not dual booted at all. I suppose it's possible that the CM7 install does some re-partitioning but I find it pretty hard to believe. With so many CM7 users any re-partitioning would be well documented.

I'm pretty certain it came 935 from Barnes & Noble. Would be nice if others could fire up terminal or ADB and run busybox fdisk -l /dev/block/mccblk0 and report the size of their extended partition.

Perhaps I stumbled on another subtle change B&N threw in there? Only thing I can think of is that B&N is somehow storing some kind of data outside the partition table although i'm not exactly sure how that would work or, as you stated, they have a second source memory chip that is slightly smaller and chose to use a single partition table for both chips.
[Nook Color General] WobbleTheHutt:
any chance I could get a flash-able zip with this partition layout? :)
[Nook Color General] DeanGibson:
Size is everything

Well, both of my NCs have 965 cylinders. One of my NCs was first registered on Jan 19 by the original owner, so that's a fairly early unit, and it has 965.

Note however, that I had both units repartitioned at a B&N store to the new layout. The older one I obtained more recently, and I had it repartitioned by B&N as soon as I bought it (at a pawn shop for $150, with B&N cover and extended warranty!), so I don't know what the partitioning was before hand.

I'm not certain, but I think I looked at the partitioning of my first unit (of more recent manufacture), and I think it had 965 as well. However, I'm not sure.

Note that my procedures in the zip files don't change the size of 0p4, and just allocate /media to fit in the last portion, after /data and /cache have been allocated.
[Nook Color General] DeanGibson:
Options ...

Message out of order; quote from next message in sequence:

That's my reasoning as well.
[Nook Color General] martian21:
That will be entirely up to DeanGibson, he is the master of flashable zips. I just like to have fun with fdisk. Honestly, even if I could I don't think I would want to put my partition table into a flashable zip since it removes one of the stock partitions which would no doubt lead to many issues for people who flash stuff without reading.

Those comfortable with ABD and fdisk should be able to recreate what I did fairly easily. Otherwise I would recommend flashing the 1.2 partition scheme. it's only about 800 MB shy of of what I have for a data partition with no side effects.
[Nook Color General] Mark_OB1:
Dean, based on your post on May14, in the initial discussions, where you were educating folks,

[link to bookclubs-dot-barnesandnoble-dot-com\t5\NOOK-Color-General-Discussion\Major-and-potentially-ugly-Change-to-the-NOOKcolor\m-p\1023444#M44322 removed, due to too few posts here.]

it looks like you had the smaller 935 endpoint on that unit.

- Mark
[Nook Color General] DeanGibson:
Size is everything

Ah, interesting. While the 0p8 end-value had probably been modified by my usage of internal dual-boot, almost certainly the 0p4 end-value had not. So, apparently the B&N in-store repartitioning reset the size of 0p4 to give back the 30 unused cylinders (250MB). Unfortunately in my linked post (above) I did not include the fdisk header, where fdisk reports the total device size, irrespective of partitioning.

So see, here we were all fussing about the new partitioning, and B&N gives us 30 more cylinders! Sounds like a reason for users to go into B&N stores to get the additional space, and then come back here to get the actual repartitioning they want. I'd do another install .zip file to do it, except I'm not fond of deleting the /system partition on a user's unit. Perhaps if I made the instructions perfectly clear that users had to have a CWR backup before the install ... I'll think about it. It's also possible (but very unlikely) that B&N had something secret in that 250MB...
[Nook Color General] martian21:
While I will almost certainly re-partition my Nook to claim the extra 30 cylinders, I would be VERY hesitant to put together a tool that blows away the system partition on other user's Nooks for a mere 250 MB. It's just not worth the dozens of "OMG my Nook doesn't boot now" posts.

A compromise might be to post the manual steps to delete the partitions, with the applicable bold red letter warnings, and then automate re-creating the partitions.
[Nook Color General] quepaso:
Im still on the 1/5 original nook setup and was about to change it to 1.9/whatevers left, but if you are going to update the tool i would like to wait and get the whole meal deal.
[Nook Color General] DeanGibson:
Undecided

I haven't decided yet and won't for a few days. If I do a tool to recover the 250MB, it should be very easy to just restore a CWR backup afterwards.
[Nook Color General] martian21:
Assuming you have a CWR backup :eek:
[Nook Color General] DeanGibson:
Untested ...

If not, a CWR "factory reset" should restore the installed B&N image from the recovery partition. I have not tested that in CWR, however.
[Nook Color General] martian21:
I reclaimed my missing 30 cylinders tonight. I'm now using all 965 instead of just 935. Didn't have any issues.

Thanks for reply, hockey but can you pls elaborate it a little bit, I'm kind of slow here.

So you said, the NC has 8GB internal memory, 2GB will be reserved for the ROM (really? takes 2 GB for the bootloader?), the 6GB left will be split as 5GB /data and 1GB /media (referred to Stock ROM)? Am I right?
