how to restore raspberry pi sd card from dmg file size

Put your microSD card into an adapter/card reader and connect to your pc.(If Services like Airplay work, Hybrid Objects should work). If that doesn't work, paste the output from fdisk -l into your question.Install Windows: Make an Arduino Yun in to a Hybrid Object Once that's done you should be able to mount it with sudo mount /dev/sdb2 /mnt/whatever, where /mnt/whatever is an empty existing directory. This may ask you about making repairs, these are usually not too many. Then try sudo e2fsck /dev/sdb2 this is to check the filesystem on the second partition. You'll see a table which describes your SD card, the little vfat partition and the big ext4 one ( fdisk may refer to the latter as just 'Linux' but the size should be correct). This is the device node without the partition number at the end. You can then double check that with sudo fdisk -l /dev/sdb. If you are using a USB adapter, it will instead be an sd device, sda or sdb etc. If your computer has an SD card slot the device will probably be similar to what it is on the Pi, mmcblk0, then the two partitions will be mmcblk0p1 and mmcblk0p2. Then put it in, and run ls -1 /dev > dev2.txt You haven't explained how you opened it, but if you can find the boot partition on linux you should be able to find the root fs.įirst you need to figure out what the device node is, an easy way to do this if you are not sure is to run: ls -1 /dev > dev1.txt When I open it on windows or Linux system it only shows one boot partition I will be very thankful to one who solve my problem! If yes kindly provide me solution of that. Is there any way to recover that programming file. So the next command sudo mount /dev/sdb2 /mnt/whatever not work and showed that mount: /mnt/whatever: mount point does not exist. Then I used sudo e2fsck /dev/sdb2, it showed rootfs: **** WARNING: Filesystem still has errors ***** When I paste this command in terminal: sudo fdisk -l /dev/sdb it showed sdb1 and sdb2 partitions. I also tried this solution that is given in answer but it didn't work: When I open it on windows or Linux system via SD card reader or USB card reader it only shows one boot partition containing all those files that are usually reside when we first time write SD card with raspbian operating system. I tried many ways to recover that file also, I don't find solution of it.

Now the issue is I did lot of programming work on it and my program file is reside in it.

This is the error end Kernel panic - not sycing: VFS: Unable to mount root fs on unknown-black(179,2) I tried many wasy to boot it that are given on internet, no solution work.
