Create image of flash drive / Memory card in linux.

Hi guys sometime we need to make image of memory card, pendrive or any flash device.
There is a tools in linux by which we can easily make images.

1. Insert memory card / flash drive in card reader or usb.
2. Now open terminal window using ("ctrl + alt + t" in ubuntu).
3. make a directory at desktop where we will save image by following commands:
• sudo mkdir ~/Desktop/backupImages
• cd ~/Desktop/backupImages
4. give command clear"dmesg"
• dmesg -C
• dmesg

• You will find result "attached scsi removable disk". Here "sdd" is found on my pc.
• Make sure you check on your computer. "Careful in this step to get your device name"

• Now give command to make image of your device
• sudo dd if=/dev/sdd of=myflashbackup.img
• now wait for few minutes depending upon size of flash drive.
• A new file is created named "myflashbackup.img".

Note: "if" is source and "of" is destination.

please post if having any query.
