Cannot mount encrypted microsd card in ubuntu 11.04 : File system issue

[dhruvwali]

I encrypted my microsd card in ubuntu (cryptoluks) using fat as the filesystem. Then I plugged the microsd into my android phone. As it did not detect the filesystem.. ( encrypted?) I again inserted the microsd card into the laptop / UBUNTU 11.04

Now whenever i plug in the device , it does not get mounted and gives the error :-

Unable to mount 32 GB Unrecognized Error mounting: mount: you must specify the filesystem type

I suppose that the file system is corrupted ... I checked in the Disk Utility and it doesnt show any filesystem.. Only gives me option to format/change the password..

I have valuable data in my memory card that I have to recover .. It doesnt open in windows as well - tells me to format..

Please help!!

Download this Windows program and see if it can recover the files. It should work.

Did you format it as FAT or FAT32? I dont believe Android reads FAT, as its ancient and hardly found used on anything these days. Is your phone rooted? If so, you should be able to format it through the recovery system when you first boot the phone.

He doesn't want to format it, he wants his data that's on it.

You could try adding it to fstab.
First, you will need to view all of your partitions.

sudo fdisk -l

Your SD card should show up in here when its inserted. Note the partition number of the card. I will use sdx1 in my example below.

sudo nano /etc/fstab

Now, add this to the bottom of your fstab file. Substitute sdx1 with whatever label your SD card is assigned.

/dev/sdx1   /media/sdcard  vfat   defaults   0   0

Now you will make a directory to mount the SD card, probably best under /media/sdcard

sudo mkdir /media/sdcard

After that, we need to mount the SD card

sudo mount /media/sdcard

AFter that, you should be able to navigate to the SD card and view its contents.

Once you have backed up the contents of your SD card, unmount it.

sudo umount /media/sdcard

Now you may remove the SD card, insert it into your phone, and reformat it. In the meantime, remove the directory you created for the SD card, and delete the entry from fstab.
