If I were to create a 1.5gb fakesd.img ext2 file
done once, on computer
dd if=/dev/zero of=fakesd.img bs=1048576 count=1536
mke2fs -F fakesd.img
--------
done in rootfs-init
losetup /dev/block/loop2 /sdcard/fakesd.img
mount -t ext2 -o noatime,nodiratime /dev/block/loop2 /fakesd
change " symlink /mnt/sdcard /sdcard/ " in rootfs-init.rc
symlink /mnt/sdcard /fakesd/
probably want to avoid changing the external path from /mnt/sdcard/ to anything.. for compatibility sake..
I have my windows stuff on my card. I want android to index as little as possible yet still be able to access my sd card at /sdcard.. Will this work?
I have a feeling that someone is just going to tell me to partition card. I don't feel like it right now..
Partition the card Just kidding, but I like your thinking.
Trying to test it out post boot.. My router has more command line functionality, thanks Google.
hi
I have two 8GB class4 memory card but when I'm just a partition're doing very bad work
Android is reset
apps are broken
High and low speed is
And ...
But when a 2GB partition, I just work very well
Benchmarking partition is much better!
no more problem in android!
So I decided two partitions 2 and 6 GB and the second partition so I just do mount
Method:
1- Memory partitioning (first partition 2gb fat32)
2- copy android in first partition & run it
3- in android terminal type:
Code:
ls /dev/block/m*
or adb
Code:
adb shell ls /dev/block/m*
result like this:
Code:
/dev/block/mmcblk0
/dev/block/mmcblk0p1
/dev/block/mmcblk0p2
/dev/block/mmcblk0p3
Partition testing can be yours for the mount
1- make a folder (not in /sdcard & /mnt/sdcard)
Code:
mkdir /mnt/sd2
now test (for fat32): (just change mmcblk0p2)
Code:
mount -t vfat -o fmask=0000,dmask=0000,rw,flush,noatime,nodiratime /dev/block/mmcblk0p2 /mnt/sd2
(for ext2)
Code:
mount -t ext2 -o noatime,nodiratime /dev/block/mmcblk0p2 /mnt/sd2
Now the partition should be on the /mnt/sd2 mounted
and you can mount in boot
backup /init
open init and past mount cammand below this line :
Code:
PATH=/sbin:/system/sbin:/system/bin:/bin:/system/xbin:/system/xbin/bb:/data/local/bin
now we have auto mount partition
but we have one problem! we should link /mnt/sd2 > /mnt/sdcard
Who s the solution?
interesting idea. will try out.
Android Batch File to Partition SD Card
This batch command file invokes the /sbin/parted and /sbin/tune2fs tools hosted by ClockWorkMod (CWM) Recovery 5.0.2.0 to control partitioning of your SD card for a variety of purposes, some of which are listed below.
It is a good idea to review the command line options and parameters of the parted and tune2fs tools: On your phone (for example, via computer-enabled ADB or terminal emulator), get root and enter:
# /sbin/parted --help
# /sbin/tune2fs --help
I decided to make this a separate thread for a number of reasons:
Streamline the process of making room for second ROM in a dual boot configuration (see http://forum.xda-developers.com/showthread.php?t=1651356 ). These commands can theoretically be rolled into a flashable zip to almost fully automate a dual-boot install of fixed ROMs, e.g. CM9 and CM7.
My Dual Boot threads have “sensory overload” written all over them
The amount of material presented here is probably enough to warrant a separate thread
This is an Android-friendly alternative to GParted/MiniTool. For example there is no need to pull SD card, partition and reinsert. Of course, GParted has the pleasant GUI and gives you a chance to review your changes before committing, whereas the Android “parted” tool is highly utilitarian.
Batch commands are quickly and easily modified to create/remove/adjust partitions. The general consensus is that for large files, ext3 R/W speeds are faster than those of FAT32. And ext3[4] is more stable and can handle files exceeding the maximum 4GB allowed by FAT32.
Batch commands are easily modified to perform customizations other than dual boot
Some users may wish to host their entire system on SD card: ROM, music, pictures, movies etc.
Some users may wish to return their SD cards to a traditional single-boot state by running a subset of these batch commands
That said, I strongly advise that you NOT run these commands UNLESS you are comfortable with ALL of the following:
1. /sdcard (FAT32) and ALL subdirectories copied to /emmc/sdcard-backup. Ask yourself: Do I have enough space left on my 10GB emmc partition to host a full backup of /sdcard? AND, will there be enough room on the /sdcard filesystem to restore this backup AFTER downsizing my SD card's FAT32 partition?
2. Any existing ext* partitions of SD card are blown away, for example those generated by a previous dual boot zip install. In other words, you lose /system, /cache and /data from an existing sdcard-based ROM.
3. You MAY lose all data on your (backed-up) FAT32 partition depending on what boundaries were used for resizing.
Note that I do not include a command to push /emmc/sdcard-backup back onto SD card. That is because:
There may not be enough room on /sdcard after a FAT32 downsize, and
There may be a data conflict when flashing a different dual boot configuration as opposed to an updated one. But at least there is a full backup of /sdcard FAT32 --- assuming emmc has enough room to host it.
Presently there is no logic to detect the storage limits of the /emmc and /sdcard filesystems. I will leave that to you.
SO... if for ANY reason you are NOT comfortable with the potential changes outlined above, I recommend that you please STOP HERE and consider researching this topic further until you are comfortable.
For those willing and able to give this a try, I strongly recommend first performing an ADB-assisted run (i.e. with a computer hosting Android SDK Platform Tools) using an SD card with at least 4GB open (to be safe) AND with enough room on emmc to host a FULL backup of your entire /sdcard filesystem (/sdcard and all its subdirectories).
Fully charge your battery! CWM draws a lot of current, even if nothing else is running.

don't know if that is the correct place
Hello,
Thanks for your patch, I am facing an issue with my Atrix (Orange UK), I have scrued up my internal storage, here I have posted once a Question but got no reply from nobody (POST).
Am I right to ask here, or is it wrong place too

Hi everyone,
I'm trying to figure out if I can get my nook to be the ultimate upgrade on a 160gb Ipod, that is to get it to work with an external battery powering a 200gb or higher 2.5" external hard drive.
and then using audio through USB.
Do you know if that is theorically possible? (power wouldnt be an issue with external power but maybe the nook just can't recognize any external storage beyond a certain capacity)
the info is probably out there somewhere but I'm sad to say I don't know enough to understand most of what I find on the board (yet)
please tell me it's possible !
cheers
I don't see why it wouldn't work.
USB mass storage should all be the same.
You'll need to mount it.
I'll have to borrow a 2.5" disk in a USB enclosure and try it today.
Hi Renate,
Great! thanks for your reply
and wow! thanks for looking into this!
I'll have to wait till next month to give it a try, the idea is to build some sort of portable dock (using the slots meant for the nook cases) with battery/USB hub/hard drive and jack audio output so I can use the nook+dock as a unit, just the dock as music library on my laptop or just the nook for reading.
I've been dreaming of an e-ink computer for some time, the three main things I needed were a keyboard, and sound output (both of which you already took care of, and mass storage) if you tell me it works I'll post a guide on how to get that done.
I have a 2.5" disk out of an old laptop in a USB.
It has 3 partitions on it.
Yes, it works fine on FAT, FAT32 & NTFS
If you use this a lot, you might want to put a mkdir for the mount point in init.rc before the root goes ro.
This is how you have to mount it if you have to do all the steps.
Code:
mount -o rw,remount rootfs /
mkdir /usb
mount -t vfat /dev/block/uba1 /usb
Change vfat to ntfs if applicable.
Thanks a lot Renate,
I don't quite understand everything yet, but I'll get there (there's plenty to read on this board) don't bother explaining, if you start you'll never see the end of it.
Now I suppose the big question is : can the nook touch take a 300gb itunes library? I'll get back to you on that
cheers
I tried this script
mount -o rw,remount rootfs /
mkdir /usbdisk
mount -o rw,iocharset=utf8 -t vfat /dev/block/uba1 /usbdisk
Click to expand...
Click to collapse
for fat32 hard disks - 500 and 1000gb and work perfect
but for ntfs
mount -o rw,remount rootfs /
mkdir /usbdisk
mount -o rw,iocharset=utf8 -t ntfs /dev/block/uba1 /usbdisk
Click to expand...
Click to collapse
script works without errors but usbdisk folder remained empty.
where I do mistake? please advice.
Try without any of the options.
It may be that with the default driver NTFS can only be mounted read-only.
Code:
mount -t ntfs /dev/block/uba1 /usbdisk

Does this just work on top of a plain rooted 1.1.2, or do I also need some additional apk?
It should work on anything.

What I meant to ask was if the above process (to mount an external drive on the NST) was contingent on the prerequisite "to first get my NST to support USB Host Mode"?
Yes, to get a disk drive working you need to somehow get the Nook to be a USB host.
The straight forward way is to install verygreen & mali100's uImage and then use my UsbMode.apk to switch it into host mode.
This is all detailed in another thread: http://forum.xda-developers.com/showthread.php?t=1457971
You'll need a powered hub if you want to run a disk drive.
If you know what you are doing and you use a back-powering hub you can get the Nook to kick into USB host mode without any modifications or apps.
Oh, yeah, of course an OTG adapter is required for any of this.
Thanks for reply/pointer.
I found the usb-host-mt-pack_0.1.zip.
I assume I should replace the NullKbd-1.1.apk and UsbMode-1.2.apk in the zip file with their corresponding newer versions NullKbd-1.2.apk and UsbMode-1.6.apk?

You probably have multiple partitions on the drive.
Try:
Code:
busybox fdisk -l /dev/block/uba1
Then you'll have to do something like:
Code:
mount -t ntfs /dev/block/uba1p1 /usb

Is there another way to auto-create a persistent mount point without fiddling with unpacking/repacking uRamdisk to apply the snippet to its init.rc copy?

Certainly. Just do it in init.rc before the root is mounted read-only.
Code:
[b]mkdir /usb 0777 system system[/b]
mount rootfs rootfs / ro remount
(init.rc is in uRamdisk in the boot partition.
use bootutil.exe to extract and replace the init.rc)
I've an SM-N910F with rooted TouchWiz 6.0.1 XXS1DPK1 and I'm finding big problems on properly mount (or better to say "manage") my Ext4 formatted MicroSD.
I run:
Code:
mkdir /data/media/extSdCard
chown root:sdcard_rw /data/media/extSdCard
chmod 775 /data/media/extSdCard
mount -w -t ext4 /dev/block/mmcblk1p1 /data/media/extSdCard
The card is now mounted and accesible but vold daemon still can't see it. Without vold maybe the volume is unknown to all apps and effectively unusable out of just file transfer ...
Is there a way to force vold daemon to manage it?? Or am I doing some mistake on mounting properly my Ext4 formatted MicroSD?
Thanks for helping ...
