Hello!

Please help me to get back access to internal flash storage on my aPad Batch3 with bootloader version 3.27.

I'm just formated it from Mac OsX and now "Preferences" show 0 byte are free. Currently the Disk Manager on Windows
over USB connection to aPad are detect two disks. One of them is an external micro SD card and the second unknown without inserted media.
Possible the second is an internal flash storage, but Windows can't format or partition it doe "out of media" status.

Is it possible to use an android sdk tool "adb" for recreating and reformating internal flash storage or any other way to get it working back exist?

The reflashing aPad by the new firmware didn't repair internal flash.

Thanks for any help.

UPD.

The storage was reformated with adb.

1.Install android-sdk (and drivers if your using Windows) on your Mac or PC computer
2. connect aPad via USB to the computer and don't mount flash cards
3. Open terminal and start adb with "shell" key.
4. Serach inside /dev/block on the aPad for the internal flash storage (For me it was a /dev/block/vold/31:8 )
5. Run reformating by the "mkdosfs -F 32 /dev/path_to_the_storage " command (for me "mkdosfs -F 32 /dev/block/vold/31:8/")

when you get a parameters list of the formated volume type "exit", disconnect USB cable form aPad and reboot it.
After rebooting internal flash storage should work correct.

Never format it again with Mac o Linux  :(

Big thanks to Kroligoff from ruandroid.org for the help!

I don't have this tablet, but looking at the first post, did you do step 4? Are you sure your internal storage is at /dev/block/vold/31:8?
