What is "Data partition" on the HDD/250GB model? - Gen8, Gen9, Gen10 Q&A, Help & Troubleshooting

The Recovery mode, on A101H, offers to export Data Partition, and also Export Hard Disk. The Hard Disk is clear ... on the host/linux I see the disk device (say sdb) and the partition (sdb1). But what am I accessing, when the Data Partition is exported? If it's not on the har disk (sdb), what is it?

It's the same as in flash model- internal flash partition 4 (mmcblk0p4, ext4) but smaller- ~1.5GB IIRC

[Q] Link2SD CM7 v1.9 hf3 i5500

Sorry if i sound like a noob but can i take advantage of the ext3 partition on my SD using this version of CM?
I partitioned my SD using clockworkmod, which is why it's ext3.
only app i've tried is Link2SD but when i tell it there is an ext3 partition on the card it creates a script and asks me to reboot.
Once that's done and i access the app again it goes through the same motions and informs me that - "if im seeing this message then the partition is unable to be mounted during boot"
Appreciate any help
Here's a quick way to install Link2sd.
I preassume that your device is rooted and your sdcard data is backed up.I think,the mount script didn't work because of inappropriate attributes..Ok heres,how i installed Link2sd...
1.First of all download and install MiniTool Partition Wizard in your windows PC.
Connect your handset to the PC via USB.
2.Launch MiniTool Partition,you should see your SDcard mentioned in the list Under Disk 2 probably.
3.Right click your SDcard mentioned in the list, press "Move/Resize Partition"
4.In the Partition size,allocate bigger chunk of partition for primary partition.This is the partition your phone will access for general purpose.Say you allocate 7GB from your 8GB memory card.
Click OK.
5.Now Under disk 2. you will see and unpartitioned space of about 1GB.This partition will be used by link2sd.You may allocate your sdcard as you may wish.
6.Right click the upartitioned space to create a new partition under "Create As".If a warning popup asks for permission click YES.
7.Under New window Create As,choose "Primary".For File System type choose 'FAT32'.though you may choose among ext3 or ext4,either is supported by link2sd.NTFS is not supported by Link2sd or android OS.For partition size take whole unallocated space.Click on OK
8.Click Apply button<upper left corner in the screen>.
9.Restart your phone.
Again use your Link2sd app to create mount script.Now your app should work fine.
Don't forget to hit THANKS if i helped you.
I would not suggest you to create the Link2sd partition as a FAT32 one: this way when you will connect your phone to a PC through the USB cable Windows will mount all the 2 partitions automatically (with all negative consequences you can imagine); this issue will not happen on Linux, however; while with the Link2sd partition formatted as extX you will be able to use your linked apps while the phone is connected to your PC and the first partition is mounted, it doesn't matter if you are on Linux or Windows (tested )
Regarding your problem: try to tell the Link2sd script activator that your partition is an ext4 and see if it works.. I hope so, anyway let us know..
@brainvision
yeah thanks,extX would be better..bt i think windows doesn't mount two sdcard Fat32 partition at a time.i may be wrong in this term, bt sometime back,when i used to use rooted android 2.1,windows would mount only my 1st primary partition of sdcard..however under ubuntu..both partition would load bt without affecting the phone apps.

oh sorry I'm not a winZoZZ user since a lot of time!! I'm a slacker now!!
Regarding Linx OS: I set up my Slackware so that it doesn't auto mount external disk, so i can plug in the phone and activate the USB Mass storage without still mounting it: this way I can mount only the first partition; but in a auto-mount situation I fear that the the phone apps would be affected by USB Mass storage activation!

[Q]full wipe, when having a swap partition.

Hi, just wondering if is just my case, that when doing a full wipe from the recovery and having a swap partition, this partition gets formated in ext3, has someone experience this? is this normal? thanks.
Experienced something similar. When full wipe data, minicm7 tells me I have 500MB large EXT partition.
In PC memory card still formated as "linux swap".
I formated card and created swap partition again and after that phone recognized it right - as swap - again.
Yeah, my phone did that. I fixed it. By doing this:
I made my 15GB fat data partition, a 1MB EXT4 for /sd-ext not to be used but stops phone formatting swap as ext. Then my 500MB swap partition. This works

yeah... I have started using swap not so long ago, and I tend to flash and reflash roms, and always when doing the full wipe the partition ends formated, so I unplug the sd from the phone, mount it in the pc, reformat the partition as swap, mount it on the phone restart it and it remount it again as swap (sometimes I need to do it twice).
going to try making the 1MB partition the next time.

[Q] Restore SD card to its original size

In order to recover my Android TV box I've tried to copy a recovery image on to my 16GB SD card using a tool called HDD RAW Copy.
Having not been able to recover my TV box, I also haven't been able to reformat my SD card back to its original size. Windows 7 only reads 3.68GB while its actual size should be ~16GB. I have tried to wipe all of its data and see if there were any hidden partitions. I have used EASEUS Partition Manager for that, but that tool couldn't find any. Formatting the SD card to NTFS didn't make a difference in size either.
I am quite out of ideas. Can anyone help?

Just open a cmd prompt (as Administrator) and give the command diskpart.Then give the following commands:
list disk
This command will print all your connected disks.
select disk {the disk number you see for the device you want to restore}
With this command you select the disk you want to edit.
clean
This command will clean all your partitions on your sdcard.
***Attention: Don't try this command on some other disk by accident / If you are not sure don't try it***
You could give a command like list partition to make sure you are in the correct disk.
Then type:
Code:
create partition primary
format fs=fat32 quick
exit
And you are done!
After doing a CLEAN ALL command the size of the SD card is still 3,69GB.

Try some linux application to clear partition table and recreate the partition.You can download a gparted live cd/dvd if you like.If that doesn't work for you I am afraid your sdcard could be destroyed.
**I assume you are using an adaptor to connect the sdcard to your PC.Don't try ro mount it from recovery.**
Thanks! That did the trick! :good:

25 GB unused internal partition?

I see in the partition table cat /proc/partitions a disk sda of about 25GB
...
8 0 25833472 sda
8 1 8 sda1
...
8 9 25536204 sda9
Is this space usable in any way? Or is this somehow the same as the dm-0 partition that is mounted to /SDCARD. Sda9 is not getting mounted. And I cannot find out what the type of disk is.
Or better: where do I find a description of the internal disk setup of the lemax2?
thanks in advance for your feedback,
Walter

Heyyo, EUI ROM chinese versions have a lot of bloatware that get their own partition...
The easiest solution is to do a format data via TWRP. It corrects the data partition and gives you full access to it again.
Doing a data wipe via TWRP does not solve the issue. Only formatting data partition does.

Thanks for the feedback.
I did do a format of data; that solved an issue with the data partition only showing 10gb, not 25gb.
So the situation I am showing is after the data format.
After the format there is still the sda disk of which no partition is mounted and the dm-0 data partition of 25gb.

Ah for that then I'm not too sure. Might be a question that is better suited to one of the skilled developers of ROMs as I have only tinkered

Storage issue

I have the 32GB varient,
the usable Internal storage it shows is 23GB,
remaining free space it shows is: 2.9GB,
It is rooted, and I selected all files and folders (hidden files included) on Internal storage to check there total size:
it shows 10.04GB (on both ES and X-plore)
So,
out of 32GB, I only get 23GB for myself (lets just give 9GB away for the system, no big deal)
out of 23GB, I used 10.04GB and the remaining free space is just 2.9GB
So, 10.04+2.9 = 12.94GB, is all I get to use ? out of freakin 23GB ?!
Why !? Where the hell did 23-12.94 = 10.06GB go ?!!!
now, please dont tell me that the OS needs 9GB+10.06 = 19.06GB for the device to work correctly !
That too out of freakin 32GB ! Why would anyone call this phone a 32GB varient now ?
PS: I suck at maths.
It is something wrong to your data partition. try to fix it by using command flash 'fastboot flash data.img' separately over fastboot mode
extract data.img from the ROM you using

Of course, without wipe & erase data partition you cannot fix the issue since it is the wrong info of data partition leading to the OS cannot recognize the full size of data partition.
